So, when trying to install a logstash plugin inside a docker container (using an interactive shell, or a Dockerfile or docker-compose , doesn't matter), this happens:
sh-4.2$ ./logstash-plugin install logstash-codec-sflow ERROR: Something went wrong when installing logstash-codec-sflow, message: execution expired
It seems there is no verbose option for the plugin installer, so I have to idea what to look for.
Also, the docker container has working internet. Any ideas?
