Create a MOSK cluster

With L2 networking templates, you can create MOSK clusters with advanced host networking configurations. For example, you can create bond interfaces on top of physical interfaces on the host or use multiple subnets to separate different types of network traffic.

You can use several host-specific L2 templates per one cluster to support different hardware configurations. For example, you can create L2 templates with a different number and layout of NICs to be applied to specific machines of one cluster.

You can also use multiple L2 templates to support different roles for nodes in a MOSK installation. You can create L2 templates with different logical interfaces and assign them to individual machines based on their roles in a MOSK cluster.

When you create a baremetal-based project in the Container Cloud web UI, the exemplary templates with the ipam/PreInstalledL2Template label are copied to this project. These templates are preinstalled during the management cluster bootstrap.

Follow the procedures below to create MOSK clusters using L2 templates.

• Create a managed bare metal cluster
• Workflow of network interface naming
• Service labels and their life cycle
• Create subnets
• Create subnets for a MOSK cluster
• Create L2 templates
• Configure the MetalLB speaker node selector
