Panel: Argo Vs Flagger: Progressive Delivery with Linkerd
summary
Compares Argo Rollouts and Flagger using Linkerd for canary, blue/green and A/B progressive delivery, showing concrete tradeoffs: Linkerd provides cluster‑wide mTLS, lightweight Rust proxy, Prometheus metrics and fine‑grained traffic control enabling 1% to 100% progression and automated rollbacks; Argo Rollouts is a per‑cluster controller with a Rollout CRD, UI and tight Argo CD integration and models canaries as separate deployments; Flagger uses a Canary CRD, works with many ingress/meshes, boots in about 5 minutes by creating a shadow deployment that complicates day‑two reasoning; the two can be combined with caveats.
