Usage: vault login -method=alicloud [CONFIG K=V...]
The AliCloud auth method allows users to authenticate with AliCloud RAM
credentials.
The AliCloud RAM credentials may be specified explicitly via the command line:
$ vault login -method=alicloud access_key=... secret_key=... security_token=... region=...
Configuration:
access_key=<string>
Explicit AliCloud access key ID
secret_key=<string>
Explicit AliCloud secret access key
security_token=<string>
Explicit AliCloud security token
region=<string>
Explicit AliCloud region
mount=<string>
Path where the AliCloud credential method is mounted. This is usually provided
via the -path flag in the "vault login" command, but it can be specified
here as well. If specified here, it takes precedence over the value for
-path. The default value is "alicloud".
role=<string>
Name of the role to request a token against
