Istio configuration is defined by a set of multiple objects and object types and is susceptible to operator error or architecture oversight. The getmesh config-validate command performs validations of the cluster’s current config and yaml manifests that are not applied yet.
The command invokes a series of validations using external sources such as upstream Istio validations, Kiali libraries, and Tetrate Istio Distro custom configuration checks. A combined validation output is then sent to the stdout. Custom configuration validation checks are actively being added all the time.
