ImageMagick errors on PHP 8.3 image after recent updates

[yobottehg]

Since some days I get the following ImageMagick errors on the official PHP 8.3 image:

[error] ImageMagick error 127: sh: 1: exec: identify: not found

I use Drupal 10.3 and the ImageMagick module. Has something changed what I need to adjust in the settings?

@yobottehg ImageMagick didn't exist on our 8.3 image until about a week ago; my guess would be that your app's integration with ImageMagick was failing silently previously, and now hat ImageMagick exists it's failing explicitly.

Right now ImageMagick isn't fully supported by the extension installer the images use, so that could be why it doesn't work seamlessly. @AaronFeledy has been working on this and may be able to put together a working example for you.

I successfully tested this with the 8.3 image by placing it in index.php and opening it in the browser.

If something is still not working, please provide more info.

@AaronFeledy and @reynoldsalec I was able to run the script sucessfully.

However to get the Drupal imagemagick module working again i needed to explicitly install imagemagick via apt-get in the build_as_root section.

I think this is unrelated to the docker extension but more to the base docker image which apparently did not have this installed anymore.

[AaronFeledy]

You're right. It seems Drupal's imagick module uses the convert binary instead of the PHP extension. That's a common enough use case that it should be in the image. Its removal is a regression so I'm reopening this issue. I'll work on fixing that later today.
