### 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:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ docker service create --name my-service -p 8080:80 nginx:alpine
|
||
|
|
```
|
||
|
|
|
||
|
|
Confirm that the service is running with a single replica:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ 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:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ 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:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ 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
|
||
|
|
```
