Output of docker-compose config
(Make sure to add the relevant -f and other flags)

ERROR: In file ./.env: environment variable name 'typesetting industry. Lorem Ipsum has been' may not contains whitespace.

Steps to reproduce the issue

1. Create .env file with the this content:

LOREM="Lorem Ipsum is simply dummy text of the printing and
typesetting industry. Lorem Ipsum has been
"

1. Use docker-compose config or docker-compose build commands

Observed result

This issue occurs in docker-compose 1.24.0

If we rollback to docker-compose 1.23.2 the issue is fixed:

sudo curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

docker-compose build

docker-compose build
nginx uses an image, skipping
Building php
....

Expected result

Stacktrace / full error message

` ERROR: In file ./.env: environment variable name 'typesetting industry. Lorem Ipsum has been' may not contains whitespace.

I downloaded docker-compose-1.23.2 trying to reproduce your issue with this minimal setup :

docker-compose.yml:

version: "3"
services:
    test:
            image: alpine
            command: 'echo hello $FOO !'

.env

FOO="bar
zot"

docker-compose up, both with 1.23 and 1.24 fail to run such a configuration.
Actually this feature was discussed on https://github.com/docker/compose/issues/3527 without any obvious fix on his way as env file support in docker engine do _not_ support multilines. Please note that using quotes around a value do not wrap a value as it does in plan shell, as bash isn't involved in parsing the .env file.

I was getting the same error and i did not use export in .env file. I have defined the variable like this and it worked for me
var:FOO

[Hassanzadeh-sd]

remove whitespace between environments
FOO = "bar
to
FOO="bar

I want to set the following contents into a .env file which i will use in my docker-compose

ENV=dev
MY_SERVICE_ACCOUNT='{
  "type": "service_account",
  "project_id": "my-gcp-project",
  "private_key_id": "d8f6d9c92749",
  "private_key": "-----BEGIN PRIVATE KEY-----\nMIIEvQIBADANBgkqhkiG9w0BAQEFAASCBKcwgWI8\naewdr8VbO2sRk1AgmYGCu9s=\n-----END PRIVATE KEY-----\n",
  "client_email": "[email protected]",
  "client_id": "740",
  "auth_uri": "https://acnt.google.com/o/o2auth/auth",
  "token_uri": "https://o2auth.googleapi.com/token",
  "auth_provider_x509_cert_url": "https://www.googleapi.com/o2auth/vX/cert",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/xyz%40my-gcp-project.iam.gserviceaccount.com"
}'
MY_PHRASE="boo yaa"

It contains a JSON key of a GCP IAM Service Account in it.

I want to save that key in an environment variable called $MY_SERVICE_ACCOUNT.

But i am getting a ...may not contain whitespace error.

How do i bypass this? The Service Account key will certainly have whitespaces and stuff.

^ Facing the same issue. I have an environment variable that _has_ to have spaces

I've got the same problem, the issue was in CI/CD config, it was SERVICE_NAME:'value' instead of SERVICE_NAME=value.

Hey, guys, welcome to the club. Hope soon we can use multiline variables
