+## 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).
