Chapter 4. Deploying functions
You can deploy your functions to the cluster by using the kn func tool.
4.1. Deploying a function
You can deploy a function to your cluster as a Knative service by using the kn func deploy command. If the targeted function is already deployed, it is updated with a new container image that is pushed to a container image registry, and the Knative service is updated.
Prerequisites
- The OpenShift Serverless Operator and Knative Serving are installed 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>]
Example output
Function deployed at: http://func.example.com
-
If no
namespaceis specified, the function is deployed in the current namespace. -
The function is deployed from the current directory, unless a
pathis specified. - The Knative service name is derived from the project name, and cannot be changed using this command.
-
If no
Note
You can create a serverless function with a Git repository URL by using Import from Git or Create Serverless Function in the +Add view of the Developer perspective.
