9.2. The OpenStack Cloud Controller Manager (CCM) config map

enabled

Whether or not to enable the LoadBalancer type of services integration. The default value is true.

floating-network-id

Optional. The external network used to create floating IP addresses for load balancer virtual IP addresses (VIPs). If there are multiple external networks in the cloud, this option must be set or the user must specify loadbalancer.openstack.org/floating-network-id in the service annotation.

floating-subnet-id

Optional. The external network subnet used to create floating IP addresses for the load balancer VIP. Can be overridden by the service annotation loadbalancer.openstack.org/floating-subnet-id.

floating-subnet

Optional. A name pattern (glob or regular expression if starting with ~) for the external network subnet used to create floating IP addresses for the load balancer VIP. Can be overridden by the service annotation loadbalancer.openstack.org/floating-subnet. If multiple subnets match the pattern, the first one with available IP addresses is used.

floating-subnet-tags

Optional. Tags for the external network subnet used to create floating IP addresses for the load balancer VIP. Can be overridden by the service annotation loadbalancer.openstack.org/floating-subnet-tags. If multiple subnets match these tags, the first one with available IP addresses is used.

If the RHOSP network is configured with sharing disabled, for example, with the --no-share flag used during creation, this option is unsupported. Set the network to share to use this option.

lb-method

The load balancing algorithm used to create the load balancer pool. For the Amphora provider the value can be ROUND_ROBIN, LEAST_CONNECTIONS, or SOURCE_IP. The default value is ROUND_ROBIN.

For the OVN provider, only the SOURCE_IP_PORT algorithm is supported.

For the Amphora provider, if using the LEAST_CONNECTIONS or SOURCE_IP methods, configure the create-monitor option as true in the cloud-provider-config config map on the openshift-config namespace and ETP:Local on the load-balancer type service to allow balancing algorithm enforcement in the client to service endpoint connections.

lb-provider

Optional. Used to specify the provider of the load balancer, for example, amphora or octavia. Only the Amphora and Octavia providers are supported.

lb-version

Optional. The load balancer API version. Only "v2" is supported.

subnet-id

The ID of the Networking service subnet on which load balancer VIPs are created.

network-id

The ID of the Networking service network on which load balancer VIPs are created. Unnecessary if subnet-id is set.

create-monitor

Whether or not to create a health monitor for the service load balancer. A health monitor is required for services that declare externalTrafficPolicy: Local. The default value is false.

This option is unsupported if you use RHOSP earlier than version 17 with the ovn provider.

monitor-delay

The interval in seconds by which probes are sent to members of the load balancer. The default value is 5.

monitor-max-retries

The number of successful checks that are required to change the operating status of a load balancer member to ONLINE. The valid range is 1 to 10, and the default value is 1.

monitor-timeout

The time in seconds that a monitor waits to connect to the back end before it times out. The default value is 3.

internal-lb

Whether or not to create an internal load balancer without floating IP addresses. The default value is false.

LoadBalancerClass "ClassName"

This is a config section that comprises a set of options:

The behavior of these options is the same as that of the identically named options in the load balancer section of the CCM config file.

You can set the ClassName value by specifying the service annotation loadbalancer.openstack.org/class.

max-shared-lb

The maximum number of services that can share a load balancer. The default value is 2.
