Revert changes to a service's configuration
| Name | Type | Default | Description |
|---|---|---|---|
-d, --detach | Exit immediately instead of waiting for the service to converge | ||
-q, --quiet | Suppress progress output |
Roll back a specified service to its previous version from the swarm.
Note
This is a cluster management command, and must be executed on a swarm manager node. To learn about managers and workers, refer to the Swarm mode section in the documentation.
Use the docker service rollback command to roll back to the previous version of a service. After executing this command, the service is reverted to the configuration that was in place before the most recent docker service update command.
The following example creates a service with a single replica, updates the service to use three replicas, and then rolls back the service to the previous version, having one replica.
Create a service with a single replica:
$ docker service create --name my-service -p 8080:80 nginx:alpine
Confirm that the service is running with a single replica:
$ docker service ls ID NAME MODE REPLICAS IMAGE PORTS xbw728mf6q0d my-service replicated 1/1 nginx:alpine *:8080->80/tcp
Update the service to use three replicas:
$ docker service update --replicas=3 my-service $ docker service ls ID NAME MODE REPLICAS IMAGE PORTS xbw728mf6q0d my-service replicated 3/3 nginx:alpine *:8080->80/tcp
Now roll back the service to its previous version, and confirm it is running a single replica again:
$ docker service rollback my-service $ docker service ls ID NAME MODE REPLICAS IMAGE PORTS xbw728mf6q0d my-service replicated 1/1 nginx:alpine *:8080->80/tcp
