Checking Extensions on Laravel Sail and Vapor

One of the Protect Earth API volunteers was looking into using Laravel Excel to add “Download CSV” functionality to Protect Earth’s amazing new Laravel Nova-powered backend to finally replace Airtable, and they said “It needs the GD extension, which I don’t think Sail or Vapor have enabled?” Let’s find out how to check.

Find Enabled Extensions on Laravel Sail

Sail, being mostly just Docker, lets you run arbitrary commands, like php -m which will list all the modules its got enabled. As we’re looking for a specific module let’s slice that list down a bit with grep.

$ sail php -m | grep gd

Nice, sail has gd installed and enabled by default.

Find Enabled Extensions on Laravel Vapor

The first thing I tried was doing exactly that through Vapor CLI, but I was getting some odd results.

$ vapor command --command="php -m"


   ERROR  Command "php" is not defined.

Welp, I hope it is, but perhaps the command command has changed and it only wants to talk to actual commands? Whatever, let’s try this another way.

$ vapor tinker --code="dd(phpinfo());" | grep GD

GD Support => enabled
GD Version => bundled (2.1.0 compatible)
GD imaging => Rasmus Lerdorf, Stig Bakken, Jim Winstead, Jouni Ahto, Ilia Alshanetsky, Pierre-Alain Joye, Marcus Boerger, Mark Randall

Wahey! There we go. Thanks.

Finally, my reforestation charity Protect Earth is free of Airtable, which served us well for the first few years but now we’re up to 40,000 trees with another 40,000+ coming this winter, it’s getting a bit unwieldy.
