Tagging @darylldoyle here as this pertains to internal tooling. I made this PR because I was wpsnapshots was failing when there was a union type in my codebase (php 8). I think wpsnapshots is using a docker image with PHP 7.4

@claytoncollie it seems that wp-local-docker doesn't use these images, it uses the ones over at https://github.com/10up/wp-php-fpm-dev. I'm actually unsure what purpose these images or even this repo serve.

The https://github.com/10up/wp-php-fpm-dev repo already has images for everything up to 8.2; they're just not included in wp-local-docker. There's a PR to add support for them here, it's also possible to manually upgrade by updating the image in your docker-compose.yml file within a project. E.G.

  # ...
  phpfpm:
    image: '10up/wp-php-fpm-dev:8.2-ubuntu'
  # ...

@darylldoyle My problem is not with wp local docker but with wpsnapshot. I have my project's container running PHP8 and am using union types on a function like this function my_function_with_two_return_types() : array| bool {}. The project works fine but when I run wpsnapshot create on this project, the command throws an error. I think it is because wpsnapshot is spinning up its own container to run the job.

Thanks @claytoncollie, I see what you mean! I feel like https://github.com/10up/wpsnapshots/blob/cf28870fcf0fa3cc3f3ad07c6bce74c713bf587b/docker/Dockerfile#LL1C6-L1C17 should be updated to use 10up/wp-php-fpm-dev rather than 10up/wp-php-fpm, since those are the new docker images 🤔

@dustinrue or @tylercherpak do you have any thoughts around this?

[darylldoyle]

Thanks @claytoncollie. It seems that the wpsnapshots docker image is no longer sourced from this repo, see #20 for details.

It's now built via a Github action from the https://github.com/10up/wpsnapshots repo. It looks like this file will need updating to use a more modern image. Likely one of the images in https://hub.docker.com/r/10up/wp-php-fpm-dev/ will be the best, since that has 8.* images. I need to dig in and see if that needs any modifications to the setup to work since those images are different.
