Hi there
We've just finished provisioning a new Galaxy server here using the ansible-galaxy and ansible-galaxy-extras roles, with some extra roles from Nate and our own creation. In the ansible-galaxy role Galaxy's install location is set using the galaxy_server_dir variable, but in ansible-galaxy-extras the variables galaxy_home_dir and galaxy_root (presumably for distinct locations for the galaxy user's home directory and the root of the Galaxy installation) are used.
Is this difference deliberate? Attached is our Ansible playbook - we just configured the variables to all point to the same location (and set the galaxy_venv_dir to be .venv not venv). I thought the two roles were meant to work together, so this difference is somewhat confusing.
Thanks, Peter
Peter - thanks for sharing this.
ansible-galaxy-extras and ansible-galaxy were just created by different people at different times and I don't think a lot of thought went into rationalizing variable names across projects. Indeed even within ansible-galaxy-extras the variable names aren't very consistent. I have opened a PR to switch ansible-galaxy-extras over to using galaxy_server_dir - because ansible-galaxy is clearly the more reasonable thought out role and has been published to the ... unfortunately named... Anisble Galaxy (https://galaxy.ansible.com/).
https://github.com/galaxyproject/ansible-galaxy-extras/pull/48
Some other people have brought up this problem as well, I'm happy to make changes needed to ansible-galaxy-extras to bring it in line with the rest of Galaxy ansible ecosystem. As everyone encounters these problems, I'd just encourage opening PRs to adjust them or seeking advice on the issue tracker of any of the projects or here. It would be really nice to have a coherent set of ansible modules.
There is some more discussion on this topic on the following Github issue:
https://github.com/bgruening/docker-galaxy-stable/issues/135
Finally, just a note of warning about ansible-galaxy-extras - it was explicitly created with the intention of one-time provisioning of VMs and Docker images - I didn't put a lot of thought into long running production servers. I don't know of any problems you will encounter - but I did want to give you the buyer beware warning. Since ansible doesn't provide any ability to write tests, I'm pretty sure I'd universally encourage people not to use it as a long running configuration management technology - but obviously I don't speak for the project on that topic since it is used extensively to power Galaxy infrastructure.
Hope this helps and thanks a ton for the contributions, they look awesome!

Well we used ansible-galaxy-extras for provisioning a VM server so - I guess that's just right. I'll have to look into how to script updates - we're trying to move away from "precious" servers to entirely scripted ones. Hopefully put together some PRs to harmonise things.
This stuff would make a good topic for Galaxy-Admins in the future.
