How to keep running after exiting Docker container

Phenomenon:

Run an image, for example, ubuntu14.04:

docker run -it --rm ubuntu:14.04 bash

On exit:

Execute Ctrl+D or execute exit

View the thread:

docker ps

It is empty, indicating that there is no running container.

Solution:

Run an image:

docker run -dit ubuntu:14.04

View the thread:

Found a thread and opened it:

docker attach 【CONTAINER ID or NAMES】

If you want to continue running when exiting: press [ctrl+p], [ctrl+q] in sequence

If you do not want to continue running: press [ctrl+d] or enter exit

In addition: To restart after shutdown, please enter: docker restart [CONTAINER ID or NAMES]

Supplement: Docker - Avoid running a shell script after starting the container and then exiting the container after the execution is completed

Recently, I was using Dockerfile to start a container and found that when I used Dockerfile to call the shell in the container, Docker would exit the container after the shell was executed.

analyze

When Docker executes the shell, it executes it in the background; therefore, after the shell is executed, Docker detects that there is no foreground task to be executed and exits the container.

Workaround

Add a "never complete" command to the end of the shell script:

# tail -f /dev/null

In this way, when this command is executed, the shell will not exit, and the container will not exit either.

The above is my personal experience. I hope it can give you a reference. I also hope that you will support 123WORDPRESS.COM. If there are any mistakes or incomplete considerations, please feel free to correct me.
