Get image information
Use the docker inspect image command to obtain information about images.
haicoder(www.haicoder.net)# docker inspect ubuntu
After running, the terminal displays information as shown in the figure below:
Get container information
Use the docker run -it -d command to start a dokcer container.
haicoder(www.haicoder.net)# docker run -it --name haicoder -d ubuntu

Use the docker inspect container command to obtain information about containers.
haicoder(www.haicoder.net)# docker inspect haicoder
After running, the terminal displays information as shown in the figure below:
Use **docker kill** and docker rm commands to remove all containers.
haicoder(www.haicoder.net)# docker kill `docker ps -qa` ; docker rm `docker ps -aq`
Get container name
Use the docker run -it -d command to start a dokcer container.
haicoder(www.haicoder.net)# docker run -it --name haicoder -d ubuntu
#输出

Use the docker inspect container -f { {.Name}} command to get the container name.
haicoder(www.haicoder.net)# docker inspect haicoder -f {
{.Name}}
#输出
/haicoder
After running, the terminal outputs the container name information. Finally, we use the docker kill and docker rm commands to remove all containers.
haicoder(www.haicoder.net)# docker kill `docker ps -qa` ; docker rm `docker ps -aq`
Get container network settings information
Use the docker run -it -d command to start a dokcer container.
haicoder(www.haicoder.net)# docker run -it --name haicoder -d ubuntu

Use the docker inspect CONTAINER -f { {.NetworkSettings}} command to get information about container network settings.
haicoder(www.haicoder.net)# docker inspect -f {
{.NetworkSettings}} haicoder
#输出

After running, the terminal outputs information about the network settings of the container. Finally, we use the docker kill and docker rm commands to remove all containers.
haicoder(www.haicoder.net)# docker kill `docker ps -qa` ; docker rm `docker ps -aq`
Get container IP information
Use the docker run -it -d command to start a dokcer container.
haicoder(www.haicoder.net)# docker run -it --name haicoder -d ubuntu
ec342264b9debef5ac8a885f1479e8f3b9ef1c60bc70231063c849bcc930deac
Use the docker inspect container -f { {.NetworkSettings.IPAddress}} command to obtain information about the IP address of the container.
haicoder(www.haicoder.net)# docker inspect -f {
{.NetworkSettings.IPAddress}} haicoder
#输出
172.17.0.2
After running, the terminal outputs the IP information of the container. Finally, we use the docker kill and docker rm commands to remove all containers.
haicoder(www.haicoder.net)# docker kill `docker ps -qa` ; docker rm `docker ps -aq`
