Pipeline with multiple stages, each stage can have multiple jobs
Stage 1: Preparing
Stage 2: Linters and Tests
Stage 3: Building an image
Stage 4: On master: Deploying to Kubernetes into a stage
namespace
Stage 5: On master: Testing if stage works
Stage 6: On tag: Tag the docker image
Stage 7: On tag: Deploying to Kubernetes into a prod
namespace
Stage 8: On tag: Testing if prod works
In detail
Stage 1: Preparing
Only do slow operations once and cache and re-use results
Stage 2: Linters and Tests
Add linters for everything
Unit tests
Integration tests

Resources and configures itself to route incoming traffic to the correct running and healthy pods
cert-manager
Cert-manager listens on Ingress Resources and if they need TLS,
requests a certificate from LetsEncrypt
external-dns
External-DNS listens on Ingress Resources and creates DNS entries
Prometheus
Kubernetes and Node metrics are automatically included
Kubernetes and Node alerts are automatically included
Kubernetes and Node dashboards are automatically included
Scraping targets can be automatically discovered
