bash - 如何简化 YAML CircleCI 配置以获得更好的可读性？

Question

我对持续集成还很陌生，到目前为止我非常喜欢它。我想知道是否有可能使配置文件更好地可读和简化。

我之所以问这个问题，是因为我在开发和生产模式中使用相同的工作流程。

如何保持配置“干燥”，而不需要一遍又一遍地复制粘贴相同的配置文件？

我可以用 BASH 脚本做一些事情吗？

我的配置:

version: 2
jobs:
  production:
    working_directory: ~/production-theme
    docker:
    - image: circleci/node:10.16
    steps:
    - add_ssh_keys:
        fingerprints:
        - xxx
    - store_test_results:
        path: test-results
    - checkout
    - restore_cache:
        name: Restore Yarn Package & Packge.json Cache
        keys:
        - yarn-packages-{{ checksum "yarn.lock" }}
        - v1-dependencies-{{ checksum "package.json" }}

您可以使用 CircleCI 配置的“commands”和“executors”键。

更多内容请看这里: https://circleci.com/docs/2.0/reusing-config/#the-commands-key https://circleci.com/docs/2.0/reusing-config/#executors

应用它，您的配置可能会变得更具可读性并且更短。

将 docker 定义包装在“executors”内:

executors:
  node:
    docker:
      - image: circleci/node:10.16

所有步骤定义都组合在commands: flow: ...下。与此同时，工作变得相当渺茫，因为它们将重用“flow”命令:

jobs:
  production:
    executor: node
    working_directory: ~/production-theme
    steps:
      - flow:
          environment: "production"
          yarn: "yarn prod-build"

更新.config.yml:

version: 2.1

executors:
  node:
    docker:
      - image: circleci/node:10.16

commands:
  flow:
    parameters:
      environment:
        type: string
        default: "production"
      yarn:
        type: string
        default: "yarn prod-build"
    steps:
      - add_ssh_keys:
          fingerprints:
            - xxx
      - store_test_results:
          path: test-results
      - checkout
      - restore_cache:
          name: Restore Yarn Package & Packge.json Cache
          keys:
            - yarn-packages-{{ checksum "yarn.lock" }}
            - v1-dependencies-{{ checksum "package.json" }}
            - yarn-packages-
            - v1-dependencies-
      - run:
          name: Install Yarn Packages
          command: yarn install
      - run:
          name: Building Repo
          command: << parameters.yarn >>
      - save_cache:
          name: Save Yarn Package Cache
          key: dependency-cache-{{ checksum "package.json" }}
          paths:
            - ./node_modules
      - run:
          name: Run SSH keyscan
          command: ssh-keyscan ${hostname} >> ~/.ssh/known_hosts
      - run:
          name: Install Rysnc
          command: sudo apt-get install rsync
      - run:
          name: Upload files to theme folder
          command: rsync -avP --delete-before --exclude 'node_modules' --exclude '.git'

            --exclude '.prettierrc' --exclude '.stylelintignore' --exclude '.stylelintrc'
            --exclude 'env.json' --exclude 'package.json' --exclude 'yarn.lock' --exclude
            'README.md' ~/<< parameters.environment >>-theme ${username}@${hostname}:/var/www/html/${site_name}/wp-content/themes/

          environment: "production"
          yarn: "yarn prod-build"


  development:
    executor: node
    working_directory: ~/develop-theme
    steps:
      - flow:
          environment: "develop"
          yarn: "yarn test-build"

请注意，我刚刚修改了您的配置，但尚未对其进行测试，因此可能存在轻微的拼写错误。
