Add arm dockerfile and update README

[yebo29]

I needed to run it on my Raspberry Pi, so I created a new Dockerfile that uses the ARM version of the alpine image. I also had to learn how to properly build it, so I added it to the readme.

Alternatively, a new ARM docker image could be created with the arm64v8 tag and uploaded to docker hub and then all the user would have to do is modify their docker-compose file to pull that image instead. README would reflect that. If that route is taken then this PR can be closed.

[AndrewPaglusch]

Thank you for the PR! I plan on reviewing this with the rest of the team this Friday.

[AndrewPaglusch]

@yebo29 Do you think you will be able to make the corrections I listed on October 28th?

[yebo29]

I will be completely honest with you ... I am just now seeing this. I am so very sorry!! Yes I can make the requested changes. I will work on this tomorrow. I truly apologize for not seeing this.

[yebo29]

I'll be testing the alpine image soon. README has been updated.

[AndrewPaglusch]

@yebo29 Do you still have more work or testing to do, or is this PR ready for our review?

[yebo29]

@AndrewPaglusch I see you marked the comment on the Dockerfile as resolved, so yes, this is ready for review!

[yebo29]

I have this running successfully on my Raspberry Pi 4 at home.

[yebo29]

@mattburchett Roger. I'll work on implementing those changes.

[yebo29]

@mattburchett I've uploaded the changes but have not tested them. I will do so at some point today.

[yebo29]

Sorry; a little delayed. Testing now.

dcufl is an alias in my shell for docker-compose up -d && docker-compose logs --follow I also added a variable to make updates easier. It can be removed if you prefer. I have other updates that I can submit in a separate PR.
