Dockerfile CMD instruction will exit the container just after running it

Question

I want to setup some configuration when my container starts, for this I am using shell scripts. But my container will exits as soon as my scripts ends, I have tried with -d

Answer 1

You can also modify your first Dockerfile, replacing

CMD /usr/local/bin/shell.sh

by

CMD /usr/local/bin/shell.sh ; sleep infinity

That way, your script does not terminate, and your container stays running.
