- Project Management Network	
A network needs to be created to store instances deployed by CloudShell Apps:

1) Assign a subnet to the network.
2) Make sure the network is not external. Every instance will have a network port on the management network.
3) Set the network's shared flag to True. The network will be shared by instances.
4) Make sure QualiX Server has a floating IP and is part of this network so that it can be accessed from external networks.

1) Set a Enviroment variable
> Download RC file from the Dashboard, And Run a [project_name]-openrc.sh

2) Permission denied on the Root privilege
 bash -x demo-openrc.sh //this command is not working

3) Missing value auth-url required for auth plugin password

=> https://superuser.com/questions/227505/what-is-the-difference-between-nat-bridged-host-only-networking
   Host-Only: The VM will be assigned one IP, but it's only accessible by the box VM is running on. No other computers can access it.
   NAT: Just like your home network with a wireless router, the VM will be assigned in a separate subnet, like 192.168.6.1 is your host computer, and VM is 192.168.6.3, then your VM can access outside network like your host, but no outside access to your VM directly, it's protected.
   Bridged: Your VM will be in the same network as your host, if your host IP is 172.16.120.45 then your VM will be like 172.16.120.50. It can be accessed by all computers in your host network.

=> https://serverfault.com/questions/490043/differences-between-bridged-and-nat-networking
   Bridged connections are just that, essentially a virtual switch is connected between the VM and your physical network connection.
   NAT'd connections are also just that, instead of a switch a NAT router is between the VM and your physical network connection.  

=> The Internet Assigned Numbers Authority (IANA) has reserved thefollowing three blocks of the IP address space for private internets:

10.0.0.0 - 10.255.255.255 (10/8 prefix)
172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
192.168.0.0 - 192.168.255.255 (192.168/16 prefix)
