[ahmed@icp:~]$ cd /opt/ibm-cloud-private-ce-2.1.0.2



[ahmed@icp:/opt/ibm-cloud-private-ce-2.1.0.2]$ sudo docker run  -e LICENSE=accept -v "$(pwd)":/data ibmcom/icp-inception:2.1.0.2 cp -r cluster /data
Create RSA key:
[root@icp:~]# ssh-keygen -b 4096 -f ~/.ssh/id_rsa -N  ""


 
[root@icp:~]# cat ~/.ssh/id_rsa.pub | sudo tee -a ~/.ssh/authorized_keys


 
[root@icp:/opt/ibm-cloud-private-ce-2.1.0.2]# cp /root/.ssh/id_rsa ./cluster/ssh_key
Add ansible hosts:
