proposal: cli to install & run kubernetes applications as turnkey solutions

[AmitKumarDas]

ProblemStatement: As a kubernetes engineer I would like to install, run & verify one or more applications (that includes required controllers) on my preferred kubernetes cluster. I want a cli that can help me achieve my goal.

NOTE: I do not want to deal with HELM or other tools to achieve this. NOTE: I do not want to configure yamls to achieve my purpose. NOTE: This cli should provide me an opinionated solution.

Use Cases

• Ability to test my K8s controller using a mocked kubernetes control plane
• Ability to install, run & test Cassandra on OpenEBS local PV on GKE
• Ability to install & verify CStorPool operator in my E2E pipelines

Notes:

• Mocked k8s control plane implies k8s api server binary, etcd binary & kubectl talking to each other

Draft Thoughts on CLI

• This is an example of installing, running & verifying cassandra that makes use of OpenEBS local PV.

  $ kubectl nocode download --pack=cassandra
  $ kubectl nocode run --pack=cassandra
  $ kubectl nocode verify --pack=cassandra

  $ kubectl nocode download --pack=tcid-cassandra-on-openebs-localpv
  $ kubectl nocode run --pack=tcid-cassandra-on-openebs-localpv
  $ kubectl nocode verify --pack=tcid-cassandra-on-openebs-localpv
