func (*Operation) ApplyChartGarden

func (o *Operation) ApplyChartGarden(chartPath, namespace, name string, defaultValues, additionalValues map[string]interface{}) error

ApplyChartGarden takes a path to a chart <chartPath>, name of the release <name>, release's namespace <namespace> and two maps <defaultValues>, <additionalValues>, and renders the template based on the merged result of both value maps. The resulting manifest will be applied to the Garden cluster.

func (*Operation) ApplyChartSeed

func (o *Operation) ApplyChartSeed(chartPath, namespace, name string, defaultValues, additionalValues map[string]interface{}) error

ApplyChartSeed takes a path to a chart <chartPath>, name of the release <name>, release's namespace <namespace> and two maps <defaultValues>, <additionalValues>, and renders the template based on the merged result of both value maps. The resulting manifest will be applied to the Seed cluster.

func (*Operation) ChartInitializer

func (o *Operation) ChartInitializer(chartName string, values map[string]interface{}) terraformer.Initializer

ChartInitializer initializes a terraformer based on the given chart and values.

func (*Operation) ComputeAlertManagerHost

func (o *Operation) ComputeAlertManagerHost() string

ComputeAlertManagerHost computes the host for alert manager.

func (*Operation) ComputeGrafanaHosts

func (o *Operation) ComputeGrafanaHosts() []string

ComputeGrafanaHosts computes the host for both grafanas.

func (*Operation) ComputeGrafanaOperatorsHost

func (o *Operation) ComputeGrafanaOperatorsHost() string

ComputeGrafanaOperatorsHost computes the host for users Grafana.

func (*Operation) ComputeGrafanaUsersHost

func (o *Operation) ComputeGrafanaUsersHost() string

ComputeGrafanaUsersHost computes the host for operators Grafana.

func (*Operation) ComputeIngressHost

func (o *Operation) ComputeIngressHost(prefix string) string

ComputeIngressHost computes the host for a given prefix.

func (*Operation) ComputeKibanaHost

func (o *Operation) ComputeKibanaHost() string

ComputeKibanaHost computes the host for kibana.

func (*Operation) ComputePrometheusHost

func (o *Operation) ComputePrometheusHost() string

ComputePrometheusHost computes the host for prometheus.

func (*Operation) DeleteClusterResourceFromSeed

func (o *Operation) DeleteClusterResourceFromSeed(ctx context.Context) error

DeleteClusterResourceFromSeed deletes the `Cluster` extension resource for the shoot in the seed cluster.

func (*Operation) GetSecretKeysOfRole

func (o *Operation) GetSecretKeysOfRole(kind string) []string

GetSecretKeysOfRole returns a list of keys which are present in the Garden Secrets map and which are prefixed with <kind>.

func (*Operation) InitializeMonitoringClient

func (o *Operation) InitializeMonitoringClient() error

InitializeMonitoringClient will read the Prometheus ingress auth and tls secrets from the Seed cluster, which are containing the cert to secure the connection and the credentials authenticate against the Shoot Prometheus. With those certs and credentials, a Prometheus client API will be created and attached to the existing Operation object.

func (*Operation) InitializeSeedClients

func (o *Operation) InitializeSeedClients() error

InitializeSeedClients will use the Garden Kubernetes client to read the Seed Secret in the Garden cluster which contains a Kubeconfig that can be used to authenticate against the Seed cluster. With it, a Kubernetes client as well as a Chart renderer for the Seed cluster will be initialized and attached to the already existing Operation object.

func (*Operation) InitializeShootClients

func (o *Operation) InitializeShootClients() error

InitializeShootClients will use the Seed Kubernetes client to read the gardener Secret in the Seed cluster which contains a Kubeconfig that can be used to authenticate against the Shoot cluster. With it, a Kubernetes client as well as a Chart renderer for the Shoot cluster will be initialized and attached to the already existing Operation object.

func (*Operation) InjectSeedSeedImages
