vxlan

Very simple overlay network provider designed as docker container.

Usage

docker run -d \
  --net=host \
  --privileged=true \
  --restart=always \
  -e VIP=192.168.10.1/24 \
  -e VNI=10 \
  -e IF=eth1 \
  -e "HOSTS=123.45.67.89,123.45.67.90" \
  s21g/vxlan

• The container will add vxlan10 interface linked with eth1
• and add routes to HOSTS (comma separated global IPs)

And you need to

• run containers for each hosts varying VIP (ex "192.168.10.2", ...)
• make UDP port 8472 accessible between each hosts

Environment variables:

• VIP: mandatory parameter <ip>/<prefix>[,<ip>/<prefix>,...]
• VNI='10'
• VXLAN="vxlan$VNI"
• IF="eth0"
• MTU="1440"
• HOSTS=""
• PORT=${PORT:="0"}: 0 means to use default port 8472/udp
