Artifact Hub annotations in OLM operator CSV file
Artifact Hub uses the metadata in the operator’s
CSV file to populate the information for a package of kind OLM. Usually most of the information needed is already there, so there is no extra work required by maintainers to list them on Artifact Hub.
However, sometimes there might be cases in which it may be useful to provide some more context that helps improving users' experience in Artifact Hub. This can be done using some special annotations in the CSV file.
- artifacthub.io/changes (yaml string, see example below)
This annotation is used to provide some details about the changes introduced by a given operator version. Artifact Hub can generate and display a ChangeLog based on the entries in the
changes field in all your operator versions. You can see an example of how the changelog would look like in the Artifact Hub UI here.
This annotation can be provided using two different formats: using a plain list of strings with the description of the change or using a list of objects with some extra structured information (see example below). Please feel free to use the one that better suits your needs. The UI experience will be slightly different depending on the choice. When using the list of objects option the valid supported kinds are added, changed, deprecated, removed, fixed and security.
- artifacthub.io/containsSecurityUpdates (boolean string, see example below)
Use this annotation to indicate that this operator version contains security updates. When a package release contains security updates, a special message will be displayed in the Artifact Hub UI as well as in the new release email notification.
- artifacthub.io/imagesWhitelist (yaml string, see example below)
Use this annotation to provide a list of the images that should not be scanned for security vulnerabilities.
- artifacthub.io/install (yaml string, see example below)
This annotation can be used to provide custom installation instructions for your package. They must be in markdown format.
- artifacthub.io/license (string)
Use this annotation to indicate the operator’s license. It must be a valid SPDX identifier.
- artifacthub.io/prerelease (boolean string, see example below)
Use this annotation to indicate that this operator version is a pre-release. This status will be displayed in the UI’s package view, as well as in new releases notifications emails.
- artifacthub.io/recommendations (yaml string, see example below)
This annotation allows recommending other related packages. Recommended packages will be featured in the package detail view in Artifact Hub.
- artifacthub.io/screenshots (yaml string, see example below)
This annotation can be used to provide some screenshots that will be featured in the package detail view in Artifact Hub.
