Here we have another example of deploying a simple virtual machine with a floating ip address. The prerequisites for this stack are an existing router that is connected to the external network as can be seen below:
And the ID of the external network that the router has been connected to:
Amend the input parameters of the stack to align with your environment and then it’s just business as usual – load and submit the stack.
