CakePHP Docker Stack

Two containers:

composer — PHP CLI + Composer (with the intl, zip, mbstring extensions CakePHP needs). Used on demand to scaffold/manage the app; it isn't a long-running service.
web — Apache + PHP (intl, pdo_mysql, mbstring, zip, gd, mod_rewrite) serving ./app/webroot.
db — MySQL 8.4, database cakephp, user cakephp / password cakephp (root password root). Data persists in the db_data named volume. Port 3306 is published to the host if you want to connect with a GUI client (Workbench, TablePlus, etc.).

composer and web share the ./app directory as the CakePHP application root. app/config/app_local.php is already pointed at the db service (host db, database/user/password cakephp).

First-time setup

The app was scaffolded with:

docker compose build
docker compose run --rm --entrypoint sh composer -c \
  "composer create-project --prefer-dist cakephp/app /tmp/app --no-interaction && cp -a /tmp/app/. /var/www/html/"

(Scaffolding via /tmp inside the container and copying out avoids a Composer bug deleting temp files directly on a Windows bind mount.)

Usage

Start the site:

docker compose up -d web

Visit http://localhost:8080

Run Composer commands against the app (e.g. installing a plugin):

docker compose run --rm composer require cakephp/authentication

Run bin/cake console commands via the web container:

docker compose exec web php bin/cake.php bake controller Articles

Database

Bring the DB up alongside the app:

docker compose up -d db web

Run migrations/bake against it once you have tables:

docker compose exec web php bin/cake.php migrations migrate

Connect from a host GUI client at 127.0.0.1:3306 using cakephp / cakephp (or root / root).

Geo (dereuromark/cakephp-geo)

The Geo plugin is installed and loaded (app/src/Application.php). Setup:

Geocoding (address <-> lat/lng) uses the Google Maps provider, configured in app/config/app.php under Geocoder.
Map tiles (LeafletHelper) are served by MapTiler, configured under Leaflet.tileLayer.

Both need API keys, passed into the web container as environment variables:

cp .env.example .env
# edit .env and set GOOGLE_MAPS_API_KEY and MAPTILER_API_KEY
docker compose up -d web

Google Maps API key (Geocoding API enabled): https://console.cloud.google.com/google/maps-apis/credentials
MapTiler API key: https://cloud.maptiler.com/account/keys/

Without keys, geocoding calls and map tiles will fail/return blank tiles, but the rest of the app is unaffected.
