2 - kubectl annotate
Synopsis
Update the annotations on one or more resources.
All Kubernetes objects support the ability to store additional data with the object as annotations. Annotations are key/value pairs that can be larger than labels and include arbitrary string values such as structured JSON. Tools and system extensions may use annotations to store their own data.
Attempting to set an annotation that already exists will fail unless --overwrite is set. If --resource-version is specified and does not match the current resource version on the server the command will fail.
Use "kubectl api-resources" for a complete list of supported resources.
kubectl annotate [--overwrite] (-f FILENAME | TYPE NAME) KEY_1=VAL_1 ... KEY_N=VAL_N [--resource-version=version]
Examples
# Update pod 'foo' with the annotation 'description' and the value 'my frontend'
# If the same annotation is set multiple times, only the last value will be applied
kubectl annotate pods foo description='my frontend'
# Update a pod identified by type and name in "pod.json"
kubectl annotate -f pod.json description='my frontend'
# Update pod 'foo' with the annotation 'description' and the value 'my frontend running nginx', overwriting any existing value
kubectl annotate --overwrite pods foo description='my frontend running nginx'
# Update all pods in the namespace
kubectl annotate pods --all description='my frontend running nginx'
# Update pod 'foo' only if the resource is unchanged from version 1
kubectl annotate pods foo description='my frontend running nginx' --resource-version=1
# Update pod 'foo' by removing an annotation named 'description' if it exists
# Does not require the --overwrite flag
kubectl annotate pods foo description-
Options

| --dry-run string[="unchanged"] Default: "none" | |
Must be "none", "server", or "client". If client strategy, only print the object that would be sent, without sending it. If server strategy, submit server-side request without persisting the resource. | |
| --field-manager string Default: "kubectl-annotate" | |
Name of the manager used to track field ownership. | |
| --field-selector string | |
Selector (field query) to filter on, supports '=', '==', and '!='.(e.g. --field-selector key1=value1,key2=value2). The server only supports a limited number of field queries per type. | |

| --overwrite | |
If true, allow annotations to be overwritten, otherwise reject annotation updates that overwrite existing annotations. | |
| -R, --recursive | |
Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory. | |
| --resource-version string | |
If non-empty, the annotation update will only succeed if this is the current resource-version for the object. Only valid when specifying a single resource. | |
| -l, --selector string | |
Selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2). Matching objects must satisfy all of the specified label constraints. | |
| --show-managed-fields | |
If true, keep the managedFields when printing objects in JSON or YAML format. | |
| --template string | |
Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview]. | |

5 - kubectl apply
Synopsis
Apply a configuration to a resource by file name or stdin. The resource name must be specified. This resource will be created if it doesn't exist yet. To use 'apply', always create the resource initially with either 'apply' or 'create --save-config'.
JSON and YAML formats are accepted.
Alpha Disclaimer: the --prune functionality is not yet complete. Do not use unless you are aware of what the current state is. See https://issues.k8s.io/34274.
kubectl apply (-f FILENAME | -k DIRECTORY)
Examples
# Apply the configuration in pod.json to a pod
kubectl apply -f ./pod.json
# Apply resources from a directory containing kustomization.yaml - e.g. dir/kustomization.yaml
kubectl apply -k dir/

5.1 - kubectl apply edit-last-applied
Synopsis
Edit the latest last-applied-configuration annotations of resources from the default editor.
The edit-last-applied command allows you to directly edit any API resource you can retrieve via the command-line tools. It will open the editor defined by your KUBE_EDITOR, or EDITOR environment variables, or fall back to 'vi' for Linux or 'notepad' for Windows. You can edit multiple objects, although changes are applied one at a time. The command accepts file names as well as command-line arguments, although the files you point to must be previously saved versions of resources.
The default format is YAML. To edit in JSON, specify "-o json".
The flag --windows-line-endings can be used to force Windows line endings, otherwise the default for your operating system will be used.
In the event an error occurs while updating, a temporary file will be created on disk that contains your unapplied changes. The most common error when updating a resource is another editor changing the resource on the server. When this occurs, you will have to apply your changes to the newer version of the resource, or update your temporary saved copy to include the latest resource version.
kubectl apply edit-last-applied (RESOURCE/NAME | -f FILENAME)

7.1 - kubectl auth can-i
Synopsis
Check whether an action is allowed.
VERB is a logical Kubernetes API verb like 'get', 'list', 'watch', 'delete', etc. TYPE is a Kubernetes resource. Shortcuts and groups will be resolved. NONRESOURCEURL is a partial URL that starts with "/". NAME is the name of a particular Kubernetes resource. This command pairs nicely with impersonation. See --as global flag.
kubectl auth can-i VERB [TYPE | TYPE/NAME | NONRESOURCEURL]
Examples
# Check to see if I can create pods in any namespace
kubectl auth can-i create pods --all-namespaces
# Check to see if I can list deployments in my current namespace
kubectl auth can-i list deployments.apps
# Check to see if service account "foo" of namespace "dev" can list pods in the namespace "prod"
# You must be allowed to use impersonation for the global option "--as"
kubectl auth can-i list pods --as=system:serviceaccount:dev:foo -n prod
# Check to see if I can do everything in my current namespace ("*" means all)
kubectl auth can-i '*' '*'
# Check to see if I can get the job named "bar" in namespace "foo"

7.2 - kubectl auth reconcile
Synopsis
Reconciles rules for RBAC role, role binding, cluster role, and cluster role binding objects.
Missing objects are created, and the containing namespace is created for namespaced objects, if required.
Existing roles are updated to include the permissions in the input objects, and remove extra permissions if --remove-extra-permissions is specified.
Existing bindings are updated to include the subjects in the input objects, and remove extra subjects if --remove-extra-subjects is specified.
This is preferred to 'apply' for RBAC resources so that semantically-aware merging of rules and subjects is done.

8 - kubectl autoscale
Synopsis
Creates an autoscaler that automatically chooses and sets the number of pods that run in a Kubernetes cluster.
Looks up a deployment, replica set, stateful set, or replication controller by name and creates an autoscaler that uses the given resource as a reference. An autoscaler can automatically increase or decrease number of pods deployed within the system as needed.

Examples
# Auto scale a deployment "foo", with the number of pods between 2 and 10, no target CPU utilization specified so a default autoscaling policy will be used
kubectl autoscale deployment foo --min=2 --max=10

9.1 - kubectl certificate approve
Synopsis
Approve a certificate signing request.
kubectl certificate approve allows a cluster admin to approve a certificate signing request (CSR). This action tells a certificate signing controller to issue a certificate to the requester with the attributes requested in the CSR.
SECURITY NOTICE: Depending on the requested attributes, the issued certificate can potentially grant a requester access to cluster resources or to authenticate as a requested identity. Before approving a CSR, ensure you understand what the signed certificate can do.

10.1 - kubectl cluster-info dump
Synopsis
Dump cluster information out suitable for debugging and diagnosing cluster problems. By default, dumps everything to stdout. You can optionally specify a directory with --output-directory. If you specify a directory, Kubernetes will build a set of files in that directory. By default, only dumps things in the current namespace and 'kube-system' namespace, but you can switch to a different namespace with the --namespaces flag, or specify --all-namespaces to dump all namespaces.
The command also dumps the logs of all of the pods in the cluster; these logs are dumped into different directories based on namespace and pod name.
kubectl cluster-info dump [flags]
Examples
# Dump current cluster state to stdout
kubectl cluster-info dump
# Dump current cluster state to /path/to/cluster-state
kubectl cluster-info dump --output-directory=/path/to/cluster-state

11 - kubectl completion
Synopsis
Output shell completion code for the specified shell (bash, zsh, fish, or powershell). The shell code must be evaluated to provide interactive completion of kubectl commands. This can be done by sourcing it from the .bash_profile.
Detailed instructions on how to do this are available here:
for macOS:
https://kubernetes.io/docs/tasks/tools/install-kubectl-macos/#enable-shell-autocompletion
for linux:
https://kubernetes.io/docs/tasks/tools/install-kubectl-linux/#enable-shell-autocompletion
for windows:

## If kubectl is installed via homebrew, this should start working immediately
## If you've installed via other means, you may need add the completion to your completion directory
kubectl completion bash > $(brew --prefix)/etc/bash_completion.d/kubectl
# Installing bash completion on Linux
## If bash-completion is not installed on Linux, install the 'bash-completion' package
## via your distribution's package manager.
## Load the kubectl completion code for bash into the current shell
source <(kubectl completion bash)
## Write bash completion code to a file and source it from .bash_profile
kubectl completion bash > ~/.kube/completion.bash.inc

Synopsis
Modify kubeconfig files using subcommands like "kubectl config set current-context my-context".
The loading order follows these rules:
- If the --kubeconfig flag is set, then only that file is loaded. The flag may only be set once and no merging takes place.
- If $KUBECONFIG environment variable is set, then it is used as a list of paths (normal path delimiting rules for your system). These paths are merged. When a value is modified, it is modified in the file that defines the stanza. When a value is created, it is created in the first file that exists. If no files in the chain exist, then it creates the last file in the list.
- Otherwise, ${HOME}/.kube/config is used and no merging takes place.

12.9 - kubectl config set
Synopsis
Set an individual value in a kubeconfig file.
PROPERTY_NAME is a dot delimited name where each token represents either an attribute name or a map key. Map keys may not contain dots.
PROPERTY_VALUE is the new value you want to set. Binary fields such as 'certificate-authority-data' expect a base64 encoded string unless the --set-raw-bytes flag is used.
Specifying an attribute name that already exists will merge new fields on top of existing values.
kubectl config set PROPERTY_NAME PROPERTY_VALUE
Examples
# Set the server field on the my-cluster cluster to https://1.2.3.4
kubectl config set clusters.my-cluster.server https://1.2.3.4
# Set the certificate-authority-data field on the my-cluster cluster
kubectl config set clusters.my-cluster.certificate-authority-data $(echo "cert_data_here" | base64 -i -)
# Set the cluster field in the my-context context to my-cluster
kubectl config set contexts.my-context.cluster my-cluster
# Set the client-key-data field in the cluster-admin user using --set-raw-bytes option

15.3 - kubectl create configmap
Synopsis
Create a config map based on a file, directory, or specified literal value.
A single config map may package one or more key/value pairs.
When creating a config map based on a file, the key will default to the basename of the file, and the value will default to the file content. If the basename is an invalid key, you may specify an alternate key.
When creating a config map based on a directory, each file whose basename is a valid key in the directory will be packaged into the config map. Any directory entries except regular files are ignored (e.g. subdirectories, symlinks, devices, pipes, etc).
kubectl create configmap NAME [--from-file=[key=]source] [--from-literal=key1=value1] [--dry-run=server|client|none]
Examples
# Create a new config map named my-config based on folder bar
kubectl create configmap my-config --from-file=path/to/bar
# Create a new config map named my-config with specified keys instead of file basenames on disk
kubectl create configmap my-config --from-file=key1=/path/to/bar/file1.txt --from-file=key2=/path/to/bar/file2.txt
# Create a new config map named my-config with key1=config1 and key2=config2
kubectl create configmap my-config --from-literal=key1=config1 --from-literal=key2=config2
# Create a new config map named my-config from the key=value pairs in the file
kubectl create configmap my-config --from-file=path/to/bar
# Create a new config map named my-config from an env file
kubectl create configmap my-config --from-env-file=path/to/foo.env --from-env-file=path/to/bar.env

15.15 - kubectl create secret docker-registry
Synopsis
Create a new secret for use with Docker registries.
Dockercfg secrets are used to authenticate against Docker registries.
When using the Docker command line to push images, you can authenticate to a given registry by running:
'$ docker login DOCKER_REGISTRY_SERVER --username=DOCKER_USER --password=DOCKER_PASSWORD --email=DOCKER_EMAIL'.
That produces a ~/.dockercfg file that is used by subsequent 'docker push' and 'docker pull' commands to authenticate to the registry. The email address is optional.
When creating applications, you may have a Docker registry that requires authentication. In order for the
nodes to pull images on your behalf, they must have the credentials. You can provide this information
by creating a dockercfg secret and attaching it to your service account.
kubectl create secret docker-registry NAME --docker-username=user --docker-password=password --docker-email=email [--docker-server=string] [--from-file=[key=]source] [--dry-run=server|client|none]
Examples
# If you do not already have a .dockercfg file, create a dockercfg secret directly
kubectl create secret docker-registry my-secret --docker-server=DOCKER_REGISTRY_SERVER --docker-username=DOCKER_USER --docker-password=DOCKER_PASSWORD --docker-email=DOCKER_EMAIL
# Create a new secret named my-secret from ~/.docker/config.json
kubectl create secret docker-registry my-secret --from-file=path/to/.docker/config.json

15.16 - kubectl create secret generic
Synopsis
Create a secret based on a file, directory, or specified literal value.
A single secret may package one or more key/value pairs.
When creating a secret based on a file, the key will default to the basename of the file, and the value will default to the file content. If the basename is an invalid key or you wish to chose your own, you may specify an alternate key.
When creating a secret based on a directory, each file whose basename is a valid key in the directory will be packaged into the secret. Any directory entries except regular files are ignored (e.g. subdirectories, symlinks, devices, pipes, etc).

16 - kubectl debug
Synopsis
Debug cluster resources using interactive debugging containers.
'debug' provides automation for common debugging tasks for cluster objects identified by resource and name. Pods will be used by default if no resource is specified.
The action taken by 'debug' varies depending on what resource is specified. Supported actions include:
- Workload: Create a copy of an existing pod with certain attributes changed, for example changing the image tag to a new version.
- Workload: Add an ephemeral container to an already running pod, for example to add debugging utilities without restarting the pod.
- Node: Create a new pod that runs in the node's host namespaces and can access the node's filesystem.
kubectl debug (POD | TYPE[[.VERSION].GROUP]/NAME) [ -- COMMAND [args...] ]
Examples
# Create an interactive debugging session in pod mypod and immediately attach to it.
kubectl debug mypod -it --image=busybox
# Create an interactive debugging session for the pod in the file pod.yaml and immediately attach to it.
# (requires the EphemeralContainers feature to be enabled in the cluster)
kubectl debug -f pod.yaml -it --image=busybox
# Create a debug container named debugger using a custom automated debugging image.
kubectl debug --image=myproj/debug-tools -c debugger mypod
# Create a copy of mypod adding a debug container and attach to it
kubectl debug mypod -it --image=busybox --copy-to=my-debugger
# Create a copy of mypod changing the command of mycontainer
kubectl debug mypod -it --copy-to=my-debugger --container=mycontainer -- sh
# Create a copy of mypod changing all container images to busybox
kubectl debug mypod --copy-to=my-debugger --set-image=*=busybox
# Create a copy of mypod adding a debug container and changing container images
kubectl debug mypod -it --copy-to=my-debugger --image=debian --set-image=app=app:debug,sidecar=sidecar:debug
# Create an interactive debugging session on a node and immediately attach to it.
# The container will run in the host namespaces and the host's filesystem will be mounted at /host

17 - kubectl delete
Synopsis
Delete resources by file names, stdin, resources and names, or by resources and label selector.
JSON and YAML formats are accepted. Only one type of argument may be specified: file names, resources and names, or resources and label selector.
Some resources, such as pods, support graceful deletion. These resources define a default period before they are forcibly terminated (the grace period) but you may override that value with the --grace-period flag, or pass --now to set a grace-period of 1. Because these resources often represent entities in the cluster, deletion may not be acknowledged immediately. If the node hosting a pod is down or cannot reach the API server, termination may take significantly longer than the grace period. To force delete a resource, you must specify the --force flag. Note: only a subset of resources support graceful deletion. In absence of the support, the --grace-period flag is ignored.
IMPORTANT: Force deleting pods does not wait for confirmation that the pod's processes have been terminated, which can leave those processes running until the node detects the deletion and completes graceful deletion. If your processes use shared storage or talk to a remote API and depend on the name of the pod to identify themselves, force deleting those pods may result in multiple processes running on different machines using the same identification which may lead to data corruption or inconsistency. Only force delete pods when you are sure the pod is terminated, or if your application can tolerate multiple copies of the same pod running at once. Also, if you force delete pods, the scheduler may place new pods on those nodes before the node has released those resources and causing those pods to be evicted immediately.
Note that the delete command does NOT do resource version checks, so if someone submits an update to a resource right when you submit a delete, their update will be lost along with the rest of the resource.
After a CustomResourceDefinition is deleted, invalidation of discovery cache may take up to 6 hours. If you don't want to wait, you might want to run "kubectl api-resources" to refresh the discovery cache.
kubectl delete ([-f FILENAME] | [-k DIRECTORY] | TYPE [(NAME | -l label | --all)])
Examples
# Delete a pod using the type and name specified in pod.json
kubectl delete -f ./pod.json
# Delete resources from a directory containing kustomization.yaml - e.g. dir/kustomization.yaml
kubectl delete -k dir
# Delete resources from all files that end with '.json'
kubectl delete -f '*.json'
# Delete a pod based on the type and name in the JSON passed into stdin
cat pod.json | kubectl delete -f -
# Delete pods and services with same names "baz" and "foo"
kubectl delete pod,service baz foo
# Delete pods and services with label name=myLabel
kubectl delete pods,services -l name=myLabel
# Delete a pod with minimal delay
kubectl delete pod foo --now
# Force delete a pod on a dead node
kubectl delete pod foo --force
# Delete all pods
kubectl delete pods --all
Options
| --all | |

| --field-selector string | |
Selector (field query) to filter on, supports '=', '==', and '!='.(e.g. --field-selector key1=value1,key2=value2). The server only supports a limited number of field queries per type. | |
| -f, --filename strings | |
containing the resource to delete. | |
| --force | |
If true, immediately remove resources from API and bypass graceful deletion. Note that immediate deletion of some resources may result in inconsistency or data loss and requires confirmation. | |
| --grace-period int Default: -1 | |
Period of time in seconds given to the resource to terminate gracefully. Ignored if negative. Set to 1 for immediate shutdown. Can only be set to 0 when --force is true (force deletion). | |

help for delete | |
| --ignore-not-found | |
Treat "resource not found" as a successful delete. Defaults to "true" when --all is specified. | |

| -k, --kustomize string | |
Process a kustomization directory. This flag can't be used together with -f or -R. | |
| --now | |
If true, resources are signaled for immediate shutdown (same as --grace-period=1). | |
| -o, --output string | |
Output mode. Use "-o name" for shorter output (resource/name). | |
| --raw string | |
Raw URI to DELETE to the server. Uses the transport specified by the kubeconfig file. | |
| -R, --recursive | |
Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory. | |
| -l, --selector string | |
Selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2). Matching objects must satisfy all of the specified label constraints. | |
| --timeout duration | |
The length of time to wait before giving up on a delete, zero means determine a timeout from the size of the object | |

18 - kubectl describe
Synopsis
Show details of a specific resource or group of resources.
Print a detailed description of the selected resources, including related resources such as events or controllers. You may select a single object by name, all objects of that type, provide a name prefix, or label selector. For example:
$ kubectl describe TYPE NAME_PREFIX
will first check for an exact match on TYPE and NAME_PREFIX. If no such resource exists, it will output details for every resource that has a name prefixed with NAME_PREFIX.
Use "kubectl api-resources" for a complete list of supported resources.
kubectl describe (-f FILENAME | TYPE [NAME_PREFIX | -l label] | TYPE/NAME)
Examples
# Describe a node
kubectl describe nodes kubernetes-node-emt8.c.myproject.internal
# Describe a pod
kubectl describe pods/nginx
# Describe a pod identified by type and name in "pod.json"
kubectl describe -f pod.json
# Describe all pods
kubectl describe pods
# Describe pods by label name=myLabel

20 - kubectl drain
Synopsis
Drain node in preparation for maintenance.
The given node will be marked unschedulable to prevent new pods from arriving. 'drain' evicts the pods if the API server supports https://kubernetes.io/docs/concepts/workloads/pods/disruptions/ eviction https://kubernetes.io/docs/concepts/workloads/pods/disruptions/ . Otherwise, it will use normal DELETE to delete the pods. The 'drain' evicts or deletes all pods except mirror pods (which cannot be deleted through the API server). If there are daemon set-managed pods, drain will not proceed without --ignore-daemonsets, and regardless it will not delete any daemon set-managed pods, because those pods would be immediately replaced by the daemon set controller, which ignores unschedulable markings. If there are any pods that are neither mirror pods nor managed by a replication controller, replica set, daemon set, stateful set, or job, then drain will not delete any pods unless you use --force. --force will also allow deletion to proceed if the managing resource of one or more pods is missing.
'drain' waits for graceful termination. You should not operate on the machine until the command completes.
When you are ready to put the node back into service, use kubectl uncordon, which will make the node schedulable again.

kubectl drain NODE
Examples
# Drain node "foo", even if there are pods not managed by a replication controller, replica set, job, daemon set, or stateful set on it
kubectl drain foo --force
# As above, but abort if there are pods not managed by a replication controller, replica set, job, daemon set, or stateful set, and use a grace period of 15 minutes

21 - kubectl edit
Synopsis
Edit a resource from the default editor.
The edit command allows you to directly edit any API resource you can retrieve via the command-line tools. It will open the editor defined by your KUBE_EDITOR, or EDITOR environment variables, or fall back to 'vi' for Linux or 'notepad' for Windows. When attempting to open the editor, it will first attempt to use the shell that has been defined in the 'SHELL' environment variable. If this is not defined, the default shell will be used, which is '/bin/bash' for Linux or 'cmd' for Windows.
You can edit multiple objects, although changes are applied one at a time. The command accepts file names as well as command-line arguments, although the files you point to must be previously saved versions of resources.
Editing is done with the API version used to fetch the resource. To edit using a specific API version, fully-qualify the resource, version, and group.
The default format is YAML. To edit in JSON, specify "-o json".
The flag --windows-line-endings can be used to force Windows line endings, otherwise the default for your operating system will be used.
In the event an error occurs while updating, a temporary file will be created on disk that contains your unapplied changes. The most common error when updating a resource is another editor changing the resource on the server. When this occurs, you will have to apply your changes to the newer version of the resource, or update your temporary saved copy to include the latest resource version.
kubectl edit (RESOURCE/NAME | -f FILENAME)
Examples
# Edit the service named 'registry'
kubectl edit svc/registry
# Use an alternative editor
KUBE_EDITOR="nano" kubectl edit svc/registry
# Edit the job 'myjob' in JSON using the v1 API format
kubectl edit job.v1.batch/myjob -o json
# Edit the deployment 'mydeployment' in YAML and save the modified config in its annotation

25 - kubectl expose
Synopsis
Expose a resource as a new Kubernetes service.
Looks up a deployment, service, replica set, replication controller or pod by name and uses the selector for that resource as the selector for a new service on the specified port. A deployment or replica set will be exposed as a service only if its selector is convertible to a selector that service supports, i.e. when the selector contains only the matchLabels component. Note that if no port is specified via --port and the exposed resource has multiple ports, all will be re-used by the new service. Also if no labels are specified, the new service will re-use the labels from the resource it exposes.
Possible resources include (case insensitive):
pod (po), service (svc), replicationcontroller (rc), deployment (deploy), replicaset (rs)
kubectl expose (-f FILENAME | TYPE NAME) [--port=port] [--protocol=TCP|UDP|SCTP] [--target-port=number-or-name] [--name=name] [--external-ip=external-ip-of-service] [--type=type]
Examples
# Create a service for a replicated nginx, which serves on port 80 and connects to the containers on port 8000
kubectl expose rc nginx --port=80 --target-port=8000
# Create a service for a replication controller identified by type and name specified in "nginx-controller.yaml", which serves on port 80 and connects to the containers on port 8000
kubectl expose -f nginx-controller.yaml --port=80 --target-port=8000
# Create a service for a pod valid-pod, which serves on port 444 with the name "frontend"
kubectl expose pod valid-pod --port=444 --name=frontend
# Create a second service based on the above service, exposing the container port 8443 as port 443 with the name "nginx-https"
kubectl expose service nginx --port=443 --target-port=8443 --name=nginx-https
# Create a service for a replicated streaming application on port 4100 balancing UDP traffic and named 'video-stream'.
kubectl expose rc streamer --port=4100 --protocol=UDP --name=video-stream
# Create a service for a replicated nginx using replica set, which serves on port 80 and connects to the containers on port 8000
kubectl expose rs nginx --port=80 --target-port=8000

26 - kubectl get
Synopsis
Display one or many resources.
Prints a table of the most important information about the specified resources. You can filter the list using a label selector and the --selector flag. If the desired resource type is namespaced you will only see results in the current namespace if you don't specify any namespace.
By specifying the output as 'template' and providing a Go template as the value of the --template flag, you can filter the attributes of the fetched resources.
Use "kubectl api-resources" for a complete list of supported resources.

# Partially update a node using a strategic merge patch, specifying the patch as YAML
kubectl patch node k8s-node-1 -p $'spec:\n unschedulable: true'
# Partially update a node identified by the type and name specified in "node.json" using strategic merge patch
kubectl patch -f node.json -p '{"spec":{"unschedulable":true}}'
# Update a container's image; spec.containers[*].name is required because it's a merge key
kubectl patch pod valid-pod -p '{"spec":{"containers":[{"name":"kubernetes-serve-hostname","image":"new image"}]}}'
# Update a container's image using a JSON patch with positional arrays
kubectl patch pod valid-pod --type='json' -p='[{"op": "replace", "path": "/spec/containers/0/image", "value":"new image"}]'

33 - kubectl port-forward
Synopsis
Forward one or more local ports to a pod.
Use resource type/name such as deployment/mydeployment to select a pod. Resource type defaults to 'pod' if omitted.
If there are multiple pods matching the criteria, a pod will be selected automatically. The forwarding session ends when the selected pod terminates, and a rerun of the command is needed to resume forwarding.

34 - kubectl proxy
Synopsis
Creates a proxy server or application-level gateway between localhost and the Kubernetes API server. It also allows serving static content over specified HTTP path. All incoming data enters through one port and gets forwarded to the remote Kubernetes API server port, except for the path matching the static content path.
kubectl proxy [--port=PORT] [--www=static-dir] [--www-prefix=prefix] [--api-prefix=prefix]
Examples
# To proxy all of the Kubernetes API and nothing else
kubectl proxy --api-prefix=/
# To proxy only part of the Kubernetes API and also some static files
# You can get pods info with 'curl localhost:8001/api/v1/pods'
kubectl proxy --www=/my/files --www-prefix=/static/ --api-prefix=/api/
# To proxy the entire Kubernetes API at a different root
# You can get pods info with 'curl localhost:8001/custom/api/v1/pods'
kubectl proxy --api-prefix=/custom/
# Run a proxy to the Kubernetes API server on port 8011, serving static content from ./local/www/
kubectl proxy --port=8011 --www=./local/www/
# Run a proxy to the Kubernetes API server on an arbitrary local port
# The chosen port for the server will be output to stdout
kubectl proxy --port=0
# Run a proxy to the Kubernetes API server, changing the API prefix to k8s-api
# This makes e.g. the pods API available at localhost:8001/k8s-api/v1/pods/
kubectl proxy --api-prefix=/k8s-api

38 - kubectl scale
Synopsis
Set a new size for a deployment, replica set, replication controller, or stateful set.
Scale also allows users to specify one or more preconditions for the scale action.
If --current-replicas or --resource-version is specified, it is validated before the scale is attempted, and it is guaranteed that the precondition holds true when the scale is sent to the server.
kubectl scale [--resource-version=version] [--current-replicas=count] --replicas=COUNT (-f FILENAME | TYPE NAME)
Examples
# Scale a replica set named 'foo' to 3
kubectl scale --replicas=3 rs/foo
# Scale a resource identified by type and name specified in "foo.yaml" to 3
kubectl scale --replicas=3 -f foo.yaml
# If the deployment named mysql's current size is 2, scale mysql to 3
kubectl scale --current-replicas=2 --replicas=3 deployment/mysql
# Scale multiple replication controllers
kubectl scale --replicas=5 rc/example1 rc/example2 rc/example3
# Scale stateful set named 'web' to 3
kubectl scale --replicas=3 statefulset/web

40 - kubectl taint
Synopsis
Update the taints on one or more nodes.
- A taint consists of a key, value, and effect. As an argument here, it is expressed as key=value:effect.
- The key must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 253 characters.
- Optionally, the key can begin with a DNS subdomain prefix and a single '/', like example.com/my-app.
- The value is optional. If given, it must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 63 characters.
- The effect must be NoSchedule, PreferNoSchedule or NoExecute.
- Currently taint can only apply to node.

# Update node 'foo' with a taint with key 'dedicated' and value 'special-user' and effect 'NoSchedule'
# If a taint with that key and effect already exists, its value is replaced as specified
kubectl taint nodes foo dedicated=special-user:NoSchedule
# Remove from node 'foo' the taint with key 'dedicated' and effect 'NoSchedule' if one exists
kubectl taint nodes foo dedicated:NoSchedule-
# Remove from node 'foo' all the taints with key 'dedicated'

44 - kubectl wait
Synopsis
Experimental: Wait for a specific condition on one or many resources.
The command takes multiple resources and waits until the specified condition is seen in the Status field of every given resource.
Alternatively, the command can wait for the given set of resources to be deleted by providing the "delete" keyword as the value to the --for flag.
A successful message will be printed to stdout indicating when the specified condition has been met. You can use -o option to change to output destination.
kubectl wait ([-f FILENAME] | resource.group/resource.name | resource.group [(-l label | --all)]) [--for=delete|--for condition=available|--for=jsonpath='{}'[=value]]
Examples
# Wait for the pod "busybox1" to contain the status condition of type "Ready"
kubectl wait --for=condition=Ready pod/busybox1
# The default value of status condition is true; you can wait for other targets after an equal delimiter (compared after Unicode simple case folding, which is a more general form of case-insensitivity)
kubectl wait --for=condition=Ready=false pod/busybox1
# Wait for the pod "busybox1" to contain the status phase to be "Running"
kubectl wait --for=jsonpath='{.status.phase}'=Running pod/busybox1
# Wait for pod "busybox1" to be Ready
kubectl wait --for='jsonpath={.status.conditions[?(@.type=="Ready")].status}=True' pod/busybox1
# Wait for the service "loadbalancer" to have ingress
