images with sudo #84

Closed paleozogt closed 6 years ago

paleozogt commented 6 years ago

Could we get a -sudo variant?

The base Ubuntu images don't come with sudo. While this isn't really a problem when writing a Dockerfile, it can be a problem when using images on some CI/CD services that follow the best-practice of not running container processes as root.

This seems to vary by CI/CD service. Some (like GitLab) run the CI script as root in the container, while Azure Pipelines don't.

Even if we were to add sudo to these images, we would definitely not setup NOPASSWD: (or sudo group membership, for that matter), so there would still be enough setup for users of this image to do in order to be able to use sudo that I don't think it's worth us adding.

The steps required to install it are trivial (apt-get update && apt-get install -y sudo), and if one combines that with automated builds (https://docs.docker.com/docker-hub/builds/) and repository links (https://docs.docker.com/docker-hub/builds/#repository-links) and it's reasonably easy to have an up-to-date image built FROM this one with sudo pre-installed.
