I’ve been meaning to look into Docker for a long while now. But, as always, time is the issue. In the last couple of days though I’ve been integrating BitBucket Pipelines into our workflow. BitBucket Pipelines is a continuous integration solution, which runs your project tests in a Docker container. So, naturally, I had to get a better idea of how the whole thing works.
“Docker for PHP Developers” article was super useful. Even though it wasn’t immediately applicable to BitBucket Pipelines, as they don’t currently support multiple containers – everything has to run within a single container.
The default BitBucket Pipelines configuration suggests the phpunit/phpunit image. If you want to run PHPUnit tests only, that works fine. But if you want to have a full blown Nginx and MySQL setup for extra bits (UI tests, integration tests, etc), then you might find smartapps/bitbucket-pipelines-php-mysql image much more useful. Here’s the full bitbucket-pipelines.yml file that I’ve ended up with.
