Instructions for building and using codeignter 4 in docker for development.

An extension can be part of the base php container but not enabled by default. An extension can also be built with pecl install or docker-php-ext-install. To enable an extension you can use a2enmod or docker-php-ext-enable with the later form being perfered.

docker build . -t nrb/php7.4-apache

The www-data user has been changed from 33 to 1000 to take advantage of this fact the container should have the following environment variables:

    environment:
      - APACHE_RUN_USER="#1000"
      - APACHE_RUN_GROUP="#1000"

The default data directory has been set to /var/www/public

To fully take advatage this setup:

• Makes sure Apache runs as user/group 1000
• Makes sure container runs as user/group 1000
• CodeIgntier is installed into /var/www with /var/www/public being exposed.

Since Code Igniter 4.2 Auto Routing (Legacy)Auto Routing (Legacy) has been disabled. There is only one route defined / routes to Home::index. There are three options:

• Enable Auto Routing (Legacy)
• Enable Auto Routing (Improved)
• Set Routing Rules

Standard Routing Rules expect a verb and URI as well as a target controller:

// Calls $Users->list()
$routes->get('users', 'Users::list');

Or can handle multiple verbs:

$routes->match(['get', 'put'], 'products', 'Product::feature');

# install CodeIgniter4
docker-compose run ci4 composer create-project codeigniter4/appstarter app

# chanege ./ to ./app/
sed -i "s/- .\/:\/var\/www/- .\/app:\/var\/www/g" docker-compose.yml

# set ci4 environment for testing
sed -z "s/# app.baseURL = ''/app.baseURL = 'https:\/\/example.com'/2" app/env > app/.env
sed -i "s/# CI_ENVIRONMENT = production/CI_ENVIRONMENT = development/g" app/.env
