Docker cleanup commands
Classification programming technology
Kill all running containers
docker kill $(docker ps -a -q)Delete all stopped containers
docker rm $(docker ps -a -q)Delete all mirrors that are not tagged with dangling
docker rmi $(docker images -q -f dangling=true)Delete the specified mirror by the id of the mirror
docker rmi <image id>Delete all mirrors
docker rmi $(docker images -q)Create aliases for these commands
# ~/.bash_aliases
# 杀死所有正在运行的容器.
alias dockerkill='docker kill $(docker ps -a -q)'
# 删除所有已经停止的容器.
alias dockercleanc='docker rm $(docker ps -a -q)'
# 删除所有未打标签的镜像.
alias dockercleani='docker rmi $(docker images -q -f dangling=true)'
# 删除所有已经停止的容器和未打标签的镜像.
alias dockerclean='dockercleanc || true && dockercleani'

To delete the image in docker, we can use the followingCommand :
docker rmi 镜像id
To delete a container in docker, you can use the following command :
docker rm 容器id
Use the following command to view the currently running container
docker ps
For the exited container, you can use the following command to view:
docker ps -a
For example:
View the currently running containers:
View all images:
View all quitted containers:
Download the image we want to delete "button-api":
At this time, it is found that the deletion fails. According to the prompt information, you can know that the image we want to delete is currently It is used by the container whose id is "a4516aee2e7a", so we must delete the stopped container before deleting the image.
Delete the "button-api" image again after deleting the container:
Now it is found that the deletion is successful.
Re-query all mirrors and find that "button-api" has been deleted:
When deleting, you may also encounter the following situations. If multiple mirror IDs are the same, the deletion will also be unsuccessful:
At this time, we can also delete according to "REPOSITORY" and "TAR":
I now know the difference between deleting a container and deleting an image.
And restart the container that was started before, so this is the case, so you restart the container of the XTDrone that you modified before, instead of running the following command again, it will create a new container for you. Note that it was started before restarting. Use the command in the picture below for the container.
sudo docker run -p 6080:80 -p 5900:5900 -e RESOLUTION=1920x1080 -v /dev/shm:/dev/shm xtdrone-melodic
Then the ID of the simulation docker image container of Prometheus based on XTDrone docker I am getting this time is c08ef8110bd9
Next time I restart the computer and then start this container command I think it should be docker run c08ef8110bd9
