Operator FAQs

When is Meshery Operator deployed and when is it deleted?

As a Kubernetes custom controller, Meshery Operator is provisioned and deprovisioned when Meshery Server is connected to or disconnected from Kubernetes cluster. Meshery Server connections to Kubernetes clusters are controlled using Meshery Server clients: mesheryctl or Meshery UI. This behavior described below is consistent whether your Meshery deployment is using Docker or Kubernetes as the platform to host the Meshery deployment.

Meshery CLI mesheryctl initiates connection to Kubernetes cluster when mesheryctl system start is executed and disconnects when mesheryctl system stop is executed. This behavior is consistent whether your Meshery deployment is using Docker or Kubernetes as the platform to host the Meshery deployment.

Meshery UI Meshery UI offers more granular control over the deployment of Meshery Operator in that you can remove Meshery Operator from a Kubernetes cluster without disconnecting Meshery Server from the Kubernetes cluster. You can control the deployment of Meshery Operator using the on/off switch found in the Meshery Operator section of Settings.

Does the Meshery Operator use an SDK or framework?

Yes, Meshery Operator used the Operator SDK.
