depends_on:
- database
product:
image: node
container_name: product
restart: on-failure
build:
context: ./Product
dockerfile: Dockerfile
environment:
DATABASE_HOST: database
DATABASE_NAME: MyDB

看看env_file
:
从文件添加环境变量。可以是单个值或列表。
将其放入.env
:
DATABASE_HOST=database
DATABASE_NAME=MyDB
DATABASE_USER=myusername
DATABASE_PASSWORD=mypassword
SERVICE_PORT=80
然后在docker-compose.yml
customer:
image: node
build:
context: ./Customer
dockerfile: Dockerfile
env_file: .env
depends_on:
- database
product:
image: node
container_name: product
restart: on-failure
build:
context: ./Product
dockerfile: Dockerfile
env_file: .env
environment:
My_CUSTOM_CONFIG: secret
depends_on:
- consul
- database
