Description
docker-compose env_file overwrites values from .env with host value if present in host's environment variables. Otherwise correctly applies the value from .env file
Steps to reproduce the issue:
- Create a variable that has a set value on the host system
- Create a .env file with the same key but different value
- include in a service in the docker-compose.yml the following
env_file:- .env
- Print container env variables after running docker-compose up --build -d
Describe the results you received:
The value for the env var is the same as the host
Describe the results you expected:
The value for the env var from the .env file
Additional information you deem important (e.g. issue happens only occasionally):
