DevOps Lens 🔍
The "Heads-Up Display" for your infrastructure — see your Kubernetes context, AWS profile, Docker status, and Git branch at a glance.
🚨 The Problem Every DevOps Engineer Knows
"Wait... am I connected to production?"
You stop coding. Open a terminal. Type kubectl config current-context. Squint at the output. Breathe a sigh of relief (or panic). Go back to coding.
Time lost: 15+ seconds — and that cognitive interruption costs you even more.
Now multiply that by every time you wonder:
- "Which AWS account am I using?"
- "Is Docker even running?"
- "Did I forget to switch off
main?"
✅ The Solution: A One-Second Safety Check
With DevOps Lens, you just glance at the sidebar.
🔴 Red icon? You're on production. Step carefully.
🟢 Green icon? You're safe. Code freely.
Time lost: 1 second.
🚦 The Traffic Light System
DevOps Lens uses a simple, intuitive traffic light to protect you:
| Status |
Meaning |
When it appears |
| 🟢 Green |
Safe environment |
minikube, dev, staging, local, etc. |
| 🔴 Red |
⚠️ PRODUCTION |
Any context containing prod, production, prd, or live |
You'll know instantly if you're about to run that kubectl delete on the wrong cluster.
