Quick and Dirty Single Node Kubernetes

README.md

Quick and Dirty Single Node Kubernetes Setup.

Preq-reqs:

• You need a node
• Your node's OS should be Linux
• It should be a good Linux distro (Ubuntu 15.10)
• Not a bad one
• It should have Docker running
• It should be disposable
• It shouldn't have been previously traumatized

Create a working directory.

mkdir ~/kube-single

Grab releases of etcd and kubernetes

curl -L -O https://github.com/coreos/etcd/releases/download/v2.2.5/etcd-v2.2.5-linux-amd64.tar.gz
curl -L -O https://github.com/kubernetes/kubernetes/releases/download/v1.2.0/kubernetes.tar.gz

Decompress all the things.

tar -zxvf etcd-v2.2.5-linux-amd64.tar.gz
tar -zxvf kubernetes.tar.gz
tar -zxvf kubernetes/server/kubernetes-server-linux-amd64.tar.gz 

Copy these binaries you downloaded from the Internet into your path.

mkdir -p /opt/bin
cd ~/kube-single
cp etcd-v2.2.5-linux-amd64/etcd /opt/bin/
cp kubernetes/server/bin/!(*.*) /opt/bin
cp kubernetes/platforms/linux/amd64/kubectl /opt/bin
export PATH=$PATH:/opt/bin

What are you doing with stuff in your path that isn't executable?

chmod +x /opt/bin/*

Start all the things.

etcd &
kube-apiserver --service-cluster-ip-range=10.100.0.0/16 --etcd-servers=http://127.0.0.1:2379 &
kube-controller-manager --master=http://127.0.0.1:8080 &
kube-scheduler &
kube-proxy &
kubelet --api-servers=http://127.0.0.1:8080 &

That's a lot of spam. Open a new terminal and type this.

kubectl get all

Awwww Yissss.

kubectl run -i --tty busybox --image=busybox --restart=Never
