options:
- name: attach
default_value: "false"

default_value: "false"
usage: |
If true, a public, external service is created for the container(s) which are run
- name: generator
usage: |
The name of the API generator to use. Default is 'deployment/v1beta1' if --restart=Always, otherwise the default is 'job/v1'. This will happen only for cluster version at least 1.2, for olders we will fallback to 'run/v1' for --restart=Always, 'run-pod/v1' for others.

If the pod is started in interactive mode or with stdin, leave stdin open after the first attach completes. By default, stdin will be closed after the first attach completes.

The resource requirement limits for this container. For example, 'cpu=200m,memory=512Mi'. Note that server side components may assign limits depending on the server configuration, such as limit ranges.

usage: |
Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
- name: overrides
usage: |
An inline JSON override for the generated object. If this is non-empty, it is used to override the generated object. Requires that the object supply a valid apiVersion field.
- name: port
default_value: "-1"
usage: |
The port that this container exposes. If --expose is true, this is also the port used by the service that is created.
- name: record
default_value: "false"

default_value: "1"
usage: |
Number of replicas to create for this container. Default is 1.

The resource requirement requests for this container. For example, 'cpu=100m,memory=256Mi'. Note that server side components may assign requests depending on the server configuration, such as limit ranges.
- name: restart
default_value: Always
usage: |
The restart policy for this Pod. Legal values [Always, OnFailure, Never]. If set to 'Always' a deployment is created for this pod, if set to OnFailure or Never, a job is created for this pod and --replicas must be 1. Default 'Always'

default_value: "false"
usage: |
If true, delete resources created in this command for attached containers.
- name: save-config
default_value: "false"

default_value: service/v2
usage: |
The name of the generator to use for creating a service. Only used if --expose is true
- name: service-overrides
usage: |
