The only guaranteed way to have 2 containers running on the same node is when you run then as sidecar. Means 1 pod 2 containers.  
But i’ve not tried sharing memory between them.  
My hunch is, it may not be possible because of cgroups.

This [Fast IPC between multiple pods on same node](https://discuss.kubernetes.io/t/fast-ipc-between-multiple-pods-on-same-node/9594/5) looks related.
