Wordpress: wp-content/uploads is not writable in 4.9.8 image

[tofumatt]

We're encountering issues over at https://github.com/wordpress/gutenberg with the latest wordpress image (4.9.8). See: https://github.com/WordPress/gutenberg/issues/8418

We can't run wp-cli core update because wp-content/uploads is not writable. This line errors: https://github.com/WordPress/gutenberg/blob/master/bin/install-wordpress.sh#L52 with the bug in the above issue.

I don't know what caused this change because I'm finding it hard to track how/where this image is built from, but changing back to 4.9.7 image (changing the image we use from wordpress to wordpress:4.9.7 in our docker-compose.yml) "fixes" the issue.

Removing that update command things seem to also run okay, but we should be able to run it. I think eventually anything else that interacts with that folder will cause errors.

Was a permission changed or something?

It's possible this isn't your fault actually, I just have no idea what's up. It seems that WP CLI can't update without an error. Running wp-cli core update against the wordpress image runs into errors.

Turns out this is a permissions issue. Adding -u 33 to our wp-cli commands (using the wordpress:cli image) makes it work, but I wonder why that's needed at all.

I'll leave it to you if you want to leave this open, as I think requiring the -u 33 argument is quite weird, but it seems this isn't exactly the issue I thought it was...

I think this is actually a duplicate of https://github.com/docker-library/wordpress/issues/256. :+1:

I think this is actually a duplicate of #256. 👍

Sounds right. I get why resolving this one is tough and the solutions in #256 seem okay to me... Maybe to resolve this the docs could at least mention the solutions in #256? 🤷‍♂️

Good idea; added a little blurb over in https://github.com/docker-library/docs/pull/1284. :+1:
