Thanks for these images!
Just a heads up that the cimg/php:7.3-node and cimg/php:7.2-node images appear to be missing the PHP DOM extension.
I see a “Class ‘DOMDocument’ not found” message when running composer test (which runs vendor/bin/phpunit).
The cimg/php:7.4-node image isn’t affected by the same issue — it appears to have the necessary DOM extension.
