How do we start if our current pipeline is a mess?

Pick one service. Add a canary with Argo Rollouts, wire an AnalysisTemplate to Prometheus error rate and latency, and make promotion automatic. Then add SBOM + Trivy + OPA gates. Measure CFR/lead time for that one service. Expand from there.

Won’t all these gates slow us down and hurt lead time?

Done right, no. Fast gates run on PRs, heavier ones run just-in-time at release. You trade a few minutes for far fewer rollbacks and incidents. The net effect is shorter lead time because rework drops.

What about legacy services that can’t run canaries?

Use traffic mirroring, shadow reads, or blue/green with smoke tests. If even that’s impossible, gate on blast radius: feature flags, rate limits, and progressive enablement by customer cohort.

How do we detect failures caused by AI-generated code?

Strengthen static rules (OPA, linters), enforce type systems, and add contract tests. We’ve seen AI hallucinate IAM permissions and off-by-one pagination — both caught by policy and PACT tests. GitPlumbers can help with vibe code cleanup and code rescue.

We use Jenkins/GitLab, not GitHub Actions. Does this still apply?

Absolutely. The tools change, the pattern doesn’t: build/test/scan/policy/canary/auto-promo with telemetry events. We’ve implemented the same gates in Jenkins Shared Libraries and GitLab CI `rules`.
