1. Create VM

Create VM

Create the VM(s) where you are going to install SDN-C cluster on Kubernetes with the following:

Do the following steps to enable password logging for unbuntu user in VM:

#	Purpose	Example
1	create password for ubuntu user	ubuntu@sdnc-k8s:~$ sudo passwd ubuntu sudo: unable to resolve host sdnc-k8s Enter new UNIX password: <enter password> Retype new UNIX password: <repeat entering the same password> passwd: password updated successfully
2	(optional) fix "unable to resolve host" issue	ubuntu@sdnc-k8s:~$ sudo vi /etc/hosts sudo: unable to resolve host sdnc-k8s add the host name to the localhost in the following format: <IP address> <hostname> localhost
3	config ssh "*PasswordAuthentication" to yes*	ubuntu@sdnc-k8s:~$ sudo vi /etc/ssh/sshd_config find PasswordAuthentication and set its value to yes, so that the line looks like # Change to no to disable tunnelled clear text passwords PasswordAuthentication yes
4	restart sshd to enable the new config	ubuntu@sdnc-k8s:~$ systemctl restart sshd passwd ==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units === Authentication is required to restart 'ssh.service'. Authenticating as: Ubuntu (ubuntu) Password: ==== AUTHENTICATION COMPLETE === ==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units === Authentication is required to restart 'passwd.service'. Authenticating as: Ubuntu (ubuntu) Password: ==== AUTHENTICATION COMPLETE === Failed to restart passwd.service: Unit passwd.service not found.

As part of investigation of ODL clustering in kubernetes network, we turned off firewall by using the following commands:

sudo ufw disable

sudo iptables -I INPUT -j ACCEPT

These commands disables the firewall and allow all incoming HTTP connections. It's not recommneded to do this in the real production envrionment.

We are using them as an easy alternative as we are still in progress of investigating in the development environment under the kubernetes network.
