Chapter 4. Deploying functions

Prerequisites

• You have installed the OpenShift Serverless Operator and Knative Serving on the cluster.
• You have installed the Knative (kn) CLI.
• You have created 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 have already created and initialized the function that you want to deploy.

Procedure

• Deploy a function:

  $ kn func deploy [-n <namespace> -p <path> -i <image>]

  You get an output similar to the following example:

  Function deployed at: http://func.example.com

  • If you do not specify a namespace, the command deploys the function in the current namespace.
  • The command deploys the function from the current directory unless you specify a path.
  • The command derives the Knative service name from the project name. You cannot change the service name by using this command.
