I have a Node/Express app and I am using https://www.npmjs.com/package/dotenv-safe to include environment variables for dev and testing.
I am pushing my Docker repository to https://cloud.docker.com/app/gkatsanos/ and during AutoTesting (I have a docker-compose.test.yml), It seems that the environment variables are not found:

Locally the docker building and running works.
That's my dockerfile:
FROM node:8-alpine
EXPOSE 3000
ARG NODE_ENV
ENV NODE_ENV $NODE_ENV
RUN mkdir /app
WORKDIR /app
ADD package.json yarn.lock seed.js /app/
RUN yarn --pure-lockfile
ADD . /app
CMD ["yarn", "start"]
and my docker-compose.test.yml:
version: "3"
services:
sut:
build: .
command: yarn test
By the way, cloud.docker.com has a place in its UI that allows for environment variables to be added:
