+# Kubespray Installer
+
+This script will clone [kubespray](https://github.com/kubernetes-sigs/kubespray) automatically, and deploy production ready Kubernetes cluster by kubespray.
+
+## Install public key to target nodes
+
+```bash
+# ./copy-ssh-keys.sh <set_of_target_nodes>
+./copy-ssh-keys.sh 192.168.0.1 192.168.0.2 192.168.0.3
+
+# Assign customized username if username isn't cord
+REMOTE_SSH_USER=ubuntu ./copy-ssh-keys.sh 192.168.0.1 192.168.0.2 192.168.0.3
+
+# Select the desired public key (default: id_rsa.pub)
+SSH_PUBKEY_PATH=~/.ssh/onoscorddev.pub ./copy-ssh-keys.sh 192.168.0.1 192.168.0.2 192.168.0.3
+```
+
+Then you are able to ssh into the target nodes without password, this is required by Kuberspray script.
+
+## Run the installation script
+
+```bash
+# ./setup -i <inventory_name> <set_of_target_nodes>
+./setup -i pod1 192.168.0.1 192.168.0.2 192.168.0.3
+
+# You can also pipe the output to stdout & file
+./setup -i pod1 192.168.0.1 192.168.0.2 192.168.0.3 | tee /tmp/kubespray-installer.log
+
+# Assign customized username
+REMOTE_SSH_USER=ubuntu ./setup -i pod1 192.168.0.1 192.168.0.2 192.168.0.3
