2. Are you developer and do development locally?

3. Development Stack or Pre-packaged Environments
Traditional packaged Development Stack over Linux / Windows / Mac
Apache
MySQL
PHP
Java / tomcat
Ruby/Rails
Tools:
XAMPP
MAMP
WAMP
Add On software:
Apache solr
PhpMyAdmin
Node JS

4. Difficulties: in Pre-packaged Environments
Real time environments in Dev / Stage / Prod are different
Different Versions
Different modules and plugins
Example: PHP YAML Extensions or Spicy Library
Single Stack for Multiple projects while each project or initiatives have different purpose and goals
It works on my system not on production
Hard to understand server configurations for developers
Cloning Project or Building Project from Scratch on Local vs Dev/Stage/Prod

5. Where to adopt over Pre-packaged Environments
Virtual Machines (VM) ?
What is VM:
A virtual machine is a software computer that, like a physical computer, runs an operating system and applications
The virtual machine is comprised of a set of specification and configuration files and is backed by the physical resources of a host
Every virtual machine has virtual devices that provide the same functionality as physical hardware and have additional benefits in terms of portability, manageability, and security
VM based Developments
It matches with Prod configuration of server or application stack
Configure stack as Code configuration
You can Spun, destroy / suspend / Rebuild

6. What to know in VM? Vagrant:
Vagrant provides the same, easy workflow regardless of your role as a developer, operator, or designer
It is declarative configuration file which describes all your software requirements, packages, operating system configuration, users, and more
Aims to mirror production environments by providing the same operating system, packages, users, and configurations
You can still have flexibility to use their favourite editor, IDE, and browser
Integrates with your existing configuration management tooling like Chef, Puppet, Ansible, or Salt
works on Mac, Linux, Windows
Remote development environments force users to give up their favourite editors and programs

7. What to know in VM? Ansible:
It is powerful automation engine that makes system and app simple to deploy
No complex scripting

8. What solution we have for Drupal?
Drupal VM:
local Drupal development, built with Vagrant and Ansible
Support Mac OS, Linux, and Windows
Support multiple utilities like : Apache solr , PHP, Node JS etc.
Utilities can be enabled or disabled
Link:
Documentation:
Overriding is easy to suite developers requirements
default.config.yml : default configurations
Config.yml : to override
Vagrant.config.yml : Environment specific overrides. When you run Drupal VM through Vagrant, the environment will be set to vagrant and this file is loaded when available example: prod.config.yml
Local.config.yml : Local development overrides

9. Drupal VM: How it works? Drupal VM: Start: vagrant status
Run: vagrant up
Provision: vagrant provision
Save: vagrant suspend
Start again: vagrant resume
Stop: vagrant halt
Destroy: vagrant destroy
Manage: vagrant global-status
Help: vagrant help

10. Drupal VM Demo magic of vagrant up and provision
DrupalVM demo for Drupal 8 with composer
DrupalVM demo for Drupal 7 with make file
DrupalVM demo for Custom make file and Drupal project

11. Docker?
Docker is the only container platform to build, secure and manage the widest array of applications from development to production both on premises and in the cloud
Supports Linux / Windows / Mac
Provides agility to move platform configuration
Enables portability of infrastructure
Deliver application stack securely and consistent in nature
Optimise use of infrastructure resources

12. Drupal4Docker
Docker4Drupal is a set of Docker images optimized for Drupal. Use docker- compose.yml
Docker4Drupal is designed to be used for local development
Link:
Documentation:
Allow to run Vanial Drupal 7 / Drupal 8
Allow to mount your own codebase
Run containers: docker-compose up –d
Stop containers: docker-compose stop

13. docker4Drupal Demo Run containers: docker-compose up –d
Stop containers: docker-compose stop
