Development

Setup a development environment

To setup a development environment, make sure you installed the following tools:

• tofu
• k3sup
• docker
• skaffold

1. Configure a HCLOUD_TOKEN in your shell session.

[!WARNING] The development environment runs on Hetzner Cloud servers which will induce costs.

2. Deploy the development cluster:

make -C dev up

3. Load the generated configuration to access the development cluster:

source dev/files/env.sh

4. Check that the development cluster is healthy:

kubectl get nodes -o wide

5. Start developing the CSI driver in the development cluster:

skaffold dev

On code change, skaffold will rebuild the image, redeploy it and print all logs from csi components.

⚠️ Do not forget to clean up the development cluster once are finished:

make -C dev down

Run the docker e2e tests

To run the integrations tests, make sure you installed the following tools:

• docker

1. Run the following command to run the integrations tests:

go test -v -tags integration ./test/integration

Run the kubernetes e2e tests

The Hetzner Cloud CSI driver is tested against the official kubernetes e2e tests.

Before running the integrations tests, make sure you followed the Setup a development environment steps.

1. Run the kubernetes e2e tests using the following command:

make -C test/e2e/kubernetes test
