Detailed explanation on how to get the IP address of a docker container

1. After entering the container

cat /etc/hosts

It will show the IP address of the container itself and the (- link) soft link.

2. Use commands

docker inspect --format '{{ .NetworkSettings.IPAddress }}' <container-ID>

or

docker inspect <container id>

or

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_name_or_id

3. Consider writing a bash function in ~/.bashrc:

function docker_ip() {
 sudo docker inspect --format '{{ .NetworkSettings.IPAddress }}' $1
}

source ~/.bashrc and then:

$ docker_ip <container-ID>

172.17.0.6

4. To get all container names and their IP addresses just one command is needed.

docker inspect -f '{{.Name}} - {{.NetworkSettings.IPAddress }}' $(docker ps -aq)

If you use docker-compose the command will be:

docker inspect -f '{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq)

5. Display all container IP addresses:

docker inspect --format='{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq)
