Hi @reimlima,
The docs are useful for non-docker instances, but it seems that I may end up having to re-build the container and add the integrations plugin to the image.
Sorry if I got it wrong, but there’s a topic in the doc which says exactly what you need:
If you want to add plugins, you can put them into a local directory and mount that directory as a volume. This way, you don’t have to create a new docker image every time you want to add a new plugin (or remove an old one).
The example of command even shows how to install this plugin “graylog-integrations-plugins”.
