Docker Swarm Snippets and Musings

Updating Services

View services:

docker service ls

To scale a service up or down:

docker service scale <service_name>=<number_of_replicas>

Sometimes services get stuck or need to be forcefully updated:

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).
