@martinda Yeah That is the error I am talking about in the description. It cannot find the file to copy even though it should be able to copy everything. One of the reasons is the dockerignore, it is not allowing anything to be copied

[martinda]

Then the .dockerignore needs to be fixed to allow files to go to the context of what the docker images do need to copy. For example, to reveal the pom.xml adding this line to the .dockerignore` works:

!**/pom.xml

[martinda]

What is the goal at the end of this PR? Is it to run just docker commands and no maven commands?

[sladyn98]

@martinda Yes the goal is to be able to run without maven because every user might not have maven installed

[sladyn98]

@martinda updated docker ignore

[kwhetstone]

This should include changes to the readme to run the commands as well.

[sladyn98]

This works fine for me and the readme is perfect. No additional commands required

[martinda]

It work for me too. I think this is very good. No need to locally build, it builds itself in images.

I am not an expert in docker image and container management, maybe the infra team will have feedback on how to manage this in the future. For now I think we can accept this PR.
