Backend server in gitlab-ci docker cypress e2e

Question

I am new to gitlab ci. I want to run integrated tests of my app using cypress. E2E tests require frontend (ionic, cypress) and backend (django, postgis). Running in my local machine everything works fine. First launch the backend server, and then run tests. Now I wanted to use gitLab CI but I don't know how to launch the backend server (i've been googling around but found nothing to my case), before launching the tests in the docker container (I'm also new to docker). I'm using a gitlab-ci.yaml I got from the cypress-gitlab network

stages:
  - build
  - test

# to cache both npm modules and Cypress binary we use environment variables
# to point at the folders we can list as paths in "cache" job settings
variables:
  npm_config_cache: "$CI_PROJECT_DIR/.npm"
  CYPRESS_CACHE_FOLDER: "$CI_PROJECT_DIR/cache/Cypress"

# cache using branch name
# https://gitlab.com/help/ci/caching/index.md
cache:
  key: ${CI_COMMIT_REF_SLUG}
  paths:
    - .npm
    - cache/Cypress
    - node_modules

# this job installs NPM dependencies and Cypress
install:
  image: cypress/base:10
  stage: build

  script:
    - npm ci
    # show where the Cypress test runner binaries are cached
    - $(npm bin)/cypress cache path
    # show all installed versions of Cypress binary
    - $(npm bin)/cypress cache list
    - $(npm bin)/cypress verify

# two jobs that run after "install" job finishes
# NPM dependencies and Cypress binary should be already installed
cypress-e2e:
  image: cypress/base:10
  stage: test
  script:
    - $(npm bin)/cypress run
  artifacts:
    expire_in: 1 week
    when: always
    paths:
    - cypress/screenshots
    - cypress/videos
    reports:
      junit:
        - results/TEST-*.xml

cypress-e2e-chrome:
  image: cypress/browsers:chrome67
  stage: test
  script:
    - $(npm bin)/cypress run --browser chrome
  artifacts:
    expire_in: 1 week
    when: always
    paths:
    - cypress/screenshots
    - cypress/videos
    reports:
      junit:
        - results/TEST-*.xml

The install job runs fine. The error occur on the job cypress-e2e. The error seems auto-explanatory and logic to me - no server running. My problem is I don't know how to introduce in the script the launch of the service. The output of the pipeline:
