Description

Network holds cluster-wide information about Network. The canonical name is cluster. It is used to configure the desired network configuration, such as: IP address pools for services/pod IPs, network plugin, etc. Please view network.spec for an explanation on what applies when configuring this resource. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

Specification

Property Type Description

apiVersion

string

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

string

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

ObjectMeta_v2

Standard object’s metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

spec

object

spec holds user settable values for configuration. As a general rule, this SHOULD NOT be read directly. Instead, you should consume the NetworkStatus, as it indicates the currently deployed configuration. Currently, most spec fields are immutable after installation. Please view the individual ones for further details on each.

status

object

status holds observed values from the cluster. They may not be overridden.

Type

object

Property Type Description

clusterNetwork

array

IP address pool to use for pod IPs. This field is immutable after installation.

clusterNetwork[]

object

ClusterNetworkEntry is a contiguous block of IP addresses from which pod IPs are allocated.

externalIP

object

externalIP defines configuration for controllers that affect Service.ExternalIP. If nil, then ExternalIP is not allowed to be set.

networkType

string

NetworkType is the plugin that is to be deployed (e.g. OpenShiftSDN). This should match a value that the cluster-network-operator understands, or else no networking will be installed. Currently supported values are: - OpenShiftSDN This field is immutable after installation.

serviceNetwork

array (string)

IP address pool for services. Currently, we only support a single entry here. This field is immutable after installation.

serviceNodePortRange

string

The port range allowed for Services of type NodePort. If not specified, the default of 30000-32767 will be used. Such Services without a NodePort specified will have one automatically allocated from this range. This parameter can be updated after the cluster is installed.

.spec.clusterNetwork

Description

IP address pool to use for pod IPs. This field is immutable after installation.

Type

array

.spec.clusterNetwork[]

Description

ClusterNetworkEntry is a contiguous block of IP addresses from which pod IPs are allocated.

Type

object

Property Type Description

cidr

string

The complete block for pod IPs.

hostPrefix

integer

The size (prefix) of block to allocate to each node. If this field is not used by the plugin, it can be left unset.

.spec.externalIP

Description

externalIP defines configuration for controllers that affect Service.ExternalIP. If nil, then ExternalIP is not allowed to be set.

Type

object

Property Type Description

autoAssignCIDRs

array (string)

autoAssignCIDRs is a list of CIDRs from which to automatically assign Service.ExternalIP. These are assigned when the service is of type LoadBalancer. In general, this is only useful for bare-metal clusters. In OpenShift 3.x, this was misleadingly called "IngressIPs". Automatically assigned External IPs are not affected by any ExternalIPPolicy rules. Currently, only one entry may be provided.

policy

object

policy is a set of restrictions applied to the ExternalIP field. If nil or empty, then ExternalIP is not allowed to be set.

.spec.externalIP.policy

Description

policy is a set of restrictions applied to the ExternalIP field. If nil or empty, then ExternalIP is not allowed to be set.

Type

object

Property Type Description

allowedCIDRs

array (string)

allowedCIDRs is the list of allowed CIDRs.

rejectedCIDRs

array (string)

rejectedCIDRs is the list of disallowed CIDRs. These take precedence over allowedCIDRs.

.status

Description

status holds observed values from the cluster. They may not be overridden.
