The module has 6 alerts.
The module is not enabled by default in any bundles.
The module is configured using the ModuleConfig custom resource named metallb (learn more about setting up Deckhouse…).

- array of objects
A list of IP ranges to assign to services.
Format — a data array similar to that of MetalLB’s.
Default:
[]- array of strings
Keys from the bgpCommunities parameter to be associated with the announcement.
Example:
communities: - no-advertise
- string
The name of the pool (you can specify it using the service annotation as follows:
metallb.universe.tf/address-pool: <name>). It should conform to RFC 1123: dot-separated parts in lowercase, consists of alphanumeric characters, ‘-‘. Each part must start and end with an alphanumeric character.Pattern:
^[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*$
- array of objects
A list of external BGP routers to use with the module.
Format — a data array similar to that of MetalLB’s.
The parameter is optional if only the
layer2mode is used to announce services.Default:
[]- integer or string
The timeout after which the neighboring BGP peer is considered dead. This value is divided by three to get the keep-alive interval.
The recommended value is
3s(i.e., keep-alive packets are sent once per second). Note that the BGP protocol does not support values lower than this. By default, the parameter is set to90s(i.e., keep-alive packets are sent every 30 seconds).Pattern:
^(0|(([0-9]+)y)?(([0-9]+)w)?(([0-9]+)d)?(([0-9]+)h)?(([0-9]+)m)?(([0-9]+)s)?(([0-9]+)ms)?)$ - object
The additional pseudo-selector implemented by the speaker application. It selects nodes that are allowed to connect to external BGP routers. Do not confuse it with
speaker.nodeSelectorandnodeSelector.An optional parameter.
The format is
matchLabelsormatchExpressions.
- object
A selector for the main controller. It is the same as the Pod’s
spec.nodeSelectorparameter in Kubernetes.If the parameter is omitted or
false, it will be determined automatically. - object
Parameters of the
speakercomponent, which announces services (usingbgporlayer2(LVS) routing protocol) and routes application traffic to its node.- object
Required value
A selector for the speaker DaemonSet. It is the same as the Pod’s
spec.nodeSelectorparameter in Kubernetes.If the parameter is omitted or
false, it will be determined automatically. - array of objects
Tolerations for the speaker DaemonSet. They are the same as the Pod’s
spec.tolerationsparameter in Kubernetes.If the parameter is omitted or
false, it will be determined automatically.
- array of objects
Tolerations for the main controller. They are the same as the Pod’s
spec.tolerationsparameter in Kubernetes.If the parameter is omitted or
false, it will be determined automatically.
