Improve docker-compose installation method:

[umer936]

1. proper variable usage in docker-compose.yml
2. put provision.sh inline of the Dockerfile
3. make container not rely on root user -- fixes npm permissions issue
4. define all versions at top of Dockerfile
5. Bail early if /app not mounted

Feel free to modify as desired, but this means the container does not rely on npm being installed on the host system and it fixed the issues I was facing regarding npm failing permissions due to being run as root.

hmm may need a note in the install instructions that the dpo-voyager folder needs to be writable by all (chmod a+w .) bc npm install makes node_modules, dist, and package-lock.json

alternatively could have the folders (e.g. files, node_modules, and dist) included in the repo with just a .gitkeep file in the folders

if you're ok with the first, I'll make the PR on the docs as well

Thanks for the PR @umer936, we will take a look.

Can you describe the install process you are following in more detail? None of the installs we have on Windows or RHEL have a project folder that is writable by all.

So the issue I was trying to solve with this is that I don't have NPM installed on my host system, just in the docker container and it was giving a lot of permissions issues.

I had this happen on 2 machines by two of us, one on Windows and one of us on RockyLinux.

When I attempted to just run docker-compose up, I encountered errors like this (not using sudo):

and Google led me to that being due to the user in the Dockerfile being root and then npm being upset that I'm trying to run it as root. I figured this was due to conflicts in the user being used to build the container, hence the rework of the Dockerfile/start.sh/provision.sh.

That said, I started from scratch just now and didn't have an issue at all... I'm not sure where the permissions issue was stemming from. I haven't run through the commits you've done since last I pulled. Maybe it was an npm package version issue, or maybe it was user error.

I'll close this issue/PR because I can't replicate it today.

Let me know if you want me to commit the integrating start.sh into the Dockerfile, but also feel free to ignore.

@umer936 Thanks for the extra context. I'm definitely interested in this PR since if you encountered the issue twice, odds are that others have as well. I just want to understand the underlying issue before making the change. If you come across any more info on what might have been different between your working/not working deployments, please do reopen. Thanks!
