Chapter 2. Installing Camel K


This chapter explains how to install Red Hat Integration - Camel K and OpenShift Serverless on OpenShift, and how to install the required Camel K and OpenShift client tools in your development environment.

2.1. Installing Camel K from the OpenShift OperatorHub

You can install the Red Hat Integration - Camel K Operator on your OpenShift cluster from the OperatorHub. The OperatorHub is available from the OpenShift Container Platform web console and provides an interface for cluster administrators to discover and install Operators. For more details on the OperatorHub, see the OpenShift documentation.

Prerequisites

  • You must have cluster administrator access to an OpenShift 4.6 cluster
Note

You do not need to create a pull secret when installing Camel K from the OpenShift OperatorHub. The Camel K Operator automatically reuses the OpenShift cluster-level authentication to pull the Camel K image from registry.redhat.io.

Procedure

  1. In the OpenShift Container Platform web console, log in using an account with cluster administrator privileges.
  2. Create a new OpenShift project:

    1. In the left navigation menu, click Home > Project > Create Project.
    2. Enter a project name, for example, my-camel-k-project, and click Create.
  3. In the left navigation menu, click Operators > OperatorHub.
  4. In the Filter by keyword text box, enter Camel K to find the Red Hat Integration - Camel K Operator.
  5. Read the information about the Operator, and click Install to display the Operator subscription page.
  6. Select the following subscription settings:

    • Update Channel > techpreview
    • Installation Mode > A specific namespace on the cluster > my-camel-k-project
    • Approval Strategy > Automatic

      Note

      The Installation mode > All namespaces on the cluster and Approval Strategy > Manual settings are also available if required by your environment.

  7. Click Install, and wait a few moments until the Camel K Operator is ready for use.

2.2. Installing OpenShift Serverless from the OperatorHub

You can install the OpenShift Serverless Operator on your OpenShift cluster from the OperatorHub. The OperatorHub is available from the OpenShift Container Platform web console and provides an interface for cluster administrators to discover and install Operators. For more details on the OperatorHub, see the OpenShift documentation.

The OpenShift Serverless Operator supports both Knative Serving and Knative Eventing features. For more details, see Getting started with OpenShift Serverless.

Prerequisites

  • You must have cluster administrator access to an OpenShift 4.6 cluster

Procedure

  1. In the OpenShift Container Platform web console, log in using an account with cluster administrator privileges.
  2. In the left navigation menu, click Operators > OperatorHub.
  3. In the Filter by keyword text box, enter Serverless to find the OpenShift Serverless Operator.
  4. Read the information about the Operator, and click Install to display the Operator subscription page.
  5. Select the default subscription settings:

    • Update Channel > Select the channel that matches your OpenShift version, for example, 4.6
    • Installation Mode > All namespaces on the cluster
    • Approval Strategy > Automatic

      Note

      The Approval Strategy > Manual setting is also available if required by your environment.

  2. Click the OpenShift Help icon help icon in the toolbar, and select Command Line Tools.
  3. Download and extract the oc - OpenShift CLI archive if this tool is not already installed. For more details, see the OpenShift CLI documentation.
  4. Download and extract the kn - OpenShift Serverless CLI archive if this tool is not already installed. For more details, see the OpenShift Serverless CLI documentation.
  5. Download and extract the kamel - Camel K CLI archive to install.
  6. Add the kamel binary file to your system path. For example, on Linux, you can put kamel in /usr/bin.
  7. Log into your OpenShift cluster using the oc client tool, for example:

    $ oc login --token=my-token --server=https://my-cluster.example.com:6443
