Knative Camel

This repository contains the OLM manifests for the Knative Camel add-on.

User instructions

Knative Camel can be installed directly from Operator Hub and it has the following prerequisites:

  • Knative Eventing
  • Knative Serving
  • Camel K

NOTE: Knative Camel 0.10.0 is compatible with Camel K 1.0.0-M4, which cannot be installed from Operator Hub.

The Camel K client can be downloaded from the 1.0.0-M4 release page and installed following the instructions in the github repository.

Camel K 1.0.0-M4 should be installed in "All Namespaces" mode in order to use it in Camel Sources.

For example, to use Knative Camel in an example namespace, follow these steps:

Installing Camel K in an example namespace

  1. Create the example namespace by navigating to Home > Projects in the Web Console. Click Create Project and a dialog box will appear.

  2. Enter example in the name field and click Create. The example namespace is now created. Alternatively you can use oc or kubectl to create.

  3. Navigate to the Developer Catalog of the namespace to create a Camel K Integration Platform resource.

  4. Once all prerequisites are installed, you can install the Knative Camel add-on.

  5. Knative Camel can be installed in All Namespaces from the Operator Hub console.

  6. After the installation is complete, in the Developer Catalog section a new Camel Source object will be listed.

  7. The example Camel Source resource aim to push events into a Knative Eventing channel, so follow the Knative Eventing documentation to create a channel named camel-test.

  8. Once the camel-test channel is created, you can create the example Camel Source.

  9. After the initialization is done, it will run in the cluster.

Development instructions

This repo contains only the manifests for installing Knative Camel on a Kubernetes cluster supporting OLM.

To test the CSV, you can push the manifest to quay.io and create a operator source to track it.

To push the manifest to quay, use the commands:

export QUAY_USERNAME=your-user
export QUAY_PASSWORD=your-password
./push-to-quay.sh

By default applications in Quay have private scope. You need to go to the quay user interface, from the Applications tab, select knative-camel, and change the visibility to public.

Edit the operatorsource.yaml file and set your username in the registryNamespace field (it is set to nferraro by default).

Run:

oc create -f operatorsource.yaml

The operator will be displayed in the OpenShift marketplace.

NOTE: If you want to republish the operator, you need to first delete the application from quay.
