Ubuntu

Overview

The Ubuntu node type is used to run Ubuntu VMs as host nodes in a CML lab.

Features

The refplat ISO includes an Ubuntu "cloud" image that can be configured using cloud-init.

Using Ubuntu Nodes in CML

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 for additional cloud-init examples.
