Functions

func GetWildcardCertificate

func GetWildcardCertificate(ctx context.Context, c client.Client) (*corev1.Secret, error)

GetWildcardCertificate gets the wildcard certificate for the seed's ingress domain. Nil is returned if no wildcard certificate is configured.

func RunDeleteSeedFlow

func RunDeleteSeedFlow(ctx context.Context, sc, gc kubernetes.Interface, seed *Seed, seedLogger *logrus.Entry) error

RunDeleteSeedFlow deletes certain resources from the seed cluster.

func RunReconcileSeedFlow

func RunReconcileSeedFlow(
	ctx context.Context,
	k8sGardenClient kubernetes.Interface,
	k8sSeedClient kubernetes.Interface,
	seed *Seed,
	secrets map[string]*corev1.Secret,
	imageVector imagevector.ImageVector,
	componentImageVectors imagevector.ComponentImageVectors,
	conf *config.GardenletConfiguration,
	seedLogger *logrus.Entry,
) error

RunReconcileSeedFlow bootstraps a Seed cluster and deploys various required manifests.

Types

type Builder

type Builder struct {
	// contains filtered or unexported fields
}

Builder is an object that builds Seed objects.

func NewBuilder

func NewBuilder() *Builder

NewBuilder returns a new Builder.

func (*Builder) Build

func (b *Builder) Build() (*Seed, error)

Build initializes a new Seed object.

func (*Builder) WithSeedObject

func (b *Builder) WithSeedObject(seedObject *gardencorev1beta1.Seed) *Builder

WithSeedObject sets the seedObjectFunc attribute at the Builder.

func (*Builder) WithSeedObjectFromLister

func (b *Builder) WithSeedObjectFromLister(seedLister gardencorelisters.SeedLister, seedName string) *Builder

WithSeedObjectFromLister sets the seedObjectFunc attribute at the Builder after fetching it from the given lister.

type Seed

type Seed struct {
	Info                           *gardencorev1beta1.Seed
	LoadBalancerServiceAnnotations map[string]string
}

Seed is an object containing information about a Seed cluster.

func (*Seed) CheckMinimumK8SVersion

func (s *Seed) CheckMinimumK8SVersion(seedClient kubernetes.Interface) (string, error)

CheckMinimumK8SVersion checks whether the Kubernetes version of the Seed cluster fulfills the minimal requirements.

func (*Seed) GetIngressFQDN

func (s *Seed) GetIngressFQDN(subDomain string) string

GetIngressFQDN returns the fully qualified domain name of ingress sub-resource for the Seed cluster. The end result is '<subDomain>.<shootName>.<projectName>.<seed-ingress-domain>'.

func (*Seed) GetValidVolumeSize

func (s *Seed) GetValidVolumeSize(size string) string

GetValidVolumeSize is to get a valid volume size. If the given size is smaller than the minimum volume size permitted by cloud provider on which seed cluster is running, it will return the minimum size.

func (*Seed) IngressDomain

func (s *Seed) IngressDomain() string

IngressDomain returns the ingress domain for the seed.
