如何在CircleCI 2.0的部署步骤中使用构建步骤中的docker映像？

Question

为从CircleCI 1.0迁移到2.0而苦苦挣扎的最后几天，虽然构建过程完成了，但部署仍然是一个大问题。 CircleCI文档并没有太大帮助。

这里是与我所拥有的相似的config.yml：

version 2

jobs:
  build:
    docker:
      - image: circleci/node:8.9.1

    steps:
      - checkout
      - setup_remote_docker

      - run
          name: Install required stuff
          command: [...]

      - run:
          name: Build
          command: docker build -t project .

  deploy:
    docker:
      - image: circleci/node:8.9.1
    steps:
      - checkout
      - run:
          name: Deploy
          command: |
            bash scripts/deploy/deploy.sh
            docker tag project [...]
            docker push [...]

workflows:
  version: 2
  build-deploy:
    jobs:
      - build
      - deploy:
          requires:
            - build
          filters:
            branches:
              only: develop

问题出在deploy作业中。我必须指定docker: -image点，但是我想重用build作业中已经安装了所有必需内容的环境。当然，我可以将它们安装在deploy作业中，但是具有多个deploy作业会导致代码重复，这是我不希望的。

Answer 1

如果标记由build阶段构建的图像，则可以在deploy阶段引用它：https://docs.docker.com/compose/compose-file/#labels

Answer 2

您可能希望保留到工作区并将其附加到您的部署作业中。之后，您将不需要使用“-结帐”
