IPAddressPool
Scope: Namespaced
Version: v1beta1
IPAddressPool represents a pool of IP addresses that can be allocated to LoadBalancer services.
- apiVersion
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
- kind
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
- metadata
- spec
Required value
IPAddressPoolSpec defines the desired state of IPAddressPool.
- spec.addresses
Required value
A list of IP address ranges over which MetalLB has authority. You can list multiple ranges in a single pool, they will all share the same settings. Each range can be either a CIDR prefix, or an explicit start-end range of IPs.
- spec.autoAssign
AutoAssign flag used to prevent MetalLB from automatic allocation for a pool.
Default:
true
- spec.avoidBuggyIPs
AvoidBuggyIPs prevents addresses ending with .0 and .255 to be used by a pool.
Default:
false
L2Advertisement
Scope: Namespaced
Version: v1beta1
L2Advertisement allows to advertise the LoadBalancer IPs provided by the selected pools via L2.
- apiVersion
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

- spec
L2AdvertisementSpec defines the desired state of L2Advertisement.
- spec.interfaces
A list of interfaces to announce from. The LB IP will be announced only from these interfaces. If the field is not set, we advertise from all the interfaces on the host.
- spec.ipAddressPoolSelectors
A selector for the IPAddressPools which would get advertised via this advertisement. If no IPAddressPool is selected by this or by the list, the advertisement is applied to all the IPAddressPools.
A label selector is a label query over a set of resources. The result of matchLabels and matchExpressions are ANDed. An empty label selector matches all objects. A null label selector matches no objects.
- spec.ipAddressPoolSelectors.matchExpressions
matchExpressions is a list of label selector requirements. The requirements are ANDed.
A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values.
- spec.ipAddressPoolSelectors.matchExpressions.key
Required value
key is the label key that the selector applies to.
- spec.ipAddressPoolSelectors.matchExpressions.operator
Required value
operator represents a key’s relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
- spec.ipAddressPoolSelectors.matchExpressions.values
values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch.
- spec.ipAddressPoolSelectors.matchLabels
matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is “key”, the operator is “In”, and the values array contains only “value”. The requirements are ANDed.
- spec.ipAddressPools
The list of IPAddressPools to advertise via this advertisement, selected by name.
- spec.nodeSelectors
NodeSelectors allows to limit the nodes to announce as next hops for the LoadBalancer IP. When empty, all the nodes having are announced as next hops.
A label selector is a label query over a set of resources. The result of matchLabels and matchExpressions are ANDed. An empty label selector matches all objects. A null label selector matches no objects.
- spec.nodeSelectors.matchExpressions
matchExpressions is a list of label selector requirements. The requirements are ANDed.
A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values.
- spec.nodeSelectors.matchExpressions.key
Required value
key is the label key that the selector applies to.
- spec.nodeSelectors.matchExpressions.operator
Required value
operator represents a key’s relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
- spec.nodeSelectors.matchExpressions.values
values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch.
- spec.nodeSelectors.matchLabels
matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is “key”, the operator is “In”, and the values array contains only “value”. The requirements are ANDed.
L2LoadBalancer
Scope: Cluster
Version: v1alpha1
L2LoadBalancer is the Schema for the l2loadbalancers API
- apiVersion
- kind
- metadata
- spec
- spec.addressPool
An array of public IP address ranges. Each range can be specified using a CIDR notation or by directly specifying the range, for example,
10.10.10.1-10.10.10.100
.Examples:
addressPool: 10.42.0.0/24
addressPool: 10.33.5.100-10.33.5.106
- spec.interfaces
A list of network interfaces from which the assigned IP addresses will be announced. If this field is not filled in or an empty array is specified, the announcement will occur from all interfaces on the node.
Examples:
interfaces: eth1
interfaces: eth2
- spec.nodeSelector
Allows restricting the list of nodes from which the announcement will occur. Specified as a set of labels for filtering nodes.
