Step 1. Setup vagrant
Step 2: Update /etc/hosts on all the nodes
vagrant@amaster:~$ sudo vi /etc/hosts
100.0.0.1 amaster.jhooq.com amaster
100.0.0.2 kmaster.jhooq.com kmaster
100.0.0.3 kworker.jhooq.com kworker
Step 3: Generate SSH key for ansible
vagrant@amaster:~$ ssh-keygen -t rsa
Step 4: Copy SSH key to other nodes
vagrant@amaster:~$ ssh-copy-id 100.0.0.2
vagrant@amaster:~$ ssh-copy-id 100.0.0.3
Step 5: Install python3-pip
vagrant@amaster:~$ sudo apt install python3-pip
Step 6: Clone the kubespray git repo
vagrant@amaster:~$ git clone https://github.com/kubernetes-sigs/kubespray.git https://github.com/kubernetes-sigs/kubespray.git
Step 7: Install kubespray package
vagrant@amaster:~/kubespray$ sudo pip3 install -r requirements.txt
Step 8: Copy inventory file to current users
vagrant@amaster:~/kubespray$ cp -rfp inventory/sample inventory/mycluster
Step 9: Prepare host.yml for kubespray
vagrant@amaster:~/kubespray$ declare -a IPS=(100.0.0.2 100.0.0.3)
vagrant@amaster:~/kubespray$ CONFIG_FILE=inventory/mycluster/hosts.yml python3 contrib/inventory_builder/inventory.py ${IPS[@]}
Step 10: Run the ansible-playbook on ansible node
ansible-playbook -i inventory/mycluster/hosts.yml --become --become-user=root cluster.yml
Step 11: Install kubectl on kubernetes master
vagrant@node1:~$ curl -LO https://storage.googleapis.com/kubernetes-release/release/`curl https://storage.googleapis.com/kubernetes-release/release/`c... -s https://storage.googleapis.com/kubernetes-release/release/stable.txt`/bin/linux/amd64/kubectl https://storage.googleapis.com/kubernetes-release/release/st...
vagrant@node1:~$ sudo cp /etc/kubernetes/admin.conf /home/vagrant/config
vagrant@node1:~$ mkdir .kube
vagrant@node1:~$ mv config .kube/
vagrant@node1:~$ sudo chown $(id -u):$(id -g ) $HOME/.kube/config
Step 12: Verify the kubernetes nodes
vagrant@node1:~$ kubectl get nodes
NAME STATUS ROLES AGE VERSION
