[lxc-users] How to set the resource limits to a container

[Guido Jäkel]

Dear Andy,

This will "put pressure on the memory". If something can be given free (like the file cache), it will. Then, if it's still over the limit, either the Linux OOM thread will kill processses. Or the container will freeze, if you configure it with memory.oom_control = 1

RFTM at https://www.kernel.org/doc/Documentation/cgroups/memory.txt ;)

greetings

Guido
