So I was messing around with this thing called Stefan Ki, you know, trying to get my Kubernetes game on point. I’d heard about it, seemed cool, but I needed to actually try it out myself. Here’s how it went down.
First off, I grabbed the latest release from their GitHub page. It was a simple download, nothing fancy. Then I extracted the archive, which gave me the `stefan-ki` binary. I moved this bad boy over to my `/usr/local/bin` directory, so I could run it from anywhere on my system. Easy peasy.
Next up, I needed a Kubernetes cluster to play with. Since I didn’t have one just lying around, I fired up Minikube. It’s this neat little tool that lets you run a single-node cluster locally. One command, `minikube start`, and boom, I had a cluster ready to go.
With my cluster up and running, I decided to deploy a sample application. I used a simple Nginx deployment, just to keep things straightforward. I wrote a basic YAML file describing the deployment, then applied it using `kubectl apply -f *`. My Nginx was now running happily in my cluster.
Now for the fun part – testing out Stefan Ki. I wanted to see how it handled progressive rollouts, you know, those fancy canary deployments. I created a Canary object using Stefan Ki. It was pretty simple, just another YAML file where I specified my deployment, the target traffic percentage, and some metrics to monitor.
I applied the Canary object with `kubectl apply -f *`. Then I watched as Stefan Ki did its thing. It gradually increased the traffic to the new version of my Nginx deployment, all while keeping an eye on the metrics I’d defined. I could see the traffic shifting in real-time using `kubectl stefan-ki get canaries`. It was pretty slick.
After messing around with different settings and scenarios, I felt like I had a good handle on Stefan Ki. It’s a powerful tool for managing deployments in Kubernetes.
- Downloaded Stefan Ki from GitHub
- Set up a local Kubernetes cluster with Minikube
- Deployed a sample Nginx application
- Created and applied a Canary object
- Observed Stefan Ki’s progressive rollout in action
Overall, my little experiment with Stefan Ki was a success. I learned a lot about canary deployments and how to manage them effectively. If you’re working with Kubernetes, I’d definitely recommend giving it a try. It just makes things easier, ya know? Like, way less headache than doing it all manually.
