I'm going through OpenStack (tutorial)

In the subsection "Set Up Ssh" it says "Set up the stack user on each node with an ssh key for access". Do I need to spawn up the worker nodes (VMs) myself rather than using the cluster controller to spin up the worker nodes?

If I need to spin up the workers nodes myself, I suppose I need to give them the following IPs (for example):

auto eth0 iface eth0 inet static


auto eth0 iface eth0 inet static

Furthermore, what is the role of the gateway?

It's like a jump node or something?

Yes, you need to create the worker nodes and configure them as suggested at

Gateway is the router in your network.

If you don't know the meaning of the gateway clause, I suggest you study networking in general and Linux networking in particular before you set up an OpenStack cluster. Without networking skills, you will have plenty of problems. By the way, the network setup in the instructions only works for Ubuntu 16 and earlier. Ubuntu 18 and later uses a different configuration tool named netplan.
