Yii2 PHP Docker Image


Stable Build Status Development pipeline status

This is the repo of the official Yii 2.0 Framework image on DockerHub for PHP.

About

These Docker images are built on top of the official PHP Docker image, they contain additional PHP extensions required to run Yii 2.0 framework, but no code of the framework itself. The Dockerfile(s) of this repository are designed to build from different PHP-versions by using build arguments.

Available versions for yiisoftware/yii2-php

7.4-apache, 7.3-apache
7.4-fpm, 7.3-fpm

Deprecated or EOL versions

7.2-apache, 7.1-apache, 7.0-apache, 5.6-apache
7.2-fpm, 7.1-fpm, 7.0-fpm, 5.6-fpm

Setup

cp .env-dist .env

Adjust the versions in .env if you want to build a specific version.

Note: Please make sure to use a matching combination of DOCKERFILE_FLAVOUR and PHP_BASE_IMAGE_VERSION

Configuration

  • PHP_ENABLE_XDEBUG whether to load an enable Xdebug, defaults to 0 (false)
  • PHP_USER_ID (Debian only) user ID, when running commands as webserver (www-data), see also #15

Building

docker-compose build

Testing

docker-compose run --rm php php /tests/requirements.php

Xdebug

To enable Xdebug, set PHP_ENABLE_XDEBUG=1 in .env file

Xdebug is configured to call ip xdebug.remote_host on 9005 port (not use standard port to avoid conflicts), so you have to configure your IDE to receive connections from that ip.

If you are using macOS, you can fill xdebug.remote_host with host.docker.internal, due to a network limitation on mac (https://docs.docker.com/docker-for-mac/networking/#port-mapping)

### (macOS) configuration
xdebug.remote_host=host.docker.internal

FAQ

  • We do not officially support Alpine images, due to numerous issues with PHP requirements and because framework tests are not passing.
  • Depending on the (Debian) base-image (usually PHP <7.4) you might need to set X_LEGACY_GD_LIB=1
You can’t perform that action at this time.
