CI/CD GitOps Pipeline Lab (Interactive)
Parallelize CI stages along their dependency graph, then gate a canary through 5 to 100 percent on live error and latency. Compare push versus pull GitOps security and step a canary forward only while 5xx rate and P99 latency stay inside thresholds.
CI Lead Time & Progressive Delivery Gate
Parallelize the dependency DAG of your CI stages, then step a canary through 5→25→50→100% behind Prometheus gates.

Canary traffic split
ArgoCD runs in-cluster and pulls the desired manifest repo every 3 minutes: no inbound firewall port, no CI-held kubeconfig, and manual cluster edits are auto-reconciled back to Git — drift is impossible to hide.
How It Works Under the Hood
Continuous Integration runs lint, tests, SAST, CVE scans and a signed multi-stage build; arranging those stages so independent work runs concurrently collapses lead time, and flaky tests quietly multiply the number of runs until green. GitOps then splits deployment into push versus pull: a Jenkins runner that holds a production kubeconfig is a wide attack surface, whereas ArgoCD runs in-cluster, pulls desired state from Git, and keeps cluster credentials inside the private network. Progressive delivery routes a 5 percent canary, promotes through 25, 50 and 100 percent only while Prometheus 5xx and P99 latency stay within gates, and auto-rolls-back on breach.
Core Architectural Principles
- Pull-based GitOps keeps cluster admin credentials inside the cluster; the in-cluster operator reconciles from Git.
- Canary promotion steps forward only while HTTP 5xx stays under 0.1 percent and P99 delta under 10 percent.
- Feature flags decouple deployment (code on servers) from release (visibility to users).
Argue why pull-based GitOps beats push: the cluster pulls from Git so CI runners never hold root kubeconfig and expose no inbound firewall ports, and manual drift is auto-reconciled. Describe progressive delivery with concrete gates: five percent canary, verify Prometheus 5xx under 0.1 percent and P99 delta under ten percent over a window, then step to full traffic or auto-rollback. Separating deployment from release via feature flags shows production maturity.
Trunk-based GitOps with canary gates accelerates safe delivery, but demands solid metrics, traffic routing and flaky-test discipline.
