Hello

- I'm mose, SysAdmin at Faria Systems

- Devops duties
= helping developers to (ab)use the infrastructure

- 4 SaaS apps in production, 5 more apps in development
all ruby on rails based applications,
and hopefully some node.js and go for new apps

Docker

- https://www.docker.com

- High level API for managing containers
Written in Go

- Created by DotCloud, a PaaS company

march 2013 - First open source release
june 2014 - First stable release

Docker Containers

- similar to BSD jail
- run processes in isolation
- protects the host OS
- no supervisor
- each container has an IP
- created from an incremental image

https://docker.com/whatisdocker

Docker Ecosystem

- Docker is very popular in coders community
very active contributions in open source

- official and community images
https://registry.hub.docker.com/

- a lot of solutions developed on the top of docker
11 209 matches for 'docker' on github
https://github.com/search?q=docker

Docker for Self-Hosted PaaS

Dokku = Docker + Heroku

- Docker-powered mini-Heroku in around 100 lines of Bash

- smart combination of
- git (custom server, with deployment hook)
- docker (building in containers)
- buildstep (provisionning the stack)
- sshcommand (user api for non-privileged operations)
- pluginhook (for dokku plugins)
- nginx (proxy for vhosts management)

- easy one-line install on any linux host

- various extensions for extending the dokku server
https://github.com/progrium/dokku/wiki/Plugins

Recorded live demo

- not so live, it's a recording

First we need a server, let's create one ...

dokku  tugboat

tugboat add-key NAME # Upload an ssh public key.
tugboat authorize # Authorize a DigitalOcean account with tugboat
tugboat create NAME # Create a droplet.
tugboat destroy FUZZY_NAME # Destroy a droplet

tugboat password-reset FUZZY_NAME # Reset root password
tugboat rebuild FUZZY_NAME IMAGE_NAME # Rebuild a droplet.
tugboat regions # Show regions
tugboat resize FUZZY_NAME -s, --size=N # Resize a droplet
tugboat restart FUZZY_NAME # Restart a droplet
tugboat sizes # Show available droplet sizes
tugboat snapshot SNAPSHOT_NAME FUZZY_NAME [OPTIONS] # Queue a snapshot of the droplet.
tugboat ssh FUZZY_NAME # SSH into a droplet
