adding dockerfile

[shanehughes1990]

This adds a simple docker file for container deployment, Adding in the redwood-config for a default setup, users will need to create the cert and mount into the container but otherwise works.

A sample docker run command to get going, this requires you to have a cert.pem/key.pem in your current working directory.

docker run -d -p 6502:6502 -p 6510:6510 \
	-v $PWD/cert.pem:/etc/redwood/root.pem \
	-v $PWD/key.pem:/etc/redwood/root_key.pem \
	docker.io/library/redwood:latest

Adding a dockerfile sounds like a good idea. It should probably go in the startup directory along with the init scripts. It would be good to provide some documentation (maybe in a README-docker.md file, not just in the pull request comment).

perfect I can do that, I wasn't sure how/where you wanted it all Ill move things around and create a doc for it.

The docker file is built for amd64 platforms only but should be built in such a way that would allow cross platform builds.
I want to build a container for ARM and ARM64 devices such as Mikrotik RouterOS devices which I already have.

[shanehughes1990]

yeah you build with buildx this is just something I figured I would put a PR in for because I needed one for our use case.

@shanehughes1990 I am working on a buildx compatible Dockerfile, there is no reason to use a global Dockerfile with CPU specific build instructions.
