Another tool worth looking at is vpncloud (https://github.com/dswd/vpncloud https://github.com/dswd/vpncloud). I used to use tinc, but switched to vpncloud 2 years ago. In my use case, I have a modest number of nodes. Although nodes learn of other nodes from each other, I use ansible to keep each node's config updated. I use vpncloud (and previously, tinc) between docker hosts. So, you have to be careful about interface MTU's inside of docker, particularly if you use containers based on Alpine.
