I mentioned Docker because it interests many developers but on VMs that I control I do not need Docker at all. Deploying with Docker provides host OS independence which is nice if you are distributing but unnecessary if the host is yours, running a fixed OS.

For Python backends I often deploy the code directly with a Puppet resource called VcsRepo which basically places a certain tag of a certain repo on a certain filesystem location. And I also package the systemd scripts for easy start/stop/restart. You can do this with other config management tools, via bash or by hand, depending on how many systems you manage.

What bothers me with your question is Pip :-) But perhaps that is off topic...?

No, you are tied to docker supported operating systems.

Will not run on FreeBSD, for example.

I'll correct myself:

s/host OS independence/a certain level of host OS independence

And getting containers to run depends on the OS - if you don't control the host, leads to major ping-pongs.

Even within Linux (Ubuntu, Debian, RHEL, etc) when you are distributing multiple related containers there are details to care about, not about the container itself but about the base OS configuration. It's not magic.

Not true:

Yes, so not really supported.

[BSDobelix]

That's the lamest excuse ever, are you a tech guy or a lawyer?

[dlisboa]

OP is talking about substituting a Kubernetes setup. FreeBSD was never in the cards. 99% of companies in the cloud don’t run or care about anything other than Linux.

[Gud]

That may be true, but it’s still not “host OS independence”, which was my point

No, you're tied to operating systems using a Linux kernel that supports the features necessary for running images.

[Gud]

You can run Linux under FreeBSD using either bhyve, using the Linux emulator and under jails. But you cannot run docker.

You can -> Podmaaan
