core update fails inside latest wordpress Docker image

[tofumatt]

Gutenberg's tests are failing because when we run wp-cli core update inside the official WordPress docker image (https://github.com/WordPress/gutenberg/blob/master/bin/install-wordpress.sh#L52) we get an error:

Warning: Unable to create directory wp-content/uploads/2018/08. Is its parent directory writable by the server?
Updating to version 4.9.8 (en_US)...
Downloading update from https://downloads.wordpress.org/release/wordpress-4.9.8-no-content.zip...
Unpacking the update...
Error: Could not create directory.

Removing the update command things work fine, regardless of WordPress image version.

I have no idea how WP CLI works but it seems an issue with it. 🤷‍♂️

@tofumatt The docker container seems to have permission problems, at least when creating directories (as the first warning already shows). Without the possibility to create a temporary folder, the update's zip file cannot be extracted.

You should ensure that the user that executes these commands within your Docker container has the needed permissions.

Yeah, I'm actually trying that out now, realising that WordPress/gutenberg@0b36845 might've been in our code to cover the permissions issue.

I'll close this issue because it seems that it is a problem with your environment. Just hit me up in the #cli channel in case you need further assistance.

Yup, you're totally right. Thanks and sorry for the noise! 👍
