Background: I’m relatively new to Docker, but have extensive *nix experience. In my personal life I’ve run mostly Ubuntu, but lately I’ve been trying to run Fedora or CentOS as we’re 100% RHEL at work and I’m tired of typing “apt-get” when I should be typing “yum”.
So trying to get Discourse running on Fedora per the Install guide has been… enlightening. Every thread I read, all of my googling, pointed to AUFS as being the only workable solution. Not a huge deal, I’ve been recompiling kernels for twenty years. But since it seems AUFS is never going to be merged, it’s certainly not ideal.
I guess my question is, is there a strong reason to use AUFS over OverlayFS? Overlay has been merged since 3.18 (and backported to RHEL7), Docker supports it now (on EXT4). Sure, SELinux has issues, but those are going to be solved eventually. And now I’m not limited to Ubuntu for an out-of-the-box Discourse install, which is fantastic because I’ve been wanting to use it at work.
I have Discourse bootstrapped on Fedora without error and everything appears to be running great… but are there known issues that could bite me down the road?
