Functions

func CleanupKubernetesFirewalls

func CleanupKubernetesFirewalls(ctx context.Context, client gcpclient.Interface, projectID, network, shootSeedNamespace string) error

CleanupKubernetesFirewalls lists all Kubernetes firewall rules and then deletes them one after another.

If a deletion fails, this method returns immediately with the encountered error.

func CleanupKubernetesRoutes

func CleanupKubernetesRoutes(ctx context.Context, client gcpclient.Interface, projectID, network, shootSeedNamespace string) error

CleanupKubernetesRoutes lists all Kubernetes route rules and then deletes them one after another.

If a deletion fails, this method returns immediately with the encountered error.

func ComputeStatus

func ComputeStatus(tf *terraformer.Terraformer, config *gcpv1alpha1.InfrastructureConfig) (*gcpv1alpha1.InfrastructureStatus, error)

ComputeStatus computes the status based on the Terraformer and the given InfrastructureConfig.

func ComputeTerraformerChartValues

func ComputeTerraformerChartValues(
	infra *extensionsv1alpha1.Infrastructure,
	account *internal.ServiceAccount,
	config *gcpv1alpha1.InfrastructureConfig,
	cluster *controller.Cluster,
) map[string]interface{}

ComputeTerraformerChartValues computes the values for the GCP Terraformer chart.

func DeleteFirewalls

func DeleteFirewalls(ctx context.Context, client gcpclient.Interface, projectID string, firewalls []string) error

DeleteFirewalls deletes the firewalls with the given names in the given project.

If a deletion fails, it immediately returns the error of that deletion.

func DeleteRoutes

func DeleteRoutes(ctx context.Context, client gcpclient.Interface, projectID string, routes []string) error

DeleteRoutes deletes the route entries with the given names in the given project.

If a deletion fails, it immediately returns the error of that deletion.

func GetServiceAccountFromInfrastructure

func GetServiceAccountFromInfrastructure(ctx context.Context, c client.Client, config *extensionsv1alpha1.Infrastructure) (*internal.ServiceAccount, error)

GetServiceAccountFromInfrastructure retrieves the ServiceAccount from the Secret referenced in the given Infrastructure.

func ListKubernetesFirewalls

func ListKubernetesFirewalls(ctx context.Context, client gcpclient.Interface, projectID, network, shootSeedNamespace string) ([]string, error)

ListKubernetesFirewalls lists all firewalls that are in the given network and for the given shoot and have the KubernetesFirewallNamePrefix.

func ListKubernetesRoutes

func ListKubernetesRoutes(ctx context.Context, client gcpclient.Interface, projectID, network, shootSeedNamespace string) ([]string, error)

ListKubernetesRoutes returns a list of all routes within the shoot network which have the shoot's seed namespace as prefix.

func StatusFromTerraformState

func StatusFromTerraformState(state *TerraformState) *gcpv1alpha1.InfrastructureStatus

StatusFromTerraformState computes an InfrastructureStatus from the given Terraform variables.

Types
