How To Change The Default Docker Engine Ip

1. Inspect system IP and docker network. Use sudo if you are getting permission denied error, ex: sudo docker network list

   ip a
   docker network list
   # docker network inspect etc_default | grep Subnet
   docker network inspect bridge

2. Create file /etc/docker/daemon.json if it does not already exits

   sudo vi /etc/docker/daemon.json

   • Provide the required IP details and following details

     {
       "live-restore": true,
       "bip": "172.17.0.1/24",
       "default-address-pools": [{
         "base": "172.17.0.1/24",
         "size": 24
       }]
     }

3. CAUTION: DO NOT run this if you are not sure what it does Cleanup existing container, images and network. Skip this step, and run this only if things are not working;

   ## Delete all running docker containers:
   docker rm -f `docker ps -q -a`
   ## Delete all unused Docker objects:
   docker system prune
   docker network prune

4. Restart docker service

   sudo systemctl restart docker
