How could i access to another container?

[stellarweb-studio]

I tried to build some testing process for my app, using Bitbucket pipelines.

The core testing tool is Cypress. I want to set up several docker containers and execute Cypress to test my app.

So, my bitbucket-pipelines.yml looks like this:

image: docker:stable

options:  docker: truepipelines:
  default:
    - step:        
        name: Install PHP app
        caches:
          - composer
        script:
          - cp config/db.sample.php config/db.php
          - sed -i "s/[HOSTNAME]/db/" config/db.php
          - sed -i "s/[DB_NAME]/dbname/" config/db.php
          - sed -i "s/[DB_USER]/usr/" config/db.php
          - sed -i "s/[DB_USER_PASSWORD]/pass/" config/db.php
          - cp web/index.sample.php web/index.php
          - docker run --name db --restart always -e MYSQL_DATABASE=dbname -e MYSQL_USER=usr -e MYSQL_PASSWORD=pass -e MYSQL_ALLOW_EMPTY_PASSWORD=yes -d -p 3306:3306 mariadb
          - docker run --name web -v="$BITBUCKET_CLONE_DIR:/app" -d -p 8000:80 yiisoftware/yii2-php:5.6-apache
          - docker run --name e2e -v="$BITBUCKET_CLONE_DIR:/app" --workdir /app --tty -d cypress/base:10
          - docker exec -i web composer install
          - docker exec -i db mysql -uroot dbname < ./migrations/data/structure.sql
          - docker exec -i e2e yarn install
          - docker exec -i e2e yarn run cypress run --config baseUrl=http://web --project ./        services:
          - docker
          - web
definitions:  
  services:    
    db:      
      image: mariadb
    web:      
      image: yiisoftware/yii2-php:5.6-apache
    e2e:     
      image: cypress/base:10

Overall, it works almost good, but for some reason I can't get access to web service inside e2e container. I tried to use container name, like http://web, but it doesn't work.

What is wrong here?

Hi @stellarweb-studio

I'm not sure if I can help you with this one, but I'm curious about something.
How is Cypress resolving the address http://web?
