Hello @pavfdev and welcome to this community 
I know the question is not for me, but I’ve heard numerous times that the good practice was to start from the official inbound-agent, docker-agent, or ssh-agent images and to extend them to add your needed tools/packages.
I know some specific (i.e. python) “official” images exist, but they are not really maintained (even if published regularly).
The python one for example, has some parts of the inbound-agent, and some parts of the official python image, but misses essential parts of the two base images (like git for example).
