WordPress VIP Go development for Docker

This repo provides a Docker-based environment for WordPress VIP Go development. It provides WordPress, MariaDB, Memcached, WP-CLI, and PHPUnit. It further adds VIP Go mu-plugins and a Photon server to closely mimic a VIP Go environment.

"Classic" VIP and non-VIP

For an environment suitable for "classic" VIP development, check out my docker-wordpress-vip repo.

If you only need a Docker WordPress development environment for a single plugin or theme, my docker-compose-wordpress repo is a simpler place to start.

Set up

Clone or fork this repo.
Add project.test to your /etc/hosts file:
```
127.0.0.1 localhost project.test
```
Edit update.sh to provide your VIP Go repo in the wp_repo variable.
Run ./setup.sh.
Run docker-compose up -d.

Install WordPress

docker-compose run --rm wp-cli install-wp

Log in to http://project.test/wp-admin/ with wordpress / wordpress.

Alternatively, you can navigate to http://project.test/ and manually perform the famous five-second install.

WP-CLI

You will probably want to create a shell alias for this:

docker-compose run --rm wp-cli wp [command]

Running tests (PHPUnit)

The testing environment is provided by a separate Docker Compose file (docker-compose.phpunit.yml) to ensure isolation. To use it, you must first start it, then manually run your test installation script. These are example commands and will vary based on your test scaffold.

Note that, in the PHPUnit container, your code is mapped to /app.

docker-compose -f docker-compose.yml -f docker-compose.phpunit.yml up -d
docker-compose -f docker-compose.phpunit.yml run --rm wordpress_phpunit /app/bin/install-wp-tests.sh

Now you are ready to run PHPUnit. Repeat this command as necessary:

docker-compose -f docker-compose.phpunit.yml run --rm wordpress_phpunit phpunit

Configuration

Put project-specific WordPress config in conf/wp-local-config.php and PHP ini changes in conf/php-local.ini, which are synced to the container. PHP ini changes are only reflected when the container restarts. You may also adjust the Nginx config of the reverse proxy container via conf/nginx-proxy.conf.

Photon

A Photon server is included and enabled by default to more closely mimic the WordPress VIP production environment. Requests to /wp-content/uploads will be proxied to the Photon container—simply append Photon-compatible query string parameters to the URL.

Memcached

A Memcached server and object-cache.php drop-in are available via the separate docker-compose.memcached.yml but are not enabled by default. To use it, either manually merge it into the main docker-compose.yml or reference it explicitly when interacting with the stack:

docker-compose -f docker-compose.yml -f docker-compose.memcached.yml up -d

HTTPS support

This repo provide HTTPS support out of the box. The setup script generates self-signed certificates for the domain specified in .env. To enforce the use of HTTPS, comment out (or remove) HTTPS_METHOD: "nohttps" from the services/proxy/environment section of docker-compose.yml.

You may wish to add the generated root certificate to your system’s trusted root certificates. This will allow you to browse your dev environment over HTTPS without accepting a browser security warning. On OS X:

sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain certs/ca-root/ca.crt

Multiple environments

Multiple instances of this dev environment are possible. Make an additional copy of this repo with a different folder name. Then, either juggle them by stopping one and starting another, or modify /etc/hosts and .env to use another domain, e.g., project2.test.

Troubleshooting

If your stack is not responding, the most likely cause is that a container has stopped or failed to start. Check to see if all of the containers are "Up":

docker-compose ps

If not, inspect the logs for that container, e.g.:

docker-compose logs wordpress

Running update.sh again can also help resolve problems.

If your self-signed certs have expired (ERR_CERT_DATE_INVALID), simply delete the certs/self-signed directory, run ./certs/create-certs.sh, and restart the stack.
