## AI overview

Ubuntu 18.04 LTS images are available in the cPouta and ePouta cloud environments. The article explains that the images use Canonical's unmodified image, the default SSH user is ubuntu, and users can upload other Ubuntu cloud images or configure users with cloud-init and the OpenStack CLI.

## Source excerpt

Hello Ubuntu fan boys and girls! An image containing latest LTS Ubuntu release (18.04 Bionic Beaver) is now available in c and ePouta! This time we opted to use the image provided by Canonical without any modifications. This means the user used to ssh in is now "ubuntu" instead of "cloud-user". In any case, trying to ssh in as root will tell you which user to ssh in as In case you want to try even newer versions of Ubuntu, say the "in-between" releases like 18.10 Cosmic Cuttlefish - head over to http://cloud-images.ubuntu.com/ , select the release and fetch the "cloudimg-amd64.img" - for example "cosmic-server-cloudimg-amd64.img" - which is a QCOW2 image. This you can then upload as an image in your c/ePouta project. Our user guide has some pictures and instructions how to work with and upload new images: https://research.csc.fi/pouta-adding-images To add your ssh key under a new "cloud-user" (in case you don't want to use ubuntu user) you can do something like below. First create a file that has the cloud-init user data. Then use that file as input to the openstack CLI tool. $ cat cloud-init.cfg #cloud-config users: - default: - default_user: name: cloud-user gecos: Cloud User sudo: ["ALL=(ALL) NOPASSWD:ALL"] ssh_authorized_keys: - ssh-ed25519 AAAAMYKEYQ user@email.example.org And then the openstack CLI command : $ openstack server create ubuntu1804 --flavor standard.small --image Ubuntu-18.04 --key mykey --security-group default --security-group ssh-group --user-data cloud-init.cfg It is if course possible to use horizon to supply the user data as well. p.s. Yes, ed25519 keys works this way! The web interface openstack horizon still does not support them yet.
