# End-to-end tests
|
|
|
|
## With [kind](https://kind.sigs.k8s.io/)
|
|
|
|
[`kind`](https://kind.sigs.k8s.io/) 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.
|
|
|
|
```bash
|
|
KIND_E2E=true make test-e2e
|
|
```
|
|
|
|
## With an existing Kubernetes cluster
|
|
|
|
If you already have a Kubernetes cluster, you can use:
|
|
|
|
```bash
|
|
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.
