I want to install additional software dependencies into an image, but this software is not available via apt, nor is it easy to install. To solve this, I want to run additional Docker stanzas in the image used by Caliban.

One way to do so would be to use a different base image (i.e. DEV_CONTAINER_ROOT); in that image, I would start from gcr.io/blueshift-playground/blueshift and then add my own software. I put a sample such Dockerfile at https://gist.github.com/eschnett/5390892b6d8348ea3be5ca35d95f4990.

Alternatively, one could specify these stanzas in .calibanconfig.json.

I tried the --image_id option, but this doesn't work. It works for caliban shell, but for caliban run it skips packing up the current directory.

@eschnett , I'm going to do a release right now that adds a "base_image" key to the .calibanconfig.json. If you have

{"base_image": "ubuntu"}

Caliban will inject that as the base image. This should get you going! I'll get that release out in ~20 minutes.
