Actually, I'm very curious if you have any opinions on combining OSes and some of the tooling that's been coming out (etcd (without CoreOS), and Consul are two examples that come to my mind).

A lot of these container OS's seem to have so much built-in tooling that it seems "wrong" to consider using extra tooling on top of them.

It's a question I've seen pop up every now and then. If you look at the current distribution landscape in any given enterprise today you'll probably see a standardization on one distribution, with a few exceptions here and there. This is mostly due to the need to have ease of management and the same goes for container OSes. If you mix several of them you're adding on "management tax" for the underlying OSes, even if the containers might be managed by a tool on top of it. Deploying/configuring/managing CoreOS is different than RancherOS which is different than SmartOS, for instance.

I say try a few of them, including the tooling that comes with them, and since the containers look the same and will behave the same on all of them you can easily change your underlying OS (and tooling) in this testing phase. Then try the different tools that can be used on top of them and I'm sure you'll find a mix that works for you :)

I like this... it served well to get my feet wet about what is out there. It would be nice having a chart comparing the pro and cons of those OSs. Maybe in the future?

Thanks! :)

Yeah, this seemed more like a listing of the operating systems than a comparison.

You're right, it's a list of the OSes and some of their strengths. I'd rather not get into a container OS war on "which one is better", as I stated at the beginning of the article it always depends on your needs :)

Thank you! I try to list mostly the pros and not the cons, as missing features might pop up in the future which would make the post less useful.

Great Article. Thanks for writing it! :)

Thank you!
