Kubernetes Offline Automated Installation

While working on kubernetes and docker there are some scenarios where we need to deploy Kubernetes cluster setup in on-premise without internet.

Here I have given the solution how to achieve this,

Requirements:

OS : Centos/RHEL- 7.4/7.5

Total servers : 3 (Kubernetes Master 1, Kubernetes node -2)

Suggested Resources : 2Core,4GB RAM,25GB HDD each server.

Deployments:

1.Kubernetes

2.Kubernetes Nginx Ingress

3.Docker

4.Docker registry

Kubernetes installing version 1.13.4.

Installation:

Download this below git repository and below links images from Internet machine,

#git clone https://github.com/DevOpsArts/kubernetes-automated-offline-installation.git

K8sMaster image:

https://drive.google.com/file/d/1z-SSA4ZBxqfRtY-Gv38lppgqo3UvtyUr/view?usp=sharing

K8sNode image :

https://drive.google.com/file/d/1OYvR9A1oNjbzAuU-JE-HHfAbzi9dUz-k/view?usp=sharing

And keep the downloaded both images in, app/k8simages directory.

Master server :

1.Run setup.sh then reboot the server.

2.After rebooted, run install.sh to do the installation.

Node Servers :

1.Run setup.sh then reboot the server.

2.After rebooted, run install.sh to do the installation.

Thats it, Your kubernetes cluster setup will run and works fine.
