I am using the base docker image from Logstash 7.6.0. It is a cenOS image.  
I am trying to install a custom java filter plugin.  
I used the example "java filter" in the Logstash to build from there.

I built my gem on the same docker image, and Gradle was able to get its dependencies, after I added my company root CA cert the the JVM trustcacert store. So I know, that acces to public websites / repos should work.

When trying to install the "gem" plugin (locally) I get an error, even if I have the " --no-verify" option enabled.

`/usr/share/logstash/bin/logstash-plugin install --local --no-verify /opt/my_java_plugin/logstash-filter-java_filter_example-1.0.0.gem`

`ERROR: Something went wrong when installing /opt/my_java_plugin/logstash-filter-java_filter_example-1.0.0.gem, message: certificate verify failed`

Is there any way to get debug info on this "plugin intall" command"?

Probably the same issue as :

> [@Plugin install failed even with 'no-verify'](https://discuss.elastic.co/t/plugin-install-failed-even-with-no-verify/99869):

> Not sure if I got the syntax right, but # bin/logstash-plugin install logstash-filter-tld ERROR: Something went wrong when installing logstash-filter-tld, message: certificate verify failed # bin/logstash-plugin install --no-verify logstash-filter-tld ERROR: Something went wrong when installing logstash-filter-tld, message: certificate verify failed Suggestions? If I have to request some sort of firewall exception, is it only to [artifacts.elastic.co](http://artifacts.elastic.co) or do I need to include other domains? A…
