kpack-demo

This is a script to install kpack on an existing K8's cluster. It's meant to demo the product, so there are some things assumed. Like,

• You already have a healthy K8's cluster, and have loaded its context in your profile's config file.
• The image repository of choice is Docker Hub.
• You have a Docker Hub account
• When installing the needed ClusterBuilder the cloudfoundry/cnb:bionic is used.
• A generic docker-service-account is created for use throughout the cluster. As opposed to a service-account specific to an app.

Getting Started

1. List your installed cluster contexts.

   $ kubectl config get-contexts

2. Using the name retrieved from above output, set your context for kubectl interactions.

   $ kubectl config use-context <CONTEXT_NAME>

3. Head over to the releases page in the kpack repo to download the latest yaml asset. (The install script will ask for its location)

4. Clone this repo.

   $ git clone https://github.com/ddieruf/kpack-demo.git; cd "kpack-demo"

5. Provide credentials for interacting with Docker Hub in the Install-kpack/kpack-assets.yaml file.

6. Run the install script to get everything going. Pass in the location of the kpack manifest downloaded earlier.

   $ ./Install-kpack/install-kpack.sh ./release-XXX.yaml

7. If the script was able to run successfully, it should exit with no error messages and a final "success" message.

8. You are ready to use kpack with an application. Have a look at the preconfigured .NET Core project.

Extra Credit

See the namespace created for kpack things:

kubectl describe namespace "kpack"

List the installed ClusterBuilder details, along with what buildpacks were included:

kubectl describe clusterbuilder "cloud-foundry"

List the pods included in the kpack namespace:

kubectl get pods --namespace "kpack"
