5. 5 Why Continuous Delivery Platform ? • tight integration into Zalando infrastructure e.g. ◦ Docker registry ◦ IAM ◦ Zalando cluster setup • one file to configure tasks ◦ no extra configuration via UI, plugins, configurations etc. • managing 100+ Jenkins masters plus more agents is quite some effort • unique build environment • quick worker feedback • worker easy scaling up and down • transparent credential
6. 6 Architecture sketch Continuous Delivery Platform delivery.yaml descriptor file Docker Registry
7. 7 Continuous Delivery Platform - simplified source code management system Controller code change trigger Builder Proxy Docker Registry Worker VMs token injection schedules and monitors tasks source code checkout task execution image upload
8. 8 Main Concepts • proxy with user transparent credentials ◦ untrusted build workers without secrets ◦ transparent credential injection for artifact upload and source access in build workers • deep integration ◦ GHE, Zalando Sonarqube, Zalenium, Zalando Kubernetes • “The Second Best Interface is The One You Already Use” - Joao Santos • scm-source.json generation out of the box • all configuration in delivery.yaml file
9. 9 Way of Working • team does informed decisions ◦ programming language ◦ proxy technology • weekly presentations (recorded for the whole company) • weekly stakeholder alignment • monitoring from the very beginning
