Deployment, version control and continuous

4. The Problem

5. Deploy your
site
• Manage the way code is deployed
• Automate repetitive tasks for devs, admins when changes
go live
• Make it easy to use best practices
• Allow for flexibility, multiple deploy processes, safe testing

6. The Solution

7. The Solution
• Develop Locally
• Distributed Version Control
• Don’t keep plugins and WP core in repository
• Deploy to testing environment prior to production
• Automate build and testing

8. Continuous
Integration
• Multiple developers share code
• Several pushes per day
• Each push verified by automated build
• Avoids “integration hell”
• Teams can detect problems early

9. Workflow
• Local Development
• Central Version Control
• Continuous Integration Pipelines
• Build Script
• Dependencies
• Push to server

30. # Set Constants
INSTALL="edmund"
EMAIL="edmund.turbin@wpengine.com"
ENVIRONMENT=“production"
# Use Node 8.7.0
nvm use stable
# Disable Xdebug
rm -f /home/rof/.phpenv/versions/$(phpenv version-name)/etc/conf.d/
xdebug.ini

31. # Codeship project root is the ~/clone directory
cd ~/clone
# Set production remote and config
git config --global user.name "Codeship Deploy"
git config --global user.email "$EMAIL"
git remote add $ENVIRONMENT git@git.wpengine.com:$ENVIRONMENT/
$INSTALL.git
# Codeship initially runs a shallow fetch. This allows us to fetch
origin and get all file revisions
git fetch --unshallow || true
git fetch origin "+refs/heads/*:refs/remotes/origin/*"

32. # Run Composer to install dependencies
cd wp-content/themes/sage
composer install --prefer-source —no-interaction
# Run build tasks
npm install
bower install
gulp —production

33. # Remove unnecessary files
rm ~/clone/.gitignore
# Git Commit and Push
git add --all
git commit -m "Codeship Deployment"
git push $ENVIRONMENT HEAD:master --force

35. DemonstratioN

36. Learnings

37. Codeship
• Uses a virtual machine at time of deploy
• Has many common binaries installed, possible to install more
• Caches NPM packages
• Can be used in Debug mode which allows you to SSH into the
virtual machine and run commands until happy

38. Git Integration
• Understanding how to move files from Codeship was
difficult
• A few different attempts to make this happen
• Possible to use FTP, but Git is more streamlined and quicker
• git push — force option important - not all files in the repo
are needed in production

39. Build
• Gulp, Grunt, Webpack.js, etc. can all be run during
deployment
• Local development can use it’s own build script
• Possible to use different tasks or build scripts for each
branch
• Allows for release management - deploy different branches
to their own server environments (stage, test, production)

40. Next Steps
• Do more testing with Assertible 😁
• Remove all source files and unnecessary files like readme 😎
• Create automated rollback functionality, look at symlinks 😵
• Wishlist: Visual Regression Testing with NPM/Wraith, Backstop.js 👊
