Step-by-Step Guide: Installing and Using Glasskube

Prerequisites:
Kubernetes cluster: You'll need a running Kubernetes cluster.
kubectl: The kubectl command-line tool is required for interacting with the cluster.
Docker: Docker is needed to build and deploy the Glasskube application.

Steps:

Download and install Glasskube:

You can download the latest version of Glasskube from the official GitHub repository: https://github.com/glasskube/glasskube
Extract the downloaded archive.

Build and deploy the Glasskube application:

Navigate to the Glasskube directory and build the application using Docker:
```
 docker build -t glasskube .
```
Deploy the Glasskube application to your Kubernetes cluster using kubectl:
```
 kubectl apply -f deployment.yaml
```
(Replace deployment.yaml with the appropriate deployment file provided in the Glasskube repository).

Access the Glasskube dashboard:

Once the deployment is complete, you can access the Glasskube dashboard by visiting the specified URL in your browser (usually http://localhost:3000).

Explore Glasskube features:

Navigate through the dashboard to explore features like cluster resource visualization, monitoring, and alerting.
Configure dashboards and alerts to meet your specific monitoring needs.

Example code snippets:

Deployment configuration:

   apiVersion: apps/v1
   kind: Deployment
   metadata:
     name: glasskube
   spec:
     replicas: 1
     selector:
       matchLabels:
         app: glasskube

         labels:
           app: glasskube
       spec:
         containers:
         - name: glasskube
           image: glasskube:latest
           ports:
