pod: description: - The pod name required: true type: str host: description: - Provide a URL for accessing the API. Can also be specified via K8S_AUTH_HOST environment variable. type: str proxy: description: - The URL of an HTTP proxy to use for the connection. - Can also be specified via I(K8S_AUTH_PROXY) environment variable. - Please note that this module does not pick up typical proxy settings from the environment (e.g. HTTP_PROXY). type: str api_key: description: - Token used to authenticate with the API. Can also be specified via K8S_AUTH_API_KEY environment variable. type: str ca_cert: aliases: - ssl_ca_cert description: - Path to a CA certificate used to authenticate with the API. The full certificate chain must be provided to avoid certificate validation errors. Can also be specified via K8S_AUTH_SSL_CA_CERT environment variable. type: path command: description: - The command to execute required: true type: str context: description: - The name of a context found in the config file. Can also be specified via K8S_AUTH_CONTEXT environment variable. type: str password: description: - Provide a password for authenticating with the API. Can also be specified via K8S_AUTH_PASSWORD environment variable. - Please read the description of the C(username) option for a discussion of when this option is applicable. type: str username: description: - Provide a username for authenticating with the API. Can also be specified via K8S_AUTH_USERNAME environment variable. - Please note that this only works with clusters configured to use HTTP Basic Auth. If your cluster has a different form of authentication (e.g. OAuth2 in OpenShift), this option will not work as expected and you should look into the C(k8s_auth) module, as that might do what you need. type: str container: description: - The name of the container in the pod to connect to. - Defaults to only container if there is only one container in the pod. required: false type: str namespace: description: - The pod namespace name required: true type: str client_key: aliases: - key_file description: - Path to a key file used to authenticate with the API. Can also be specified via K8S_AUTH_KEY_FILE environment variable. type: path kubeconfig: description: - Path to an existing Kubernetes config file. If not provided, and no other connection options are provided, the openshift client will attempt to load the default configuration file from I(~/.kube/config.json). Can also be specified via K8S_AUTH_KUBECONFIG environment variable. type: path client_cert: aliases: - cert_file description: - Path to a certificate used to authenticate with the API. Can also be specified via K8S_AUTH_CERT_FILE environment variable. type: path persist_config: description: - Whether or not to save the kube config refresh tokens. Can also be specified via K8S_AUTH_PERSIST_CONFIG environment variable. - When the k8s context is using a user credentials with refresh tokens (like oidc or gke/gcloud auth), the token is refreshed by the k8s python client library but not saved by default. So the old refresh token can expire and the next auth might fail. Setting this flag to true will tell the k8s python client to save the new refresh token to the kube config file. - Default to false. - Please note that the current version of the k8s python client library does not support setting this flag to True yet. - 'The fix for this k8s python library is here: https://github.com/kubernetes-client/python-base/pull/169' type: bool validate_certs: aliases: - verify_ssl description: - Whether or not to verify the API server's SSL certificates. Can also be specified via K8S_AUTH_VERIFY_SSL environment variable. type: bool
