How to exit docker after entering the container

Docker is a popular containerization platform that helps developers package applications into portable containers and provides many convenient tools and commands to manage these containers. One of the common commands is to enter the Docker container in order to access the files and operating system inside it.

However, how to exit the container after entering it? This is a question that beginners can easily get confused about. This article will introduce two methods to exit the container.

Method 1: Use the exit command

Within the container, the "exit" command can be used to safely exit the container and return to the host system. This command will stop the container and delete it. For example, assuming you have entered a Docker container named "my_container", you can exit it using the following command:

# exit

After executing this command, you will see a message stating that the container has been stopped and deleted .

# exit
exit

This method is suitable for situations where container state or file system changes do not need to be preserved. If you need to preserve container state or file system changes, you can use the second method.

Method 2: Use the Ctrl P, Ctrl Q key combination

Another way to exit the Docker container is to use the Ctrl P, Ctrl Q key combination. This method puts the container into the background without stopping it or deleting it.

Assuming you have entered a Docker container named "my_container", you can use the following steps to put the container into the background:

1. Press the Ctrl P key and do not release it it.
2. Press the Ctrl Q keys again and release them at the same time. The container will enter background mode and you will be returned to the command line interface of the host system.

In this case, you can re-enter the container through the "docker attach" command. For example, execute the following command to re-enter a container named "my_container":

# docker attach my_container

With this method, you can preserve the container state and re-enter when needed.

Summary

It is very convenient to enter the Docker container, just use the "docker exec" or "docker run" command. There are two ways to exit the container, one is to use the "exit" command, the other is to use the Ctrl P, Ctrl Q key combination to put the container into the background.
