Operation contains all data required to perform an operation on a Shoot cluster.

func New

func New(shoot *gardencorev1alpha1.Shoot, config *config.GardenletConfiguration, logger *logrus.Entry, k8sGardenClient kubernetes.Interface, k8sGardenCoreInformers gardencoreinformers.Interface, gardenerInfo *gardencorev1alpha1.Gardener, secretsMap map[string]*corev1.Secret, imageVector imagevector.ImageVector) (*Operation, error)

New creates a new operation object with a Shoot resource object.

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) CleanShootTaskError

func (o *Operation) CleanShootTaskError(ctx context.Context, taskID string)

CleanShootTaskError removes the error with taskID from the Shoot's status.LastErrors array. If the status.LastErrors array is empty then status.LastError is also removed.

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

func (o *Operation) InjectSeedSeedImages(values map[string]interface{}, names ...string) (map[string]interface{}, error)

InjectSeedSeedImages injects images that shall run on the Seed and target the Seed's Kubernetes version.

func (*Operation) InjectSeedShootImages

func (o *Operation) InjectSeedShootImages(values map[string]interface{}, names ...string) (map[string]interface{}, error)

InjectSeedShootImages injects images that shall run on the Seed but target the Shoot's Kubernetes version.

func (*Operation) InjectShootShootImages

func (o *Operation) InjectShootShootImages(values map[string]interface{}, names ...string) (map[string]interface{}, error)

InjectShootShootImages injects images that shall run on the Shoot and target the Shoot's Kubernetes version.

func (*Operation) ReportShootProgress

func (o *Operation) ReportShootProgress(ctx context.Context, stats *flow.Stats)

ReportShootProgress will update the last operation object in the Shoot manifest `status` section by the current progress of the Flow execution.

func (*Operation) SeedVersion

func (o *Operation) SeedVersion() string

SeedVersion is a shorthand for the kubernetes version of the K8sSeedClient.

func (*Operation) ShootVersion

func (o *Operation) ShootVersion() string

ShootVersion is a shorthand for the desired kubernetes version of the operation's shoot.

func (*Operation) SyncClusterResourceToSeed

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

SyncClusterResourceToSeed creates or updates the `Cluster` extension resource for the shoot in the seed cluster. It contains the shoot, seed, and cloudprofile specification.
