CircleCi：无法通过http + docker：// localhost连接到Docker守护程序

Question

在我的Node.js项目的测试，我开始docker-compose通过child_process.spawn。

运行CircleCi时，构建失败，并显示以下错误：

Couldn't connect to Docker daemon at http+docker://localhost - is it running?

这是.circleci/config.yml：

version: 2
jobs:
  build:
    docker:
      # specify the version you desire here
      - image: circleci/node:8

    working_directory: ~/repo

    steps:
      - checkout

      # Download and cache dependencies
      - restore_cache:
          keys:
          - v1-dependencies-{{ checksum "package.json" }}
          # fallback to using the latest cache if no exact match is found
          - v1-dependencies-

      - run: npm install

      - save_cache:
          paths:
            - node_modules
          key: v1-dependencies-{{ checksum "package.json" }}

      # run tests!
      - run: npm test

我相信，最近才遇到这个问题。我认为您的设置中唯一缺少的是setup_remote_docker在运行任何使用之前docker-compose。例如：

working_directory: ~/repo

steps:
  # ...

  - setup_remote_docker

  # run tests!
  - run: npm test

希望这可以帮助！
