Links of the Docker-Compose - Laravel + Redis

Question

I am creating a development environment for a Docker-based 5.0 Standard project.

I managed a file docker-compose.yml for http://phpdocker.io and I made some modifications, he’s this way:

###############################################################################
#                          Generated on phpdocker.io                          #
###############################################################################
version: "3.1"
services:
  webserver:
    image: nginx:alpine
    container_name: rdias-app-webserver
    working_dir: /application
    volumes:
      - .:/application
      - ./phpdocker/nginx/nginx.conf:/etc/nginx/conf.d/default.conf
    ports:
      - "8080:80"
    links:
      - redis

  php-fpm:
    build: phpdocker/php-fpm
    container_name: rdias-app-php-fpm
    working_dir: /application
    volumes:
      - .:/application
      - ./phpdocker/php-fpm/php-ini-overrides.ini:/etc/php/7.0/fpm/conf.d/99-overrides.ini
    links:
      - redis

  redis:
    image: redis:alpine
    container_name: rdias-app-redis
    command: redis-server --requirepass Redis2019!
    ports:
      - "6379:6379"
    volumes:
      - ./redis:/data

The application is working properly but it does not connect in any way in redis.

Host machine can connect smoothly.

I don’t know if I link the right way. I’m not used to Docker.

Answer 1

I managed to solve the problem in a simple way. Just passing as the redis host, the string redis referring to the service name on the Docker.
