Deploy

In order to deploy into a Knative cluster, you must first create images and publish them into a repository. We will be using Docker for that purpose.

The ./hack/build.sh --docker-images and ./hack/build.sh --docker-push will respectively create Docker images and push them in your Docker Hub account for you. Or use --docker to both build and push the images at once.

You need to make sure the docker executable is visible to your shell and that the environment variable DOCKER_USERNAME is set to your Docker Hub user ID.

./hack/build.sh --docker-images
🚧 🐳 build images
   🚧 🐳 twitter-fn
Sending build context to Docker daemon  55.42MB

   🚧 🐳 watson-fn
...
Successfully tagged drmax/watson-fn:latest
   🚧 🐳 summary-fn
...
Successfully tagged drmax/summary-fn:latest

And when publishing the images.

./hack/build.sh --docker-push
🐳 push images
   🐳 twitter-fn
The push refers to repository [docker.io/drmax/twitter-fn]
...
   🐳 watson-fn
The push refers to repository [docker.io/drmax/watson-fn]
...
   🐳 summary-fn
...

Your images should not be avaible at:

  1. docker.io/${DOCKER_USERNAME}/twitter-fn
  2. docker.io/${DOCKER_USERNAME}/watson-fn
  3. docker.io/${DOCKER_USERNAME}/summary-fn

You can use these images to deploy the functions into your Knative cluster with the kn CLI.

You are welcome to use my images at:

  1. docker.io/drmax/twitter-fn:latest
  2. docker.io/drmax/watson-fn:latest
  3. docker.io/drmax/summary-fn:latest
