Docker as a Multitool: DevOps with Docker at Azure Bootcamp Linz 2017

Usersnap

Docker is an open source tool for running isolated containers on Linux making the deployment of apps inside containers faster. Docker creates portable, self-sufficient containers from any application. Since Docker's first release in 2013, containers are getting fancier (again). And since containers are particularly popular for web apps, Martin Sereinig shows us how Usersnap uses Docker.

DEVOPS WITH DOCKER
DEVOPS WITH DOCKER DOCKER 101 ▸ Docker ▸ Really lightweight VMs ▸ Images are classes, Containers are instances ▸ docker-compose ▸ Orchestrate multiple containers ▸ Configure through one file
DEVOPS WITH DOCKER (DEVOPS) REALITY IN A STARTUP ENVIRONMENT ▸ not a lot of people ▸ everybody wears a lot of hats ▸ time is the most valuable resource ▸ there is no IT department
DEVOPS WITH DOCKER OPS WITH DOCKER: GOALS ▸ Be able to run it all ▸ … reliably ▸ … and keep it running ▸ Fast and easy provisioning ▸ Easy scaling ▸ Save Time
DEVOPS WITH DOCKER OPS WITH DOCKER: IMPLEMENTATION ▸ Nothing but the core competency ▸ Use what you know ▸ Docker host machines run on standard Linux ▸ Docker to build frontend application ▸ Deploy containers for the backend ▸ We’re on AWS, but it does not really matter!
DEVOPS WITH DOCKER ❌ ❌ ❌ ❌
DEVOPS WITH DOCKER CONTINUOUS INTEGRATION ▸ Codeship connected to repository ▸ Every push triggers: linting, testing, … ▸ Push in master triggers staging build + deploy ▸ Push with release tag triggers release build ▸ Manual deploy
DEVOPS WITH DOCKER SCALING ▸ Vertically ▸ Horizontally ▸ Provision new application servers with Ansible ▸ Deploy to new application server ▸ Add to load balancer ▸ Very quick. Could even be automated through API calls
DEVOPS WITH DOCKER
DEVOPS WITH DOCKER DOCKER IN DEVELOPMENT: PROBLEM ▸ Remember the diagram from before? ▸ Dev environment as similar to production as possible ▸ Different versions of software, configuration locations, … ▸ People run different operating systems
DEVOPS WITH DOCKER DOCKER IN DEVELOPMENT: SOLUTIONS ▸ Use a different environment than in production? ▸ Have a development server with everything installed? ▸ Run everything locally?
DEVOPS WITH DOCKER DOCKER IN DEVELOPMENT ▸ Install Docker ▸ Install git ▸ git pull ▸ docker-compose up ▸ ☕ ▸ Start working
RANDOM DOCKER
"I SUPPOSE IT IS TEMPTING, IF THE ONLY TOOL YOU HAVE IS A HAMMER, TO TREAT EVERYTHING AS IF IT WERE A NAIL." Abraham H. Maslow RANDOM DOCKER
RANDOM DOCKER USERSNAP BLOG ▸ Wordpress, MySQL, Optimus Cache Prime, Backup ▸ Dockerized! ▸ Data stored through volume mount
RANDOM DOCKER APPLICATION DEMO PROJECT ▸ Did I mention we are hiring? ▸ Applicants make a little demo project ▸ Can choose their tools ▸ Different people will look at the project ▸ Dockerized!
RANDOM DOCKER ANALYTICS SCRIPTS ▸ People do reporting, etc. ▸ Not necessarily developers ▸ Dockerized!
RANDOM DOCKER WORDPRESS PLUGIN ▸ Wordpress Plugin to integrate Usersnap ▸ Dockerized! ▸ MySQL, Wordpress stock images ▸ Plugin is linked into plugin folder
RANDOM DOCKER BUILDING OUR HOMEPAGE ▸ Static page build with Hugo ▸ Again: Not only developers make changes ▸ Dockerized!
RANDOM DOCKER RESISTANCE IS FUTILE!
LESSONS LEARNED
DEVELOPMENT ENVIRONMENT IS A VERY GOOD START. LESSONS LEARNED
ALWAYS USE DOCKER-COMPOSE! LESSONS LEARNED
USE DOCKER VOLUMES TO LINK FILES AND PERSIST DATA. LESSONS LEARNED
BASH (OR WHATEVER INTERACTIVE COMMAND) INTO A RUNNING CONTAINER LESSONS LEARNED
USE A DOCKER-COMPOSE .ENV FILE TO SET A COMPOSE PROJECT NAME LESSONS LEARNED
MAC AND WINDOWS: MEH. LESSONS LEARNED (OR IS IT?)
