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 7.3, 7.4, 8.0
• ICU 66.1 - 68.2

For older PHP or ICU versions check out the legacy branches:

• legacy-5.x
• legacy-7.x

Usage

Images are tagged with a PHP version and an ICU release separated with a dash. For example, the tag for PHP 8.0 and ICU 68.2 is 8.0-68.2.

bash
docker run -it --rm \
  -v `pwd`:/symfony -w /symfony \
  jakzal/php-intl:8.0-68.2 \
  ./phpunit /symfony/src/Symfony/Component/Intl/Tests/

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

bash
curl -Ls [***] | jq .[].name --raw-output

Image development

Generating docker files

The following command will re-generate all the Dockerfiles that then can be used to build PHP images with intl support:

bash
make generate

Building images

Build all images (will take a lot of time):

bash
make build-all

Build the latest PHP version with the latest ICU release:

bash
make build

Build the latest PHP version with a chosen ICU release:

bash
make build ICU_VERSION=68.2

Build a chosen PHP version with a chosen ICU release:

bash
make build ICU_VERSION=68.2 PHP_VERSION=8.0

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):

bash
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:8.0-68.2 bash

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

bash
git clone [***] \
  && cd symfony \
  && git checkout icu-68.2 \
  && composer install

Run all intl-data tests:

bash
./phpunit --group intl-data

Destroy the droplet when you're done:

bash
docker-machine rm symfony-intl
