Method initMeshConfiguration

pilot/pkg/bootstrap/mesh.go:48–58

initMeshConfiguration creates the mesh in the pilotConfig from the input arguments. Original/default behavior: - use the mounted file, if it exists. - use istio-REVISION if k8s is enabled - fallback to default If the 'SHARED_MESH_CONFIG' env is set (experimental feature in 1.10): - if a file exist,

(args *PilotArgs, fileWatcher filewatcher.FileWatcher)

// - if istio-REVISION exists, will be used, even if the file is present.
// - the SHARED_MESH_CONFIG config map will also be loaded and merged.
func (s *Server) initMeshConfiguration(args *PilotArgs, fileWatcher filewatcher.FileWatcher) {
	log.Infof("initializing mesh configuration %v", args.MeshConfigFile)
	col := s.getMeshConfiguration(args, fileWatcher)
	col.AsCollection().WaitUntilSynced(s.internalStop)
	s.environment.Watcher = meshwatcher.ConfigAdapter(col)
