Important

Developers are highly recommended to use the OpenShift Toolkit extension for Knative Serverless Function workflow to streamline their development process and ensure a seamless experience. All the latest features of Knative Serverless will be maintained in the OpenShift Toolkit extension, supported by Red Hat.

Knative & Serverless Functions for Visual Studio Code

Knative is an Open-Source Enterprise-level solution to build Serverless and Event-Driven Applications. Thus running Serverless Containers in Kubernetes environments.

This extension for Knative provides the app developer with the tools and experience needed when working with Knative & Serverless Functions on a Kubernetes cluster. Using this extension, developers can develop and deploy functions in a serverless way through guided IDE workflow.

Requirements

• Knative extension uses kn cli 1.13.0 and func cli 1.13.0. The extension will offer to download and install the dependencies if needed.

• YAML is validated using the VSCode-YAML extension

• Users can log in to the Kubernetes cluster using VSCode Kubernetes extension.

  NOTE: You will need to have the kubeconfig for the cluster that you are accessing stored locally.

Extension Settings

This extension contributes two views (Knative and Functions) and the following settings:

Functions

• function.explorer.create: Create a new Knative Function in the current namespace
• function.explorer.refresh: Refresh the Functions tree view
• function.explorer.repository: Manage installed template repositories. Once added, a template from the repository can be used when creating a new function.

Function Sessions

• This view is used to showcase Active commands for a specified function. This includes Build, Deploy, and Run sessions. Once the command is executed for a given function, the node is displayed in the Sessions View. Users can also Stop the executing action. The logs can be seen in the Output Channel.
