Non-alpine images?

[breandan]

Are there any plans to publish a non-Alpine based image? Alpine seems to have some issues with image scanning and mapping CVEs. And now that Ubuntu is minimal by default, there seems to be fewer reasons to use it. It would be nice to provide official support for DIND/DOOD on Ubuntu.

Not especially -- IMO, CVE mapping isn't a real solid justification for the added maintenance/churn. Is there a usability concern with Alpine? In my experience, using Docker-in-Docker is pretty self-contained, and it's a pretty rare use case where something non-Alpine is necessary (which makes sense, given that containers not relying on the specifics of the "host" / dockerd environment is kind of the entire point).

Closing given that this isn't something we're currently considering. If there's a solid justification to be made for the added maintenance burden of supporting addition variants, we'll reopen and reconsider. 👍

A dind image for Ubuntu would help the Docker-based, immutable dev environment movement.

I will probably be working on something like this, would be happy to do my work as a change to this repo.

I wrote a dind version inspired by this image using ubuntu as the base for my own use in jenkins-agent-dind. I'm using it for more than 1 year already and it's pretty solid, but probably overkill if not to be used for its sole purpose.

An official dind based on Ubuntu would greatly simplify the maintenance of my image, as a big part of its Dockerfile is due to the tricks to make it work.

As previously said, dind is useful as development environments, but especially useful for builders. And when we don't have a chance to use it as a sidecar, having to build our own is a challenge that could be avoided.

I'm willing to send a PR if you agree.
