我想知道如何在GitHub操作中的作业之间共享服务容器。在当前的工作流程中，容器在build步骤后被销毁。

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

env:
  RAILS_ENV: test
  RACK_ENV: test

  POSTGRES_USERNAME: postgres
  POSTGRES_HOST: localhost

  build:

      - name: Initialize Ruby
        uses: ruby/setup-ruby@v1
        with:
          bundler-cache: true
      - name: Setup Rails
        run: bin/setup
    services:
      postgres:
        image: postgres:15.1-alpine
        ports:
          - 5432:5432
        env:
          POSTGRES_PASSWORD: ${{ env.POSTGRES_PASSWORD }}
          POSTGRES_USER: ${{ env.POSTGRES_USERNAME }}
        # needed because the postgres container does not provide a healthcheck
        options: >-
          --health-cmd pg_isready 
          --health-interval 10s 
          --health-timeout 5s 
          --health-retries 5

  test:
    runs-on: ubuntu-latest
    needs: [ build ]
    steps:
      - name: Lint Ruby
