USAgov 2021

A revamped USA.gov site using Drupal 9 and Cloud Foundry

Table of contents

Prerequisites

Before starting the project setup install/download the following:

Note: To download these tools, you must have administrator rights. If you do not have them and you're using a GSA computer, you can request admin rights here.

Setting Up the Project

Initialization

Follow these steps when you first start working on the project, or anytime you want to reset your local development environment:

Note: Please wait until each command finishes before running the next. Expect long wait times. We recommend keeping your laptop (if you're using one) plugged in during this setup.

  1. Open a terminal and go to the project folder.

  2. Run the these commands in the terminal:

    bin/init
    docker compose up
    

    Wait until messages stop scrolling by; the final message will probably be a message from node saying "Starting 'watch-sass' ..."

  3. Open your browser and go to localhost (no port number needed). Initially, this will show an empty Drupal site. Note: You should see logging messages in the terminal as the sote loads. This may take a minute.

Database Setup

Once you finish the previous section, follow these steps to set up your USAgov database:

  1. Download the latest SQL database available from our Google Drive.

  2. Unzip the file and move the .sql file directly into the root of your USAgov project folder.

  3. Open a new terminal and go to your USAgov project folder.

  4. Run one of the following commands to populate the database from the SQL file you downloaded:

    If you sql file is titled usagov.sql, run this command:

    bin/db-update
    

    If the file is not titled usagov.sql, run this command:

    bin/db-update usagov_other.sql
    

    Note: Expect a message saying there's no need to update the mariadb database.

  5. Reload the localhost page in your browser. You should now see the beta.usa.gov home page.

back to top

Media files Setup

Once you finish the previous section, you may not see the images on the site, please follow these steps to set up the media files:

  1. Download the latest ZIP file available from our Google Drive.

  2. Go to the root of your USAgov project folder in your IDE or preferred file manager system in your computer.

  3. Locate the following folder: s3/local/cms/public.

  4. Unzip the downloaded ZIP file and replace the current s3/local/cms/public folder with the one you just unzipped.

  5. Reload the localhost page in your browser. You should now see the images on the site.

Access the Drupal Portal

To access the Drupal Portal to make any additional configurations, you will need to follow a few more steps.

  1. Generate a new URL to access your administrator account.

    bin/drush uli
    
  2. The unique URL will be in some form of

    http://default/user/reset/1/123456789/ai6u4-iY1LgZFUjwVW2uXjh5jblqgsfUHGFS_U/login

    Replace the the default portion with localhost. It should now be in the form: http://localhost/user/reset/1/123456789/ai6u4-iY1LgZFUjwVW2uXjh5jblqgsfUHGFS_U/login

    Note: This is a ONE-TIME login.

  3. Adjust your credentials accordingly, so that you have a valid username/password combination to use for logging in to the Drupal portal going forward. You will need a valid username/password combination to provide to the Cypress tests, as well as for logging in to the Drupal portal directly.

    Navigate to Admin -> People, find your user account, and edit it to add a password.

    Log out as root, and log in with your own user account.

Note: You will need to repeat these steps any time you re-load the database from a backup.

Automated tests setup (cypress)

We use Cypress. Note that we use only the Cypress App, not Cypress Cloud!

  • Tests run in the cypress Docker container.
  • The tests themselves are in the automated_tests/e2e-cypress directory.
  • Twig debugging will break some of the tests! Turn it off before running tests to get the most accurate results.

Minimal setup for headless tests

  1. Supply Drupal credentials for the automated tests: Edit the file env.local.cypress. Supply a valid Drupal user name and password for cypressCmsUser and cypressCmsPass.

  2. Run docker compose up to (re-)create the cypress container with the new environment variables.

  3. Run bin/cypress-ssh to open a shell in the cypress container

    You can run npx cypress run --spec cypress/e2e to run the entire test suite, or specify a smaller subset like cypress/e2e/functional.

    The Report will be written to automated_tests/e2e-cypress/cypress/reports/html/index.html and you can open it in your web browser by navigating to that file and opening it. Cypress will report that it wrote the tests to /app/e2e-cypress/cypress/reports/html/index.html, which is the location of that file in the volume mounted to the cypress docker container.

Note: The first time you run bin/init, it will create the env.local.cypress file by copying env.default.cypress. The default cypressBaseUrl in that file should be correct for running tests against your local dev site.

Setup for running Cypress interactively

You will need an X11 server on your computer, so that cypress can open a web browser in an X window you can interact with.

On MacOS, install XQuartz

This setup is based on information from these guides:

This assumes you're using homebrew.

  1. Check whether XQuartz is already installed:

    brew info xquartz
    

    If XQuartz is already installed, continue with step 3. If you wind up changing any XQuartz settings, you should restart XQuartz, but you don't need to reboot.

  2. If XQuartz is not installed, install it:

    brew install xquartz
    

    XQuartz will start up immediately.

  3. From the XQuartz Settings menu, select Security and check (enable) Allow connections from network clients.

    The "network client" you're enabling this for is the virtual machine running in your cypress container.

  4. Reboot your computer. (You need to reboot once after installing XQuartz. Thereafter, when you change your XQuartz settings you need to restart XQuartz, but not reboot.)

Proceed to Allow cypress to open an X window

On Windows ... TODO

Allow cypress to open an X window

You'll need your local IP address. You're looking for the IP address of your machine on your local network, so it will probably start with 10. or 192.168.. This command will probably work:

LOCAL_IP=$(ifconfig en0 | grep inet | awk '$1=="inet" {print $2}')
echo $LOCAL_IP

On a Mac, you can also find your IP Address in your Network Settings, or by holding down the Option key and clicking on the Wifi icon in your menu bar.

Note that this address will change if you change networks, or if you disconnect and reconnect to the network

  1. Allow connections from your IP address to open X windows:

    xhost $LOCAL_IP
    

    You should see a message like 10.0.0.200 being added to access control list. (If you see no DISPLAY is set, that might mean you didn't reboot after installing XQuartz.)

  2. Edit env.local.cypress. The DISPLAY variable should be set to your local IP address with :0 after it, for example, DISPLAY=10.0.0.200:0

  3. Run docker compose up to (re-)create the cypress container with the new environment variable. Alternatively, you can set the DISPLAY variable in the shell you get by running bin/cypress-ssh.

How to re-run the website

There are two ways in which you can do this:

Using the terminal

  1. Open Docker Desktop.

  2. Open your USAgov project in your IDE.

  3. Open a new terminal in your IDE.

  4. Make sure you are located in the usagov-2021 folder.

  5. Type the following command in your terminal:

    docker compose up
    

Using Docker Desktop

  1. Open Docker Desktop.

  2. Click on the section Containers located on the left panel.

Theme Lint Guidelines

If you make any changes to the scss or js files, make sure to check for linting errors nd resolve them before submitting a pull request.

bin/npm run lint

Project Restart/Reset

Sometimes, Docker problems arise after an upgrade and a more complete restart is needed. After closing down and destroying the existing containers, networks, and volumes the procedure is the same as the full project setup.

Docker Cleanup

docker compose down
docker system prune

Refer to Full Project Setup section above to continue the setup.

Update Database

Safe development database dumps are kept in Google Drive. You can download and import a SQL database from https://drive.google.com/drive/folders/1zVDr7dxzIa3tPsdxCb0FOXNvIFz96dNx?usp=sharing.

Copy down the database you want by checking the date in the filename. For example: usagov_01_14_2022.sql.zip. Unzip the file. It should be renamed to just usagov.sql. Place that uncompressed .sql file into the root of your repo. Then call the bin/db-update script. This could take over 10 mßinutes, so be patient. No messages are good. It will return you to the command prompt when it is done.

  1. Download and Unzip the respective zip file
  2. Move usagov.sql to the root of your project directory
  3. Run bin/db-update (or bin/db-update usagov_other.sql if the file is not titled usagov.sql)

Starting on a new ticket

When starting new work you may have to reset your database to a good starting point and make sure the current Drupal config is reflected in the site.

# Switch to stable starting point
git checkout dev
git fetch
git pull


# Reset db
bin/db-update
bin/drupal-update
docker compose up


# Start new work
git checkout -b USAGOV-###-new-feature-branch

back to top

Continuing Work

If you are returning to work on an existing feature branch you will need to make sure to update it with the latest changes from a fresh dev branch. It is also good practice to update any branch you are working on frequently.

# switch out of feature branch and into dev branch
git checkout dev
git fetch
git pull


# switch back into feature branch
git checkout USAGOV-###-existing-feature-branch
git merge dev
docker compose up

Tickets and Branching

A branch name must be named after its associated Jira ticket. This is required for some parts of the automation to work. A Branch name must at minumum be USAGOV-###. You may optionally append a short lowercase dash-separated description to make things easier for humans to read.

ex: USAGOV-123-short-ticket-name

If a ticket name is too long, you may shorten or even exclude the title, only the USAGOV-### prefix is required.

We are using a git script to automatically add the current branch name to all commits in an effort to make all commit messages effortlessly reflect the task being worked on. This helps with automation.

cp .git.commit-msg .git/hooks/commit-msg

Single Item Config Export

If you have lots of junk or temporary config changes in your current database you may opt to only pick out the individual configs you know are needed. You can see the full list of available changes on the main Config Synchronize screen (/admin/config/development/configuration). Once you determine which config changes will be needed you can go to the Export > Single Item (/admin/config/development/configuration/single/export). There you can see and export just that one item.

USAgovTheme

The USAgov theme is a subtheme of the USWDS_base theme. This project's default start procedure (docker compose up) will start a container to automatically watch for changes and recompile the theme as needed.

The theme can be manually built at any time through gulp's build task. Any other gulp task can be triggered the same way.

# Rebuild theme
bin/npm run build

Any changes made to the node modules needed for building the theme will require a re-install of the node_modules before build.

# Reinstall node modules
bin/npm install
bin/npm run build

This theme adds USWDS_CKEditor_Custom_Styles.scss into the CKeditor frame.

Export Database

A helper script has been provided to perform exports.

bin/db-export

You may specify a filename if you don't want to overwrite the default file location with a new export.

bin/db-export other-backup.sql

This process asks drush to export the database for us since it does some cleanup work before running the export.

Build and Deploy procedure

Production ready containers can be built and deployed from a local environment. To do so, proper secrets must be entered into the env.local file as environmental variables. This same procedure is used by CircleCI and is defined in .circleci/config.yml

# uses env.local
bin/cloudgov/container-build TAGNAME
bin/cloudgov/container-push TAGNAME
bin/cloudgov/login
bin/cloudgov/space dev
bin/cloudgov/deploy TAGNAME

Troubleshooting

If cms password is not accepted:

  • run bin/drush uli
  • copy the path of the url onto localhost in your browser's URL bar
  • follow the prompts to reset the password

Dockerfile-node runs the gulp start command.
