A service 'wordpress' is running using a password string to connect to a non-Dockerized database service. The password string is passed into the 'wordpress' service as a Docker secret. Per security policy, the password on the database was changed. Identity the correct sequence of steps to rotate the secret from the old password to the new password.

  1. Create a new docker secret with the new password. Trigger a rolling secret update by using the 'docker secret update' command
  2. Trigger an update to the service by using 'docker service update --secret=<new password>'
  3. Create a new docker secret with the new password. Remove the existing service using 'docker service rm'. Start anew service with the new secret using "--secret=<new password>"
  4. Create a new docker secret with a new password. Trigger a rolling update of the "wordpress" service, by using "--secret-rm" &"--secret-add" to remove the old secret and add the updated secret.

Answer(s): D
