Atmosphere configures an SSH keypair which allows you to login to the Amphorae for debugging purposes. The octavia-worker containers are fully configured to allow you to SSH to the Amphorae.
If you have an Amphora running with the IP address 172.24.0.148, you can login to it by simply executing the following:
kubectl -n openstack exec -it deploy/octavia-worker -- ssh 172.24.0.148
