Kubernetes test

Notes

This test verifies that youki works correctly as a container runtime in a Kubernetes environment using Kind (Kubernetes in Docker).

Single Node deploy test

The test builds a custom Kind node image with youki, creates a cluster, and deploys nginx pods using a RuntimeClass that specifies youki as the runtime.

Local

$ just test-kind

To clean up an existing Kind cluster first:

$ just clean-test-kind

Multi Node deploy test

In addition to the single-node test-kind flow above, there is a multi-node variant that mirrors how youki would be installed on a real Kubernetes cluster: the cluster nodes themselves stay as vanilla kindest/node images, and a DaemonSet running on every node installs youki onto the host and registers it with containerd at runtime.

Local

$ just test-kind-deploy

Or to only stand up the cluster + DaemonSet without the nginx smoke test:

$ just kind-deploy

Clean up:

$ just clean-test-kind-deploy
