Docker UID isolation not enabled by default, configuration painful

7/10 High

Docker containers run as the logged-in user by default, creating security risks. Enabling UID namespaces requires a painful process that wipes all Docker state and recreates all images/containers. Additionally, only one UID namespace can be configured per Docker daemon, limiting inter-container isolation.

Query: “What are the most common pain points with Docker Desktop for developers in 2025?”4/7/2026

You can turn on UID namespaces, but the process is super painful and doing so wipes out the entire Docker state, requiring *all* images and containers to be recreated. It can also only have one UID namespace for all containers running under the same Docker daemon, which isn't what I'd consider sufficient isolation between containers.
