I have an obscure situation where I need to bind mount to a directory /foo/bar:baz inside a container.

Attempting something like this doesn't work because the : is interpreted as something other than part of the directory name:

services:
  foo:
    image: ...
    volumes:
      - "./source:/foo/bar:baz"

I feel like I must be missing something obvious in the documentation about how to escape the :, but can't find it.

There is a less used version of the syntax that allows services to be a map instead of single string: https://github/compose-spec/compose-spec/blob/main/05-services.md#volumes

services:
  foo:
    image: ...
    volumes:
      - type: bind
        source: ./source
        target: /foo/bar:baz
