2.2. Creating a function in the web console

Prerequisites

• Before you can create a function by using the web console, a cluster administrator must complete the following steps:

  • Install the OpenShift Serverless Operator and Knative Serving on the cluster.
  • Install the OpenShift Pipelines Operator on the cluster.

  • Create the following pipeline tasks so that they are available for all namespaces on the cluster:

    func-s2i and func-deploy tasks

    $ kn func tkn-tasks | oc apply -f -

    Node.js function

    $ oc apply -f https://raw.githubusercontent.com/openshift-knative/kn-plugin-func/serverless-1.34/pkg/pipelines/resources/tekton/pipeline/dev-console/0.1/nodejs-pipeline.yaml

• You must log into the OpenShift Container Platform web console.
• You must create a project or have access to a project with the appropriate roles and permissions to create applications and other workloads in OpenShift Container Platform.
• You must create or have access to a Git repository that contains the code for your function. The repository must contain a func.yaml file and use the s2i build strategy.

Verification

• After you have created a function, you can view it in the Topology view.
