Types

type HybridBotanist

type HybridBotanist struct {
	*operation.Operation
	Botanist           *botanist.Botanist
	SeedCloudBotanist  cloudbotanist.CloudBotanist
	ShootCloudBotanist cloudbotanist.CloudBotanist
}

HybridBotanist is a struct which contains the "normal" Botanist as well as the CloudBotanist. It is used to execute the work for which input from both is required or functionalities from both must be used.

func New

func New(o *operation.Operation, b *botanist.Botanist, seedCB, shootCB cloudbotanist.CloudBotanist) (*HybridBotanist, error)

New takes an operation object <o>, a Botanist object <b>, and two CloudBotanist objects <seedCB> and <shootCB>, and creates a new HybridBotanist object.

func (*HybridBotanist) ComputeShootOperatingSystemConfig

func (b *HybridBotanist) ComputeShootOperatingSystemConfig() error

ComputeShootOperatingSystemConfig generates the shoot operating system configuration. Both, the downloader and original configuration will be generated and stored in the shoot specific cloud config map for later usage.

func (*HybridBotanist) DeployCSIControllers

func (b *HybridBotanist) DeployCSIControllers() error

DeployCSIControllers deploy CSI controllers into the Shoot namespace in the Seed cluster. They include CSI plugin controller service (Provider specific), CSI external attacher, CSI external provisioner and CSI snapshotter.

func (*HybridBotanist) DeployCloudControllerManager

func (b *HybridBotanist) DeployCloudControllerManager() error

DeployCloudControllerManager asks the Cloud Botanist to provide the cloud specific configuration values for the cloud-controller-manager deployment.

func (*HybridBotanist) DeployCloudProviderConfig

func (b *HybridBotanist) DeployCloudProviderConfig() error

DeployCloudProviderConfig asks the Cloud Botanist to provide the cloud specific values for the cloud provider configuration. It will create a ConfigMap for it and store it in the Seed cluster.

func (*HybridBotanist) DeployETCD

func (b *HybridBotanist) DeployETCD() error

DeployETCD deploys two etcd clusters via StatefulSets. The first etcd cluster (called 'main') is used for all the data the Shoot Kubernetes cluster needs to store, whereas the second etcd luster (called 'events') is only used to store the events data. The objectstore is also set up to store the backups.

func (*HybridBotanist) DeployETCDStorageClass

func (b *HybridBotanist) DeployETCDStorageClass(ctx context.Context) error

DeployETCDStorageClass create the high iops storageclass required for volume used by etcd pods in seed cluster.

func (*HybridBotanist) DeployKubeAPIServer

func (b *HybridBotanist) DeployKubeAPIServer() error

DeployKubeAPIServer asks the Cloud Botanist to provide the cloud specific configuration values for the kube-apiserver deployment.

func (*HybridBotanist) DeployKubeAPIServerService

func (b *HybridBotanist) DeployKubeAPIServerService() error

DeployKubeAPIServerService asks the Cloud Botanist to provide the cloud specific configuration values for the kube-apiserver service.

func (*HybridBotanist) DeployKubeAddonManager

func (b *HybridBotanist) DeployKubeAddonManager() error

DeployKubeAddonManager deploys the Kubernetes Addon Manager which will use labeled Kubernetes resources in order to ensure that they exist in a cluster/reconcile them in case somebody changed something.

func (*HybridBotanist) DeployKubeControllerManager

func (b *HybridBotanist) DeployKubeControllerManager() error

DeployKubeControllerManager asks the Cloud Botanist to provide the cloud specific configuration values for the kube-controller-manager deployment.

func (*HybridBotanist) DeployKubeScheduler

func (b *HybridBotanist) DeployKubeScheduler() error

DeployKubeScheduler asks the Cloud Botanist to provide the cloud specific configuration values for the kube-scheduler deployment.

func (*HybridBotanist) DeployLimitedNetworkPolicies

func (b *HybridBotanist) DeployLimitedNetworkPolicies(ctx context.Context) error

DeployLimitedNetworkPolicies creates a network policies in a Shoot cluster's namespace that DOES NOT deny all traffic and allow certain components to use annotations to declare their desire to transmit/receive traffic to/from other Pods/IP addresses. This is needed until migration to the new policies is complete.

func (*HybridBotanist) DeployNetworkPolicies

func (b *HybridBotanist) DeployNetworkPolicies(ctx context.Context) error

DeployNetworkPolicies creates a network policies in a Shoot cluster's namespace that deny all traffic and allow certain components to use annotations to declare their desire to transmit/receive traffic to/from other Pods/IP addresses.

func (*HybridBotanist) RefreshCSIControllersChecksums

func (b *HybridBotanist) RefreshCSIControllersChecksums() error

RefreshCSIControllersChecksums updates the cloud provider checksum in the kube-controller-manager pod spec template.

func (*HybridBotanist) RefreshCloudProviderConfig

func (b *HybridBotanist) RefreshCloudProviderConfig() error

RefreshCloudProviderConfig asks the Cloud Botanist to refresh the cloud provider config in case it stores the cloud provider credentials. The Cloud Botanist is expected to return the complete updated cloud config.
