Functions

func AdjustConfigPathForBinary added in v1.3.0 

func AdjustConfigPathForBinary(clusterctlBinaryPath, clusterctlConfigPath string) string

AdjustConfigPathForBinary adjusts the clusterctlConfigPath in case the clusterctl version v1.3.

func ApplyClusterTemplateAndWait 

func ApplyClusterTemplateAndWait(ctx context.Context, input ApplyClusterTemplateAndWaitInput, result *ApplyClusterTemplateAndWaitResult)

ApplyClusterTemplateAndWait gets a cluster template using clusterctl, and waits for the cluster to be ready. Important! this method assumes the cluster uses a KubeadmControlPlane and MachineDeployments.

func ApplyCustomClusterTemplateAndWait added in v1.5.0 

func ApplyCustomClusterTemplateAndWait(ctx context.Context, input ApplyCustomClusterTemplateAndWaitInput, result *ApplyCustomClusterTemplateAndWaitResult)

func ConfigCluster 

func ConfigCluster(ctx context.Context, input ConfigClusterInput) []byte

ConfigCluster gets a workload cluster based on a template.

func ConfigClusterWithBinary 

func ConfigClusterWithBinary(_ context.Context, clusterctlBinaryPath string, input ConfigClusterInput) []byte

ConfigClusterWithBinary uses clusterctl binary to run config cluster or generate cluster. NOTE: This func detects the clusterctl version and uses config cluster or generate cluster accordingly. We can drop the detection when we don't have to support clusterctl v0.3.x anymore.

func CopyAndAmendClusterctlConfig added in v1.7.0 

func CopyAndAmendClusterctlConfig(_ context.Context, input CopyAndAmendClusterctlConfigInput) error

func CreateRepository 

func CreateRepository(ctx context.Context, input CreateRepositoryInput) string

func Delete added in v1.1.0 

func Delete(ctx context.Context, input DeleteInput)

Delete calls clusterctl delete --all.

func Init 

func Init(ctx context.Context, input InitInput)

InitManagementClusterAndWatchControllerLogs initializes a management using clusterctl and setup watches for controller logs. Important: Considering we want to support test suites using existing clusters, clusterctl init is executed only in case there are no provider controllers in the cluster; but controller logs watchers are created regardless of the pre-existing providers.

func InitWithBinary
