# Assign Pods to Nodes LLMS index: [llms.txt](/llms.txt) --- This page shows how to assign a Kubernetes Pod to a particular node in a Kubernetes cluster. ## Before you begin

You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts. If you do not already have a cluster, you can create one by using minikube or you can use one of these Kubernetes playgrounds:

To check the version, enter kubectl version.

## Add a label to a node 1. List the in your cluster, along with their labels: ```shell kubectl get nodes --show-labels ``` The output is similar to this: ```shell NAME STATUS ROLES AGE VERSION LABELS worker0 Ready 1d v1.13.0 ...,kubernetes.io/hostname=worker0 worker1 Ready 1d v1.13.0 ...,kubernetes.io/hostname=worker1 worker2 Ready 1d v1.13.0 ...,kubernetes.io/hostname=worker2 ``` 1. Choose one of your nodes, and add a label to it: ```shell kubectl label nodes disktype=ssd ``` where `` is the name of your chosen node. 1. Verify that your chosen node has a `disktype=ssd` label: ```shell kubectl get nodes --show-labels ``` The output is similar to this: ```shell NAME STATUS ROLES AGE VERSION LABELS worker0 Ready 1d v1.13.0 ...,disktype=ssd,kubernetes.io/hostname=worker0 worker1 Ready 1d v1.13.0 ...,kubernetes.io/hostname=worker1 worker2 Ready 1d v1.13.0 ...,kubernetes.io/hostname=worker2 ``` In the preceding output, you can see that the `worker0` node has a `disktype=ssd` label. ## Create a pod that gets scheduled to your chosen node This pod configuration file describes a pod that has a node selector, `disktype: ssd`. This means that the pod will get scheduled on a node that has a `disktype=ssd` label.

    pods/pod-nginx.yaml
    
apiVersion: v1
kind: Pod
metadata:
  name: nginx
  labels:
    env: test
spec:
  containers:
  - name: nginx
    image: nginx
    imagePullPolicy: IfNotPresent
  nodeSelector:
    disktype: ssd

1. Use the configuration file to create a pod that will get scheduled on your chosen node: ```shell kubectl apply -f https://k8s.io/examples/pods/pod-nginx.yaml ``` 1. Verify that the pod is running on your chosen node: ```shell kubectl get pods --output=wide ``` The output is similar to this: ```shell NAME READY STATUS RESTARTS AGE IP NODE nginx 1/1 Running 0 13s 10.200.0.4 worker0 ``` ## Create a pod that gets scheduled to specific node You can also schedule a pod to one specific node via setting `nodeName`.

    pods/pod-nginx-specific-node.yaml
    
apiVersion: v1
kind: Pod
metadata:
  name: nginx
spec:
  nodeName: foo-node # schedule pod to specific node
  containers:
  - name: nginx
    image: nginx
    imagePullPolicy: IfNotPresent

Use the configuration file to create a pod that will get scheduled on `foo-node` only. ## What's next * Learn more about [labels and selectors](/docs/concepts/overview/working-with-objects/labels/). * Learn more about [nodes](/docs/concepts/architecture/nodes/).
