Deleting the Application and Virtual Machine

We can delete our application once we no longer need it.

Command Line Interface

First, we need to connect to the virtual machine, stop the Genie application and Nginx, and then unmount the persistent storage volume.

sudo umount /dev/vdb

Then, let's disconnect from the virtual machine. Now, we can detach the persistent storage from the virtual machine.

openstack server remove volume $SERVER_NAME $VOLUME_NAME

Next, we can remove the virtual machine.

openstack server delete $SERVER_NAME

Finally, we can remove the floating IP.

openstack floating ip delete $FLOATING_IP

Additionally, we can remove the persistent storage. Removing the persistent storage will destroy the database and logs.

openstack volume delete $VOLUME_NAME

Now, we have deleted the application and virtual machine.
