DevOps Lens 🔍 (v2.0)
The Ultimate Real-Time "Heads-Up Display" (HUD) for Your Infrastructure.
See your Kubernetes cluster, active namespace, AWS profile, Docker containers, Terraform workspace, and Git branch at a single glance — with zero lag and interactive controls.
⚡ What's New in v2.0?
DevOps Lens v2.0 transforms from a passive 4-item list into a full-featured, interactive, real-time DevOps command center:
⚡ True Real-Time Reactive Architecture (<100ms):
- File system watchers directly monitor
~/.kube/config, ~/.aws/config, ~/.aws/credentials, and workspace .env files.
- When you switch contexts in terminal using
kubectx or kubectl config use-context, DevOps Lens updates instantly without waiting on a 30s timer!
- Real-time hooks into VS Code's Git API for instant updates on branch checkout, staging, or committing.
🛡️ Persistent Status Bar HUD:
- Always visible in VS Code's bottom status bar — no need to keep the sidebar open.
- High-Visibility Production Alert: When connected to a production Kubernetes cluster or AWS account, the status bar turns flashing RED (
errorBackground), giving you an unmissable safety warning before executing commands in your integrated terminal.
🌲 Hierarchical Tree View with Drill-Down:
- ☸️ Kubernetes: View cluster, server URL, active namespace, and expandable list of all available contexts.
- ☁️ Cloud & AWS: View active profile, region, account details, and all configured profiles from both
credentials and config. Multi-cloud support for GCP projects and Azure subscriptions!
- 🐳 Docker: Live container count, plus an expandable list of running and stopped containers with image names, uptime, and mapped ports.
- 🌿 Git: Current branch, safety indicator, dirty working tree breakdown (staged, unstaged, untracked), ahead/behind commit sync, and latest commit hash/message.
- 🌱 Terraform / OpenTofu: Active workspace detection and switcher.
🕹️ Interactive Switchers & Quick Controls:
- One-Click Context Switcher: Switch Kubernetes contexts from a searchable QuickPick palette.
- Namespace Switcher: Select from active cluster namespaces or specify a custom namespace.
- AWS Profile Switcher: Switch active profile with one click.
- Docker Actions: Inline buttons to Start, Stop, Restart, View Logs, or launch an interactive shell (
exec sh) directly in any container.
- DevOps Terminal Launcher: Spawns an integrated terminal pre-configured with
AWS_PROFILE, AWS_REGION, and your active cluster environment.
🚨 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 / profile is active?"
- "What Kubernetes namespace am I targeting?"
- "Is the Redis / PostgreSQL container actually running?"
- "Did I accidentally push directly to
main?"
🚦 The Traffic Light System
DevOps Lens keeps you safe with automatic environment detection:
| Status |
Meaning |
When it appears |
| 🟢 Green / Normal |
Safe Environment |
minikube, dev, staging, local, feature branches |
| 🔴 High Alert Red |
⚠️ PRODUCTION DETECTED |
Contexts/profiles matching prod, production, prd, live, or master-cluster |
Whenever a production environment is active:
- The Status Bar HUD switches to a prominent Red warning badge.
- Terminal launch prompts confirm you really want to open a terminal against production.
