Network [config.openshift.io/v1]
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).

|
| 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 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 |
| Standard object’s metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata | |
|
| 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 holds observed values from the cluster. They may not be overridden. |

| IP address pool to use for pod IPs. This field is immutable after installation. |
|
| ClusterNetworkEntry is a contiguous block of IP addresses from which pod IPs are allocated. |
|
| externalIP defines configuration for controllers that affect Service.ExternalIP. If nil, then ExternalIP is not allowed to be set. |
|
| 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. |
|
| IP address pool for services. Currently, we only support a single entry here. This field is immutable after installation. |
|
| 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. |

|
| 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 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.

Parameter | Type | Description |

|
| When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed |
|
| fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered. |
