func (o *Operation) GetShootState() *gardencorev1beta1.ShootState

GetShootState returns the shootstate resource of this Shoot in a concurrency safe way. This method should be used only for reading the data of the returned shootstate resource. The returned shootstate resource MUST NOT BE MODIFIED (except in test code) since this might interfere with other concurrent reads and writes. To properly update the shootstate resource of this Shoot use SaveGardenerResourceDataInShootState.

func (*Operation) InitializeDesiredShootClients added in v1.31.0 

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

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) 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) SaveGardenerResourceDataInShootState added in v1.32.0 

func (o *Operation) SaveGardenerResourceDataInShootState(ctx context.Context, f func(*[]gardencorev1beta1.GardenerResourceData) error) error
