在进行了所有的网络搜索并且没有任何答案之后,我想到了在这个平台上问这个问题。我有一个应用程序容器,我尝试与我的数据库容器连接,但是由于原因,我不知道我的应用程序无法连接。 我正在提供所需的所有相关信息。
这是我的docker-compose文件
version: '2'
services:
application: &application
image: gmasmatrix_application:latest
command: /start.sh
volumes:
- .:/app
depends_on:
- db
ports:
- 8000:8000
# cpu_shares: 874
# mem_limit: 1610612736
# mem_reservation: 1610612736
build:
context: ./
dockerfile: ./compose/local/application/Dockerfile
args:
- GMAS_ENV_TYPE=local
db:
image: mysql:5.7.10
environment:
MYSQL_DATABASE: gmas_mkt
MYSQL_ROOT_PASSWORD: pulkit1607
ports:
- '3306:3306'
volumes:
- my-db:/var/lib/mysql
volumes:
my-db:
我还更改了settings.py文件中的主机
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'gmas_mkt',
'USER': 'root',
'PASSWORD': 'pulkit1607',
'HOST': 'db',
'PORT': '3306',
}
}
这是我在运行docker-compose up文件时遇到的错误

无法弄清楚我在做什么错。
答案 0 :(得分:-1)
在settings.py文件中将“ HOST”:“ db”更改为“ HOST”:“ localhost ”。因为您将默认的MySQL端口从容器映射到主主机中的MySQL默认端口。
