I have a logstash dockerfile which uses the elastic docker 5.3.2 image (docker.elastic.co/logstash/logstash:5.3.2) as a base and installs 3 local gem plugins which aren't in the logstash plugin repository.
If I bump the version to 5.4.0, then any attempt to install a local plugin results in the following error:
which: no javac in (/usr/share/logstash/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin)
I've seen reference to a similar bug report, but not in the context of the pre-built docker images. See here: https://github.com/elastic/logstash/issues/5966
Any help would be appreciated!
