For CI (testing) we use tekton [1] to run tests and pass around artifacts inside k8s. You can kick off and monitor tekton builds with their CLI tool, but we ended up building our own create/monitor/download-artifacts tool for it in ruby. We use an off the shelf CI server to kick that tool off, and it dumps back results the CI server can understand.

One of the things we need to do is elastically scale the number of tasks (basically pods in tekton) that comprise our test suite run. This might be based on cluster utilization or whether it's the master branch. Since we have a single threaded test suite, we hoist parallelism up to the k8s level by breaking apart the tests into partitions each run by its own pod. For this we just render processed and parameterized erb to yaml. Eventually we'll dispense with yaml altogether and programmatically construct resources using a k8s REST api client.

We haven't moved into CD with any of this tooling yet.
