Configuring access to private registries for Dependabot

About private registries

Dependabot version updates keeps your dependencies up-to-date. Dependabot can access public registries. In addition, you can give Dependabot version updates access to private package registries and private GitHub repositories so that you can keep your private and innersource dependencies as up-to-date as your public dependencies.

In most ecosystems, private dependencies are usually published to private package registries. These private registries are similar to their public equivalents, but they require authentication.

Configuring private registries

You configure Dependabot's access to private registries in the dependabot.yml file. The top-level registries key is optional and specifies authentication details. 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.

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 "Configuring access to private registries for Dependabot."
key	A reference to a Dependabot secret containing an access key for this registry. For more information, see "Configuring access to private registries for Dependabot."
token	A reference to a Dependabot secret containing an access token for this registry. For more information, see "Configuring access to private registries 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).

For more information about the configuration options that are available, how to use them, and about the supported types, see "Configuration options for the dependabot.yml file."

Storing credentials for Dependabot to use

To give Dependabot access to the private registries supported by GitHub, you store the registry’s access token or secret in the secret store for your repository or organization.

About encrypted secrets for Dependabot

Dependabot secrets are encrypted credentials that you create at either the organization level or the repository level. When you add a secret at the organization level, you can specify which repositories can access the secret. You can use secrets to allow Dependabot to update dependencies located in private package registries. When you add a secret, it's encrypted before it reaches GitHub and it remains encrypted until it's used by Dependabot to access a private package registry.

Dependabot secrets also include secrets that are used by GitHub Actions workflows triggered by Dependabot pull requests. Dependabot itself may not use these secrets, but the workflows require them. For more information, see "Automating Dependabot with GitHub Actions."

After you add a Dependabot secret, you can reference it in the dependabot.yml configuration file like this: ${{secrets.NAME}}, where "NAME" is the name you chose for the secret. For example:

password: ${{secrets.MY_ARTIFACTORY_PASSWORD}}

For more information, see "Configuration options for the dependabot.yml file."
