AQUI ESTÁ A SOLUÇÃO DEFINITIVA | Gitlab CI e Docker: Pipeline de entrega contínua

Calma pessoal, o grande problema é que o MySql não encontra o arquivo mysql.sock.

Então faça assim: no mesmo diretório onde está o arquivo docker-compose.yml, crie uma pasta com o nome mysqld.

O seu arquivo docker-compose.yml fica assim:

version: '3'

services:
  db:
    image: mysql:5.7
    ports:
      - '3306:3306'
    environment:
      MYSQL_DATABASE: 'todo_dev'
      MYSQL_USER: 'devops_dev' 
      MYSQL_PASSWORD: 'mestre'
      MYSQL_ROOT_PASSWORD: 'senha'

    volumes:
      - ./mysqld:/var/run/mysqld
  web:
    image: aluracursos/django_todolist_image_build
    volumes:
      - ./env:/usr/src/app/to_do/.env
      - ./mysqld:/var/run/mysqld
    ports:
      - '8000:8000'
    depends_on:
      - db

Presta atenção nos volumes - incluiu a linha:

- ./mysqld:/var/run/mysqld

O arquivo env tem de ser renomeado para .env, e ele deverá ser assim:

[config]
# Secret configuration
SECRET_KEY = 'r*5ltfzw-61ksdm41fuul8+hxs$86yo9%k1%k=(!@=-wv4qtyv'

# conf
DEBUG=True

# Database
DB_NAME = "todo_dev"
DB_USER = "devops_dev"
DB_PASSWORD = "mestre"
DB_HOST = "mysql"
DB_PORT = "3306"

Pronto: Só rodar os comandos na sequência. Vai funcionar na hora!

Ao rodar o comando docker-compose run web python manage.py makemigrations ja apresenta o seguinte erro


The above exception was the direct cause of the following exception:
