设置文件中的Docker-compose链接容器

Question

I have following docker-compse.yml:

version: '2'
services:
  api:
     build: api/.
     command: make run
     depends_on:
       - postgres
     links:
       - postgres:postgres
  processor:
     build: processor/.
     command: make run
     ports:
       - "9000:9000"
     links:
       - api:api

In my processor I have following setting.ini:

api=http://api:7000/

And Dockerfile for processor looks like following:

ADD ./src/processor/setting.ini /etc/app/processor/setting.ini

When running this via docker-compose up I got errors that processor couldn't see the api. Is it possible to link them?

Answer 1

Yes, just add the link to your processor service:

version: '2'
services:
  api:
    build: api/.
    command: make run
    depends_on:
      - postgres
    links:
      - postgres:postgres
  processor:
    build: processor/.
    links:
      - api:api
    command: make run
    ports:
      - "9000:9000"

I moved your links section directly into your definition of processor . This is where links should be defined (see Compose File Reference ).
