Build & test once, deploy anywhere

Vday 2016Zsolt Molnar

Introduction / Use-case

• Myself: 12 sysadmin + 3 years DevOps XP• Software development company needs to ship

code to customers• Requirements: – Provide OVA/OVF images for Vmware ESXi/KVM– Provide AMI images for AWS– Build a CI/CD pipeline for both– Enable easy updates without full image re-import

1. The aim of the presentation is mainly to show how can you stitch together different tools to get an automated build and test pipeline

2. The presentation at some places may not follow general Docker recommendation/guidelines for simplification

Etc… Cron?

Tools

• Jenkins – CI “orchestration”• VirtualBox – VM on local machine• Vagrant – build OVA/OVF• Docker-mac • Docker distribution (v2 registry) – local builds• Packer – build AMI• ECR – container registry for AMI build• S3 – store container bundles for rolling updates
