End-to-end tests for konnectivity-network-proxy running in a kind cluster

These e2e tests deploy the KNP agent and server to a local kind cluster to verify their functionality.

These can be run automatically using make e2e-test.

Setup in main_test.go

Before any of the actual tests are run, the TestMain() function in main_test.go performs the following set up steps:

• Spin up a new kind cluster (4 control plane and 4 worker nodes) with the node image provided by the -kind-image flag.
• Sideload the KNP agent and server images provided with -agent-image and -server-image into the cluster.
• Deploy the necessary RBAC and service templates for both the KNP agent and server (see renderAndApplyManifests).

The tests

static_count_test.go

These tests deploy the KNP servers and agents to the previously created kind cluster. After the deployments are up, the tests check that both the agent and server report the correct number of connections on their metrics endpoints.

lease_count_test.go

Similar to static_count_test.go, except using the new lease-based server counting system rather than passing the server count to the KNP server deployment as a CLI flag.
