func (*ServiceRuntime) WaitForDependencies added in v4.53.0 

func (s *ServiceRuntime) WaitForDependencies(mainResource string, dependencies ...string) bool

WaitForDependencies takes two arguments, the name of the main resource, which should be deployed after the dependencies. It also takes a list of names for objects to depend on. It does NOT deploy any objects, but check for their existence. If true is returned it is safe to continue with adding your main object to the desired resources. If the main resource already exists in the observed state it will always return true.

func (s *ServiceRuntime) WaitForDependenciesWithConnectionDetails(mainResource string, objectCDMap map[string][]string) (bool, error)

WaitForDependenciesWithConnectionDetails does the same as WaitForDependencies but additionally also checks the given list of fields against the available connection details. objectCDMap should contain a map where the key is the name of the dependeny and the string slice the necessary connection detail fields.
