Quick Start

0. Install barrel
1. Create docker network

# driver and ipam-driver name is fixed, don't change them
# subnet should be one cidr address of calico ip-pool
docker network create --ipam-driver calico-ipam --driver calico --subnet 10.1.0.0/16 barrelnet

2. Create fixed ip container and start it, recording its ip

docker run --label fixed-ip --network barrelnet busybox:latest /bin/ash

3. Stop the fixed container and restart it to check whether the ip is changed
4. Remove the container and check whether the ip is released

calicoctl ipam show --ip 10.1.0.1
