How to pass env to container building with Github Actions? - docker

Question

I'm create an CI/CD process with using docker, heroku and Github Action but I've got an issue with envs.
Right now when I'm running heroku logs I see that MongoServerError: bad auth : Authentication failed. and I think that this problem is in passing envs to my container and then using in github actions cause in code I pass simply process.env.MONGODB_PASS.
In docker-compose.yml I'm using envs from .env file, but Github Actions can't use this file because I put this file into .gitignore...
Here is my config:
.github/workflows/main.yml
name: Deploy
on:
push:
branches:
- develop
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v2
- uses: akhileshns/heroku-deploy#v3.12.12
with:
heroku_api_key: ${{secrets.HEROKU_API_KEY}}
heroku_app_name: "---"
heroku_email: "---"
usedocker: true
docker-compose.yml
version: '3.7'
networks:
proxy:
external: true
services:
redis:
image: redis:6.2-alpine
ports:
- 6379:6379
command: ["redis-server", "--requirepass", "---"]
networks:
- proxy
worker:
container_name: ---
build:
context: .
dockerfile: Dockerfile
depends_on:
- redis
ports:
- 8080:8080

- '8080'
env_file:
- .env
volumes:
- .:/usr/src/app
- /usr/src/app/node_modules
command: npm run dev

can someone tell me how to resolve this issue? thanks for any help!
