Use a local node network in a swarm¶
Mirantis Kubernetes Engine (MKE) can use local network drivers to orchestrate your cluster. You can create a config network with a driver such as MAC VLAN, and use this network in the same way as any other named network in MKE. In addition, if it is set up as attachable you can attach containers.
Encrypting communication between containers on different nodes only works with overlay networks.
Create node-specific networks with MKE¶
To create a node-specific network for use with MKE, always do so through MKE, using either the MKE web UI or the CLI with an admin bundle. If you create such a network without MKE, it will not have the correct access label and it will not be available in MKE.
Create a MAC VLAN network¶
Log in to the MKE web UI as an administrator.
In the left-side navigation menu, click Swarm > Networks.
Click Create to call the Create Network screen.
Select macvlan from the Drivers` dropdown.
Enter macvlan into the Name field.
Select the type of network to create, Network or Local Config.
If you select Local Config, the SCOPE is automatically set to Local. You subsequently select the nodes for which to create the Local Config from those listed. MKE will prefix the network with the node name for each selected node to ensure consistent application of access labels, and you then select a Collection for the Local Configs to reside in. All Local Configs with the same name must be in the same collection, or MKE returns an error. If you do not not select a Collection, the network is placed in your default collection, which is
/in a new MKE installation.
If you select Network, the SCOPE is automatically set to Swarm. Choose an existing Local Config from which to create the network. The network and its labels and collection placement are inherited from the related Local Configs.
Optional. Configure IPAM.
