Secure docker instances

I've a problem with the servers I'm setting up on digitalocean.

All these servers are hacked(All my databases are emptied and pwned) after 2-3 days.

I'm running docker images in all of them and I'm suspicious that the problem is related I'm running docker.

I've been digging into how to secure docker instances, but I don't quite to figure out which're the best practices to really secure my docker instances.

Could you provide me some straightforward practices to secure them a bit more?

  1. What about control groups (CGroups)?
  2. What does kernel namespaces stand for?
  3. Is there any seccomp profiles repository?
