    Ubuntu Cloud Init Platform

    2 GB DRAM, 1 vCPU (can be adjusted)

    ##### Configuration

    The Ubuntu image uses cloud-init YAML for configuration. Please
    ensure that you have a valid cloud-init configuration in the node's
    Edit Config pane in the Workbench. When you drop an Ubuntu node
    on the canvas in the Workbench, a very brief (but complete) skeleton
    for a cloud-init configuration is added to the node.

    The pre-configured default username on the VM image is ubuntu,
    but the initial config for the node overrides the default_user account
    to be cisco. To log into the node as with this default user account,
    ensure that the cloud-init config for the node either specifies a password
    with the top-level password field or provides at least one SSH public key
    with the top-level ssh_authorized_keys field.

    See [the cloud-init documentation](https://cloudinit.readthedocs.io/en/latest/topics/examples.html)
    for additional cloud-init examples.
