#207 - Simplified docker-compose and added support for testnet

[thehenrytsai]

1. added testnet docker support
2. simplified docker-compose files, so now it is a one-command deployment
3. introduced the usage of ION docker images

Looking for people who are willing to test the new docker instructions before this is merged.

Hi, I tried this following readme.md. But readme.md's docker-compose version is old. I think it shold be changed "sudo curl -L https://github.com/docker/compose/releases/download/v2.6.0/docker-compose-`uname -s-uname -m` -o /usr/local/bin/docker-compose"

@monakaJP, thank you for trying out the README.md, I have updated the curl command based on your feedback. Were you able to progress further and run an ION node successfully?

@thehenrytsai Hi. it was succeeded on Ubuntu 20.04. DID can now be resolved. If anything, a docker image for linux would be nice. I made it on dockerhub https://hub.docker.com/r/monakajp/ion/tags.

a docker image for linux would be nice.

Hi @monakaJP, thanks for the fast response, I am not clear what you mean by a Linux docker image? The ION docker-image is already based off Linux (alpine), but I guess that’s not what you mean?

@thehenrytsai I'm sorry for I didn't explain. Maybe it is cpu architecture problem. I failed to build it on x86_64 environment. So I build new image and used it. I thick we should add another architecture or edit how to build image.

@monakaJP, ah! This is my bad, I forgot that I am developing on a Macbook with M1 chip, as a result it built the ION image in arm64 architecture. Let me look into fixing this!

[thehenrytsai]

@monakaJP, I have updated the docker README and pushed a multi-platform ION image!

[monakaJP]

@thehenrytsai Great. Thank you for upgrade!

With today's commit, I think the PR is ready for final review and merge, will let this hang for a couple more days for more comments.
