Deploying a Cluster

Download kubectl

kubectl is a command-line tool for managing everything about your Kubernetes cluster.

The following set of commands can be used to install kubectl on your machine. You may need to change the version number below:

export K8S_VERSION=1.2.0
mkdir ~/bin
curl -L "https://storage.googleapis.com/kubernetes-release/release/${K8S_VERSION}/bin/linux/amd64/kubectl" > .
export PATH=$PATH:`pwd`
chmod +x ~/bin/*

Single-Node (Local Development) Cluster

Provided in the source code for NDS Labs is a script called kube-up.sh which will launch a local kubernetes cluster on your machine.

It will also download kubectl for you, as described above, and place it into the ~/bin/ folder.

#!/bin/sh
docker run \
    --volume=/:/rootfs:ro \
    --volume=/sys:/sys:ro \
    --volume=/var/lib/docker/:/var/lib/docker:rw \
    --volume=/var/lib/kubelet/:/var/lib/kubelet:rw \
    --volume=/var/run:/var/run:rw \
    --volume=`pwd`/manifests/etcd.json:/etc/kubernetes/manifests/etcd.json \
    --net=host \
    --pid=host \
    --privileged=true \
    -d \
    gcr.io/google_containers/hyperkube-amd64:v{K8S_VERSION} \
    /hyperkube kubelet \
        --containerized \
        --hostname-override="127.0.0.1" \
        --address="0.0.0.0" \
        --api-servers=http://localhost:8080 \
        --config=/etc/kubernetes/manifests \
        --allow-privileged=true --v=2
mkdir -p ~/bin
if [ ! -e ~/bin/kubectl ]; then
	curl http://storage.googleapis.com/kubernetes-release/release/${K8S_VERSION}/bin/linux/amd64/kubectl -o ~/bin/kubectl
	chmod +x ~/bin/kubectl
fi

NOTE: The first time you start your cluster, Kubernetes will tell docker to download several images.

This happens in the background and can take several minutes, so please be patient.
