inform-syncer-configs

This is a simple diagnostic and demo that exercises the mailboxwatch package to make and use an informer on SyncerConfig objects.

Aside from the usual, the command line arguments are as follows.

$ go run ./cmd/inform-syncer-configs -h
Usage of inform-syncer-configs:
...
      --all-cluster string               The name of the kubeconfig cluster to use for access to the SyncerConfig objects in all clusters
      --all-context string               The name of the kubeconfig context to use for access to the SyncerConfig objects in all clusters (default "system:admin")
      --all-kubeconfig string            Path to the kubeconfig file to use for access to the SyncerConfig objects in all clusters
      --all-user string                  The name of the kubeconfig user to use for access to the SyncerConfig objects in all clusters
...
      --espw-cluster string              The name of the kubeconfig cluster to use for access to the edge service provider workspace
      --espw-context string              The name of the kubeconfig context to use for access to the edge service provider workspace
      --espw-kubeconfig string           Path to the kubeconfig file to use for access to the edge service provider workspace
      --espw-user string                 The name of the kubeconfig user to use for access to the edge service provider workspace
...
pflag: help requested
exit status 2

This command requires two kube client configurations. One points at the edge service provider workspace (ESPW) with authorization to list and watch Workspace objects (the mailbox WOrkspaces) in that workspace. The other client config points at the server base with authorization to list and watch SyncerConfig objects from all clusters.

Currently the output is very simple logging.

Following is an example of its usage.

$ kubectl ws root:espw
Current workspace is "root:espw".
