Let's talk about how nothing is ever truly simple in engineering and honestly, that's exactly why we get paid to solve these puzzles.
Yesterday, I picked up what seemed like a straightforward task: updating our EKS node AMIs from Amazon Linux 2 to Amazon Linux 2023.
The documentation made it look like a simple one-liner change. Classic mistake – trusting that "easy" means easy in the cloud world.
I made the changes in our dev environment, deployed successfully, and started testing. That's when things took an interesting turn.
My test was simple: create a new pod to trigger node scaling. The new node spun up as expected, then... got stuck. Cue the troubleshooting session that every DevOps engineer knows too well.
After digging into the logs, I discovered kubelet was failing to start. Further investigation revealed the culprit: bootstrap.sh had been removed from AL2023, and our configuration was still trying to use it. Amazon Linux 2023 now uses nodeadm instead, a completely different approach to node bootstrapping.
So there I was, diving deep into nodeadm documentation, learning a new tool, and redesigning our node initialization process.
The Real Point
This is the essence of DevOps and platform engineering. What started as a "simple AMI update" quickly became a journey through:
Terraform configuration updates
EKS cluster management
EC2 instance troubleshooting
Linux system administration
Kubernetes kubelet debugging
Learning an entirely new bootstrapping tool
The Lesson
This wasn't a failure, it was just a normal day. In our field, every "simple" task is potentially a rabbit hole of learning opportunities. The key is embracing the complexity, staying curious, and remembering that this constant evolution and problem-solving is exactly what makes our work both challenging and rewarding.
The ability to quickly switch context between different tools, debug across multiple layers of the stack, and adapt to changing technologies isn't just a nice-to-have skill, it's the core of what we do.
What's your latest "simple" task that turned into an unexpected learning adventure? I'd love to hear about it in the comments.
