A recent project has a launch container that automatically executes a script to launch an app, and finds that the container exits automatically when the script finishes executing. problem Analysis a Docker container can manage only one process at a time, and when the process exits, the container exits, and of course a container may run multiple processes at the same time. After the container has started executing a script, the process is finished and the other processes are finished, so the container exits automatically, and the solution: we can keep the script running without stopping.
The solution adds tail-f/dev/null to the last line of the script, which is never done, so the script will never be executed, so the container does not quit.
