Validate the current Istio configurations in your cluster just like ‘istioctl analyze’. Inspect all namespaces by default. If the <file/directory> is specified, we analyze the effect of applying these yaml files against the current cluster.
getmesh config-validate <file/directory>... [flags]
Examples
# validating a local manifest against the current cluster
$ getmesh config-validate my-app.yaml another-app.yaml
# validating local manifests in a directory against the current cluster in a specific namespace
$ getmesh config-validate -n bookinfo my-manifest-dir/
