Conquering Kubernetes with Emacs

Specific Annoying workflow

Listing pods with kubectl get pods, then select a pod name and copy paste it into kubectl logs [pod name]

Why?

I want to streamline my workflow and stop using the terminal
learn more about kubernetes
main kubernetes extension for Emacs out there is greedy for permissions

Documentation-Driven Development

The philosophy behind Documentation-Driven Development is a simple: from the perspective of a user, if a feature is not documented, then it doesn't exist, and if a feature is documented incorrectly, then it's broken.

Document the feature first. Figure out how you're going to describe the feature to users; if it's not documented, it doesn't exist. Documentation is the best way to define a feature in a user's eyes.
Whenever possible, documentation should be reviewed by users (community or Spark Elite) before any development begins.
Once documentation has been written, development should commence, and test-driven development is preferred.
Unit tests should be written that test the features as described by the documentation. If the functionality ever comes out of alignment with the documentation, tests should fail.
When a feature is being modified, it should be modified documentation-first.
When documentation is modified, so should be the tests.
