Thanks for the great introduction to Docker!
If you follow the tutorial and like me have the error
Error response from daemon: Dockerfile parse error line 4: unknown instruction: /HOME/NODE/APPduring
docker build, then replace lines 3,4 inDockerfilewith one line.From

Looks like that was a formatting error in the markdown – should be fixed now. That instruction is definitely all one line. Thanks for catching!
To keep the image as small as possible you can delete the cache npm builds
And by putting "fix" settings that don't change, like

If you can install
podman, you no longer need a sudo account as podman can work without root access. It works just likedocker, using the very same parameters. You can evenalias docker=podman.Also, why creating

Do we make static websites with express?
thank you!
Thanks for the easy to understand guide. I needed this for an upcoming project.
