Functions

func ConfigCluster 

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

ConfigCluster gets a workload cluster based on a template.

func CreateRepository 

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

CreateRepository creates a clusterctl local repository based on the e2e test config, and the returns the path to a clusterctl config file to be used for working with such repository.

func Init 

func Init(ctx context.Context, input InitInput)

Init calls clusterctl init with the list of providers defined in the local repository

func InitManagementClusterAndWatchControllerLogs 

func InitManagementClusterAndWatchControllerLogs(ctx context.Context, input InitManagementClusterAndWatchControllerLogsInput, intervals ...interface{})

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 Move 

func Move(ctx context.Context, input MoveInput)

Move moves workload clusters.

func SetCNIEnvVar deprecated added in v0.3.9 

func SetCNIEnvVar(cniManifestPath string, cniEnvVar string)

SetCNIEnvVar read CNI from cniManifestPath and sets an environmental variable that keeps CNI resources. A ClusterResourceSet can be used to apply CNI using this environmental variable.

Deprecated: Use FileTransformations in the CreateRepositoryInput to embedded CNI into cluster templates during create repository. The new approach does not uses env variables so we can avoid https://github.com/kubernetes-sigs/cluster-api/issues/3797; This func is preserved for avoiding to break users in the v0.3 series, but it is now a no-op.
