Devcontainer with docker-compose

I'm pointing to my repo where my devcontainer points to a dockerComposeFIle: 
  "name": "Dev Environment",
  "dockerComposeFile": "../docker-compose.yml",
  "service": "dev-env",
  "name": "Dev Environment",
  "dockerComposeFile": "../docker-compose.yml",
  "service": "dev-env",
My docker-compose.yml points to the Dockerfile: 
services:
  dev-env: 
    build:
      context: .
      dockerfile: Dockerfile
      args:
        USERNAME: coder
services:
  dev-env: 
    build:
      context: .
      dockerfile: Dockerfile
      args:
        USERNAME: coder
But the workspace builder hangs here: 
#1: 📦 Cloned repository! [298.379884ms]
No Dockerfile specified, looking for a devcontainer.json...
Building in Devcontainer mode using /.devcontainer/devcontainer.json

Building in Devcontainer mode using /.devcontainer/devcontainer.json error: no Dockerfile or image found: no fallback image has been specified I would love to be able to get logs but I can't access anything beyond this. "Download Logs" is not available to click. I've even enabled "ENVBUILDER_LOG_LEVEL" = "debug" If I click stop it doesn't give me the ability to access logs. SSH fails

Oh well I just found the issues on GitHub about not supporting the compose. So I'm guessing this can be closed.

Its still a work in progress and requires your workspace image to be able to run docker images.
