Great job on meeting the core requirements of the task! 🎉 Your configuration files are well-structured and mostly correct. There are a few minor issues to address, such as correcting the typo in the HPA configuration and verifying probe paths. Additionally, consider the security implications of certain settings and ensure the mateapp namespace exists. These improvements will enhance the robustness and security of your setup. Keep up the good work! 🚀

Setting nodefs.available to "0%" might lead to issues as it effectively disables eviction based on available node filesystem space. Consider setting a more reasonable threshold to prevent potential node failures due to disk space exhaustion.

The certSANs value my-hostname should be replaced with an actual hostname or IP address that the API server will be accessed from. This is important for ensuring proper certificate validation.

The node label ingress-ready=true is applied to the control-plane node. Ensure that this is intentional, as typically, ingress controllers are deployed on worker nodes.

Ensure that the mateapp namespace exists in your cluster before applying this deployment. If it doesn't exist, you will need to create it first.

The liveness probe path api/health should be verified to ensure it correctly reflects the health check endpoint of your application. If the path is incorrect, the application might be restarted unnecessarily.

Similarly, verify the readiness probe path api/ready to ensure it matches the readiness check endpoint of your application. Incorrect paths can lead to the application being marked as not ready.

There is a typo in the field name avrageUtilization. It should be averageUtilization. This typo will cause the HPA configuration to be invalid and should be corrected.

The argument --kubelet-insecure-tls is used to skip TLS verification when connecting to the kubelet. This can be a security risk as it allows for potential man-in-the-middle attacks. Consider using a secure connection with proper certificates if possible.

The insecureSkipTLSVerify: true setting is a security risk as it disables TLS verification for the APIService. It's recommended to use valid certificates and set this to false to ensure secure communication.
