Vagrant and Docker
- 1. Vagrant and Docker Portable Development Environments
- 2. Who we are Feroj Bepari Senior Software Engineer Nascenia Ltd. feroj@nascenia.com Samiul Hoque Senior Software Engineer Nascenia Ltd. samiul@nascenia.com 2
- 3. Development environments made easy Create and configure lightweight, reproducible, and portable development environments. 3
- 4. What Vagrant is ❏Development environment setup tool ❏Focused on automation ❏Lowers development environment setup time ❏Development - Production parity ❏No more “Works on my machine” excuses 4
- 5. Why Vagrant ❏Easy to configure ❏Reproducible and portable ❏Single consistent workflow ❏Industry-standard tools integration 5
- 6. Benefits of Vagrant ❏Isolate dependencies and their configuration ❏A single disposable, consistent environment ❏Creates a single Vagrantfile for a project and share with other developer/designers ❏Others just need to run vagrant up and everything is installed and configured for work. 6
- 7. Installation ❏ Download and Install VirtualBox https://www.virtualbox.org/wiki/Downloads ❏ Download and Install Vagrant http://www.vagrantup.com/downloads 7
- 8. Let us create a VM ❏ Ubuntu Server 14.04 (trusty64) ❏ Git ❏ LAMP Stack ❏ Composer ❏ Node ❏ Redis ❏ Memcached ❏ Beanstalkd ❏ Supervisor ❏ PHPMyAdmin ❏ The Web Application: ➭ A laravel installation ➭ A mysql database for the application ➭ Queue configuration 8
- 9. Initializing Vagrant 9 ❏mkdir vagrant-test ❏cd vagrant-test ❏laravel new testvagrant A fresh laravel will be installed in testvagrant directory. ❏vagrant init A new Vagrantfile will be placed in the vagrant-test directory. ❏vagrant up
- 10. Updating Host OS Names Hosts File 10
- 11. Access the Sample Vagrant Project The sample file is accessible at https://github.com/samiuln/vagrant-test 11
- 13. An open platform for distributed applications for developers and sysadmins Build, Ship, Run 13
- 14. What Docker is ❏High level ❏ A lightweight VM ❏ Own process space ❏ Own network interface ❏ Can run stuff as root 14 ❏Low level ❏ Container = isolated processes ❏ Share kernel with host ❏ <<application container>>
- 15. Why Docker ❏Run everywhere ❏ Regardless of kernel version ❏ Regardless of host distro ❏ Physical or virtual, cloud or not ❏ Container and host architecture must match... 15 ❏Run anything ❏ If it can run on the host, it can run in the container ❏ If it can run on a Linux kernel, it can run
- 17. Why Container are Lightweight 17
- 18. Install Docker ❏Go to https://docs.docker.com/engine/installation/ ❏sudo docker run hello-world 18
- 19. Docker Hub ❏More than 100,000 public images ❏Push your image to public repository ❏Use anywhere, any time :) ❏https://hub.docker.com/ 19
- 20. Demo ❏Run mysql docker image from Docker hub ❏ docker run --name wordpressdb -e MYSQL_ROOT_PASSWORD=password -e MYSQL_DATABASE=wordpress -d mysql:5.7 ❏Pull wordpress from docker hub ❏ docker pull wordpress ❏Run wordpress container from local ❏ docker run -e WORDPRESS_DB_PASSWORD=password -d --name wordpress --link wordpressdb:mysql wordpress 20
- 21. Demo (contd.) ❏Show all docker container ❏ docker ps, docker ps -a ❏Inspect wordpress configuration ❏ docker inspect wordpress 21
- 22. Demo (contd.) ❏Where is my SOURCE CODE? :( ❏ docker run -e WORDPRESS_DB_PASSWORD=password -d --name wordpress --link wordpressdb:mysql -p 127.0.0.2:8080:80 -v "$PWD/":/var/www/html wordpress ❏ TIRED typing command? ❏ Docker has a solution :) 22

Editor's Notes
- Samiul
- Samiul Vagrant is a tool for building complete development environments. With an easy-to-use workflow and focus on automation, Vagrant lowers development environment setup time, increases development/production parity, and makes the "works on my machine" excuse a relic of the past.
- Samiul Vagrant provides easy to configure, reproducible, and portable work environments built on top of industry-standard technology and controlled by a single consistent workflow to help maximize the productivity and flexibility of you and your team. To achieve its magic, Vagrant stands on the shoulders of giants. Machines are provisioned on top of VirtualBox, VMware, AWS, or any other provider. Then, industry-standard provisioning tools such as shell scripts, Chef, or Puppet, can be used to automatically install and configure software on the machine.
- Samiul isolate dependencies and their configuration within a single disposable, consistent environment, without sacrificing any of the tools you're used to working with (editors, browsers, debuggers, etc.) creates a single Vagrantfile, you just need to vagrant up and everything is installed and configured for you to work.
- Samiul
- Feroj - 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.

- Go to the universal docker installation page, which is super easy for even non tech people :P Run ‘hello-world’ container, from docker hub
