How are you deploying your pods to Kubernetes? You are about to say helm, aren't you? You ended up on this page probably because you are looking for an alternative to helm. Stop googling and start reading, here I am going to explain what works for me. A while ago I was looking for a tool with the following features:
Kubernetes simplifies management of containerised applications and promotes automation of all the aspects of a deployment. It can do even more if combined with third parties components that's what we are going to do today, we are going to use cert-manager and letsencrypt to generate TLS certificates automatically.
An ingress controller is component in the kubernetes cluster that manages the traffic coming into the cluster. Through ingress configurations you can define the rules to access the containers in you pod. For more info refer to the official documentation.
