    MasterAuth(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The authentication information for accessing the master
endpoint. Authentication can be done using HTTP basic auth or
using client certificates.

| ## Attributes ||
|---|---|
| **Name** | **Description** |
| `username` | `str` The username to use for HTTP basic authentication to the master endpoint. For clusters v1.6.0 and later, basic authentication can be disabled by leaving username unspecified (or setting it to the empty string). Warning: basic authentication is deprecated, and will be removed in GKE control plane versions 1.19 and newer. For a list of recommended authentication methods, see: https://cloud.google.com/kubernetes-engine/docs/how-to/api-server-authentication |
| `password` | `str` The password to use for HTTP basic authentication to the master endpoint. Because the master endpoint is open to the Internet, you should create a strong password. If a password is provided for cluster creation, username must be non-empty. Warning: basic authentication is deprecated, and will be removed in GKE control plane versions 1.19 and newer. For a list of recommended authentication methods, see: https://cloud.google.com/kubernetes-engine/docs/how-to/api-server-authentication |
| `client_certificate_config` | `https://docs.cloud.google.com/python/docs/reference/container/latest/google.cloud.container_v1.types.ClientCertificateConfig` Configuration for client certificate authentication on the cluster. For clusters before v1.12, if no configuration is specified, a client certificate is issued. |
| `cluster_ca_certificate` | `str` Output only. Base64-encoded public certificate that is the root of trust for the cluster. |
| `client_certificate` | `str` Output only. Base64-encoded public certificate used by clients to authenticate to the cluster endpoint. Issued only if client_certificate_config is set. |
| `client_key` | `str` Output only. Base64-encoded private key used by clients to authenticate to the cluster endpoint. |
