docker-compose does not set environment variables #7423
Description
Description of the issue
When using docker-compose up or docker-compose run -e ENVIRONMENT_VAR=value, environment variables are not being applied either through the -e command line parameters or from the docker-compose.yml file.
The docker-compose.yml file I am using is as follows:
version: '3'
services:
nginx-reverse-proxy:
image: nginx
volumes:
- C:/Users/<Username>/nginx-reverse-proxy/configdir:/etc/nginx/conf.d/
ports:
- "80:80"
environment:
NGINX_SERVER_NAME: "test.mysite.org"
NGINX_REMOTE_URL: "http://remote.mysiteengine.somehost.com:13345"Context information (for bug reports)
