This controller operates on the Network resource in the extensions.gardener.cloud/v1alpha1 API group. It manages those objects that are requesting cilium Networking configuration (.spec.type=cilium):
apiVersion: extensions.gardener.cloud/v1alpha1
kind: Network
metadata:
name: cilium-network
namespace: shoot--foo--bar
spec:
type: cilium
podCIDR: 10.244.0.0/16
serviceCIDR: 10.96.0.0/24
providerConfig:
apiVersion: cilium.networking.extensions.gardener.cloud/v1alpha1
kind: NetworkConfig
# hubble:
# enabled: true
# store: kubernetesPlease find a concrete example in the example folder. All the cilium specific configuration
should be configured in the providerConfig section. If additional configuration is required, it should be added to
the networking-cilium chart in controllers/networking-cilium/charts/internal/cilium/values.yaml and corresponding code
parts should be adapted (for example in controllers/networking-cilium/pkg/charts/utils.go).
Once the network resource is applied, the networking-cilium controller would then create all the necessary managed-resources which should be picked
up by the gardener-resource-manager which will then apply all the
network extensions resources to the shoot cluster.
Finally after successful reconciliation an output similar to the one below should be expected.

observedGeneration: 1You can run the controller locally on your machine by executing make start. Please make sure to have the kubeconfig pointed to the cluster you want to connect to.
Static code checks and tests can be executed by running make verify. We are using Go modules for Golang package dependency management and Ginkgo/Gomega for testing.
