Introduction

When you start your docker run the container stops immediately, it is possible that your PID 1 did not start, however you do not see anything in the logs and cannot check in your container.
We will see how to debug a Docker container that stops immediately, by forcing a command on it at PID 1.

Course

Restart your docker run with the command below:

$ docker run -d --name NOM_DE_VOTRE_CONTENEUR NOM_DE_VOTRE_IMAGE /bin/sh -c "while true; do sleep 2; df -h; done"

This will make your PID 1 will still be running, so you can check in your container if your services are running and debug them.
