Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Now, the MOSK documentation set covers all product layers, including MOSK management (formerly Container Cloud). This means everything you need is in one place. Some legacy names may remain in the code and documentation and will be updated in future releases. The separate Container Cloud documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Assign L2 templates to machines¶

To deploy MOSK on bare metal, you must create L2 templates for each node type in the MOSK cluster. Additionally, you may have to create separate templates for nodes of the same type when they have different configuration.

To assign specific L2 templates to machines in a cluster:

Assign the templates to the cluster using the cluster.sigs.k8s.io/cluster-name label in the labels section.
Add a unique identifier label to every L2 template. Typically, that would be the name of the MOSK node role, for example l2template-compute, or l2template-compute-5nics.
Assign an L2 template to a machine. Set the l2TemplateSelector field in the machine spec to the name of the label added in the previous step. IPAM Controller uses this field to use a specific L2 template for the corresponding machine.

Alternatively, you may set the l2TemplateSelector field to the name of the L2 template.

Consider the following examples of an L2 template assignment to a machine.

Example of an L2Template resource¶

apiVersion: ipam.mirantis.com/v1alpha1
kind: L2Template
metadata:
  name: example-node-netconfig
  namespace: my-project
  labels:
    kaas.mirantis.com/provider: baremetal
    l2template-example-node-netconfig: "1"
    cluster.sigs.k8s.io/cluster-name: my-cluster
    ...

Example of a Machine resource with the label-based L2 template selector¶

apiVersion: cluster.k8s.io/v1alpha1
kind: Machine
metadata:
  name: machine1
  namespace: my-project
  labels:
    cluster.sigs.k8s.io/cluster-name: my-cluster
    ...
...
spec:
  providerSpec:
    value:
      l2TemplateSelector:
        label: l2template-example-node-netconfig
...

Example of a Machine resource with the name-based L2 template selector¶

apiVersion: cluster.k8s.io/v1alpha1
kind: Machine
metadata:
  name: machine1
  namespace: my-project
  labels:
    cluster.sigs.k8s.io/cluster-name: my-cluster
    ...
...
spec:
  providerSpec:
    value:
      l2TemplateSelector:
        name: example-node-netconfig
...

Now, proceed to Deploy a machine to a specific bare metal host.
