Specific API versions can be turned on or off by passing `--runtime-config=api/<version>` as a
command line argument to the API server. The values for this argument are a comma-separated
list of API versions. Later values override earlier values.

The `runtime-config` command line argument also supports 2 special keys:

- `api/all`, representing all known APIs
- `api/legacy`, representing only legacy APIs. Legacy APIs are any APIs that have been
   explicitly [deprecated](/docs/reference/using-api/deprecation-policy/).

For example, to turn off all API versions except v1, pass `--runtime-config=api/all=false,api/v1=true`
to the `kube-apiserver`.
