## Steps

1. **Install Prometheus**

- Follow the instructions to install Prometheus using the Helm chart by Bitnami. Refer to the [Prometheus documentation](https://prometheus.io/docs/introduction/overview/) for more details.
- Ensure Prometheus is not exposed outside (i.e., it cannot be accessed directly from the internet).

2. **Verify Metrics Collection**
- Ensure Prometheus is collecting essential cluster-specific metrics, such as nodes' CPU and memory usage.
- Check the collected metrics via Prometheus web interface using `kubectl proxy` or `port-forward`.
2. **Install Exporters**
- Install necessary exporters to collect metrics from Kubernetes components.
3. **Configure Prometheus**
- Configure Prometheus to get metrics from Kubernetes components.
4. **Verify Metrics Collection**
- Ensure Prometheus is collecting essential cluster-specific metrics, such as nodes' memory usage.
- Check the collected metrics via Prometheus web interface.

## Submission

- Provide a PR with the Helm chart and configuration files for Prometheus deployment in a new repository.
- Ensure that Prometheus is installed and collecting cluster-specific metrics.
- Provide a README file documenting the Prometheus setup, including the custom dashboard.
- Provide a PR with automation of a Prometheus deployment in Kubernetes with IaC or CI/CD pipeline.
- Provide an output of `kubectl get pods` with running Prometheus.
- Include a screenshot of any metrics (e.g. node disk space usage) shown in the Prometheus web UI.
- Provide a README file documenting the Prometheus deployment and configuration.
