WARNING: Python-dotenv could not parse statement starting at line X

[LQss11]

Let's say I have an env file like this:
docker.env

App__PathToFiles="C:\\Program Files\\SOMEPATH\\"
App__SomeOtherKey="Value"

and then passing it as an envfile in docker compose
docker-compose.yaml

version: '3.3'
services:
  app:
    image: alpine
    container_name: app
    tty: true
    env_file:
      - ./docker.env

Running docker-compose up with that config produces this error:

WARNING: Python-dotenv could not parse statement starting at line 1

This is because bashlash telling env to ignore the double quote which will break the structure of the config.

Hi @LQss11, I believe it is due to the unnecessary double quotes in the variable value.

I tested it with the same content and it didn't work either.

% cat > appsettings.json <<EOF
{
    "App": {
        "PathToFiles": "C:\\\\Program Files\\\\SOMEPATH\\\\",
        "SomeOtherKey": "Value"
    }
}
EOF
% dotnet-appsettings-env-darwin-arm64 -type docker | tee docker.env
App__PathToFiles="C:\\Program Files\\SOMEPATH\\"
App__SomeOtherKey="Value"
$ cat > docker-compose.yml <<EOF
version: '3.3'
services:
  app:
    image: alpine
    container_name: app
    tty: true
    env_file:
      - ./docker.env
EOF
% docker-compose up
unexpected character "\"" in variable name near "Value\"\n"

Removing the double quotes worked as expected.

% dotnet-appsettings-env-darwin-arm64 -type docker | tr -d \" | tee docker.env
App__PathToFiles=C:\\Program Files\\SOMEPATH\\
App__SomeOtherKey=Value
% docker-compose up -d

Can you remove the double quotes from your docker.env file and see if it will work?
