How to display IP Address for the “devopsroles” container as below:
$ sudo docker inspect -f '{{ .NetworkSettings.IPAddress }}' devopsroles
The output below:
172.17.0.2
For example, display IP, Image, Name, Host Config, status for containers as below:
$ sudo docker inspect -f 'Image:[{{ .Config.Image}}] Name:{{.Name}} HostConfig:{{ .HostConfig.Binds}} Status:{{ .State.Status}} IP_Container:{{ .NetworkSettings.IPAddress }} ' 055772699b49 | cat -n
The output below:
1 Image:[devopsroles/nginx:v2] Name:/devopsroles HostConfig:[/home/huupv/project/nginx/devopsroles:/var/www/html/devopsroles:ro] Status:running IP_Container:172.17.0.2
Another method as below:
$ sudo docker inspect -f 'Image:[{{ .Config.Image}}] Name:{{.Name}} HostConfig:{{ .HostConfig.Binds}} Status:{{ .State.Status}} IP_Container:{{ .NetworkSettings.IPAddress }} ' $(sudo docker ps -a -q) | cat -n
How to display all containers, including non-running
$ sudo docker ps -a -q
The output below:
