Functions

func CleanupKubernetesFirewalls

func CleanupKubernetesFirewalls(ctx context.Context, client gcpclient.ComputeClient, 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.ComputeClient, 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(ctx context.Context, tf terraformer.Terraformer, config *api.InfrastructureConfig, createSA bool) (*apiv1alpha1.InfrastructureStatus, error)

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

func ComputeTerraformerTemplateValues

func ComputeTerraformerTemplateValues(
	infra *extensionsv1alpha1.Infrastructure,
	account *gcp.ServiceAccount,
	config *api.InfrastructureConfig,
	podCIDR *string,
	createSA bool,
) (map[string]interface{}, error)

ComputeTerraformerTemplateValues computes the values for the GCP Terraformer chart.

func CreateFirewallListOpts

func CreateFirewallListOpts(network, shootSeedNamespace string) gcpclient.FirewallListOpts

CreateFirewallListOpts creates the FirewallListOpts options.

func CreateRoutesListOpts

func CreateRoutesListOpts(network, shootSeedNamespace string) gcpclient.RouteListOpts

CreateRoutesListOpts creates the RouteListOpts options.

func DeleteFirewalls

func DeleteFirewalls(ctx context.Context, client gcpclient.ComputeClient, firewalls []*compute.Firewall) 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.
