Self-service networks

updated: 2021-03-22 13:40

Self-service networks¶

A self-service (project) network includes only virtual components, thus enabling projects to manage them without additional configuration of the underlying physical network. The OVN mechanism driver supports Geneve and VLAN network types with a preference toward Geneve. Projects can choose to isolate self-service networks, connect two or more together via routers, or connect them to provider networks via routers with appropriate capabilities. Similar to provider networks, self-service networks can use arbitrary names.

Note

Similar to provider networks, self-service VLAN networks map to a unique bridge on each compute node that supports launching instances on those networks. Self-service VLAN networks also require several commands at the host and OVS levels. The following example assumes use of Geneve self-service networks.

Create a self-service network¶

Creating a self-service network involves several commands at the Networking service level that yield a series of operations at the OVN level to create the virtual network components. The following example creates a Geneve self-service network and binds a subnet to it. The subnet uses DHCP to distribute IP addresses to instances.

On the controller node, source the credentials for a regular (non-privileged) project. The following example uses the demo project.

On the controller node, create a self-service network in the Networking service.

OVN operations¶

The OVN mechanism driver and OVN perform the following operations during creation of a self-service network.

The mechanism driver translates the network into a logical switch in the OVN northbound database.

ports               : []

The OVN northbound service translates this object into new datapath bindings and logical flows in the OVN southbound database.

These actions do not create flows on any nodes.

Create a subnet on the self-service network¶

A self-service network requires at least one subnet. In most cases, the environment provides suitable values for IP address allocation for instances, default gateway IP address, and metadata such as name resolution.

On the controller node, create a subnet bound to the self-service network selfservice.

OVN operations¶

The OVN mechanism driver and OVN perform the following operations during creation of a subnet on a self-service network.

If the subnet uses DHCP for IP address management, create logical ports ports for each DHCP agent serving the subnet and bind them to the logical switch. In this example, the subnet contains two DHCP agents.

The OVN northbound service creates port bindings for these logical ports and adds them to the appropriate multicast group.
