Repositories guide

Artifact Hub allows publishers to list their content in an automated way. Publishers can add their repositories from the control panel, accessible from the top right menu after signing in. It’s possible to create an organization and add repositories to it instead of adding them to the user’s account. Repositories will be indexed periodically to always display the most up-to-date content.

The following repositories kinds are supported at the moment:

This guide also contains additional information about the following repositories topics:

Verified publisher

Repositories and the packages they provide can display a special label named Verified publisher. This label indicates that the repository publisher owns or has control over the repository. Users may rely on it to decide if they want to use a given package or not.

Publishers can be verified through the artifacthub-repo.yml repository metadata file. In the repositories tab in the Artifact Hub control panel, the repository identifier is exposed on each repository’s card (ID). To proceed with the verification, an artifacthub-repo.yml metadata file must be added to the repository including that ID in the repositoryID field. The next time the repository is processed, the verification will be checked and the flag will be enabled if it succeeds.

Please note that the artifacthub-repo.yml metadata file must be located at the repository URL’s path. In Helm repositories, for example, this means it must be located at the same level of the chart repository index.yaml file, and it must be served from the chart repository HTTP server as well.

The verified publisher flag won’t be set until the next time the repository is processed. Please keep in mind that the repository won’t be processed if it hasn’t changed since the last time it was processed. Depending on the repository kind, this is checked in a different way. For Helm http based repositories, we consider it has changed if the index.yaml file changes (the generated field is ignored when performing this check). For git based repositories, it does when the hash of the last commit in the branch you set up changes.

Official status

In Artifact Hub, the official status means that the publisher owns the software deployed by a package. If we consider the example of a chart used to install Consul, to obtain the official status the publisher should be the owner of the Consul software (HashiCorp in this case), not just the chart.

The official status can be granted at the repository or package level. When it is granted for a repository, all packages available on it will display the official badge, so all packages in the repository must be official. If only some of the packages in your repository are official, please list them in the Official packages field when submitting the official status request.

Before applying for this status, please make sure your repository complies with the following requirements:

  • The repository has already obtained the Verified publisher status.
  • The user requesting the status is the publisher of the repository in Artifact Hub, or belongs to the organization publishing it.
  • All official packages available in the repository provide a README.md file with some documentation that can be displayed on Artifact Hub.

Once you have verified that the requirements are met, please file an issue using this template to apply.

Ownership claim

Any user is free to add any repository they wish to Artifact Hub. In some situations, legit owners may want to claim the ownership on an already published repository in order to publish it themselves. This process can be easily done in an automated way from the Artifact Hub control panel.

First, an artifacthub-repo.yml metadata file must be added to the repository you want to claim the ownership for. Only the owners section of the metadata file is required to be set up for this process. The repositoryID field can be omitted as the user claiming the ownership doesn’t know it yet. The user requesting the ownership claim must appear in the list of owners in the metadata file, and the email listed must match with the one used to sign in in Artifact Hub. This information will be used during the process to verify that the requesting user actually owns the repository.

Once the repository metadata file has been set up, you can proceed from the Artifact Hub control panel. In the repositories tab, click on Claim Ownership. You’ll need to enter the repository you’d like to claim the ownership for, as well as the destination entity, which can be the user performing the request or an organization. If the metadata file was set up correctly, the process should complete successfully.

Please note that the artifacthub-repo.yml metadata file must be located at the repository URL’s path. In Helm repositories, for example, this means it must be located at the same level of the chart repository index.yaml file, and it must be served from the chart repository HTTP server as well.

Private repositories

Artifact Hub supports adding private repositories (except OLM OCI based). By default this feature is disabled, but you can enable it in your own Artifact Hub deployment setting the hub.server.allowPrivateRepositories configuration setting to true. When enabled, you’ll be allowed to add the authentication credentials for the repository in the add/update repository modal in the control panel. Credentials are not exposed in the Artifact Hub UI, so users will need to get them separately. The installation instructions modal will display a warning to users when the package displayed belongs to a private repository.

Please note that this feature is not enabled in artifacthub.io.
