A Journey To Ephemeral Test Environments With EKS and ArgoCD
summary
Demo shows per-PR ephemeral environments that spin up on AWS EKS via Terraform and tear down automatically through Argo CD using an Argo CD ApplicationSet with PR generator and a GitHub webhook; environments use a single namespace per system with PR-number suffixes and label filtering so only PRs tagged preview label create resources. Platform team also creates full ephemeral EKS clusters from branch-based Terraform with a conditional empty-commit trigger (Terraform branch clusters); cleanup and Terraform destroy ordering, shared-state (RDBMS) strategies, and human-driven pause/resume remain the main operational challenges.
