Just use LXC, that works well on OpenWrt, I'm using that to run various
containers running Debian and OpenWrt on top of OpenWrt.
(but you need to compile it yourself because many of the kernel options
needed for containers aren't enabled by default)

Docker didn't attract a lot of interest because it is x86_64 and
ARM-only, so 80% of OpenWrt-supported devices aren't supported by
Docker which doesn't provide images for MIPS-like CPUs.

However, now that Golang has been added to the packages feed we could
package Docker at least for the platforms supported by it...
