docker-compose.yml 在单个 Google Compute Engine VM 上指定的多个服务

Question

I have a docker-compose.yml file which specifies two services AAA and BBB as follows,

version: "3.4"

services:
  AAA:
    platform: linux/amd64
    build: .
    image: AAA
    environment:
      - ENV_VAR=1
    volumes:
      - ./data:/root/data
    ports:
      - 5900:5900
    restart: on-failure
  
  BBB:
    image: BBB
    build: ./service_directory
    platform: linux/amd64
    environment:
      - PYTHONUNBUFFERED=1
    volumes:
      - ./data:/root/data
    ports:
      - 5901:5901
    restart: on-failure
    depends_on:
      - AAA

And here's my directory structure:

project
|  docker-compose.yml
|  Dockerfile
|
|--service_directory
   |
   |--Dockerfile

I'm led to believe that google cloud lacks direct docker-compose support, and one must translate the docker compose script into a cloudbuild.yaml file.

How should one specify the multiple services, the environment , ports , volumes information and the dependency of BBB on AAA in a cloudbuild.yaml file such that both services build on a single compute engine VM instance, as one would otherwise expect from running the docker compose up command?

Answer 1

Google Compute Engine VMs (running Linux) are functionally equivalent to any other Linux machine and you can run Docker Compose as you would elsewhere.

You may need to install Docker and Docker Compose as you would on any Linux host.

Google Cloud Build provides different functionality to Docker Compose; the two are not equivalent. Cloud Build is a cloud-based pipeline tool that is mostly used (but is not limited) to define the steps needed to create container images.
