Flagger end-to-end testing

The e2e testing infrastructure is powered by GitHub Actions and Kubernetes Kind.

e2e workflow

• create local Kubernetes cluster with KinD
• build Flagger container and load the image in KinD
• install the service mesh or ingress provider
• deploy Flagger
• create test namespace, workloads and load tester
• test the canary initialization (port discovery and metadata)
• test the canary release (progressive traffic shifting, headers routing, mirroring, analysis, promotion, rollback)
• test webhooks (conformance, load testing, pre/post rollout)
