Constants

const (
	// ServiceAccountJSON is a constant for the key in a cloud provider secret that holds the Google service account.
	ServiceAccountJSON = "serviceaccount.json"
	// ProjectID is a constant for the key in a Google service account storing the project id.
	ProjectID = "project_id"
)

Functions

func ExtractProjectID

func ExtractProjectID(ServiceAccountJSON []byte) (string, error)

ExtractProjectID extracts the value of the key "project_id" from the service account JSON document.

func MinifyServiceAccount

func MinifyServiceAccount(serviceAccountJSON []byte) (string, error)

MinifyServiceAccount uses the provided service account JSON objects and minifies it. This is required when you want to inject it as environment variable into Terraform.

Types

func (b *GCPBotanist) GenerateCloudProviderConfig() (string, error)

GenerateCloudProviderConfig generates the GCE cloud provider config. See this for more details: https://github.com/kubernetes/kubernetes/blob/master/pkg/cloudprovider/providers/gce/gce.go

func (*GCPBotanist) GenerateEtcdBackupConfig

func (b *GCPBotanist) GenerateEtcdBackupConfig() (map[string][]byte, map[string]interface{}, error)

GenerateEtcdBackupConfig returns the etcd backup configuration for the etcd Helm chart.

func (*GCPBotanist) GenerateKube2IAMConfig

func (b *GCPBotanist) GenerateKube2IAMConfig() (map[string]interface{}, error)

GenerateKube2IAMConfig - Not needed on GCP.

func (*GCPBotanist) GenerateKubeAPIServerConfig

func (b *GCPBotanist) GenerateKubeAPIServerConfig() (map[string]interface{}, error)

GenerateKubeAPIServerConfig generates the cloud provider specific values which are required to render the Deployment manifest of the kube-apiserver properly.

func (*GCPBotanist) GenerateKubeControllerManagerConfig

func (b *GCPBotanist) GenerateKubeControllerManagerConfig() (map[string]interface{}, error)

GenerateKubeControllerManagerConfig generates the cloud provider specific values which are required to render the Deployment manifest of the kube-controller-manager properly.
