To set custome IP address range to your container in docker

sudo vim /etc/default/docker
add this line to file

DOCKER_OPTS="--bip=10.66.33.10/24"
then reboot
after reboot start a container

docker run -it --name t2 jangorecki/r-base-dev /bin/bash
and check ip of a container

docker inspect --format '{{ .NetworkSettings.IPAddress }}' t2


OR

docker exec -it c1 bash -c "echo -e 'IPADDR=172.17.0.4 \n HOSTNAME=c1' >> /etc/sysconfig/network-scripts/ifcfg-eth0; /etc/init.d/network restart";


OR - to change the IP address of this docker container

You will have to first detach the container from the custom network and the connect it back by providing the ip.

You can follow the following steps :

docker network disconnect [OPTIONS] NETWORK CONTAINER
docker network connect --ip 192.168.150.3 NETWORK CONTAINER


docker network ls
   20  docker run -d --name myn1 nginx
   21  docker ps -a
   22  docker inspect myn1
   23  clear
   24  docker network create --driver bridge edureka1
   25  docker network ls
   26  docker network create --driver bridge edureka2
   27  docker network ls
   28  clear
   29  docker run -itd --name b1 --network edureka1 busybox
   30  docker inspect b1
   31  clear
   32  docker run -itd --name b2 --network edureka1 busybox
   33  docker inspect b2
   34  clear
   35  docker attach b1
   36  docker run -itd --name b3 --network edureka2 busybox
   37  docker inspect b3
   38  clear
   39  docker attach b3
   40  docker attach b2
   41  docker network connect edureka2 b2
   42  docker inspect b2
   43  clear
   44  docker attach b2
