[feature] A DSL atop OAM primitives about kubevela HOT 6 CLOSED

I tried cdk8s Python SDK to generate a deployment and a service manifests, and it is cool to deploy a webservice with just a few lines of code per https://github.com/awslabs/cdk8s/blob/master/docs/getting-started/python.md.

But AFAIK, the current version of cdk8s might not be good enough.

user

• It took me 4 hours to have the build environment setup. (You can ignore this as it seems that @wonderflow fixed the issue very quickly cdk8s-team/cdk8s#166 (comment))
• There are more than a doze of project initiation issues which is the very first important step.
• cdk8s depends a lot: NodeJS, Python, pipenv, and their suitable versions in documentation are ambiguous.
• It just supports Python/Typescript, or maybe Java too as the Cli said yes, but the doc didn't mention.

developer

• We developers have to be familiar with Python/Java/Typescript, and need to implement more languages for SDK, I believe Golang is a must-have.
• A developer has to learn NodeJS which cdk8s use to generate manifests.
• Like traits applying, it can happen in runtime situation, while relatively, cdk8s is a static manifest generating tool.

I'd like to proposal another option:
RudrX cli framework itself can be easily wrapped to a Golang SDK for generating OAM manifests. I learn there are some tools for generating one language SDK to others, like the mechanism of releasing Alibaba Cloud SDK in multiple language.

Good idea!

What is the Golang SDK meant to look like?

We will support CUE as Definition template, and compose-like file for complex needs beyond CLI.

I'm working on it.
