Chapter 15. 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). Type object Required spec 15.1. 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 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. 15.1.1. .spec Description 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. 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. 15.1.2. .spec.clusterNetwork Description IP address pool to use for pod IPs. This field is immutable after installation. Type array 15.1.3. .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. 15.1.4. .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. 15.1.5. .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. 15.1.6. .status Description 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. clusterNetwork[] object ClusterNetworkEntry is a contiguous block of IP addresses from which pod IPs are allocated. clusterNetworkMTU integer ClusterNetworkMTU is the MTU for inter-pod networking. migration object Migration contains the cluster network migration configuration. networkType string NetworkType is the plugin that is deployed (e.g. OpenShiftSDN). serviceNetwork array (string) IP address pool for services. Currently, we only support a single entry here. 15.1.7. .status.clusterNetwork Description IP address pool to use for pod IPs.

API endpoints The following API endpoints are available: /apis/config.openshift.io/v1/networks DELETE : delete collection of Network GET : list objects of kind Network POST : create a Network /apis/config.openshift.io/v1/networks/{name} DELETE : delete a Network GET : read the specified Network PATCH : partially update the specified Network PUT : replace the specified Network 15.2.1. /apis/config.openshift.io/v1/networks Table 15.1. Global query parameters Parameter Type Description pretty string If 'true', then the output is pretty printed. HTTP method DELETE Description delete collection of Network Table 15.2. Query parameters Parameter Type Description allowWatchBookmarks boolean allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored. continue string The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the key, but from the latest snapshot, which is inconsistent from the list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the " key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications. fieldSelector string A selector to restrict the list of returned objects by their fields. Defaults to everything. labelSelector string A selector to restrict the list of returned objects by their labels. Defaults to everything. limit integer limit is a maximum number of responses to return for a list call. If more items exist, the server will set the continue field on the list metadata to a value that can be used with the same initial query to retrieve the set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned. resourceVersion string resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset resourceVersionMatch string resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset timeoutSeconds integer Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity. watch boolean Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion. Table 15.3. HTTP responses HTTP code Reponse body 200 - OK Status schema 401 - Unauthorized Empty HTTP method GET Description list objects of kind Network Table 15.4.

Query parameters Parameter Type Description dryRun string 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 fieldManager string fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint . fieldValidation string fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields, provided that the ServerSideFieldValidation feature gate is also enabled. 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 and is the default behavior when the ServerSideFieldValidation feature gate is disabled. - 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 when the ServerSideFieldValidation feature gate is enabled. - 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. Table 15.7. Body parameters Parameter Type Description body Network schema Table 15.8.

The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately. orphanDependents boolean Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both. propagationPolicy string Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
