I didn't want to do it like this, as the containers are not accessible from outside the cluster (they are in separate subnet), and i wanted to avoid nodes acting as routers. A related question is how to set anti-colocation by HW node (so I'll have database master and apps on different nodes if possible)? 2014-02-15 19:40 GMT+01:00 Tomasz Kontusz tomasz.kont...@gmail.com: Hi I'm setting up a cluster which will use OpenVZ containers for separating resource's environments.
