It’s now time to show case what it takes to run an existing OpenWhisk action on Knative. Matt Rutkowski and I are very excited to share our process of building and serving OpenWhisk actions on Knative here. We started prototyping OpenWhisk NodeJS Runtime with a hello world action. Later, extended the runtime to handle more complex use cases such as: It’s a six step process, first three steps are one time deployment per Knative installation. The whole build and serve process is based on Knative Source-to-URL workflow. Knative needs access to your container registry in order to push locally built container image. I am using Docker Hub here but you can use any registry of your choice by changing the registry name under annotation.
