Self-managed instances

Self-managed physical instance

Create an instance

In order to create a simple self-managed physical instance not integrated with Puppet you can follow the same steps as for VM creation, i.e.

[lxplus]$ openstack server create --flavor p1.abc123 --image "my-openstack-image" --key-name "my-openstack-key-name" my-physical-instance

Note: The use of the cern-waitdns property is not supported when creating physical instances.

Access to your physical instance

Similarly to virtual machines, the --key-name parameter specified during creation will allow root access to the instance via this key.

Standard CERN Linux and Windows images will equally allow access via LDAP provisioned ssh keys.

Alternatively, you could use an image with your credentials embedded.

As soon as your instance is in ACTIVE state, you can access it using the name you have provided in the previous step. Due to the network infrastructure limitations openstack server show my-physical-instance will not show an IP address associated with your machine, but you can check it in the LanDB portal.

Delete an instance

For deleting an instance you can follow the same steps as for VM deletion, i.e.

[lxplus]$ openstack server delete my-physical-instance

This command will delete your instance from the physical node and erase its hard drives so the machine is ready to be used with a new instance in the future.
