You are sir, the reason why I am watching work related videos at holidays. Really interesting, informational and cool edited content. Keep it up!

@minhthinhhuynhle9103 2 жыл бұрын

Just to clarify, every EVERY videos from Mr.Dempers are clear and intuitive even for both newbie and intermediate k8s users. I like the way you edit the video, your speech are continuous and delay exactly on time. Your voice are clear, the illustration from images are straightforward. Step by step guiding are totally insane for such low-level users. It worth every second watching your channel even on holiday. Thanks to your project. I jumped to K8s Intermediate level really fast.

MetalLB works well for LoadBalacner services on on-site clusters (not sure about in KinD though...) The other method if ingresses are involved is to use the "cert-manager.io/cluster-issuer" or "cert-manager.io/issuer" annotations. With that, cert-manager will create the Certificate object as well.

Thank you for your great tutorial. It was very educational and helped me to learn a lot of topics. However I do have a problem with installing and using cert-manager with the GKE autopilot cluster. The cert manager installs but the webhook doesn't work. Tried with Helm too. Not avail. Is there anything to recommend, please?

@Palex1990 7 ай бұрын

Very nice tutorial thank you. I am wondering if I can use it... How to use the cert-manager when you have an external load balancer? I have a three node rancher cluster with an external nginx load balancer? It's not possible since cert-manager does not expose the secrets right?

Is this also going to work in a situation where port 80 and 443 is forwarded to my Synology NAS? my Kubernetes cluster is running on a server. In the past, I spun up an Nginx container to secure my environment with a certificate from let's encrypt, but it never worked because the port was forwarded to my NAS.
