Artifact Hub annotations in Tekton manifest file
Artifact Hub uses some data from the
Tekton manifest file to populate the information for a package of kind Tekton task or pipeline. Usually most of the information needed is already there, so there is no extra work required by maintainers to list their tasks or pipelines 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 manifest file.
- artifacthub.io/alternativeName (string)
Sometimes a package can be identified by two similar names. Some examples would be postgres / postgresql or mongodb / mongo. Users often may type any of the options and expect the same results. When searching for packages, Artifact Hub gives preference to exact matches in names, so sometimes the top results may not be what users would expect. This situation can be improved by providing an alternative name for your package, which will be given the same weight as the package name when indexing. So in cases like the previous examples, it can help ranking them higher in the search results.
Please note that the alternative name must be a substring of the name, or the name must be a substring of the alternative name.
- artifacthub.io/category (string, see example below)
This annotation allows publishers to provide the package’s category. Please use only one category from the following list:
When a category is not provided, Artifact Hub will try to predict one from the package’s keywords by using a machine learning-based model. If you notice that the prediction isn’t correct, we really appreciate that you submit the correct category as it helps us to train and improve the model. In the case that the prediction isn’t correct but your package doesn’t fit well in any of the categories supported, you can use the special value
skip-prediction in the category field to prevent an incorrect classification.
- artifacthub.io/changes (yaml string, see example below)
This annotation is used to provide some details about the changes introduced by a given package version. Artifact Hub can generate and display a ChangeLog based on the entries in the
changes field in all your package 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/license (string)
Use this annotation to indicate the package’s license. It must be a valid SPDX identifier.
- artifacthub.io/links (yaml string, see example below)
This annotation allows including named links, which will be rendered nicely in Artifact Hub. By default, a link pointing to the source code of the package will be automatically added.
Some links names have a special meaning for Artifact Hub:
support: when a link named support is provided, a link to report an issue will be displayed highlighted on the package view.
- artifacthub.io/maintainers (yaml string, see example below)
Use this annotation to list the maintainers of this package. Please note that the
- artifacthub.io/provider (string)
Use this annotation to indicate the name of the organization or user providing this package. This may be useful for repositories where packages are provided by a different entity than the one publishing them in Artifact Hub.
- 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.
