Assigning a floating IP to an instance

Your freshly made machine lives on your own private network, created by you, and is thus currently unreachable from the rest of the world. To enable outside access to the machine you would need to assign a floating IP address to it.

If this is the first time you use a floating IP, there are probably no IP allocated to your project. To allocate an IP to your project you could use the following command:

Code Block
loginansatt01:~$ openstack floating ip create ntnu-internal

To assign a floating IP to a virtual machine, you would use the following command:

Code Block
loginansatt01:~$ openstack server add floating ip MySecondServer 10.212.136.21

At this point you should be able to ping the server:

Code Block
loginansatt01:~$ ping 10.212.136.21
