With manually installed Kubernetes on CoreOS, how does one install and use the Kubernetes addon manager?
I've found references to the addon manager being the current standard way of installing Kubernetes addons, but I can't find any authoritative documentation on it. Hoping someone can help me out here.

Addon Manager: A kubernetes controller in the hub cluster that applies manifests to the managed clusters via the ManifestWork api. In addition to resource dispatching, the manager can optionally manage the lifecycle of CSRs for the addon agents or even the RBAC permission bond to the CSRs' requesting identity.
The addon manager is deployed as a normal pod or a deployment, with a simple kubectl apply -f.
The yaml looks something like this, look at the specific version that you need:
apiVersion: v1
kind: Pod
metadata:
name: kube-addon-manager
namespace: kube-system
labels:
component: kube-addon-manager
spec:
hostNetwork: true
containers:
- name: kube-addon-manager
# When updating version also bump it in:
# - cluster/images/hyperkube/static-pods/addon-manager-singlenode.json
# - cluster/images/hyperkube/static-pods/addon-manager-multinode.json
# - test/kubemark/resources/manifests/kube-addon-manager.yaml
image: gcr.io/google-containers/kube-addon-manager:v6.4-beta.1
command:
- /bin/bash
- -c
- /opt/kube-addons.sh 1>>/var/log/kube-addon-manager.log 2>&1

requests:
cpu: 5m
memory: 50Mi
volumeMounts:
- mountPath: /etc/kubernetes/
name: addons
readOnly: true
- mountPath: /var/log
name: varlog
readOnly: false
volumes:
- hostPath:
path: /etc/kubernetes/
name: addons
- hostPath:
path: /var/log
name: varlog
The addon manager observes the specific yaml files under /etc/kubernetes/addons/, put any addon you like here to install it.
