Recreating project_test-environment_1 ... done
Attaching to project_test-environment_1
test-environment_1 | variable1 = ; variable2 =
project_test-environment_1 exited with code 0
It seems like environment variables were not initialized. Using alternative syntax
environment:
- VAR1='variable 1'
- VAR2=222
given the same result too.

variable-substitution
docker inspect command to check if env variables are configured properly for that container.
I used version 3 as my docker-compose do not support the version you are using.
The .env file feature only works when you use the docker-compose up command and does not work with docker stack deploy.
You can use a $$ (double-dollar sign) when your configuration needs a literal dollar sign. This also prevents Compose from interpolating a value, so a $$ allows you to refer to environment variables that you don’t want processed by Compose.
If you forget and use a single dollar sign ($), Compose interprets the value as an environment variable and warns you:
WARNING: The VAR1 variable is not set. Defaulting to a blank string.
WARNING: The VAR2 variable is not set. Defaulting to a blank string.
the environment
option specifies which vars will be passed to the container. they are not available outside in the docker-compose file.
if you need env vars for your docker-compose file, create on the same directory a .env
file:
#.env
VAR1=variable1
VAR2=222
and now it should work for docker-compose up
remove the environment
option from the docker-compose - unless you need the vars inside the container, it makes no sense.
