How to setup next.js with Kubernetes and Cert Manager!

I’ve been experimenting setting up by own development custler for Kubernetes, prompter by the need to do a series of EKS upgrades due to deprecations and forced upgrades!

I need to learn a little more about the common kubernetes tooling and play around with configuration without incurring the cost of spinning up an EKS cluster.

(If you do want to spin up an EKS cluster i highlight recommend uwing eksctl) You can bring up an entire cluster with one like of code. This includes control plane. Autoscaling group for nodes, loadbalancer and dns

You can also destroy the entire stack with one like of code too. But that’s a post for another day!

Back to my lab setup!. I’ve played around with many Kubernetes lab setups including multipass, k8s etc. For this guide i am using kind + docker..

The setup of the cluster and ingress is based on this guide

https://www.youtube.com/watch?v=72zYxSxifpM

And i highly recommend you download the githib repos from there and have a go at creating your own cluster from the guide.,

This will give you a working cluster with nginx-ingress. The cluster install with kind is again a 1 lineer (assuming you already have docker desktop setup …i am on a mac btw)

I wanted my lab setup to be accessible from the internet and secured with SSL/TLS

Cert Manager provides a set of tools to automate request process for free letsencrypt certificates for resources in your cluster,

 presented a few challenges with this … the public up i have exposed to whatsmyip tools … is not the actual public ip.

The real public ip is one that letsencrypt things is non-reoutable… So the regular http/https challenge/validation process does not work. I needed to switch the setup to use a DNS-01 challenge … which needs some setup to allow cert-manger to talk to the cloudflare API … so you need to generate some api token in your cloudflare acct and configure your cert-manager installation to use these.

🩺 Doctors have stethoscopes.
🔧 Mechanics have spanners.
👨‍💻 We developers, have Git.

Have you noticed that Git is so integral to working with code that people hardly ever include it in their tech stack or on their CV at all? The assumption is you know it already, or at least enough to get by, but do you?

Git is a Version Control System (VCS). The ubiquitous technology that enables us to store, change, and collaborate on code with others.

🚨 As a disclaimer, I would like to point out that Git is a massive topic. Git books have been written, and blog posts that could be mistaken for academic papers too. That's not what I’m going for here. 

. My aim here is to write the Git fundamentals post I wish I had when learning Git.

As developers, our daily routine revolves around reading, writing, and reviewing code. Git is arguably one of the most important tools we use. Mastering the features and functionalities Git offers is one of the best investments you can make in yourself as a developer.

If you feel I missed or should go into more detail on a specific command, let me know in the comments below. And I will update this post accordingly. 🙏
