Suppose we now have the following image
1: Start with a simple container
docker container run // used to start a container
-it // container is interactive, and connected to the terminal
Command: docker container run --name percy -it ubuntu: latest / bin / bash // start a container, named percy
2: Exit container and keep the container operation
Run the terminal command ps -elf can view the processes running in the container, the first process is to run the Bash Shell, the second process is a temporary process, generated by ps -elf, command executing the process will end.
Press Ctrl-PQ: key combination will exit the container, but the container will not stop running.
Note: If you enter exit at the Bash Shell Bash Shell exits, this time due to the container without any process running, the container itself will be killed.
3: Check the container list
4: Life cycle of container
Execute the following command, and then press Ctrl-PQ exit container
Use docker container stop percy stop the container
Restart the container and try to bash even
NOTE: Before deleting a container, the container will not lose the data. If the container is stored in the volume, even if the container is removed, the data will be saved.
5: stop the container
Container running docker container rm <container> -f // Destruction
6: Restart container policy
always: unless the container is explicitly stopped, such as by docker container stop command, otherwise the container will always try to restart a stopped state.
docker container run --name neve --restart always -it ubuntu:latest /bin/bash
You can see the container created before 23s, launched in 7s ago
There unless-stopped and restarted on-failure policy, which is not presented here.
7: Remove container
快速清理所有容器可以用：docker container rm $(docker container ls -aq) -f //-f:表示强制执行清理命令
