Add support for mounting additional plugins #133

Closed bernd closed 3 years ago

bernd commented 3 years ago

Since Graylog 4.0 requires the new storage plugins to be present to start up correctly, we should introduce a mount point for adding additional plugins to the image.

Something like -v /path/to/my/plugins:/plugins or similar. The docker-entrypoint.sh script takes all plugins in /plugins and merges them with the default plugins we ship into a directory like /plugins-merged. The /plugins-merged would be the default plugin_dir in the container. Before merging the plugins we need to remove all plugins in /plugins-merged on startup to make sure there are no old plugins present.

This could be a workaround until https://github.com/Graylog2/graylog2-server/issues/6482 is implemented.

@bernd Once plugins/ is mounted, everything that was in the directory before is gone (as far as the container is concerned). I think to do this, we'd need a third directory to store the default plugins, such as /plugins-default.

@juju2112 Yeah, agreed. That's what I tried to explain in the description. :smile:
