Ensure proper file formatting by adding a newline at the end of the script. This adheres to POSIX standards and prevents potential issues with certain tools or environments.
Replaced `set -ex` with `set -e` for cleaner error output and added Helm values configuration. Ensured namespace creation doesn't fail if it already exists, and specified a custom values file for better deployment flexibility.
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.
