Scaling Progressive Delivery at EarnIn: Leveraging Linkerd for Advanced Deployments With Gateway API
Talkat Linkerd Day Europe 2025 · on Tuesday, 2025-04-01· at 13:35· Level 3 | ICC Capital Suite 14-16·
summary
EarnIn migrates nearly 600 microservices to Argo CD + Argo Rollouts, uses Linkerd + Gateway API for traffic splitting and mirroring, and integrates DataDog via analysis templates to automate canary and blue/green decisions. A three‑step zero‑downtime migration references existing Deployments from Rollout CRDs, runs Rollouts and Deployments in parallel, then deprecates the Deployment. Platform adds a self‑service Helm values UI so developers configure custom steps and thresholds; automated rollbacks trigger after defined latency or error increases (demo showed rollback after three failed analyses).
