kn-api-server-source

A helm chart that installs knative-eventing and deploys an ApiServerSource follwing the Creating an ApiServerSource Object guide from knative-eventing. The ApiServerSource is deployed in the api-server-source namespace by default. By default the ApiServerSource is listening for events in the test namespace.

To deploy and have ApiServerSource send cloud events to a Channel use the channel branch of this repo.

To deploy and have ApiServerSource send cloud events to a Broker use the broker branch of this repo.

Requirements

• Helm must be installed. Installation instructions for helm can be found here
• Follow the instructions for verifying image signatures for knative-eventing here
• On linux make sure that you have kvm virtualization installed and running. On fedora/rhel run

sudo dnf install @virtualization

sudo systemctl enable --now libvirtd

sudo usermod -aG libvirt $USER

newgrp libvirt

• Be logged into a kubernetes cluster. If you don't have a cluster, installation instructions for minikube can be found here
• If using minikube on linux, docker or podman must be installed. On fedora/rhel run

sudo dnf install (podman|docker)

• If podman installed add the following alias to your .bashrc

alias docker=podman

• If docker installed run the following commands

sudo usermod -aG docker $usermod

newgrp docker

• Start minikube

minikube start --driver=kvm2

• Apply knative CRDs (Helm doesn't do a good job managing CRDs)

kubectl apply -f https://github.com/knative/eventing/releases/download/knative-v1.13.3/eventing-crds.yaml

kubectl apply -f https://github.com/knative/eventing/releases/download/knative-v1.13.3/eventing-core.yaml

kubectl apply -f https://github.com/knative/eventing/releases/download/knative-v1.13.3/in-memory-channel.yaml

kubectl apply -f https://github.com/knative/eventing/releases/download/knative-v1.13.3/mt-channel-broker.yaml

Use the Chart

To deploy

helm install -g .

To see deployments from helm

helm ls

To remove the deployment

helm ls -q | awk '{print $1}' | xargs -I {} helm uninstall {}

This command assumes that the install of this chart is the first one listed by helm ls. If that is not the case change awk command to

awk '{print $<position number>}'
