| | Multi-stage build | Recommended | Recommended. Use images with a `dev` or `sdk` tags for build stages and non-dev images for runtime. | | ||
| | Ports | Can bind to privileged ports (under 1024) when running as root | Run as a non-root user by default. Applications can't bind to privileged ports (under 1024) when running in Kubernetes or in Docker Engine versions older than 20.10. Configure your application to listen on port 1025 and up inside the container. | | ||
| | Entry point | Varies by image | May have different entry points than Ubuntu-based images. Inspect entry points and update your Dockerfile if necessary. | | ||
| | Shell | Varies by image. Some include a shell, others don't | Runtime images don't contain a shell. Use `dev` images in build stages to run shell commands and then copy artifacts to the runtime stage. | |

There was a problem hiding this comment.
- The alpine/debian page has "No shell" as the row header. I prefer this - "Shell".
- We could mention that the default shell is bash for the dev variants, but it's the same for DOI so maybe no point.

Description
Added general Ubuntu to Debian DHI migration.
The tabbed comparison in the language examples is getting a bit wonky, although still correct. A lot of tabs, and it randomly picks alpine/debian as the final dhi image, whereas wolfi is probably going to alpine and ubuntu is probably going to debian. Will look at this in a followup.
