Orb のオーサリング プロセス


This orb authoring guide assumes you have read the Introduction to authoring an orb document and claimed your namespace. At this point you are ready to develop an orb.

Whether you are writing your first orb or getting ready for production level, we recommend using our orb development kit to get started. Alternatively, as orbs are packages of reusable configuration, they can be written manually, as singular yaml files, and published using our circleci orb cli.

Orb 開発キット

The orb development kit refers to a suite of tools that work together to simplify the orb development process, with automatic testing and deployment on CircleCI. The orb development kit is made up of the following components:


To begin creating your new orb with the orb development kit, follow these steps. The starting point is creating a new repository on GitHub.com.

Ensure the organization on GitHub is the owner for the namespace for which you are developing your orb. If this is your own personal organization and namespace, you need not worry.

  1. Create a new GitHub repository.
    The name of your repository is not critical, but we recommend something similar to “myProject-orb”. Orb レジストリ

    必要な項目の設定が終わると、新しいリポジトリの内容を確認するページが開き、生成された Git の URL が表示されます。 この URL をメモしておいてください。手順 2 で必要になります。 URL は SSH か HTTPS を選択できます。どちらを選択しても認証を行えます。 Orb レジストリ

  2. ターミナルを開き、orb init CLI コマンドを使用して新しい Orb プロジェクトを初期化します。

To initialize a public orb:

circleci orb init /path/to/myProject-orb

To initialize a private orb:

circleci orb init /path/to/myProject-orb --private

The circleci orb init command is called, followed by a path that will be created and initialized for our orb project. It is best practice to use the same name for this directory and the git project repo.

  1. Orb の完全自動セットアップ オプションを選択します。
    ? Would you like to perform an automated setup of this orb?:
      ▸ Yes, walk me through the process.
     No, I'll handle everything myself.

    When choosing the fully automated option, the Orb-Project-Template will be downloaded and automatically modified with your customized settings. The project will be followed on CircleCI with an automated CI/CD pipeline included.

    For more information on the included CI/CD pipeline, see the Orb Publishing Process documentation. Alternatively, if you would simply like a convenient way of downloading the Orb-Project-Template you can opt to handle everything yourself.

  2. Answer questions to configure and set up your orb.
    In the background, the orb init command will be copying and customizing the Orb Project Template based on your inputs. 各ディレクトリにある詳細な README.md ファイルには、それぞれのディレクトリのコンテンツに関する有益な情報が記載されています。 You will also be asked for the remote git repository URL that you obtained back in step 1.

    The Orb Project Template contains a full CI/CD pipeline (described in Orb Publishing Process) which automatically packs, tests, and publishes your orb.

    In the setup process you will be asked if you would like to save your Personal API Token into an orb-publishing context. Orb の開発版と安定版をパブリッシュするために、このトークンを格納しておくことが必要になります。

    Restrict a context by navigating to Organization Settings > Contexts.

    After completing your orb, you should see a new context called orb-publishing. この orb-publishing をクリックして、_セキュリティ グループ_を追加します。 セキュリティ グループを使うと、ジョブのトリガーを許可されたユーザーだけにアクセスを制限することができます。 プライベートのパーソナル API トークンにアクセスできるのも、これらのユーザーだけです。

    For more information, see the Contexts guide.

  3. Push the changes up to Github.
    During the setup process, the orb init command takes steps to prepare your automated orb development pipeline. CLI が処理を続行し、circleci.com でプロジェクトを自動的にフォローするには、その前に、CLI によって生成された修正済みのテンプレート コードがリポジトリにプッシュされている必要があります。 これを実行するよう要求されたら、別のターミナルから以下のコマンドを、「default-branch」を実際のデフォルト ブランチの名前に置き換えて実行します。
    git push origin <default-branch>

    Once complete, return to your terminal and confirm the changes have been pushed.

  4. Complete and write your orb.
    The CLI will finish by automatically following your new orb project on CircleCI and generating the first development version <namespace>/<orb>@dev:alpha for testing (a hello-world sample).

    You will be provided with a link to the project building on CircleCI where you can view the validation, packing, testing, and publication process. You should also see the CLI has automatically migrated you into a new development branch, named alpha.

    From your new branch you are now ready to make and push changes. From this point on, on every commit, your orb will be packed, validated, tested (optional), and can be published.

    When you are ready to deploy the first major version of your orb, find information on deploying changes with semver versioning in the Orb Publishing Process guide.

Orb の記述

Before you begin working on your orb, ensure you are on a non-default branch. We typically recommend starting your orb on the alpha branch.

$ git branch

* alpha

If you have run the circleci orb init command, you will automatically be in the alpha branch and have a repository with .circleci and src directories.

Example: Orb Project Structure

種類 名前

Orb のソース

Navigate to the src directory to look at the included sections.

Example: Orb Project “src” Directory

type name

The directories listed above represent orb components that can be included with your orb. @orb.yml acts as the root of your orb. You may additionally see scripts and tests directories in your project for optional orb development enhancements, which we will cover in the Scripts section and the Orb Testing Methodologies guide.

Each directory within src corresponds with a reusable configuration component type, which can be added or removed from the orb. If, for example, your orb does not require any executors or jobs, these directories can be deleted.


@orb.yml acts as the “root” to your orb project and contains the config version, the orb description, the display key, and imports any additional orbs if needed.

Use the display key to add clickable links to the orb registry for both your home_url (the home of the product or service), and source_url (the git repository URL).

version: 2.1

description: >
  サンプルの Orb の説明

  home_url: "https://www.website.com/docs"
  source_url: "https://www.github.com/EXAMPLE_ORG/EXAMPLE_PROJECT"

Author and add Reusable Commands to the src/commands directory. Each YAML file within this directory will be treated as an orb command, with a name which matches its filename.

Below is the greet.yml command example from the Orb Project Template.

description: >
  # ここには、このコマンドの目的を記述します。
  # 短くわかりやすい説明を心がけます。
    type: string
    default: "Hello"
    description: "適切なあいさつの選択"
  - run:
      name: あいさつを選択して Hello World を実行
      command: echo << parameters.greeting >> world

Author and add Usage Examples to the src/examples directory. Usage Examples are not for use directly by end users in their project configs, but they provide a way for you, the orb developer, to share use-case specific examples on the Orb Registry for users to reference.

Each YAML file within this directory will be treated as an orb usage example, with a name which matches its filename.

View a full example from the Orb Project Template.


Author and add Parameterized Executors to the src/executors directory.

Each YAML file within this directory will be treated as an orb executor, with a name that matches its filename.

View a full example from the Orb Project Template.


Author and add Parameterized Jobs to the src/jobs directory.

Each YAML file within this directory will be treated as an orb job, with a name that matches its filename.

Jobs can include orb commands and other steps to fully automate tasks with minimal user configuration.

View the hello.yml job example from the Orb Project Template.

description: >
  # ここには、このジョブの目的を記述します。
  # 短くわかりやすい説明を心がけます。

  - image: cimg/base:stable
    type: string
    default: "Hello"
    description: "適切なあいさつの選択"
  - greet:
      greeting: "<< parameters.greeting >>"


One of the major benefits of the orb development kit is a script inclusion feature. When using the circleci orb pack command (automated when using the orb development kit), you can use the value <<include(file)>> within your orb config code, for any key, to include the file contents directly in the orb.

This is especially useful when writing complex orb commands, which might contain a lot of bash code, (although you could use python too!).

    type: string
    default: "World"
    description: "あいさつする相手"
  - run:
        PARAM_TO: <<parameters.to>>
      name: greet ファイルで指定した相手にあいさつ
      command: <<include(scripts/greet.sh)>>
    type: string
    default: "World"
    description: "あいさつする相手"
  - run:
      name: 指定した相手にあいさつ
      command: echo "Hello <<parameters.to>>"

CircleCI configuration is written in YAML. Logical code such as bash can be encapsulated and executed on CircleCI through YAML, but, for developers, it is not convenient to write and test programmatic code within a non-executable format. Also, parameters can become cumbersome in more complex scripts as the <<parameter>> syntax is a CircleCI native YAML enhancement, and not something that can be interpreted and executed locally.

Using the orb development kit and the <<include(file)>> syntax, you can import existing scripts into your orb, locally execute and test your orb scripts, and even utilize true testing frameworks for your code.


To keep your scripts portable and locally executable, it is best practice to expect a set of environment variables within your scripts and set them at the config level. The greet.sh file, which was included with the special <<include(file)>> syntax above in our greet.yml command file, looks like this:

echo Hello "${PARAM_TO}"

This way, you can both mock and test your scripts locally.

Orb のテスト

Much like any other software, there are multiple ways to test your code and it is entirely up to you as the developer to implement as many tests as desired. Within your config file right now there will be a job named integration-test-1 that will need to be updated to test your orb components. This is a type of integration testing. Unit testing with orbs is possible as well.

Read our full Orb Testing Methodologies documentation.


Deciphering the difference between two versions of an orb can prove tricky. Along with semantic versioning, we recommend leveraging a changelog to more clearly describe changes between versions. The orb template comes with the CHANGELOG.md file, which should be updated with each new version of your orb. The file uses the Keep a Changelog format.

Orb のパブリッシュ

With the orb development kit, a fully automated CI and CD pipeline is automatically configured within .circleci/config.yml. This configuration makes it simple to automatically deploy semantically versioned releases of your orbs.

For more information, see the Orb Publishing Process guide.

Orb のカテゴリ設定

You can categorize your orb for better discoverability in the Orb Registry. Categorized orbs are searchable by category in the Orb Registry. CircleCI may, from time to time, create or edit orb categorizations to improve orb discoverability.


You can select up to two categories for your orb. These are the available categories:

  • Artifacts/Registry (アーティファクト/レジストリ)
  • Build (ビルド)
  • Cloud Platform (クラウド プラットフォーム)
  • Code Analysis (コード解析)
  • Collaboration (コラボレーション)
  • Containers (コンテナ)
  • Deployment (デプロイメント)
  • Infra Automation (インフラ自動化)
  • Kubernetes
  • Language/Framework (言語/フレームワーク)
  • Monitoring (モニタリング)
  • Notifications (通知)
  • Reporting (レポート)
  • Security (セキュリティ)
  • Testing (テスト)

The list of categories can also be obtained by running the circleci orb list-categories CLI command. You can view the detailed docs for this command here.

カテゴリへの Orb の追加

Add your orb to your chosen category by running circleci orb add-to-category <namespace>/<orb> "<category-name>". You can view the detailed docs for this command here.

カテゴリからの Orb の削除

Remove an orb from a category by running circleci orb remove-from-category <namespace>/<orb> "<category-name>". You can view the detailed docs for this command here.

Orb のカテゴリ項目の表示

To see which categorizations have been applied an orb, check the output of circleci orb info <namespace>/<orb> for a list. You can view the detailed docs for this command here.

Orb の一覧表示

List your available orbs using the CLI:

To list public orbs:

circleci orb list <my-namespace>

To list private orbs:

circleci orb list <my-namespace> --private
