This document discusses how Docker and Pharo are used at a company to deploy and scale a mobility service application for Airbus across multiple servers. Key points: - Docker is used to package and deploy Pharo applications and their dependencies. Docker Swarm manages distributing containers across servers for scaling. - Ansible scripts orchestrate starting Docker containers for the Pharo applications, database, message queue and other services on Linux servers. - Monitoring of the distributed application and servers is done through Grafana dashboards and alerts. - The application has over 100 Pharo images running across three Docker Swarms for development, testing and production environments.

- 2. We are… Pierre Chanson Marcus Denker Norbert Hartl
- 3. • Founded in 2009 (10 Year party next year!) • 13 people in Cologne (Germany) and Ho Chi Minh City (Vietnam) • iPhone, Android, Web, Backend. Pharo! • You might know the german Call A Bike or Flinkster Car Sharing.
- 4. This presentation • Server infrastructure • Application deployment, Monitoring • Workflow: following one commit step-by-step
- 5. The project • Big project: mobility service for Airbus • Need for scale: +10k users in a few hours timeframe • Need not to be killed by complexity

- 16. What is Docker? • Think about it as a Smalltalk image, but for Linux • Docker Image is build from a description (Dockerfile) • Then we can run it (once or multiple times)
- 17. Wassup ? (every 10 mins) Alright, pull run tests docker-compose build docker-compose push

- 20. Ansible: Orchestration • We need to start lots of stuff (Pharo, Webserver, MessageQueue, Database…) • Ansible is a way to script typical unix admin things • Both used to setup the Linux machines and to start Docker

- 23. Docker: Swarm • We want to run on multiple machines • Swarm allows to run “services” which scale to multiple docker containers • Manages Distribution, restart…

- 25. Monitoring • Lots of machines (virtual and real) • Lot of different software (database, web, message queue, lots Pharo images) • How do we look at it?
- 26. Monitoring • Grafana • Dashboard • Alarms: Get Notifications via Mail and in Slack • Docker images provide data via REST API • Pharo GC, Zinc Requests

- 30. And that x 3 • We have 3 Swarms: • Alpha (development) • Beta (testing) • Production • And you can run the whole setup on your laptop, too! +100 Pharo images overall in our cluster
- 31. Much more… Pharo Library for Docker Swarm (work in progress)
- 32. Much more… • Lots of in-house libs • Visualise Docker Swarm with Roassal (first work) • Docker Health Check from Pharo • Server for and Pharo app for Fuel Stack Traces • DockerEngine + OpenAPI Tell us what you want to see at the Show Us Your Project !
