 When running WP-CLI via the `cli` variants of this image, it is important to note that they're based on Alpine, and have a default `USER` of Alpine's `www-data`, whose UID is `82` (compared to the Debian-based WordPress variants whose default effective UID is `33`), so when running `wordpress:cli` against an existing Debian-based WordPress install, something like `--user 33:33` is likely going to be necessary (possibly also something like `-e HOME=/tmp` depending on the `wp` command invoked and whether it tries to use `~/.wp-cli`). See [docker-library/wordpress#256](https://github.com/docker-library/wordpress/issues/256) for more discussion around this.

+For example, to adjust common `php.ini` flags like `upload_max_filesize`, you could create a `custom.ini` with the desired parameters and place it in the `$PHP_INI_DIR/conf.d/` directory.
