Ephemeral Environments with Pulumi and EKS vcluster

TLDR DevOps breaks down how Pulumi pairs with EKS and vcluster to spin up ephemeral environments. The setup is meant to cut down on resource waste while keeping testing isolated.

The post walks through the infrastructure-as-code side of things — defining clusters, namespaces, and workloads with Pulumi instead of hand-wrangling YAML. The idea is that each dev gets their own lightweight vcluster inside a shared EKS cluster, so they can push changes without breaking the main app.

It's a devops play. Not a consumer-facing product. Not a story about small businesses or founders. It's engineering infrastructure for teams already writing code at scale. No pricing, no customer names, no stats. Just the how.

The TLDR newsletter itself is free, daily, and aimed at developers who want to stay current without reading every blog post. Dan writes it. It's a side hustle that keeps the dev community fed.

Why this matters for us: Most devops tools are built for big tech teams. The rest of us are still figuring out how to run a CI/CD pipeline without a dedicated ops budget — and that gap only widens when the tools keep getting more complex.
