I am thinking about deploying logstash as docker container in future in production.
In the past we did not update elastic stack often. In general we hop from major to major version but miss the minor updates. Currently we have classic deployment as systemd service and java is available system wide.
In concern of security we need to update java more often as we update elastic stack.
Whats the best way to keep java for old versions of logstash up to date in docker?
Where can I find the docker file you are using? Then I could just change the java version to fetch build a new image.
Or is there a better / more recommended process? (I am new to docker)
