### openstack
192.168.30.60  node1 control1
192.168.30.61  node2 compute1
192.168.30.62  node3 ceph1

# setup passwordless sudo for the openstack user on the deployment node, kolla requirment
sudo su -

```

# Create local ssh config

Generate keypair.

```sh
ssh-keygen -t rsa -N '' -f ~/.ssh/id_rsa -C "" <<< y
```

Push keys to Openstack nodes.

```sh
sshpass -p "Password0" ssh-copy-id -o StrictHostKeyChecking=no openstack@192.168.140.60
```

Create local ssh config, ansible targets `node1` as `control1` using this configuration.

```sh
nano -cw ~/.ssh/config
