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.
Examples
Roll back to the previous version of a service
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
