Node setup¶

Nodes are typically configured during installation from the customized openSUSE Leap or Debian 10 ISOs. See Creating bootable USB disks from ISO images for more information on using these custom ISOs. The node setup page offers links to customized ISOs and offers options for generating the customized ISOs.

Changing the settings does not change the values on already-installed nodes; it only changes the initial settings for nodes that are installed with ISO files downloaded after the settings are changed.

After changing any of these values, you need to download a new version of the ISO.

Root password¶

The password of the node’s root user account.

Timezone¶

The node’s timezone.

DNS servers¶

Specify one, two, or three DNS servers used during the provisioning process.

Network interface names¶

Specify which interface naming scheme will be used for nodes provisioned with this ISO.

There are 2 options:

Predictable network interface naming¶

Generally used as the naming scheme for interfaces on modern Linux distributions, these interface names are called predictable as they are based off of hardware information such as which PCI device they are attached to.

These interface names tend to look like ens3, enp37s0, or enp42s0f1.

Legacy network interface naming¶

Sometimes referred to as “persistent interface names”, these names are determined when the network card is first detected and the network interfaces will be renamed to be consistent between boots of the system.

These interface names tend to look like eth0, eth1, or eth2

These interfaces can start to have issues when many interfaces are present, especially from things like USB devices. You may end up seeing interfaces named like rename0 instead of the intended name. As the default behaviour is predictable network interface names and there are problems with these interface names, predictable interface names should be preferred when possible.

Manual installation¶

Nodes may also be installed manually by following the instructions on the node setup page. As of version 6.8, nodes can be installed on devices running openSUSE Leap 15.6, 15.5, or 15.4, or Debian 12, 11, or 10.
