Configuration options for the dependabot.yml file

Note: Dependabot security and version updates are currently in private beta and subject to change. Please contact your account management team for instructions on enabling Dependabot updates.

注: この機能を使用するには、サイト管理者が your GitHub Enterprise Server instanceの Dependabot updatesを設定する必要があります。詳細については、「企業に対する Dependabot の有効化」を参照してください。

About the dependabot.yml file

The Dependabot configuration file, dependabot.yml, uses YAML syntax. If you're new to YAML and want to learn more, see "Learn YAML in five minutes."

You must store this file in the .github directory of your repository. When you add or update the dependabot.yml file, this triggers an immediate check for version updates. For more information and an example, see "Configuring Dependabot version updates."

Any options that also affect security updates are used the next time a security alert triggers a pull request for a security update. For more information, see "Configuring Dependabot security updates."

Note: You cannot configure Dependabot alerts using the dependabot.yml file.

The dependabot.yml file has two mandatory top-level keys: version, and updates. You can, optionally, include a top-level registries key. The file must start with version: 2.

Configuration options for the dependabot.yml file

The top-level updates key is mandatory. You use it to configure how Dependabot updates the versions or your project's dependencies. Each entry configures the update settings for a particular package manager. You can use the following options.

オプション	必須	セキュリティ更新プログラム	バージョンアップデート	説明
`package-ecosystem`	X		X	使用するパッケージマネージャー
`directory`	X		X	パッケージマニフェストの場所
`schedule.interval`	X		X	更新を確認する頻度
`allow`		x	x	許可する更新をカスタマイズする
`assignees`		x	X	プルリクエストのアサイン担当者
`commit-message`		x	x	コミットメッセージの環境設定
`ignore`		x	x	特定の依存関係またはバージョンを無視する
`insecure-external-code-execution`			x	マニフェストファイル内でコードの実行を許可または拒否する
`labels`		x	x	プルリクエストに設定するラベル
`milestone`		X	x	プルリクエストに設定するマイルストーン
`open-pull-requests-limit`		x	x	バージョン更新時のオープンなプルリクエスト数を制限する
`pull-request-branch-name.separator`		x	x	プルリクエストブランチ名の区切り文字を変更する
`rebase-strategy`		x	x	自動リベースを無効にする
`registries`			x	Dependabot がアクセスできるプライベートリポジトリ
`reviewers`		x	x	プルリクエストのレビュー担当者
`schedule.day`			x	更新を確認する曜日
`schedule.time`			x	更新を確認する時刻 (hh:mm)
`schedule.timezone`			x	時刻のタイムゾーン（ゾーン識別子）
`target-branch`			x	プルリクエストを作成するブランチ
`vendor`			x	ベンダーまたはキャッシュされた依存関係を更新する
`versioning-strategy`		x	x	マニフェストのバージョン要件の更新方法

These options fit broadly into the following categories.

Essential set up options that you must include in all configurations: package-ecosystem, directory,schedule.interval.
Options to customize the update schedule: schedule.time, schedule.timezone, schedule.day.
Options to control which dependencies are updated: allow, ignore, vendor.
Options to add metadata to pull requests: reviewers, assignees, labels, milestone.
Options to change the behavior of the pull requests: target-branch, versioning-strategy, commit-message, rebase-strategy, pull-request-branch-name.separator.

In addition, the open-pull-requests-limit option changes the maximum number of pull requests for version updates that Dependabot can open.

Note: Some of these configuration options may also affect pull requests raised for security updates of vulnerable package manifests.

Security updates are raised for vulnerable package manifests only on the default branch. When configuration options are set for the same branch (true unless you use target-branch), and specify a package-ecosystem and directory for the vulnerable manifest, then pull requests for security updates use relevant options.

In general, security updates use any configuration options that affect pull requests, for example, adding metadata or changing their behavior. For more information about security updates, see "Configuring Dependabot security updates."

`package-ecosystem`

Required. You add one package-ecosystem element for each package manager that you want Dependabot to monitor for new versions. The repository must also contain a dependency manifest or lock file for each of these package managers. If you want to enable vendoring for a package manager that supports it, the vendored dependencies must be located in the required directory. For more information, see vendor below.

The following table shows, for each package manager:

The YAML value to use in the dependabot.yml file
The supported versions of the package manager
Whether dependencies in private GitHub repositories or registries are supported
Whether vendored dependencies are supported

Package manager	YAML value	Supported versions	Private repositories	Private registries	Vendoring
Bundler	`bundler`	v1, v2		✓	✓
Cargo	`cargo`	v1	✓	✓
Composer	`composer`	v1, v2	✓	✓
Docker	`docker`	v1	✓	✓
Hex	`mix`	v1		✓
elm-package	`elm`	v0.19	✓	✓

Go modules	`gomod`	v1	✓	✓	✓
Gradle	`gradle`	N/A (no version)^[2]	✓	✓
Maven	`maven`	N/A (no version)^[3]	✓	✓
npm	`npm`	v6, v7, v8	✓	✓
NuGet	`nuget`	<= 4.8^[4]	✓	✓
pip	`pip`	v21.1.2		✓
pipenv	`pip`	<= 2021-05-29		✓

poetry	`pip`	v1		✓
Terraform	`terraform`	>= 0.13, <= 1.2.x	✓	✓
yarn	`npm`	v1	✓	✓

Tip: For package managers such as pipenv and poetry, you need to use the pip YAML value. For example, if you use poetry to manage your Python dependencies and want Dependabot to monitor your dependency manifest file for new versions, use package-ecosystem: "pip" in your dependabot.yml file.

[2] Dependabot doesn't run Gradle but supports updates to the following files: build.gradle, build.gradle.kts (for Kotlin projects), and files included via the apply declaration that have dependencies in the filename. Note that apply does not support apply to, recursion, or advanced syntaxes (for example, Kotlin's apply with mapOf, filenames defined by property).

[3] Dependabot doesn't run Maven but supports updates to pom.xml files.

[4] Dependabot doesn't run the NuGet CLI but does support most features up until version 4.8.

# Basic set up for three package managers

version: 2
updates:

  # Maintain dependencies for GitHub Actions
  - package-ecosystem: "github-actions"
    directory: "/"
    schedule:
      interval: "weekly"

  # Maintain dependencies for npm
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"

  # Maintain dependencies for Composer
  - package-ecosystem: "composer"
    directory: "/"
    schedule:
      interval: "weekly"

`directory`

Required. You must define the location of the package manifests for each package manager (for example, the package.json or Gemfile). You define the directory relative to the root of the repository for all ecosystems except GitHub Actions. For GitHub Actions, set the directory to / to check for workflow files in .github/workflows.

# Specify location of manifest files for each package manager

version: 2
updates:
  - package-ecosystem: "composer"
    # Files stored in repository root
    directory: "/"
    schedule:
      interval: "weekly"

  - package-ecosystem: "npm"
    # Files stored in `app` directory
    directory: "/app"
    schedule:
      interval: "weekly"

  - package-ecosystem: "github-actions"
    # Workflow files stored in the
    # default location of `.github/workflows`
    directory: "/"
    schedule:
      interval: "weekly"

`schedule.interval`

Required. You must define how often to check for new versions for each package manager. By default, Dependabot randomly assigns a time to apply all the updates in the configuration file. To set a specific time, you can use schedule.time and schedule.timezone.

Interval types	Frequency
`daily`	Runs on every weekday, Monday to Friday.
`weekly`	Runs once each week. By default, this is on Monday. To modify this, use `schedule.day`.
`monthly`	Runs once each month. This is on the first day of the month.

# Set update schedule for each package manager

version: 2
updates:

  - package-ecosystem: "github-actions"
    directory: "/"
    schedule:
      # Check for updates to GitHub Actions every weekday
      interval: "daily"

  - package-ecosystem: "composer"
    directory: "/"
    schedule:
      # Check for updates managed by Composer once a week
      interval: "weekly"

Note: schedule defines when Dependabot attempts a new update. However, it's not the only time you may receive pull requests. Updates can be triggered based on changes to your dependabot.yml file, changes to your manifest file(s) after a failed update, or Dependabot security updates. For more information, see "Frequency of Dependabot pull requests" and "About Dependabot security updates."

`allow`

By default all dependencies that are explicitly defined in a manifest are kept up to date by Dependabot version updates. In addition, Dependabot security updates also update vulnerable dependencies that are defined in lock files. You can use allow and ignore to customize which dependencies to maintain. Dependabot checks for all allowed dependencies and then filters out any ignored dependencies or versions. So a dependency that is matched by both an allow and an ignore will be ignored.

Use the allow option to customize which dependencies are updated. This applies to both version and security updates. You can use the following options:

dependency-name—use to allow updates for dependencies with matching names, optionally using * to match zero or more characters. For Java dependencies, the format of the dependency-name attribute is: groupId:artifactId, for example: org.kohsuke:github-api.

dependency-type—use to allow updates for dependencies of specific types.

Dependency types	Supported by package managers	Allow updates
`direct`	All	All explicitly defined dependencies.
`indirect`	`bundler`, `pip`, `composer`, `cargo`	Dependencies of direct dependencies (also known as sub-dependencies, or transient dependencies).
`all`	All	All explicitly defined dependencies. For `bundler`, `pip`, `composer`, `cargo`, also the dependencies of direct dependencies.
`production`	`bundler`, `composer`, `mix`, `maven`, `npm`, `pip`	Only dependencies in the "Production dependency group".
`development`	`bundler`, `composer`, `mix`, `maven`, `npm`, `pip`	Only dependencies in the "Development dependency group".

# Use `allow` to specify which dependencies to maintain

version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    allow:
      # Allow updates for Lodash
      - dependency-name: "lodash"
      # Allow updates for React and any packages starting "react"
      - dependency-name: "react*"

  - package-ecosystem: "composer"
    directory: "/"
    schedule:
      interval: "weekly"
    allow:
      # Allow both direct and indirect updates for all packages
      - dependency-type: "all"

  - package-ecosystem: "pip"
    directory: "/"
    schedule:
      interval: "weekly"
    allow:
      # Allow only direct updates for
      # Django and any packages starting "django"
      - dependency-name: "django*"
        dependency-type: "direct"
      # Allow only production updates for Sphinx
      - dependency-name: "sphinx"
        dependency-type: "production"

`assignees`

Use assignees to specify individual assignees for all pull requests raised for a package manager.

target-branch を使って既定以外のブランチのバージョンアップデートをチェックしないかぎり、このオプションの設定も、このパッケージマネージャーのマニフェストファイルに対するセキュリティ更新プログラムの pull request に影響します。

# Specify assignees for pull requests

version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    # Add assignees
    assignees:
      - "octocat"

`commit-message`

By default, Dependabot attempts to detect your commit message preferences and use similar patterns. Use the commit-message option to specify your preferences explicitly.

Supported options

Note: The prefix and the prefix-development options have a 15 character limit.

prefix specifies a prefix for all commit messages.
prefix-development specifies a separate prefix for all commit messages that update dependencies in the Development dependency group. When you specify a value for this option, the prefix is used only for updates to dependencies in the Production dependency group. This is supported by: bundler, composer, mix, maven, npm, and pip.
include: "scope" specifies that any prefix is followed by a list of the dependencies updated in the commit.

# Customize commit messages

version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    commit-message:
      # Prefix all commit messages with "npm"
      prefix: "npm"

  - package-ecosystem: "composer"
    directory: "/"
    schedule:
      interval: "weekly"
    # Prefix all commit messages with "Composer"
    # include a list of updated dependencies
    commit-message:
      prefix: "Composer"
      include: "scope"

  - package-ecosystem: "pip"
    directory: "/"
    schedule:
      interval: "weekly"
    # Include a list of updated dependencies
    # with a prefix determined by the dependency group
    commit-message:
      prefix: "pip prod"
      prefix-development: "pip dev"
      include: "scope"

If you use the same configuration as in the example above, bumping the requests library in the pip development dependency group will generate a commit message of:

pip dev: bump requests from 1.0.0 to 1.0.1

`ignore`

By default all dependencies that are explicitly defined in a manifest are kept up to date by Dependabot version updates. In addition, Dependabot security updates also update vulnerable dependencies that are defined in lock files. You can use allow and ignore to customize which dependencies to maintain. Dependabot checks for all allowed dependencies and then filters out any ignored dependencies or versions. So a dependency that is matched by both an allow and an ignore will be ignored.

Dependencies can be ignored either by adding them to ignore or by using the @dependabot ignore command on a pull request opened by Dependabot.

Creating `ignore` conditions from `@dependabot ignore`

Dependencies ignored by using the @dependabot ignore command are stored centrally for each package manager. If you start ignoring dependencies in the dependabot.yml file, these existing preferences are considered alongside the ignore dependencies in the configuration.

You can check whether a repository has stored ignore preferences by searching the repository for "@dependabot ignore" in:comments. If you wish to un-ignore a dependency ignored this way, re-open the pull request.

For more information about the @dependabot ignore commands, see "Managing pull requests for dependency updates."

Specifying dependencies and versions to ignore

You can use the ignore option to customize which dependencies are updated. The ignore option supports the following options.

dependency-name—use to ignore updates for dependencies with matching names, optionally using * to match zero or more characters. For Java dependencies, the format of the dependency-name attribute is: groupId:artifactId (for example: org.kohsuke:github-api).
versions—use to ignore specific versions or ranges of versions. If you want to define a range, use the standard pattern for the package manager (for example: ^1.0.0 for npm, or ~> 2.0 for Bundler).
update-types—use to ignore types of updates, such as semver major, minor, or patch updates on version updates (for example: version-update:semver-patch will ignore patch updates). You can combine this with dependency-name: "*" to ignore particular update-types for all dependencies. Currently, version-update:semver-major, version-update:semver-minor, and version-update:semver-patch are the only supported options. Security updates are unaffected by this setting.

If versions and update-types are used together, Dependabot will ignore any update in either set.

target-branch を使って既定以外のブランチのバージョンアップデートをチェックしないかぎり、このオプションの設定も、このパッケージマネージャーのマニフェストファイルに対するセキュリティ更新プログラムの pull request に影響します。

# Use `ignore` to specify dependencies that should not be updated

version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    ignore:
      - dependency-name: "express"
        # For Express, ignore all updates for version 4 and 5
        versions: ["4.x", "5.x"]
        # For Lodash, ignore all updates
      - dependency-name: "lodash"
        # For AWS SDK, ignore all patch updates
      - dependency-name: "aws-sdk"
        update-types: ["version-update:semver-patch"]

Note: Dependabot can only run version updates on manifest or lock files if it can access all of the dependencies in the file, even if you add inaccessible dependencies to the ignore option of your configuration file. For more information, see "Managing security and analysis settings for your organization" and "Troubleshooting Dependabot errors."

`insecure-external-code-execution`

Package managers with the package-ecosystem values bundler, mix, and pip may execute external code in the manifest as part of the version update process. This might allow a compromised package to steal credentials or gain access to configured registries. When you add a registries setting within an updates configuration, Dependabot automatically prevents external code execution, in which case the version update may fail. You can choose to override this behavior and allow external code execution for bundler, mix, and pip package managers by setting insecure-external-code-execution to allow.

You can explicitly deny external code execution, irrespective of whether there is a registries setting for this update configuration, by setting insecure-external-code-execution to deny.

# Allow external code execution when updating dependencies from private registries

version: 2
registries:
  ruby-github:
    type: rubygems-server
    url: https://rubygems.pkg.github.com/octocat/github_api
    token: ${{secrets.MY_GITHUB_PERSONAL_TOKEN}}
updates:
  - package-ecosystem: "bundler"
    directory: "/rubygems-server"
    insecure-external-code-execution: allow
    registries: "*"
    schedule:
      interval: "monthly"

`labels`

既定では、Dependabot ではすべての pull request を dependencies ラベル付きで発行します。複数のパッケージマネージャが定義されている場合、DependabotはそれぞれのPull Requestに追加のラベルを含めます。これは、その pull request によってどの言語またはエコシステムが更新されるかを示します。たとえば、Gradle の更新には java、Git サブモジュールの更新には submodules というようになります。 Dependabotは、リポジトリ中の必要に応じて自動的にこれらのデフォルトラベルを作成します。

Use labels to override the default labels and specify alternative labels for all pull requests raised for a package manager. If any of these labels is not defined in the repository, it is ignored. To disable all labels, including the default labels, use labels: [ ].

target-branch を使って既定以外のブランチのバージョンアップデートをチェックしないかぎり、このオプションの設定も、このパッケージマネージャーのマニフェストファイルに対するセキュリティ更新プログラムの pull request に影響します。

# Specify labels for pull requests

    schedule:
      interval: "weekly"
    # Specify labels for npm pull requests
    labels:
      - "npm"
      - "dependencies"

`milestone`

Use milestone to associate all pull requests raised for a package manager with a milestone. You need to specify the numeric identifier of the milestone and not its label. If you view a milestone, the final part of the page URL, after milestone, is the identifier. For example: https://github.com/<org>/<repo>/milestone/3.

updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    # Associate pull requests with milestone "4"
    milestone: 4

`open-pull-requests-limit`

By default, Dependabot opens a maximum of five pull requests for version updates. Once there are five open pull requests from Dependabot, Dependabot will not open any new requests until some of those open requests are merged or closed. Use open-pull-requests-limit to change this limit. This also provides a simple way to temporarily disable version updates for a package manager.

This option has no impact on security updates, which have a separate, internal limit of ten open pull requests.

# Specify the number of open pull requests allowed

version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    # Disable version updates for npm dependencies
    open-pull-requests-limit: 0

  - package-ecosystem: "pip"
    directory: "/"
    schedule:
      interval: "weekly"
    # Allow up to 10 open pull requests for pip dependencies
    open-pull-requests-limit: 10

`pull-request-branch-name.separator`

Dependabot generates a branch for each pull request. Each branch name includes dependabot, and the package manager and dependency that are updated. By default, these parts are separated by a / symbol, for example: dependabot/npm_and_yarn/next_js/acorn-6.4.1.

Use pull-request-branch-name.separator to specify a different separator. This can be one of: "-", _ or /. The hyphen symbol must be quoted because otherwise it's interpreted as starting an empty YAML list.

target-branch を使って既定以外のブランチのバージョンアップデートをチェックしないかぎり、このオプションの設定も、このパッケージマネージャーのマニフェストファイルに対するセキュリティ更新プログラムの pull request に影響します。

# Specify a different separator for branch names

version: 2

    schedule:
      interval: "weekly"
    pull-request-branch-name:
      # Separate sections of the branch name with a hyphen
      # for example, `dependabot-npm_and_yarn-next_js-acorn-6.4.1`
      separator: "-"

`rebase-strategy`

By default, Dependabot automatically rebases open pull requests when it detects any changes to the pull request. Use rebase-strategy to disable this behavior.

Available rebase strategies

auto to use the default behavior and rebase open pull requests when changes are detected.
disabled to disable automatic rebasing.

When rebase-strategy is set to auto, Dependabot attempts to rebase pull requests in the following cases.

When you use Dependabot version updates, for any open Dependabot pull request when your schedule runs.
When you reopen a closed Dependabot pull request.
When you change the value of target-branch in the Dependabot configuration file. For more information about this field, see "target-branch."
When Dependabot detects that a Dependabot pull request is in conflict after a recent push to the target branch.

Note: Dependabot will keep rebasing a pull request indefinitely until the pull request is closed, merged or you disable Dependabot updates.

When rebase-strategy is set to disabled, Dependabot stops rebasing pull requests.

Note: This behavior only applies to pull requests that go into conflict with the target branch. Dependabot will keep rebasing pull requests opened prior to the rebase-strategy setting being changed, and pull requests that are part of a scheduled run.

    directory: "/"
    schedule:
      interval: "weekly"
    # Disable rebasing for npm pull requests
    rebase-strategy: "disabled"

`registries`

To allow Dependabot to access a private package registry when performing a version update, you must include a registries setting within the relevant updates configuration. You can allow all of the defined registries to be used by setting registries to "*". Alternatively, you can list the registries that the update can use. To do this, use the name of the registry as defined in the top-level registries section of the dependabot.yml file. For more information, see "Configuration options for private registries" below.

To allow Dependabot to use bundler, mix, and pip package managers to update dependencies in private registries, you can choose to allow external code execution. For more information, see insecure-external-code-execution above.

# Allow Dependabot to use one of the two defined private registries
# when updating dependency versions for this ecosystem

version: 2
registries:
  maven-github:
    type: maven-repository
    url: https://maven.pkg.github.com/octocat

    schedule:
      interval: "monthly"

`reviewers`

Use reviewers to specify individual reviewers or teams of reviewers for all pull requests raised for a package manager. You must use the full team name, including the organization, as if you were @mentioning the team.

target-branch を使って既定以外のブランチのバージョンアップデートをチェックしないかぎり、このオプションの設定も、このパッケージマネージャーのマニフェストファイルに対するセキュリティ更新プログラムの pull request に影響します。

    reviewers:
      - "octocat"
      - "my-username"
      - "my-org/python-team"

`schedule.day`

When you set a weekly update schedule, by default, Dependabot checks for new versions on Monday at a random set time for the repository. Use schedule.day to specify an alternative day to check for updates.

Supported values

monday
tuesday
wednesday
thursday
friday
saturday
sunday

# Specify the day for weekly checks

version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
      # Check for npm updates on Sundays
      day: "sunday"

`schedule.time`

By default, Dependabot checks for new versions at a random set time for the repository. Use schedule.time to specify an alternative time of day to check for updates (format: hh:mm).

# Set a time for checks
version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
      # Check for npm updates at 9am UTC
      time: "09:00"

`schedule.timezone`

By default, Dependabot checks for new versions at a random set time for the repository. Use schedule.timezone to specify an alternative time zone. The time zone identifier must be from the Time Zone database maintained by iana. For more information, see List of tz database time zones.

# Specify the timezone for checks

version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
      time: "09:00"
      # Use Japan Standard Time (UTC +09:00)
      timezone: "Asia/Tokyo"

`target-branch`

By default, Dependabot checks for manifest files on the default branch and raises pull requests for version updates against this branch. Use target-branch to specify a different branch for manifest files and for pull requests. When you use this option, the settings for this package manager will no longer affect any pull requests raised for security updates.

# Specify a non-default branch for pull requests for pip

version: 2
updates:
  - package-ecosystem: "pip"
    directory: "/"
    schedule:
      interval: "weekly"
    # Raise pull requests for version updates
    # to pip against the `develop` branch
    target-branch: "develop"
    # Labels on pull requests for version updates only
    labels:
      - "pip dependencies"

  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
      # Check for npm updates on Sundays
      day: "sunday"
    # Labels on pull requests for security and version updates
    labels:
      - "npm dependencies"

`vendor`

Use the vendor option to tell Dependabot to vendor dependencies when updating them. Don't use this option if you're using gomod as Dependabot automatically detects vendoring for this tool.

# Configure version updates for both dependencies defined in manifests and vendored dependencies

version: 2
updates:
  - package-ecosystem: "bundler"
    # Raise pull requests to update vendored dependencies that are checked in to the repository
    vendor: true
    directory: "/"
    schedule:
      interval: "weekly"

Dependabot only updates the vendored dependencies located in specific directories in a repository.

Package manager	Required file path for vendored dependencies	More information
`bundler`	The dependencies must be in the vendor/cache directory. Other file paths are not supported.	`bundle cache` documentation
`gomod`	No path requirement (dependencies are usually located in the vendor directory)	`go mod vendor` documentation

`versioning-strategy`

When Dependabot edits a manifest file to update a version, it uses the following overall strategies:

For apps, the version requirements are increased, for example: npm, pip and Composer.
For libraries, the range of versions is widened, for example: Bundler and Cargo.

Use the versioning-strategy option to change this behavior for supported package managers.

target-branch を使って既定以外のブランチのバージョンアップデートをチェックしないかぎり、このオプションの設定も、このパッケージマネージャーのマニフェストファイルに対するセキュリティ更新プログラムの pull request に影響します。

Available update strategies

Option	Supported by	Action
`lockfile-only`	`bundler`, `cargo`, `composer`, `mix`, `npm`, `pip`	Only create pull requests to update lockfiles. Ignore any new versions that would require package manifest changes.
`auto`	`bundler`, `cargo`, `composer`, `mix`, `npm`, `pip`	Follow the default strategy described above.
`widen`	`composer`, `npm`	Relax the version requirement to include both the new and old version, when possible.
`increase`	`bundler`, `composer`, `npm`	Always increase the version requirement to match the new version.
`increase-if-necessary`	`bundler`, `composer`, `npm`	Increase the version requirement only when required by the new version.

# Customize the manifest version strategy

version: 2
updates:
  - package-ecosystem: "npm"
    directory: "/"
    schedule:
      interval: "weekly"
    # Update the npm manifest file to relax
    # the version requirements
    versioning-strategy: widen

  - package-ecosystem: "composer"
    directory: "/"
    schedule:
      interval: "weekly"
    # Increase the version requirements for Composer
    # only when required
    versioning-strategy: increase-if-necessary

  - package-ecosystem: "pip"
    directory: "/"
    schedule:
      interval: "weekly"
    # Only allow updates to the lockfile for pip and
    # ignore any version updates that affect the manifest
    versioning-strategy: lockfile-only

Configuration options for private registries

The top-level registries key is optional. It allows you to specify authentication details that Dependabot can use to access private package registries.

Note: Private registries behind firewalls on private networks are not supported.

The value of the registries key is an associative array, each element of which consists of a key that identifies a particular registry and a value which is an associative array that specifies the settings required to access that registry. The following dependabot.yml file, configures a registry identified as dockerhub in the registries section of the file and then references this in the updates section of the file.

# Minimal settings to update dependencies in one private registry

version: 2
registries:
  dockerhub: # Define access for a private registry
    type: docker-registry
    url: registry.hub.docker.com
    username: octocat
    password: ${{secrets.DOCKERHUB_PASSWORD}}
updates:
  - package-ecosystem: "docker"
    directory: "/docker-registry/dockerhub"
    registries:
      - dockerhub # Allow version updates for dependencies in this registry
    schedule:
      interval: "monthly"

You use the following options to specify access settings. Registry settings must contain a type and a url, and typically either a username and password combination or a token.

Option	Description
`type`	Identifies the type of registry. See the full list of types below.
`url`	The URL to use to access the dependencies in this registry. The protocol is optional. If not specified, `https://` is assumed. Dependabot adds or ignores trailing slashes as required.
`username`	The username that Dependabot uses to access the registry.
`password`	A reference to a Dependabot secret containing the password for the specified user. For more information, see "Managing encrypted secrets for Dependabot."
`key`	A reference to a Dependabot secret containing an access key for this registry. For more information, see "Managing encrypted secrets for Dependabot."
`token`	A reference to a Dependabot secret containing an access token for this registry. For more information, see "Managing encrypted secrets for Dependabot."
`replaces-base`	For registries with `type: python-index`, if the boolean value is `true`, pip resolves dependencies by using the specified URL rather than the base URL of the Python Package Index (by default `https://pypi.org/simple`).

Each configuration type requires you to provide particular settings. Some types allow more than one way to connect. The following sections provide details of the settings you should use for each type.

`composer-repository`

The composer-repository type supports username and password.

registries:
  composer:
    type: composer-repository
    url: https://repo.packagist.com/example-company/
    username: octocat
    password: ${{secrets.MY_PACKAGIST_PASSWORD}}

`docker-registry`

Dependabot works with any container registries that implement the OCI container registry spec. For more information, see https://github.com/opencontainers/distribution-spec/blob/main/spec.md. Dependabot supports authentication to private registries via a central token service or HTTP Basic Auth. For further details, see Token Authentication Specification in the Docker documentation and Basic access authentication on Wikipedia.

The docker-registry type supports username and password.

registries:
  dockerhub:
