command: docker service update
short: Update a service
long: |-
  Updates a service as described by the specified parameters. The parameters are
  the same as [`docker service create`](service_create.md). Refer to the description
  there for further information.

  Normally, updating a service will only cause the service's tasks to be replaced with new ones if a change to the
  service requires recreating the tasks for it to take effect. For example, only changing the
  `--update-parallelism` setting will not recreate the tasks, because the individual tasks are not affected by this
  setting. However, the `--force` flag will cause the tasks to be recreated anyway. This can be used to perform a
  rolling restart without any changes to the service parameters.

examples: |-
  ### Update a service

  ```bash
  $ docker service update --limit-cpu 2 redis
  ```

  ### Perform a rolling restart with no parameter changes

  ```bash
  $ docker service update --force --update-parallelism 1 --update-delay 30s redis
  ```

  In this example, the `--force` flag causes the service's tasks to be shut down
  and replaced with new ones even though none of the other parameters would
  normally cause that to happen. The `--update-parallelism 1` setting ensures
  that only one task is replaced at a time (this is the default behavior). The
  `--update-delay 30s` setting introduces a 30 second delay between tasks, so
  that the rolling restart happens gradually.

  ### Add or remove mounts

  Use the `--mount-add` or `--mount-rm` options add or remove a service's bind mounts
  or volumes.

  The following example creates a service which mounts the `test-data` volume to
  `/somewhere`. The next step updates the service to also mount the `other-volume`
  volume to `/somewhere-else`volume, The last step unmounts the `/somewhere` mount
  point, effectively removing the `test-data` volume. Each command returns the
  service name.

  - The `--mount-add` flag takes the same parameters as the `--mount` flag on
    `service create`. Refer to the [volumes and bind mounts](service_create.md#add-bind-mounts-volumes-or-memory-filesystems)
    section in the `service create` reference for details.

  - The `--mount-rm` flag takes the `target` path of the mount.

  ```bash
  $ docker service create \
      --name=myservice \
      --mount type=volume,source=test-data,target=/somewhere \
      nginx:alpine

  myservice

  $ docker service update \
      --mount-add type=volume,source=other-volume,target=/somewhere-else \
      myservice

  myservice

  $ docker service update --mount-rm /somewhere myservice

  myservice
  ```

  ### Add or remove published service ports

  Use the `--publish-add` or `--publish-rm` flags to add or remove a published
  port for a service. You can use the short or long syntax discussed in the
  [docker service create](service_create.md#publish-service-ports-externally-to-the-swarm--p---publish)
  reference.

  The following example adds a published service port to an existing service.

  ```bash
  $ docker service update \
    --publish-add published=8080,target=80 \
    myservice
  ```

  ### Add or remove network

  Use the `--network-add` or `--network-rm` flags to add or remove a network for
  a service. You can use the short or long syntax discussed in the
  [docker service create](service_create.md#attach-a-service-to-an-existing-network---network)
  reference.

  The following example adds a new alias name to an existing service already connected to network my-network:

  ```bash
  $ docker service update \
    --network-rm my-network \
    --network-add name=my-network,alias=web1 \
    myservice
  ```

  ### Roll back to the previous version of a service

  Use the `--rollback` option to roll back to the previous version of the service.

  This will revert the service to the configuration that was in place before the most recent `docker service update` command.

  The following example updates the number of replicas for the service from 4 to 5, and then rolls back to the previous configuration.

  ```bash
  $ docker service update --replicas=5 web

  web

  $ docker service ls

  ID            NAME  MODE        REPLICAS  IMAGE
  80bvrzp6vxf3  web   replicated  0/5       nginx:alpine

  ```
  Roll back the `web` service...

  ```bash
  $ docker service update --rollback web

  web

  $ docker service ls

  ID            NAME  MODE        REPLICAS  IMAGE
  80bvrzp6vxf3  web   replicated  0/4       nginx:alpine

  ```

  Other options can be combined with `--rollback` as well, for example, `--update-delay 0s` to execute the rollback without a delay between tasks:

  ```bash
  $ docker service update \
    --rollback \
    --update-delay 0s
    web

  web

  ```

  Services can also be set up to roll back to the previous version automatically
  when an update fails. To set up a service for automatic rollback, use
  `--update-failure-action=rollback`. A rollback will be triggered if the fraction
  of the tasks which failed to update successfully exceeds the value given with
  `--update-max-failure-ratio`.

  The rate, parallelism, and other parameters of a rollback operation are
  determined by the values passed with the following flags:

  - `--rollback-delay`
  - `--rollback-failure-action`
  - `--rollback-max-failure-ratio`
  - `--rollback-monitor`
  - `--rollback-parallelism`

  For example, a service set up with `--update-parallelism 1 --rollback-parallelism 3`
  will update one task at a time during a normal update, but during a rollback, 3
  tasks at a time will get rolled back. These rollback parameters are respected both
  during automatic rollbacks and for rollbacks initiated manually using `--rollback`.

  ### Add or remove secrets

  Use the `--secret-add` or `--secret-rm` options add or remove a service's
  secrets.

  The following example adds a secret named `ssh-2` and removes `ssh-1`:

  ```bash
  $ docker service update \
      --secret-add source=ssh-2,target=ssh-2 \
      --secret-rm ssh-1 \
      myservice
  ```

  ### Update services using templates

  Some flags of `service update` support the use of templating.
  See [`service create`](service_create.md#create-services-using-templates) for the reference.


  ### Specify isolation mode (Windows)

  `service update` supports the same `--isolation` flag as `service create`
  See [`service create`](service_create.md) for the reference.
