Troubleshooting Meshery Installations
Meshery’s Preflight Checks
mesheryctl system command is executed, a series of preflight checks are run. An attempt will be made to connect to the Kubernetes cluster configured in the user’s kubeconfig as their current-context .

Setting up Meshery using Kind or Minikube
The difficulty with Minikube and Kind clusters is that they typically don’t support LoadBalancer service networking by default. Meshery UI and Meshery Broker are configured for LoadBalancer service networking by default. There are a number of solutions this overcoming this challenge. Here are a few methods:
Use the MetalLB Minikube add-on that provides load balancing.
minikube addons enable metallb
MetalLB setup: link
Use Minikube tunnel to expose services.
A simpler way to resolve this issue can be
port-forwarding. Run the following command in terminal:
kubectl port-forward service/meshery 9081:9081 -n meshery
kind, you can prefer installing MetalLB with a custom configmap.
By default, Meshery Operator is installed in all the connected clusters automatically once Meshery server detects those clusters. The operator can manually be turned off on particular cluster from the settings page.
Disabling the operator
The env variable DISABLE_OPERATOR=true can be used to signal Meshery server to not install operator in any of the clusters at any point in time after starting. While using Meshery server locally, the
make server-without-operator should be used to start Meshery in disabled operator mode.
Example of a healthy Meshery Broker server with an actively connected (subscribed) Meshery Server:
➜ ~ kubectl logs -n meshery meshery-broker-0 nats  2021/09/08 21:46:03.070952 [INF] Starting nats-server version 2.1.9  2021/09/08 21:46:03.070982 [INF] Git commit [7c76626]  2021/09/08 21:46:03.071308 [INF] Starting http monitor on 0.0.0.0:8222  2021/09/08 21:46:03.071370 [INF] Listening for client connections on 0.0.0.0:4222  2021/09/08 21:46:03.071512 [INF] Server id is NAAYJNX4LDDNXW5UE7IP7PRQR2W2JP546XSFNUWQQHN7JYY27RG47KSG  2021/09/08 21:46:03.071516 [INF] Server is ready

Meshery Remote Providers
Once Meshery is installed, the remote provider “Meshery” can be chosen from UI or by using the command
mesheryctl system login:
➜ ~ mesheryctl system login Use the arrow keys to navigate: ↓ ↑ → ← ? Select a Provider: ▸ Meshery None
If you cannot see “Meshery” Remote Provider and find such error logs in Meshery Server’s logs (
mesheryctl system logs), please make sure that Meshery Server is able to reach “https://meshery.layer5.io” in order to initialize the “Meshery” Remote Provider.
