Add helm charts

[sfxworks]

As a submodule since I plan to do a lot with prow and CI.

Relates to #362

• k8s deployment by referencing simplified values
• Compatible with helm 3
• Deploys service type NodePort and encourages SRV records instead of 1 server per IP models
• Will include future updates like SSH and Web for the Dynmap / web of things

Thank you for submitting this, but I would prefer not to bring a submodule into the repository. Please review my suggestion from the issue

I think it would be great to have a "Deployment Examples" (or something like that) section in the README that would list sources like yours along with the server-only Helm chart https://github.com/helm/charts/tree/master/stable/minecraft . Selfishly, I can also throw in my not-so-elegant kubernetes deployment file I copy-tweak-paste :)

Additionally, I just discovered Helm Hub has a process to submit additional chart repos into their Hub. I would recommend pursuing that and then the new "Deployment Examples" section that provide helm instructions to utilize that:

https://github.com/helm/hub/blob/master/Repositories.md

That will take some time since I'd have to alter it a bit more/await helm/repo/charts for PR approval, but I could do that! Sounds like a plan.

[itzg]

Thanks. If it helps I could create a starter README in the examples directory that in turn can be referenced from the top of the main README. I think a small paragraph with a link to your repo https://github.com/mcserverhosting-net/charts would be sufficient since you then provide all the helm repo operations a user would need there.

That would be great! I have the week off so I'm planning to continue working on the charts throughout.

Can you see if #461 works for you?

I am going to close this since official Helm charts have since been moved to https://github.com/itzg/minecraft-server-charts
