This image should only be used to specifically run xdebug workloads.
Other php images do not include xdebug because it slows performance just by being added as a php extension.
You will need to set the XDEBUG_REMOTE_HOST environment variable to the IP or hostname of the machine you wish
to connect and run Xdebug with. This defaults to host.docker.internal which allows the host to connect
when running Docker for Mac.
This repo was previously included in a mono repo and the last published
tag with that repo was php-7.3-fpm_xdebug_1.1.0. The CircleCI build process continues to publish versions to the same image
on Dockerhub. The first tag published with this repo is 2.0.0.
