Configuration options for the dependabot.yml file

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."

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.

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.

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

[1] Dependabot can update Docker image tags in Kubernetes manifests. Add an entry to the Docker package-ecosystem element of your dependabot.yml file for each directory containing a Kubernetes manifest which references Docker image tags. Kubernetes manifests can be Kubernetes Deployment YAML files or Helm charts. For information about configuring your dependabot.yml file for docker, see "package-ecosystem" in "Configuration options for the dependabot.yml file."

Dependabot supports both public and private Docker registries. For a list of the supported registries, see "docker-registry" in "Configuration options for the 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.

[5] In addition to supporting updates to requirements.txt files, Dependabot supports updates to pyproject.toml files if they follow the PEP 621 standard.

[6] Dependabot won't perform an update for pub when the version that it tries to update to is ignored, even if an earlier version is available.

[7] Dependabot supports vendored dependencies for v2 onwards.

# 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"

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

    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

• 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

  - 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). To prevent Dependabot from automatically updating TypeScript type definitions from DefinitelyTyped, use @types/*.
• 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.

# 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"]

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:

    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: [ ].

    # 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.

    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.

    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.

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

    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

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.

    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.

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.

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:
    type: docker-registry
    url: https://registry.hub.docker.com
    username: octocat
    password: ${{secrets.MY_DOCKERHUB_PASSWORD}}

The docker-registry type can also be used to pull from private Amazon ECR using static AWS credentials.

registries:
  ecr-docker:
    type: docker-registry
    url: https://1234567890.dkr.ecr.us-east-1.amazonaws.com
    username: ${{secrets.ECR_AWS_ACCESS_KEY_ID}}
    password: ${{secrets.ECR_AWS_SECRET_ACCESS_KEY}}

git

The git type supports username and password.

registries:
  github-octocat:
    type: git
    url: https://github.com
    username: x-access-token
    password: ${{secrets.MY_GITHUB_PERSONAL_TOKEN}}

hex-organization

The hex-organization type supports organization and key.

registries:
  github-hex-org:
    type: hex-organization
    organization: github
    key: ${{secrets.MY_HEX_ORGANIZATION_KEY}}

hex-repository

The hex-repository type supports an authentication key.

repo is a required field, which must match the name of the repository used in your dependency declaration.

The public-key-fingerprint is an optional configuration field, representing the fingerprint of the public key for the Hex repository. public-key-fingerprint is used by Hex to establish trust with the private repository. The public-key-fingerprint field can be either listed in plaintext or stored as a Dependabot secret.

registries:
   github-hex-repository:
     type: hex-repository
     repo: private-repo
     url: https://private-repo.example.com
     auth-key: ${{secrets.MY_AUTH_KEY}}
     public-key-fingerprint: ${{secrets.MY_PUBLIC_KEY_FINGERPRINT}}

maven-repository

The maven-repository type supports username and password.

registries:
  maven-artifactory:
    type: maven-repository
    url: https://artifactory.example.com
    username: octocat
    password: ${{secrets.MY_ARTIFACTORY_PASSWORD}}

npm-registry

The npm-registry type supports username and password, or token.

When using username and password, your .npmrc's auth token may contain a base64 encoded _password; however, the password referenced in your Dependabot configuration file must be the original (unencoded) password.

registries:
  npm-npmjs:
    type: npm-registry
    url: https://registry.npmjs.org
    username: octocat
    password: ${{secrets.MY_NPM_PASSWORD}}  # Must be an unencoded password

registries:
  npm-github:
    type: npm-registry
    url: https://npm.pkg.github.com
    token: ${{secrets.MY_GITHUB_PERSONAL_TOKEN}}

For security reasons, Dependabot does not set environment variables. Yarn (v2 and later) requires that any accessed environment variables are set. When accessing environment variables in your .yarnrc.yml file, you should provide a fallback value such as ${ENV_VAR-fallback} or ${ENV_VAR:-fallback}. For more information, see Yarnrc files in the Yarn documentation.

nuget-feed

The nuget-feed type supports username and password, or token.

registries:
  nuget-example:
    type: nuget-feed
    url: https://nuget.example.com/v3/index.json
    username: octocat@example.com
    password: ${{secrets.MY_NUGET_PASSWORD}}

registries:
  nuget-azure-devops:
    type: nuget-feed
    url: https://pkgs.dev.azure.com/.../_packaging/My_Feed/nuget/v3/index.json
    username: octocat@example.com
    password: ${{secrets.MY_AZURE_DEVOPS_TOKEN}}
