A brief analysis of how to exit docker ps

Docker is an open source application containerization platform that allows users to run applications in containers, thereby improving application portability and deployability. When using Docker, users may encounter some problems, such as the container not exiting normally. Especially when using the "docker ps" command, users may find that the container cannot exit. This article will introduce how to exit Docker PS and provide solutions.

Docker PS is a command to manage containers. It can list the Docker containers running in the system. By using this command, users can view the status, ID, name, port mapping and other information of all containers. But sometimes, users may encounter a situation where they cannot exit Docker PS. This situation may prevent users from viewing the status information of the container, thus affecting user productivity.

In Docker, if the container cannot be stopped or exited, you can solve it in the following ways:

1. Use CTRL C to force exit
   If the user uses "docker ps" If you find that you cannot exit after executing the command, you can use the CTRL C command to force exit Docker PS. This command can forcefully terminate running programs, including Docker containers.
2. Use the "docker stop" command to stop the container
   If the user cannot exit Docker PS and wants to stop a container, he can use the "docker stop" command to stop the container. This command will send a SIGTERM signal to the container process, which will attempt to exit gracefully.

For example, if you want to stop the container with the container ID "1234", you can execute the following command:

docker stop 1234

3. Use "docker kill "Command to kill the container
   If the container cannot be stopped or exited normally, you can use the "docker kill" command to kill the container. This command will send a SIGKILL signal to the container process, which will terminate immediately. However, it should be noted that when terminating the container using this method, data loss or corruption may occur.

For example, if you want to kill the container with the container ID "1234", you can execute the following command:

docker kill 1234

4. Use "docker rm" command to delete the container
   If the container has stopped running, but the user still cannot exit Docker PS, you can use the "docker rm" command to delete the container. This command will delete all state information of the container and release related system resources.

For example, if you want to delete the container with the ID "1234", you can execute the following command:

docker rm 1234

Through the above methods, the user can Solve the problem of being unable to exit Docker PS and stop, kill or delete related containers.
