Note: Your site administrator must set up Dependabot updates for your GitHub Enterprise Server instance before you can use this feature. For more information, see "Enabling Dependabot for your enterprise."
You may not be able to enable or disable Dependabot updates if an enterprise owner has set a policy at the enterprise level. For more information, see "Enforcing policies for code security and analysis for your enterprise."
About Dependabot version updates
Dependabot takes the effort out of maintaining your dependencies. You can use it to ensure that your repository automatically keeps up with the latest releases of the packages and applications it depends on.
You enable Dependabot version updates by checking a dependabot.yml configuration file into your repository. The configuration file specifies the location of the manifest, or of other package definition files, stored in your repository. Dependabot uses this information to check for outdated packages and applications. Dependabot determines if there is a new version of a dependency by looking at the semantic versioning (semver) of the dependency to decide whether it should update to that version. For certain package managers, Dependabot version updates also supports vendoring. Vendored (or cached) dependencies are dependencies that are checked in to a specific directory in a repository rather than referenced in a manifest. Vendored dependencies are available at build time even if package servers are unavailable. Dependabot version updates can be configured to check vendored dependencies for new versions and update them if necessary.
When Dependabot identifies an outdated dependency, it raises a pull request to update the manifest to the latest version of the dependency. For vendored dependencies, Dependabot raises a pull request to replace the outdated dependency with the new version directly. You check that your tests pass, review the changelog and release notes included in the pull request summary, and then merge it. For more information, see "Configuring Dependabot version updates."
If you enable security updates, Dependabot also raises pull requests to update vulnerable dependencies. For more information, see "About Dependabot security updates."
When Dependabot raises pull requests, these pull requests could be for security or version updates:
- Dependabot security updates are automated pull requests that help you update dependencies with known vulnerabilities.
- Dependabot version updates are automated pull requests that keep your dependencies updated, even when they don’t have any vulnerabilities. To check the status of version updates, navigate to the Insights tab of your repository, then Dependency Graph, and Dependabot.
Dependabot signs its own commits by default, even if commit signing is not a requirement for the repository. For more information about verified commits, see "About commit signature verification."
Before you enable Dependabot updates, you must configure your GitHub Enterprise Server instance to use GitHub Actions with self-hosted runners. GitHub Actions is required for Dependabot version updates and Dependabot security updates to run on GitHub Enterprise Server. For more information, see "Enabling Dependabot for your enterprise."
Frequency of Dependabot pull requests
You specify how often to check each ecosystem for new versions in the configuration file: daily, weekly, or monthly.
When you first enable version updates, you may have many dependencies that are outdated and some may be many versions behind the latest version. Dependabot checks for outdated dependencies as soon as it's enabled. You may see new pull requests for version updates within minutes of adding the configuration file, depending on the number of manifest files for which you configure updates. Dependabot will also run an update on subsequent changes to the configuration file.
Dependabot may also create pull requests when you change a manifest file after an update has failed. This is because changes to a manifest, such as removing the dependency that caused the update to fail, may cause the newly triggered update to succeed.
To keep pull requests manageable and easy to review, Dependabot raises a maximum of five pull requests to start bringing dependencies up to the latest version. If you merge some of these first pull requests before the next scheduled update, remaining pull requests will be opened on the next update, up to that maximum. You can change the maximum number of open pull requests by setting the open-pull-requests-limit configuration option.
For more information, see "Customizing dependency updates."
If you've enabled security updates, you'll sometimes see extra pull requests for security updates. These are triggered by a Dependabot alert for a dependency on your default branch. Dependabot automatically raises a pull request to update the vulnerable dependency.
Supported repositories and ecosystems
You can configure version updates for repositories that contain a dependency manifest or lock file for one of the supported package managers. For some package managers, you can also configure vendoring for dependencies. For more information, see vendor.
Dependabot also supports dependencies in private registries. For more information, see registries.
Note: To ensure that GitHub Enterprise Server supports Dependabot updates for the latest supported ecosystem versions, your enterprise owner must download the most recent version of the Dependabot action. For more information about the action, and for instructions about how to download the most recent version, see "Using the latest version of the official bundled actions."
Note: When running security or version updates, some ecosystems must be able to resolve all dependencies from their source to verify that updates have been successful. If your manifest or lock files contain any private dependencies, Dependabot must be able to access the location at which those dependencies are hosted. Organization owners can grant Dependabot access to private repositories containing dependencies for a project within the same organization. For more information, see "Managing security and analysis settings for your organization." You can configure access to private registries in a repository's dependabot.yml configuration file. For more information, see "Configuration options for the dependabot.yml file."
Dependabot doesn't support private GitHub dependencies for all package managers. See the details in the table below.
The following table shows, for each package manager:
- The YAML value to use in the
dependabot.ymlfile - 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 | (Git only) | ||
| Composer | composer | v1, v2 | |||
| Docker | docker | v1 | Not applicable | ||
| Hex | mix | v1 | |||
| elm-package | elm | v0.19 | |||
| git submodule | gitsubmodule | Not applicable | Not applicable | ||
| GitHub Actions | github-actions | Not applicable | Not applicable | ||
| Go modules | gomod | v1 | |||
| Gradle | gradle | Not applicable | |||
| Maven | maven | Not applicable | |||
| npm | npm | v6, v7, v8, v9 | |||
| NuGet | nuget | <= 4.8 | |||
| pip | pip | v21.1.2 | |||
| pipenv | pip | <= 2021-05-29 | |||

| Terraform | terraform | >= 0.13, <= 1.8.x | Not applicable | ||
| yarn | npm | v1, v2, v3 |
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.
Cargo
Private registry support applies to Git registries, and doesn't include cargo registries.
Docker
Dependabot can add metadata from Docker images to pull requests for version updates. The metadata includes release notes, changelogs and the commit history. Repository administrators can use the metadata to quickly evaluate the stability risk of the dependency update.
In order for Dependabot to fetch Docker metadata, maintainers of Docker images must add the org.opencontainers.image.source label to their Dockerfile, and include the URL of the source repository. Additionally, maintainers must tag the repository with the same tags as the published Docker images. For an example, see the dependabot-fixtures/docker-with-source repository. For more information on Docker labels, see Extension image labels and BUILDX_GIT_LABELS in the Docker documentation.
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."
Dependabot parses Docker image tags for Semantic Versioning (SemVer). If Dependabot detects a tag with a pre-release, then it will only suggest an update to the latest version with a matching pre-release, and it will not suggest a newer version that use a different pre-release label. For more information, see the dependabot-docker README.md file in the dependabot/dependabot-core repository.
GitHub Actions
Dependabot supports version updates for GitHub Actions with the following caveats.
- Dependabot only supports updates to GitHub Actions using the GitHub repository syntax, such as
actions/checkout@v4. Dependabot will ignore actions or reusable workflows referenced locally (for example,./.github/actions/foo.yml). - Docker Hub and GitHub Packages Container registry URLs are currently not supported. For example, references to Docker container actions using
docker://syntax aren't supported. - Dependabot supports both public and private repositories for GitHub Actions. For private registry configuration options, see "
git" in "Configuration options for the dependabot.yml file."
For more information about using Dependabot version updates with GitHub Actions, see "Using GitHub's security features to secure your use of GitHub Actions."
Gradle
Gradle is supported for Dependabot version updates only.
Dependabot doesn't run Gradle but supports updates to the following files:
build.gradle,build.gradle.kts(for Kotlin projects)gradle/libs.versions.toml(for projects using a standard Gradle version catalog)- Files included via the
applydeclaration that havedependenciesin the filename. Note thatapplydoes not supportapply to, recursion, or advanced syntaxes (for example, Kotlin'sapplywithmapOf, filenames defined by property).
Maven
Dependabot doesn't run Maven but supports updates to pom.xml files.
NuGet CLI
Dependabot doesn't run the NuGet CLI but does support most features up until version 4.8.
pip and pip-compile
In addition to supporting updates to requirements.txt files, Dependabot supports updates to pyproject.toml files if they follow the PEP 621 standard.
pnpm
pnpm is supported for Dependabot version updates only. Dependabot security updates are not currently supported.
pub
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.
Terraform
Terraform support includes:
- Modules hosted on Terraform Registry or a publicly reachable Git repository.
- Terraform providers.
- Private Terraform Registry. You can configure access for private git repositories by specifying a git registry in your
dependabot.ymlfile. For more information, seegit.
yarn
Dependabot supports vendored dependencies for v2 onwards.
If your repository already uses an integration for dependency management, you will need to disable this before enabling Dependabot.
