# Docker Swarm Snippets and Musings

## Updating Services

View services:

```bash
docker service ls
```

To scale a service up or down:

```bash
docker service scale <service_name>=<number_of_replicas>
```

Sometimes services get stuck or need to be forcefully updated:

```bash
docker service update --force <service_name>
```

::: tip

Sometimes if you need to force containers to restart use the update force (e.g. after restarting a node).
