We are happy to announce a new Dhall package to create Containerfile (or Dockerfile):
The dhall-docs output is also available here.

Do you have any experience reports to share? What kind of thing does this let you do, or make easier, compared with managing raw Dockerfile / Containerfile?
For a single Dockerfile it probably doesn’t make a ton of sense. I suspect the use case is more for generating lots of them out of variegated inputs.
We are using Dhall to manage a collection of containers which needs to share some common statements for CI purpose. Using direct Text interpolation is a bit error prone and that doesn’t compose well: e.g. should the common bits includes the CMD or ENV prefix? Also, having a common dhall-containerfile library let us re-use patterns such as a list of command separated by &&.
