depends

Template version

Compose V1/V2

Set the dependencies of a service.

After setting the dependencies of a service, Container Service can control the start sequence of containers, starting the containers one by one.

Orchestration example:

Note: Separate dependencies by using commas (,).

web:
  image: wordpress:4.2
  ports:
    - 80
  links:
    - db:mysql
  labels:
    aliyun.depends: db,redis
db:
  image: mysql
  environment:
    - MYSQL_ROOT_PASSWORD=password
redis:
  image: redis

Compose V3

Set the dependencies of a service.

The system starts services in dependency order. By default, the system waits for 3 minutes for a service to start. If the service fails to start within 3 minutes, the system will ignore this service and move on to deploy another service. However, the whole deployment fails.

Orchestration example:

version: '3'
services:
  web:
    build: .
    depends_on:
      - db
      - redis
  redis:
    image: redis
  db:
    image: postgres
