const FieldManager = configsync.GroupName + "/nomostest"

FieldManager is the field manager to use when creating, updating, and patching kubernetes objects with kubectl and client-go. This is used to uniquely identify the nomostest client, to enable field pruning and merging. This must be different from the field manager used by config sync, in order to allow both clients to manage different fields on the same objects.

func SetRepoSyncDependencies(nt *NT, rs client.Object) error

SetRepoSyncDependencies sets the depends-on annotation on the RepoSync for other objects managed by CentralControl (`setupCentralizedControl`).

RootSync dependencies aren't managed by another RootSync, and DelegatedControl doesn't apply with ConfigSync, so depends-on won't have any effect in those scenerios.

Takes an Object because it supports both v1alpha1 and v1beta1 RepoSyncs.

func SetupFakeSSHCreds added in v1.18.0 

func SetupFakeSSHCreds(nt *NT, rsKind string, rsRef types.NamespacedName, auth configsync.AuthType, secretName string) error

SetupFakeSSHCreds sets up the RSync Secret when needed. The Secret may or may not exist depending on the test settings.

  • If the Git provider is local, bitbucket, or gitlab, the test scaffolding uses 'ssh' as the auth type. The Secret should already exist in this case.
  • If the Git provider is CSR, it uses 'gcpserviceaccount' as the auth type. The Secret won't be created. Hence, this function creates a fake one to bypass the validation in the reconciler-manager.

This allows capturing logs even if the reconciler is deleted before the test ends. The logs will only be printed if the test has failed when the command exits. Run in an goroutine to capture logs in the background while deleting RSyncs.

func FreshTestEnv 

func FreshTestEnv(t nomostesting.NTB, opts *ntopts.New) *NT

FreshTestEnv establishes a connection to a test cluster based on the passed

options.

Marks the test as parallel. For now we have no tests which *can't* be made parallel; if we need that in the future we can make a version of this function that doesn't do this. As below keeps us from forgetting to mark tests as parallel, and unnecessarily waiting.

The following are guaranteed to be available when this function returns: 1) A connection to the Kubernetes cluster. 2) A functioning git server hosted on the cluster. 3) A fresh ACM installation.
