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

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) 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.
