Kolla Kubernetes Setup Guide¶
The most well tested setup guide for Kuberentes is the ::doc:: minikube-quickstart. It will walk through the entire setup including getting Kubernetes and OpenStack deployed. This guide is an alternative method for starting Kubernetes.
Single-node Kubernetes setup¶
- DNS services
- dnsmasq
- kube-dns
- healthz
- Hypercube service
- kubernetes-dashboard
- kube-addon-manager
- controller-manager
- apiserver
- scheduler
- kube-proxy
- kubelet

Kubernetes manipulates firewall rules so we want it to be the only service on the host doing that or some of the containers will fail. Disable the firewall on your host:
# CentOS
systemctl stop firewalld
systemctl disable firewalld
Execute the following commands to create an all-in-one Kubernetes setup:
git clone https://github.com/kubernetes/kube-deploy
./kube-deploy/docker-multinode/master.sh
The setup-kubectl.sh script will pull the latest kubectl from git:
git clone https://github.com/openstack/kolla-kubernetes
cd kolla-kubernetes
./tools/setup-kubectl.sh
Try it out:
kubectl get services --all-namespaces
To confirm that DNS services are working, you can start a busybox job which will
check if kubernetes is resolvable from inside of it. If the job completes,
then DNS is up and running.
kubectl create -f tools/test-dns.yml
kubectl get jobs
