5. What is Docker ?
“Docker containers wrap up a piece of
software in a complete filesystem that contains
everything it needs to run: code, runtime,
system tools, system libraries – anything you
can install on a server. This guarantees that it
will always run the same, regardless of the
environment it is running in.”
https://www.docker.com/what-docker

6. Once upon a time…. VMs!

7. A few concepts here…
•Docker images
•Docker containers
•Docker volumes
•Docker networks

8. Your system is already containerised!
• Namespaces: limits what you can use. (netns, user,
pid etc…)
• Cgroups: limits how much you can use (memory,
CPU, IO, Network, devices)
• Copy on write storage
• And much more :)
What’s behind a container ?

9. OSS Ecosystem
• Docker Engine
• Docker Machine
• Docker Swarm
• Docker Compose
• Docker Registry (and the public Docker hub)
• Notary
• Interlock
• Something new released a few minutes ago

10. Docker can run PHP programs too!

11. From now on,
we will have a few demos
May the force be with me

12. A simple PHP container
docker run -it
-p 8080:8080
php:7.0.6-alpine
sh -c 'mkdir /code;
echo "<?php phpinfo();"
> /code/index.php;
php -S 0.0.0.0:8080 -t /code'

13. A custom Dockerfile for this
FROM php:7.0.6-alpine
ADD code/ /code
EXPOSE 8080
CMD ["php", "-S", "0.0.0.0:8080",
"-t", "/code"]

14. Ok, but, I want a Webserver, a
database, a key value store and a
message broker!

15. One container per service!
We already need two of them,
PHP-FPM and NGINX

16. Orchestrating container
dependencies manually is painful

17. docker-compose
TO THE RESCUE!

18. version: '2'
services:
nginx:
image: nginx:latest
ports:
- "80:80"
links:
- php
volumes_from:
- php
php:
build: php:7.0.6-fpm-alpine
expose:
- "9000"
volumes:
- ./:/var/www/application
A simple docker-compose.yml

19. DEMO TIME!
