[BUG] Docker Dev Containers pull from git Host ENV variables fail #142

Description

Description

When pulling from a github repo to create a dev container, using the docker app Host ENV variables pass through fails. With a compose-dev.yaml file in root does not pass the host environment variables.

Steps To Reproduce

On the host before docker dev pull enter into bash/terminal/cmd:

export MYSQL_DATABASE="database"
export MYSQL_ROOT_PASSWORD: "password"

docker create new dev environment and pull a github with "compose-dev.yaml" in the root,
compose-dev.yaml:

version: '3.8'

services:
  mysql:
    image: mysql:8.0
    volumes:
      - mysql-data:/var/lib/mysql
    environment:
      MYSQL_DATABASE: ${MYSQL_DATABASE_FAILS}
      MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD_FAILS}
      TEST_ENV:PASSES
    ports:
      - 3306:3306


volumes:
  mysql-data:

Inspect the container or run 'printenv' to view empty container ENV variables besides the hard coded TEST_ENV

% printenv
MYSQL_DATABASE: 
MYSQL_ROOT_PASSWORD: 
TEST_ENV:PASSES

Anything else?

I may have messed up steps to reproduce as it was from a private repo which I snipped down, but it should work related to the mysql server
