🔐 Scenario: Updating the Grafana Admin Password in Kubernetes

If you’re running Grafana in a Kubernetes cluster and need to reset the admin password, follow these simple steps.

🚀 Steps to Update the Admin Password

1) Set the Namespace: Define the namespace where Grafana is running. 2) Identify the Pod Name: Use kubectl to fetch the Grafana pod name dynamically. 3) Reset the Password: Execute a command inside the Grafana pod to reset the admin password.

# Define the namespace where Grafana is running
NAMESPACE=monitoring

# Get the Grafana pod name dynamically
POD_NAME=$(kubectl get pods -n "${NAMESPACE}" -o=name | grep grafana | cut -f2 -d/)

# Reset the admin password using the Grafana CLI
kubectl exec -it -n "${NAMESPACE}" "${POD_NAME}" -- /bin/sh -c "/usr/share/grafana/bin/grafana-cli admin reset-admin-password ${POD_NAME}"

Note: For this example, the new password will be set to the Grafana pod name.

🛠 Troubleshooting

• Problem: The pod name is not detected. Solution: Ensure Grafana is running and the NAMESPACE variable is correct.

• Problem: The Grafana CLI is not found. Solution: Verify that the Grafana CLI is installed inside the container and accessible at /usr/share/grafana/bin/.

🎉 Congratulations!

You’ve successfully updated the Grafana admin password in Kubernetes. 🚀
