Usage: vault secrets enable [options] TYPE
|
|
|
|
Enables a secrets engine. By default, secrets engines are enabled at the path
|
|
corresponding to their TYPE, but users can customize the path using the
|
|
-path option.
|
|
|
|
Once enabled, Vault will route all requests which begin with the path to the
|
|
secrets engine.
|
|
|
|
Enable the AWS secrets engine at aws/:
|
|
|
|
$ vault secrets enable aws
|
|
|
|
Enable the SSH secrets engine at ssh-prod/:
|
|
|
|
$ vault secrets enable -path=ssh-prod ssh
|
|
|
|
Enable the database secrets engine with an explicit maximum TTL of 30m:
|
|
|
|
$ vault secrets enable -max-lease-ttl=30m database
|
|
|
|
Enable a custom plugin (after it is registered in the plugin registry):
|
|
|
|
$ vault secrets enable -path=my-secrets -plugin-name=my-plugin plugin
|
|
|
|
OR (preferred way):
|
|
|
|
$ vault secrets enable -path=my-secrets my-plugin
|
|
|
|
For a full list of secrets engines and examples, please see the documentation.
