Docker images for testing the Symfony Intl Component

Docker images for running tests of the Symfony Intl Component against various ICU/Intl versions. These images are not meant to be used on production systems.

Supported versions

• PHP 8.1 - 8.3
• ICU 73.2 - 74.1

For older PHP or ICU versions check out older Docker image tags.

Usage

Images are tagged with a PHP version and an ICU release separated with a dash. For example, the tag for PHP 8.3 and ICU 74.1 is 8.3-74.1.

docker run -it --rm \
  -v `pwd`:/symfony -w /symfony \
  jakzal/php-intl:8.3-74.1 \
  ./phpunit /symfony/src/Symfony/Component/Intl/Tests/

To list all available tags run the following command (requires jq to be installed):

curl -Ls 'https://registry.hub.docker.com/v2/repositories/jakzal/php-intl/tags?page_size=20' | jq '.results[].name' --raw-output | sort

Image development

Building images

Build the latest PHP version with the latest ICU release:

make build

Build the latest PHP version with a chosen ICU release:

make build ICU_VERSION=74.1

Build a chosen PHP version with a chosen ICU release:

make build ICU_VERSION=74.1 PHP_VERSION=8.3

Running Symfony Intl tests

It's best to run these tests on a system that natively supports Docker. If you're not a Linux desktop user, you can create a digitalocean droplet with little effort (or use other cloud provider):

docker-machine create --driver digitalocean --digitalocean-access-token $DIGITAL_OCEAN_ACCESS_TOKEN \
                                            --digitalocean-image "ubuntu-19-04-x64" \
                                            --digitalocean-size "4gb" \
                                            --digitalocean-region "lon1" \
                                            symfony-intl
eval "$(docker-machine env symfony-intl)"
docker run --rm -it  jakzal/php-intl:8.3-74.1 bash

Clone the Symfony repository and switch to the branch you want to test:

git clone https://github.com/jakzal/symfony.git \
  && cd symfony \
  && git checkout icu-74.1 \
  && composer install

Run all intl-data tests:

./phpunit --group intl-data

Destroy the droplet when you're done:

docker-machine rm symfony-intl
