Kubernetes Linux Distribution Packages Builder

Kubernetes is in pre-production beta!

While the concepts and architecture in Kubernetes represent years of experience designing and building large scale cluster manager at Google, the Kubernetes project is still under heavy development. Expect bugs, design and API changes as we bring it to a stable, production product this year.

Quick Install (RedHat 7, CentOS 7, Debian 7, Ubuntu 14.x)

• Kubernetes master: curl -sSL https://get.kismatic.com/kubernetes/master.sh | sudo sh

• Kubernetes nodes: curl -sSL https://get.kismatic.com/kubernetes/node.sh | sudo sh

• Requirements:

  • Install etcd (on master or a separate etcd cluster)
  • Install docker (ubuntu/debian only)

##Configuration and Manual Setup

System.d and RedHat 7 / CentOS 7 Configuration

rpm -Uvh https://repos.kismatic.com/el/7/x86_64/kismatic-repo-el-7-1.x86_64.rpm Master: sudo yum install kubernetes-master Nodes: sudo yum kubernetes-node

Configure Kubernetes Master

Configure Kubernetes Master To configure services, edit configuration files in /etc/kubernetes/master or /etc/kubernetes/node To override services, copy /lib/systemd/system to /etc/systemd/system to override. This allows you to customize local services without worrying about losing changes as the result of a package upgrade.

Add minions to kube-controller-manager.conf When running on bare metal (or without a cloud config), set the --machines= flag to your static IPs to bootstrap nodes. Alternatively you could leave it blank, and manually register each node with kubectl create node -f <file> after it is up. https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/node.md

Start services sudo systemctl start kube-apiserver sudo systemctl start kube-scheduler sudo systemctl start kube-controller-manager sudo systemctl start kubelet

test with curl -L http://<master ip>:8080/version

Configure Kubernetes Node

Set --master=<master ip> for a node in /etc/kubernetes/node/kube-proxy.conf and --master=<master ip> in /etc/kubernetes/node/kubelet.conf

sudo systemctl start kube-proxy sudo systemctl start kubelet

Check services are running systemctl list-units -t service --all

Init.d and Debian 7 (wheezy)/ Ubuntu 14.x (trusty) Configuration

Install docker on Ubuntu or Debian and etcd

Configure Kubernetes

To configure services, edit the file with the same name in /etc/default

Master kube-controller-manager: when running on bare metal (or without a cloud config), set the --machines= flag to your static IPs to bootstrap nodes. Alternatively you could leave it blank, and manually register each node with kubectl create node -f <file> after it is up. https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/node.md

sudo service kube-apiserver start
sudo service kube-scheduler start
sudo service kube-controller-manager start
sudo service kubelet start

Configure Node Set the --master for a node in /etc/default/kube-proxy and --api-servers in /etc/default/kubelet

sudo service kube-proxy start
sudo service kubelet start
