packagecloud へのパッケージのパブリッシュ

packagecloud は、ホスティングされているパッケージ リポジトリ サービスです。 packagecloud を使用すると、事前構成なしで npm、Maven (Java)、Python、apt、yum、RubyGem の各リポジトリをホスティングすることができます。

Configure environment variables

$PACKAGECLOUD_TOKEN の設定

Under project settings in CircleCI, create an environment variable with the name PACKAGECLOUD_TOKEN, containing the value of a packagecloud API token. This environment variable will be used to authenticate with the packagecloud API directly, or using the packagecloud CLI.

The packagecloud CLI will automatically read this environment variable from the system when interacting with repositories.

Alternatively, if you prefer to keep your sensitive environment variables checked into git, but encrypted, you can follow the process outlined at circleci/encrypted-files.

packagecloud:enterprise 用の $PACKAGECLOUD_URL の設定

Only set the $PACKAGECLOUD_URL if you’re a packagecloud:enterprise customer

This setting is only for packagecloud:enterprise customers. Under project settings in CircleCI, set the $PACKAGECLOUD_URL environment variable to the URL of the packagecloud:enterprise installation.

packagecloud CLI のインストール

To use the packagecloud CLI from CircleCI, install it using RubyGems by adding the following run step to your .circleci/config.yml under the job that is configured to deploy the package:

- run:
   name: packagecloud CLI のインストール
   command: gem install package_cloud

The CLI will automatically use the $PACKAGECLOUD_TOKEN environment variable to authenticate against the packagecloud service.

Using dependency caching

If you want to cache this dependency between builds, you can add the package_cloud gem to a Gemfile and follow CircleCI’s guide for Caching Dependencies.

Pushing packages with the packagecloud CLI

The build processes for package types will vary, but pushing them into a packagecloud repository is quite simple. To add packages to a repository from your CircleCI builds, add a step in your deploy configuration that uses the packagecloud CLI.

The following is a full example .circleci/config.yml that will checkout a git repository, run a make task (this command can be anything configured to build your package), then deploy the package to a packagecloud repo.

version: 2
defaults: &defaults
  working_directory: ~/repo
  docker:
    - image: circleci/ruby:2.7
      auth:
        username: mydockerhub-user
        password: $DOCKERHUB_PASSWORD  # context / project UI env-var reference
jobs:
  build:
    <<: *defaults
    steps:
      - checkout
      - run:
          name: Build the package
          command: make
      - persist_to_workspace:
          root: ~/repo
          paths: .
  deploy:
    <<: *defaults
    steps:
      - attach_workspace:
          at: ~/repo
      - run:
          name: packagecloud CLI のインストール
          command: gem install package_cloud
      - run:
          name: deb パッケージのプッシュ
          command: package_cloud push example-user/example-repo/debian/jessie debs/packagecloud-test_1.1-2_amd64.deb
workflows:
  version: 2
  package-deploy:
    jobs:
      - build
      - deploy:
          requires:
            - build

Deploy npm packages

CircleCI users can deploy packages directly to npm registries hosted on packagecloud.

Configure the test job

This job will retrieve the project code, install its dependencies and run any tests in the NodeJS project:

jobs:
  test:
    <<: *defaults
    steps:
      - checkout

      - restore_cache:
          keys:
          - v1-dependencies-.
          # 正確な一致が見つからない場合は、最新のキャッシュの使用にフォールバックします
          - v1-dependencies-

      - run: npm install
      - run:
          name: テストの実行
          command: npm test

      - save_cache:
          paths:
            - node_modules
          key: v1-dependencies-

      - persist_to_workspace:
          root: ~/repo
          paths: .

Configure the deploy job

The next job configured is the deploy job. This job will authenticate and publish to the packagecloud npm registry:

jobs:
...
  deploy:
    <<: *defaults
    steps:
      - attach_workspace:
          at: ~/repo
      - run:
          name: レジストリ URL の設定
          command: npm set registry https://packagecloud.io/example-user/example-repo/npm/
      - run:
          name: レジストリでの認証
          command: echo "//packagecloud.io/example-user/example-repo/npm/:_authToken=$PACKAGECLOUD_TOKEN" > ~/repo/.npmrc
      - run:
          name: パッケージのパブリッシュ
          command: npm publish

• Set registry URL : This command sets the registry to URL that will be used by the npm CLI.
• Authenticate with the registry : This command will set the authToken to be used by the npm CLI to the environment variable configured in the project settings.
• Publish package : Publish the package to the configured npm registry on packagecloud.

The packagecloud npm registry URL is in the following format:

https://packagecloud.io/:username/:repo_name/npm/

The full .circleci/config.yml should look something like this:

version: 2
defaults: &defaults
  working_directory: ~/repo
  docker:
    - image: circleci/node:8.9.1
      auth:
        username: mydockerhub-user
        password: $DOCKERHUB_PASSWORD  # context / project UI env-var reference
jobs:
  test:
    <<: *defaults
    steps:
      - checkout

      - restore_cache:
          keys:
          - v1-dependencies-.
          # 正確な一致が見つからない場合は、最新のキャッシュの使用にフォールバックします
          - v1-dependencies-

      - run: npm install
      - run:
          name: テストの実行
          command: npm test

      - save_cache:
          paths:
            - node_modules
          key: v1-dependencies-

      - persist_to_workspace:
          root: ~/repo
          paths: .
  deploy:
    <<: *defaults
    steps:
      - attach_workspace:
          at: ~/repo
      - run:
          name: レジストリ URL の設定
          command: npm set registry https://packagecloud.io/example-user/example-repo/npm/
      - run:
          name: レジストリでの認証
          command: echo "//packagecloud.io/example-user/example-repo/npm/:_authToken=$PACKAGECLOUD_TOKEN" > ~/repo/.npmrc
      - run:
          name: パッケージのパブリッシュ
          command: npm publish
workflows:
  version: 2
  test-deploy:
    jobs:
      - test
      - deploy:
          requires:
            - test

The workflows section will tie together both the test and deploy jobs into sequential steps in the build process.
