docker - Circleci 2.0 基于 Dockerfile 构建

Question

我有一个 Node.JS 应用程序，我想使用 CircleCI 和 Amazon ECR 构建和测试它。该文档不清楚如何从存储库中的 Dockerfile 构建镜像。我看过这里:https://circleci.com/docs/2.0/building-docker-images/在这里 https://circleci.com/blog/multi-stage-docker-builds/但不清楚我在执行者下放置了什么。这是我到目前为止所得到的:

version: 2
jobs:
  build:
    docker:
    steps:
        - checkout
        - setup_remote_docker:
            version: 17.05.0-ce
        # build the image
        - run: docker build -t $ECR_REPO:0.1 .

CircleCI 失败并出现以下错误:

* The job has no executor type specified. The job should have one of the following keys specified: "machine", "docker", "macos"

基础镜像取自 Dockerfile。我正在使用 CircleCI 内置的 AWS 集成，因此我认为不需要添加 aws_auth。我需要在执行器下放置什么才能使其运行？

使用 Docker-in-Docker 配置构建它:

version: 2
jobs:
  build:
    working_directory: /app
    docker:
      - image: docker:17.05.0-ce-git
    steps:
      - checkout
      - setup_remote_docker
      - run:
          name: Install dependencies

              make

          paths:

      - run:

            mkdir -p /caches
            docker save -o /caches/app.tar app
      - save_cache:
          key: v1-{{ .Branch }}-{{ epoch }}
          paths:
            - /caches/app.tar
      - deploy:
