wordmove: Wordmove commands (inc. wordmove init) throwing errors in Docker Wordpress container

UPDATE realised I was pulling from production, rather than remote in this comment. However, there is still an issue… see further down and the wordmove init error in this comment.

Had wordmove working brilliantly on a vagrant box (modified vccw box), but am attempting to move across to Docker to simlify config. I’m attempting to extend the Docker Wordpress image (with up to date Ruby etc.), and hitting an issue that, after much Googling, I’m getting nowhere with. I’m running as root (will this cause issues with wp-cli??), and getting the following issues when I try to run any wordmove command, even wordmove init.

Any help would be massively appreciated. It’s an awesome tool, and even more awesome when you know how good it is but cant have it!!!

Error: YIKES! It looks like you're running this as root. You probably meant to run this as the user that your WordPress install exists under.

If you REALLY mean to run this as root, we won't stop you, but just bear in mind that any code on this site will then have full control of your server, making it quite DANGEROUS.

If you'd like to continue as root, please run this again, adding this flag:  --allow-root

If you'd like to run it as the user that this site is under, you can run the following to become the respective user:

    sudo -u USER -i -- wp <command>
