I know it's possible to supply a GitHub HTTP URL as a service's build context:
version: '3.9'
services:
my-app:
build: https://github.com/rambo/my-app.git
The above works well for public repos. But what if the Dockerfile is stored in a private repo that requires authentication (e.g. via SSH). Is something like the below example supported?
services:
my-app:
build: ssh://git@github.com:rambo/my-app.git
I've tried multiple variations of the above configuration but nothing seems to work.
