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
