README

catalogd

Catalogd is a Kubernetes extension that unpacks file-based catalog (FBC) content for on-cluster clients. Currently, catalogd unpacks FBC content that is packaged and distributed as container images. The catalogd road map includes plans for unpacking other content sources, such as Git repositories and OCI artifacts. For more information, see the catalogd issues page.

Catalogd helps customers discover installable content by hosting catalog metadata for Kubernetes extensions, such as Operators and controllers. For more information on the Operator Lifecycle Manager (OLM) v1 suite of microservices, see the documentation for the Operator Controller.

Quickstart DEMO

Quickstart Steps

NOTE: Procedure steps marked with an asterisk (*) are likely to change with future API updates.

1. To install catalogd, navigate to the releases page, and follow the install instructions included in the release you want to install.

2. Create a Catalog object that points to the OperatorHub Community catalog by running the following command:

   $ kubectl apply -f - << EOF
   apiVersion: catalogd.operatorframework.io/v1alpha1
   kind: Catalog
   metadata:
     name: operatorhubio
   spec:
     source:
       type: image
       image:
         ref: quay.io/operatorhubio/catalog:latest
   EOF
   

3. Verify the Catalog object was created successfully by running the following command:

   $ kubectl describe catalog/operatorhubio

4. Port forward the catalogd-catalogserver service in the catalogd-system namespace:

   $ kubectl -n catalogd-system port-forward svc/catalogd-catalogserver 8080:80
   

5. Run the following command to get a list of packages:

   $ curl http://localhost:8080/catalogs/operatorhubio/all.json | jq -s '.[] | select(.schema == "olm.package") | .name'
   

   Example output

     % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                   Dload  Upload   Total   Spent    Left  Speed

Contributing

Thanks for your interest in contributing to catalogd!

catalogd is in the very early stages of development and a more in depth contributing guide will come in the near future.

In the mean time, it is assumed you know how to make contributions to open source projects in general and this guide will only focus on how to manually test your changes (no automated testing yet).

If you have any questions, feel free to reach out to us on the Kubernetes Slack channel #olm-dev or create an issue

Testing Local Changes

Prerequisites

• Install kind

Test it out

make run

This will build a local container image for the catalogd controller, create a new KIND cluster and then deploy onto that cluster.
