Usage: vault login -method=github [CONFIG K=V...]
|
|
|
|
The GitHub auth method allows users to authenticate using a GitHub
|
|
personal access token. Users can generate a personal access token from the
|
|
settings page on their GitHub account.
|
|
|
|
Authenticate using a GitHub token:
|
|
|
|
$ vault login -method=github token=abcd1234
|
|
|
|
Configuration:
|
|
|
|
mount=<string>
|
|
Path where the GitHub 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 "github".
|
|
|
|
token=<string>
|
|
GitHub personal access token to use for authentication. If not provided,
|
|
Vault will prompt for the value.
