[lxc-users] Am I misusing LXCs?

[Scott Lopez]

Is it functioning for you? Yes? Then it isn't wrong. In *nix there are
a dozen ways to skin a cat, and that's before you start scripting in
your language of choice.

Is it the most efficient use? Maybe not. Running a single application
in a LXC container? Maybe you'd be better off with Docker or Rkt. Have
multiple containers to run? Look at CoreOS. Worried about security?
Then maybe separate everything into completely different VMs. Set up
firewalls, vlans and proxies.

So no, you're not misusing LXC. It may not be the best tool for your
job, but your job is running. Be happy!
