Docker: From Zero to Hero
- 1. DOCKER: FROM ZERO TO HERO
- 2. Topics of Presentation • Why Docker? • Difference between Virtual machine and Docker • What is Docker • Docker Architecture • Docker Installation • Docker Commands • Docker Compose • DockerFile • Communication between containers • Swarm
- 3. Why Docker? • Development team on same page in term of environment • Development, QA and Production sync up • Local to Production easy deployment and scaling • Build & Deploy, fast & better
- 4. Difference between Virtual machine and Docker • Containers are an abstraction at the app layer that packages code and dependencies together. • Virtual machines (VMs) are an abstraction of physical hardware turning one server into many servers.
- 5. What is Docker “Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package.” “ Docker Provides the version control of development/production environment.”
- 6. Docker Architecture • Docker daemon • Docker client • Docker registries • Docker objects – Images – Containers
- 7. Docker Installation • Docker for Windows/Mac • Toolbox for Windows/Mac – Docker CLI client for running Docker Engine to create images and containers – Docker Machine so you can run Docker Engine commands from Windows terminals – Docker Compose for running the docker- compose command – Kitematic, the Docker GUI – the Docker QuickStart shell preconfigured for a Docker command-line environment – Oracle VM VirtualBox
- 8. Cont… Windows Toolbox URL: https://docs.docker.com/toolbox/toolbox_insta ll_windows/ Mac Toolbox URL: https://docs.docker.com/toolbox/toolbox_insta ll_mac/ Docker for Windows: https://www.docker.com/docker-windows Docker for Mac: https://www.docker.com/docker-mac
- 10. Docker Commands • Docker Machine: – docker-machine ls – docker-machine start [MACHINE_NAME] – docker-machine stop [MACHINE_NAME] – docker-machine env [MACHINE_NAME] – docker-machine ip [MACHINE_NAME] – docker-machine status[MACHINE_NAME]
- 11. Cont… • Docker Images VS Docker Container : • Docker Images – docker pull [IMAGE_NAME] //pulls the image from hub.docker.com – docker images // list all images – docker rmi [IMAGE_NAME] // remove image – Example • docker pull nginx:latest • docker pull mysql:latest • docker pull php:7.1
- 12. Cont… • Docker Container: – docker container ps // list running containers – docker container ps –a // list all containers – docker rm –f [CONTIANER_NAME] // remove container – Example • docker container run –name nginxServer -p 80:80 nginx • docker container run –name nginxServer -p 80:80 –v $(pwd):/usr/share/nginx/html nginx
- 13. Cont… • Set up nginx, PHP 7 and Mysql. • Run some commands on created Containers: – docker container top – docker container inspect – docker container stats
- 14. ANY QUESTIONS?
- 15. Docker commands • Docker Compose: – docker-compose build – docker-compose up – docker-compose down – docker-compose logs – docker-compose ps – docker-compose stop – docker-compose start – docker-compose rm
- 16. Cont… • Set up nginx, PHP 7 and Mysql.
- 17. Docker File • Docker File is used to customize the image
- 18. ANY QUESTIONS?
- 19. Communication between containers • docker network ls • docker network inspect [NETWORK_NAME] • docker network create [NETWORK_NAME] • docker network rm [NETWORK_NAME]
- 21. THANK YOU
Editor's Notes
- Because the Docker Engine daemon uses Linux-specific kernel features, you can’t run Docker Engine natively on Windows. Instead, you must use the Docker Machine command, docker-machine, to create and attach to a small Linux VM on your machine. This VM hosts Docker Engine for you on your Windows system. https://docs.docker.com/toolbox/toolbox_install_windows/
- This is another option for an Overview slides using transitions.
- Docker pull [IMAGE_NAME] commands pulls the image from hub.docker.com.
- Docker pull [IMAGE_NAME] commands pulls the image from hub.docker.com.
