Download as PPTX, PDF1 like104 views
The document provides an introduction to Docker and guides users on how to dockerize web applications using nginx, Redis, and PHP-FPM. It covers concepts such as containers vs. virtual machines, security, and includes multiple lab exercises demonstrating Docker usage, including Dockerfile creation and Docker Compose. It summarizes essential Docker commands and tips for effective usage.

Docker intro workshop: Dockerize your PHP app
- 1. Docker: intro workshop Dockerize your Web App: Nginx + Redis +PHP-FPM
- 2. Index ● What’s Docker ● Pros ● Containers vs VMs ● API ● Concept: Containers vs Images ● Security ● Workshop ● Docker-compose ● Summary ● Tips
- 3. What’s “that” whale called Docker? Origin: LXC Run multiple isolated Linux systems on the same host
- 4. Time is money friend! 12 apps * 700MB = 8.5GB
- 7. VS
- 8. ● Hypervisor emulates hardware y kernel-> isolate ● Docker containers are implemented by the host kernel itself ● Hypervisor out the box vs Seccomp (https://docs.docker.com/engine/security/seccomp/) ● Kernel exploit ● Resource starvation ● Container breakout ● In practice: ○ Another POV-> deployment ○ ¿kernel exploit? Security
- 10. container = running image Image: class Container: instance 1 image -> * Containers Senderismo...¿wtf?
- 11. Hello World docker run hello-world
- 12. Dockerfile
- 14. Do I need Docker? Give it an opportunity,for example Redis.
- 15. Lab 1 - nginx https://github.com/avcconti/dockerize-web-app
- 16. Lab 2 - nginx + PHP
- 17. Lab 3 - nginx + PHP + Redis
- 18. Lab 4 - nginx (entrypoint)+ PHP + Redis
- 19. entrypoint CMD=> /bin/sh -c ‘/usr/sbin/php-fpm --nodaemonize’ exec "$@" -> /bin/sh -c ‘$ && /usr/sbin/php-fpm --nodaemonize’
- 20. Oh yeah baby, this is awesome, but...
- 22. Docker-compose.yml + 1 comando= done Lab 5 - Docker-compose
- 25. Summary ● Dockerfile ● docker image ● docker container ● docker network ● docker volume (--from) ● docker-compose
- 26. Cleaning ● docker system df [-v] ● docker container stop $(docker container ls -a -q) ● docker system prune [-a]
- 27. Tips ● Files ○ dockerfile ○ .dockerignore ○ docker-compose.yml ○ .env ● ENV variables ● Stateless apps ● Dockerfile instructions order: heaviest at top
