Hopefully you are now starting to see use cases for different types of plugins.For example, a developer is fine working with local volumes, however for production traffic you would want to have some sort of either shared or block storage which is accessible to containers across multiple Docker hosts.

With plugins, this is possible without any real changes to your user's workflow as you know exactly how Docker handles volumes created with the docker volume create command.

As already mentioned, Docker are in the process of transitioning legacy plugins to a new architecture, a list of legacy plugins can be found at the following URL https://docs.docker.com/engine/extend/legacy_plugins/ and new plugins which use the new architecture a can be found at https://store.docker.com/search?q=&type=plugin.

In the next chapter, we are going to look at how to monitor your containers, and what to do if anything goes wrong.
