1. DOCKER The future of web apps deployment Szymon Skórczyński Schibsted Tech Polska PHPers Tricity December 15, 2014
2. ONCE UPON A TIME…
3. TODAY
4. TOP PROBLEMS Isolation from host OS and other environments Traceability of configuration changes Portability to share with colleagues and deploy easily
5. YESTERDAY’S SOLUTION Virtualization Provisioning Orchestration
6. GOOD, BUT NOT PERFECT
7. TODAY’S SOLUTION
8. KEY FACTS • written in Go in dotCloud, a PaaS provider • became open source in March 2013 • in June 2014 released stable ver. 1.0 • current version is 1.4
9. POPULARITY angular.js laravel symfony ansible vagrant chef puppet 0 10 000 20 000 30 000 40 000 2 779 3 186 8 088 8 518 9 274 13 251 17 092 32 145 Number of stars on GitHub (November 28, 2014) docker
10. PARTNERS
11. THE METAPHOR
13. HOW DOES IT WORK?
14. THE ECOSYSTEM Image is like OVF or ISO Container is a running image Repository is a place to store images
15. THE DIFFERENCE Host OS Hypervisor Guest OS Guest OS Guest OS bins/libs bins/libs bins/libs App A App A` App B Host OS Docker bins/libs bins/libs App A App A’ App B App B’ App B’ App B’ VM Docker container Docker Standard VMs
16. ADVANTAGES
17. USAGE docker pull downloads an image docker run starts a container docker commit saves changes in an image docker push uploads an image
