Question

A) docker service rollback
B) docker service update --rollback
C) docker service revert
D) docker service down --version

Answer 1

The Docker command to roll back to the previous version of a service is 'docker service update --rollback'. This reverses the service's configuration to the last known good state.

Step-by-step explanation:

The command to roll back to the previous version of a service in Docker is docker service update --rollback. This command reverts the service to the previous version of its configuration, effectively rolling back any changes made since the last service update.

To execute the rollback, you'll need to run this command in your terminal or command prompt where Docker is installed and running. The Docker service will handle the rollback process, ensuring a return to the prior state of the service.
