Digest #179: Vibe Coding Hype, DevOps Exercises, Terraform+MCP, Windows inside a Docker

AI coding isn’t a silver bullet, Rust beats microservices for simplicity, Kubernetes adds cost-saving features, AWS beginners get easy tips, and you can even host your own AI with Docker.

Welcome to this week’s edition of the DevOps Bulletin!

“Vibe coding” with AI sounds fun, but it’s risky. InfluxData dropped microservices and rebuilt as a Rust monolith for speed and fewer bugs. SigNoz sped up log searches by 99.5% with a new indexing trick, and Lakera showed how a shared doc can make innovative IDEs run hidden malware. Elsewhere: Netflix tracks network traffic with eBPF, old VPNs and GitOps is coming to Linux, AWS sandboxes can still leak secrets, event ordering in distributed systems stays messy, and Signadot argues devs should have their own test environments.

On the tutorial front: DevOps Daily dropped ten hands-on labs, Bottlefire turned Docker images into Firecracker microVMs, and Kubernetes 1.33 added trafficDistribution. You’ll also see guides on self-hosting LLMs with Ollama, Terraform power patterns, and AWS cost-saver basics.

Our open-source spotlight: Keycloak for IAM, Kconnect to find clusters, DBeaver as a universal DB client, Plural for enterprise Kubernetes management, Dockurr/Windows to run Windows in Docker, and term.everything, which teases GUI apps in your terminal.

All this and more in this week’s DevOps Bulletin, don’t miss out!

Are shared environments slowing your team down? 🐢

When developers have to share a single testing environment, releases stall, and the "blame game" begins. Signadot fixes this by giving every engineer a personal, on-demand environment - without duplicating the entire stack. This allows your team to test in parallel, eliminate contention, and ship faster.

Read how to fix your staging bottleneck.
