Functions

func AddRegistryCacheExtension

func AddRegistryCacheExtension(shoot *gardencorev1beta1.Shoot, caches []v1alpha1.RegistryCache)

AddRegistryCacheExtension adds registry-cache extension with the given caches to the given Shoot.

func HasRegistryCacheExtension

func HasRegistryCacheExtension(shoot *gardencorev1beta1.Shoot) bool

HasRegistryCacheExtension returns whether the Shoot has an extension of type registry-cache.

func RemoveRegistryCacheExtension

func RemoveRegistryCacheExtension(shoot *gardencorev1beta1.Shoot)

RemoveRegistryCacheExtension removes registry caches extensions from given Shoot.

func VerifyRegistryCache

func VerifyRegistryCache(parentCtx context.Context, log logr.Logger, shootClient kubernetes.Interface, upstream, nginxImageWithDigest string)

VerifyRegistryCache verifies that a registry cache works as expected.

The verification consists of the following steps:

1. It deploys an nginx Pod with the given image.
2. It waits until the Pod is running.
3. It verifies that the image is present in the registry's scheduler-state.json file. This is a verification that the image pull happened via the registry cache (and the containerd didn't fall back to the upstream).

func VerifyRegistryConfigurationsAreRemoved

func VerifyRegistryConfigurationsAreRemoved(ctx context.Context, log logr.Logger, shootClient kubernetes.Interface, upstreams []string)

VerifyRegistryConfigurationsAreRemoved verifies that configure-containerd-registries.service systemd unit gets deleted and the hosts.toml files for the given upstreams are removed. The hosts.toml file and the systemd unit are deleted by a DaemonSet by the registry-cache extension.

Note that for a Shoot cluster provider-local adds hosts.toml files for localhost:5001, gcr.io, eu.gcr.io, ghcr.io, registry.k8s.io and quay.io. Hence, when a registry cache is removed for one of the above upstreams, then provider-local's hosts.toml file will still exist.

func WaitUntilRegistryConfigurationsAreApplied

func WaitUntilRegistryConfigurationsAreApplied(ctx context.Context, log logr.Logger, shootClient kubernetes.Interface)

WaitUntilRegistryConfigurationsAreApplied waits until the configure-containerd-registries.service systemd unit gets active on the Nodes. The unit will be in activating state until it configures all registry caches.
