Openwhisk Catalog

Build Status License

This openwhisk-catalog maintains the package catalogs of openwhisk. In OpenWhisk, the catalog of packages gives you an easy way to enhance your app with useful capabilities, and to access external services in the ecosystem. Examples of external services that are OpenWhisk-enabled include IBM Watson API, the Weather Company, Slack, and GitHub.system packages and sample packages.

The catalog is available as packages in the /whisk.system namespace. See Browsing packages for information about how to browse the catalog by using the command line tool.

How to install openWhisk-catalog


  • openwhisk is installed.
  • Environment variable OPENWHISK_HOME is configured as the path to openwhisk source code directory.

Apache OpenWhisk Catalog is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

You can’t perform that action at this time.
