Killer Drupal 8 Workflow for Pantheon

This project is meant to be forked and used as an easy-to-get-going start state for an awesome dev workflow that includes:

Canonical upstream repo on GitHub
Local development and tooling with Lando
Hosting on Pantheon
Automatic manual QA environments via Pantheon multi-dev
Merge-to-master deploy-to-pantheon-dev pipeline
Automated code linting, unit testing and behat testing with Travis

What You'll Need

Before you kick off you'll need to make sure you have a few things:

A GitHub account, ideally with your SSH key(s) added
A Pantheon account with a Machine Token
A Travis CI account
Lando installed
Git installed*
(Optional) ZenHub for Kanban style issue management in GitHub

It is also definitely worth reading about the upstream starter kit.

If you are using lando you can forgo the git installation (this is potentially useful for Windows devs) by uncommenting git in the tooling section of your .lando.yml. If you do this you'll need to run lando git instead of git for all the examples below.

Getting Started

1. Setup Pantheon

Login to Pantheon and create a new D8 project through the user interface. After naming your site and completing the spin up visit your site and go through the Drupal installation process to get your DB dialed in.

2. Setup GitHub

Visit this start state on GitHub and fork the project to the org or account of your choosing. Then git clone the repo and cd into it.

git clone https://github.com/lando/lando-pantheon-ci-workflow-example mysite
cd mysite

3. Setup Local Lando and Connect to Pantheon

Let's start by spinning up a local copy of our Pantheon site with Lando.

This should spin up the services to run your app (eg php, nginx, mariabdb, redis, solr, varnish) and the tools you need to start development (eg terminus, drush, composer, drupal console). This will install a bunch of deps the first time you run it but when it is done you should end up with some URLs you can use to visit your local site.

# Connect to pantheon
cd /path/to/my/repo
lando init --recipe=pantheon

# Start the app
lando start

# Pull the database and files
# Run lando pull -- -h for options
land pull

If you are interested in tweaking your setup check out the comments in your app's .lando.yml. Or you can augment your Lando spin up with additional services or tools by checking out the advanced Lando docs.

4. Setup Travis CI

You will want to start by doing Steps 1 and 2 in the Travis getting started docs. We already have a pre-baked .travis.yml file for you so you don't need to worry about that unless you want to tweak it.

Finally, set your Pantheon machine token and site machine name as environment variables via the Travis UI.

PANTHEON_MACHINE_TOKEN=TOKEN_YOU_GENERATED
PANTHEON_SITE_NAME=PANTHEON_SITE_NAME

Trying Things Out

Let's go through a GitHub flow example!

This is a trivial example which deploys all merges into the master branch to the Pantheon dev environment.

1. Set up a topic branch

# Go into the repo
cd /path/to/my/github/repo

# Checkout master and get the latest and greatest
git checkout master
git pull origin master

# Spin up a well named topic branch eg ISSUE_NUMBER-DESCRIPTION
git checkout -b 1-fixes-that-thing

2. Do the dev, commit and push the codes

# Do some awesome dev

# Git commit with a message that matches the issue number
git add -A
git commit -m "#1: Describes what i did"

# Push the branch to GitHub
git push origin 1-fixes-that-thing

Check out the Lando Reference section below for some tips on how to run tests before you push. This can save a lot of time and reduce the potential shame you feel for failing the automated QA

3. Open a PR and do manual and automated testing

Begin by opening a pull request. This will trigger the spin up of a QA environment for manual testing and a Travis build for automated testing.

Here is an example PR with:

4. Deploy

When you are statisifed with the above, and any additional QA steps like manual code review you can merge the pull request. This will deploy the feature to production.

Lando Reference

You should definitely check out the Lando Pantheon docs for a full sweep on its capabilities but here are some helpers for this particular config. YOU PROBABLY WANT TO LANDO START YOUR APP BEFORE YOU DO MOST OF THESE THINGS.

Unless otherwise indicated these should all be run from your repo root (eg the directory that contains the .lando.yml for your site).
