Run local kubernetes cluster

VirtualBox, Vagrant should be installed. It is simple.


Install kubectl (client to work with kubernetes cluster)



-- get current stable version (v1.14.1)
$ echo $(curl -sS https://storage.googleapis.com/kubernetes-release/release/stable.txt)


-- install
$ curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl && chmod +x kubectl && sudo mv kubectl /usr/local/bin/


Prepare hosts file


$ sudo vi /etc/hosts

192.168.0.10 master.k8s master
192.168.0.11 node1.k8s node1
192.168.0.12 node2.k8s node2


Run local kubernetes cluster

$ vagrant plugin install vagrant-hostmanager



$ mkdir ~/vagrant-kubernetes && cd ~/vagrant-kubernetes

# git clone https://bitbucket.org/sysadm-ru/kubernetes .

$ cd vagrant-provisioning/

$ vagrant up


Copy special config file on host to manage cluster remotely


$ mkdir -p ~/.kube/config



// root password: kubeadmin
$ scp root@master:/etc/kubernetes/admin.conf ~/.kube/config



$ kubectl version --short
Client Version: v1.14.1
Server Version: v1.14.1



$ kubectl get nodes
