其中,Flags主要为日志选项。

token

token子命令用于获取用户token,获取token的认证方式有用户名/密码、ak/sk两种,选择其中一种即可。

      --sk string                  IAM secret access key
      --token-expired-refresh      Whether refresh the cached token when it may have expired resulting unauthorized. If true, we will use client.authentication.k8s.io/v1alpha1 api version. Otherwise, use client.authentication.k8s.io/v1beta1
      --token-only                 Return token only for other tool integration
      --user-name string           IAM user name. Same as domain-name when using main account, otherwise use iam user name

cache

CREDENTIAL_CACHE

是否开启将IAM Token缓存到本地,提高访问性能,默认为true。

注意:

在非安全环境,建议关闭此选项。

generate-kubeconfig

为用户直接生成KubeConfig配置,若指定的KubeConfig已存在,则会注入新的server、user、context配置,并将当前的KubeConfig context切换到此次配置的结果。

Generate or modify kubeconfig files based on user configuration.

Sets a cluster entry, a user entry and a context entry in kubeconfig and use this context as the current-context.

  The loading order follows these rules:
	 
   1.  If the --kubeconfig flag is set, then only that file is loaded. The flag may only be set once and no merging takes
place.
   2.  If $KUBECONFIG environment variable is set, then it is used as a list of paths (normal path delimiting rules for
your system). These paths are merged. When a value is modified, it is modified in the file that defines the stanza. When
a value is created, it is created in the first file that exists. If no files in the chain exist, then it creates the
last file in the list.
   3.  Otherwise, ${HOME}/.kube/config is used and no merging takes place.

 Examples:
   # Generate kubeconfig to ${HOME}/.kube/config using aksk
   asm-iam-authenticator generate-kubeconfig --mesh-endpoint=https://127.0.0.1:5443 --ak=*** --sk=***
   # Generate kubeconfig to ${HOME}/.kube/config using domain name and password
   asm-iam-authenticator generate-kubeconfig --mesh-endpoint=https://127.0.0.1:5443 --domain-name=*** --password=***

Usage:
  asm-iam-authenticator generate-kubeconfig [flags]

      --aksk-dir string            The directory of IAM access key(AK) and secret access key(SK)
      --cache                      Cache the token credential on disk until it expires (default true)
      --domain-name string         IAM domain name, typically your account name
  -h, --help                       help for generate-kubeconfig
      --iam-endpoint string        HuaweiCloud IAM endpoint, i.e. https://iam.cn-north-4.myhuaweicloud.com (default "https://iam.myhuaweicloud.com")
