}

Operation contains all data required to perform an operation on a Shoot 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.LastErrors is also removed.

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) DefaultIstioLabels added in v1.91.0 

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

DefaultIstioLabels contain the labels to be used for the default istio ingress gateway entities disregarding zonal affinities.

func (*Operation) DefaultIstioNamespace added in v1.91.0 

func (o *Operation) DefaultIstioNamespace() string

DefaultIstioNamespace is the default namespace of the istio ingress gateway disregarding zonal affinities of the shoot cluster.

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 

func (o *Operation) IstioNamespace() string

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.

func (*Operation) SeedVersion 

func (o *Operation) SeedVersion() string

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

func (*Operation) ShootVersion 

func (o *Operation) ShootVersion() string
