- rahulwagh17 6y agoStep 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 node1 Ready master 13m v1.18.2 node2 Ready master 13m v1.18.2
