The crux of the issue is that adapters cannot be deployed when you are running 
locally.
Here, locally means using you ran server using make server.
If you’d like to connect to any of the adapters then you’d have to run them locally too. That is by running make run into the respective directory of adapter (eg GitHub - meshery/meshery-istio: Meshery adapter for Istio).
If you’d like to deploy/undeploy adapter then you’d first have to deploy Meshery either in Kubernetes or Docker.
Then based on your platform Meshery Adapters can also be deployed using that deploy/undeploy button in the UI.
