> You can go the extra mile and turn the UID:GID into build args like the original parent and you're good to go. That doesn't help you if you're attempting to use pre-built/existing Docker images that are not built internally and make the assumption that “1000:1000 is good enough”. You then not only have to hack around Docker limitations, but also around someone else's broken assumption. |

Most pre-built images that I've come across don't require bind mounts to function.
Images like PostgreSQL aren't affected by this because you can use a named volume, and most pre-built applications that are shipped as images tend to store their state in a database and don't require bind mounts to function.
