Introduces custom `metallb.yaml` Helm values with node selectors and tolerations targeting specific nodes. Renames and adjusts MetalLB resource file, removing unused IPs. Updates installation script to apply the new Helm values and handle namespace creation idempotently.
Switched the ACME server to Let's Encrypt production for certificate issuance. Added a new ClusterIssuer resource for staging to support testing without hitting rate limits.
This commit includes Helm-based installation scripts for MetalLB, Traefik, Cert-Manager, and External DNS, along with their necessary configurations. Updates to cert-manager YAML ensure production-ready naming and namespace adjustments. These changes aim to streamline the deployment and management of Kubernetes services with simplified automation.
Introduce a `ClusterIssuer` resource for cert-manager to enable Let's Encrypt integration with Traefik. Add an MIT license for the project and clarify the purpose of the repository in the README.
