prometheus-adapter/test

End-to-end tests

With kind

kind and kubectl are automatically downloaded except if SKIP_INSTALL=true is set. A kind cluster is automatically created before the tests, and deleted after the tests. The prometheus-adapter container image is build locally and imported into the cluster.

KIND_E2E=true make test-e2e

With an existing Kubernetes cluster

If you already have a Kubernetes cluster, you can use:

KUBECONFIG="/path/to/kube/config" REGISTRY="my.registry/prefix" make test-e2e

• The cluster should not have a namespace prometheus-adapter-e2e. The namespace will be created and deleted as part of the E2E tests.
• KUBECONFIG is the path of the kubeconfig file. Optional, defaults to ${HOME}/.kube/config
• REGISTRY is the image registry where the container image should be pushed. Required.

Additional environment variables

These environment variables may also be used (with any non-empty value):

• SKIP_INSTALL: skip the installation of kind and kubectl binaries;
• SKIP_CLEAN_AFTER: skip the deletion of resources (Kind cluster or Kubernetes namespace) and of the temporary directory .e2e;
• CLEAN_BEFORE: clean before running the tests, e.g. if SKIP_CLEAN_AFTER was used on the previous run.
