Gitlab pipeline environment variables - how to transmission

GitLab CI/CD
1

Hi all,
My .gitlab-ci.yml deploy stage like :

deploy:
  stage: deploy
  before_script:
    - chmod 400 $SSH_KEY
  script:
    - ssh to deploy server "
        docker login ... && do something to pull source code including docker-compose.yml , .env
        docker-compose down &&
        docker-compose up -d"

There is a .env file :
DB_PASSWORD="***********"
I don’t want to store DB password in .env file, instead, I want to create a Gitlab ci/cd variables to store DB password and transmission it to container or host when deploy.
How can I do that ? Please give me some advice, thank you very much.

Hi @jack.chuong

I suppose the easiest is to generate the .env file and put it to deploy server

- echo "DB_PASSWORD=$DB_PASSWORD" > env && scp env deploy_server:/path/.env

or generate the file on the deploy server.

Another option is to use variables in docker-compose.yml

web:
  environment:
      - DB_PASSWORD=${DB_PASSWORD}"

and populate the environment variable on deploy server

- ssh to deploy server "
  ...
  DB_PASSWORD=${DB_PASSWORD} docker-compose up -d

Hi @balonik
Thank you for your suggestion, here what I did and it works:

deploy:
  stage: deploy
  before_script:
    - chmod 400 $SSH_KEY
  script:
    - ssh to deploy server "
        docker login ... && do something to pull source code including docker-compose.yml , .env &&
        echo "DB_PASSWORD=$DB_PASSWORD" >> .env && docker-compose down &&
        docker-compose up -d && echo "" > .env"

.env is a blank file , thank you very much.
