Functions

func CloudProfileConfigFromCluster

func CloudProfileConfigFromCluster(cluster *controller.Cluster) (*api.CloudProfileConfig, error)

CloudProfileConfigFromCluster decodes the provider specific cloud profile configuration for a cluster

func FindAvailabilitySetByPurpose

func FindAvailabilitySetByPurpose(availabilitySets []api.AvailabilitySet, purpose api.Purpose) (*api.AvailabilitySet, error)

FindAvailabilitySetByPurpose takes a list of availability sets and tries to find the first entry whose purpose matches with the given purpose. If no such entry is found then an error will be returned.

func FindDomainCountByRegion

func FindDomainCountByRegion(domainCounts []api.DomainCount, region string) (int32, error)

FindDomainCountByRegion takes a region and the domain counts and finds the count for the given region.

func FindImageFromCloudProfile

func FindImageFromCloudProfile(cloudProfileConfig *api.CloudProfileConfig, imageName, imageVersion string, architecture *string) (*api.MachineImage, error)

FindImageFromCloudProfile takes a list of machine images, and the desired image name and version. It tries to find the image with the given name, architecture and version. If it cannot be found then an error is returned.

func FindMachineImage

func FindMachineImage(machineImages []api.MachineImage, name, version string, architecture *string) (*api.MachineImage, error)

FindMachineImage takes a list of machine images and tries to find the first entry whose name, version, architecture and zone matches with the given name, version, and zone. If no such entry is found then an error will be returned.

func FindRouteTableByPurpose

func FindRouteTableByPurpose(routeTables []api.RouteTable, purpose api.Purpose) (*api.RouteTable, error)

FindRouteTableByPurpose takes a list of route tables and tries to find the first entry whose purpose matches with the given purpose. If no such entry is found then an error will be returned.

func FindSecurityGroupByPurpose

func FindSecurityGroupByPurpose(securityGroups []api.SecurityGroup, purpose api.Purpose) (*api.SecurityGroup, error)

FindSecurityGroupByPurpose takes a list of security groups and tries to find the first entry whose purpose matches with the given purpose. If no such entry is found then an error will be returned.

func FindSubnetByPurposeAndZone

func FindSubnetByPurposeAndZone(subnets []api.Subnet, purpose api.Purpose, zone *string) (int, *api.Subnet, error)

FindSubnetByPurposeAndZone takes a list of subnets and tries to find the first entry whose purpose matches with the given purpose. Optionally, if the zone argument is not nil, the Zone field of a candidate subnet must match that value. FindSubnetByPurposeAndZone returns the index of the subnet in the array and the subnet object. If no such entry is found then an error will be returned.

func HasShootVmoAlphaAnnotation

func HasShootVmoAlphaAnnotation(shootAnnotations map[string]string) bool

HasShootVmoAlphaAnnotation determines if the passed Shoot annotations contain instruction to use VMO.

func InfrastructureConfigFromInfrastructure

func InfrastructureConfigFromInfrastructure(infra *extensionsv1alpha1.Infrastructure) (*api.InfrastructureConfig, error)

InfrastructureConfigFromInfrastructure extracts the InfrastructureConfig from the ProviderConfig section of the given Infrastructure.

func InfrastructureStatusFromRaw

func InfrastructureStatusFromRaw(raw *runtime.RawExtension) (*api.InfrastructureStatus, error)

InfrastructureStatusFromRaw extracts the InfrastructureStatus from the ProviderStatus section of the given Infrastructure.

func InfrastructureZoneToString

func InfrastructureZoneToString(zone int32) string

InfrastructureZoneToString translates the zone from the string format used in Gardener core objects to the int32 format used by the Azure provider extension.

func IsUsingSingleSubnetLayout

func IsUsingSingleSubnetLayout(config *api.InfrastructureConfig) bool

IsUsingSingleSubnetLayout returns true if the infrastructure configuration is using a network setup with a single subnet.

func IsVmoRequired

func IsVmoRequired(infrastructureStatus *api.InfrastructureStatus) bool

IsVmoRequired determines if VMO is required.
