	// contains filtered or unexported fields
}

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

func (*Operation) AllSecretKeys

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

AllSecretKeys returns all stored secret keys from the operation. Calling this function is thread-safe.

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.LastErrors is also removed.

func (*Operation) ComputeAlertManagerHost

func (o *Operation) ComputeAlertManagerHost() string

ComputeAlertManagerHost computes the host for alert manager.

func (*Operation) ComputeIngressHost

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

ComputeIngressHost computes the host for a given prefix.

func (*Operation) ComputeKubeAPIServerHost

func (o *Operation) ComputeKubeAPIServerHost() string

ComputeKubeAPIServerHost computes the host with a TLS certificate from a trusted origin for KubeAPIServer.

func (*Operation) ComputePlutonoHost

func (o *Operation) ComputePlutonoHost() string

ComputePlutonoHost computes the host for Plutono.

func (*Operation) ComputePrometheusHost

func (o *Operation) ComputePrometheusHost() string

ComputePrometheusHost computes the host for prometheus.

func (*Operation) ComputeValiHost

func (o *Operation) ComputeValiHost() string

ComputeValiHost computes the host for vali.

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) DeleteSecret

func (o *Operation) DeleteSecret(key string)

DeleteSecret deleted the secret under the given key from the operation. Calling this function is thread-safe.

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) InitializeDesiredShootClients

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

InitializeDesiredShootClients 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. In contrast to InitializeShootClients, InitializeDesiredShootClients returns an error if the discovered version via the client does not match the desired Kubernetes version from the shoot spec. This is especially useful, if the client is initialized after a rolling update of the Kube-Apiserver and you want to ensure that the discovered version matches the expected version.

func (*Operation) InitializeShootClients

func (o *Operation) InitializeShootClients(ctx context.Context) 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) IsAPIServerRunning

func (o *Operation) IsAPIServerRunning(ctx context.Context) (bool, error)

IsAPIServerRunning checks if the API server of the Shoot currently running (not scaled-down/deleted).

func (*Operation) IsShootMonitoringEnabled

func (o *Operation) IsShootMonitoringEnabled() bool

IsShootMonitoringEnabled returns true if shoot monitoring is enabled and shoot is not of purpose testing.

func (*Operation) IstioLabels

func (o *Operation) IstioLabels() map[string]string

IstioLabels contain the labels to be used for the istio ingress gateway entities.

func (*Operation) IstioLoadBalancerAnnotations

func (o *Operation) IstioLoadBalancerAnnotations() map[string]string

IstioLoadBalancerAnnotations contain the annotation to be used for the istio ingress service load balancer.

func (*Operation) IstioNamespace

IstioNamespace is the currently used namespace of the istio ingress gateway, which is responsible for the shoot cluster.

func (*Operation) IstioServiceName

func (o *Operation) IstioServiceName() string

IstioServiceName is the currently used name of the istio ingress service, which is responsible for the shoot cluster.

func (*Operation) LoadSecret

func (o *Operation) LoadSecret(key string) *corev1.Secret

LoadSecret loads the secret under the given key from the operation. Calling this function is thread-safe. Be aware that the returned pointer and the underlying secret map refer to the same secret object. If you need to modify the returned secret, copy it first and store the changes via `StoreSecret`.

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.
