hosh / docker-ubuntu-uid

Docker image with Ubuntu 18.04 bionic set up to mount a directory on the host computer and run commands as the (non root) host UID

The Dockerfile in this repository builds a ubuntu:16.04 container (with apt-get update and apt-get upgrade run) which lets you run commands inside the container using a UID and GID which are passed in environment variables from outside the container, so that any files created in a volume mount can be created as the user and group who initiated docker run.
