PHP and Node Versions
Your app is a special snowflake. Here are a few things you may want to customize further!
We try to detect your local version of PHP and match it (with a minimum of PHP 7.4). If we can’t determine the version, we default to version 8.0.
For NodeJS, we default to version 14.
You can define the PHP and NodeJS versions you want by adding/adjusting build arguments in the
[build] [build.args] PHP_VERSION = "8.1" NODE_VERSION = "14"
Alternatively, you can set (or over-ride) the build arguments when deploying:
fly deploy --build-arg "PHP_VERSION=8.1" --build-arg "NODE_VERSION=14"
