In this Docker blog post, I will show you how to keep a Docker container running and not exiting.
Docker containers are great for developers because they can run an application in a specific environment without installing the software locally.
One issue can arise when using Docker containers: they exit after being idle for too long! In this article, I’ll show you how to prevent your docker container from exiting with some simple methods.
How To Keep a Docker Container Running and Not Exiting
To keep a Docker container from exiting, you can use the “-d” flag when running the container to detach it and run it in the background.
Additionally, make sure that the container is running a process that doesn’t exit on its own.
If the container is exiting immediately, check the logs using “docker logs <container_name>” to see if there are any errors causing the premature exit.
To keep your containers running and exiting, I have two options for you to use that will not let the container go ideal and exit. Use either of the two (We would like to use the second option).
