List the Kubernetes resources managed by Config Sync in GKE cluster for the GKE cluster configs repository:

gcloud alpha anthos config sync repo describe \
    --project $TENANT_PROJECT_ID \
    --managed-resources all \
    --sync-name root-sync \
    --sync-namespace config-management-system

Wait and re-run this command above until you see "status": "SYNCED" for this RepoSync. All the managed_resources listed should have STATUS: Current as well.

List the GitHub runs for the GKE cluster configs repository:

cd ${WORK_DIR}$GKE_CONFIGS_DIR_NAME && gh run list
