This is a ragged version of flannel (vxlan backend). It's also a demo of how to use duck-etcd.
Although it's "ragged", but it does implement the basic list & wach. It will maintain/update the flannel rules when node is added or deleted.
Please install make and vagrant first.
There are 4 VMs defined in the Vagrantfile.
The node name and corresponding IP addresses are as follows:
| node name | host ip | pod subnet |
|---|---|---|
| etcd | 192.168.56.60 | |
| node1 | 192.168.56.61 | 10.244.1.0/24 |
| node2 | 192.168.56.62 | 10.244.2.0/24 |
| node3 | 192.168.56.63 | 10.244.3.0/24 |
