Chapter 17. Network [config.openshift.io/v1]

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.

networkDiagnostics

object

networkDiagnostics defines network diagnostics configuration. Takes precedence over spec.disableNetworkDiagnostics in network.operator.openshift.io. If networkDiagnostics is not specified or is empty, and the spec.disableNetworkDiagnostics flag in network.operator.openshift.io is set to true, the network diagnostics feature will be disabled.

networkType

string

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

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.

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.

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.

mode

string

mode controls the network diagnostics mode When omitted, this means the user has no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. The current default is All.

sourcePlacement

object

sourcePlacement controls the scheduling of network diagnostics source deployment See NetworkDiagnosticsSourcePlacement for more details about default values.

targetPlacement

object

targetPlacement controls the scheduling of network diagnostics target daemonset See NetworkDiagnosticsTargetPlacement for more details about default values.

nodeSelector

object (string)

nodeSelector is the node selector applied to network diagnostics components When omitted, this means the user has no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. The current default is kubernetes.io/os: linux.

tolerations

array

tolerations is a list of tolerations applied to network diagnostics components When omitted, this means the user has no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. The current default is an empty list.

tolerations[]

object

The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator <operator>.

effect

string

Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute.

key

string

Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys.

operator

string

Operator represents a key’s relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category.

tolerationSeconds

integer

TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system.

value

string

Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string.

nodeSelector

object (string)

nodeSelector is the node selector applied to network diagnostics components When omitted, this means the user has no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. The current default is kubernetes.io/os: linux.

tolerations

array

tolerations is a list of tolerations applied to network diagnostics components When omitted, this means the user has no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. The current default is - operator: "Exists" which means that all taints are tolerated.

tolerations[]

object

The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator <operator>.

effect

string

Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute.

key

string

Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys.

operator

string

Operator represents a key’s relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category.

tolerationSeconds

integer

TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system.

value

string

Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string.

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.

conditions

array

conditions represents the observations of a network.config current state. Known .status.conditions.type are: "NetworkDiagnosticsAvailable"

conditions[]

object

Condition contains details for one aspect of the current state of this API Resource. --- This struct is intended for direct use as an array at the field path .status.conditions. For example, type FooStatus struct{ // Represents the observations of a foo’s current state. // Known .status.conditions.type are: "Available", "Progressing", and "Degraded" // +patchMergeKey=type // +patchStrategy=merge // +listType=map // +listMapKey=type Conditions []metav1.Condition json:"conditions,omitempty" patchStrategy:"merge" patchMergeKey:"type" protobuf:"bytes,1,rep,name=conditions" // other fields }

migration

object

Migration contains the cluster network migration configuration.

networkType

string

NetworkType is the plugin that is deployed (e.g. OVNKubernetes).

serviceNetwork

array (string)

IP address pool for services. Currently, we only support a single entry here.

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.

lastTransitionTime

string

lastTransitionTime is the last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.

message

string

message is a human readable message indicating details about the transition. This may be an empty string.

observedGeneration

integer

observedGeneration represents the .metadata.generation that the condition was set based upon. For instance, if .metadata.generation is currently 12, but the .status.conditions[x].observedGeneration is 9, the condition is out of date with respect to the current state of the instance.

reason

string

reason contains a programmatic identifier indicating the reason for the condition’s last transition. Producers of specific condition types may define expected values and meanings for this field, and whether the values are considered a guaranteed API. The value should be a CamelCase string. This field may not be empty.

status

string

status of the condition, one of True, False, Unknown.

type

string

type of condition in CamelCase or in foo.example.com/CamelCase. --- Many .condition.type values are consistent across resources like Available, but because arbitrary conditions can be useful (see .node.status.conditions), the ability to deconflict is important. The regex it matches is (dns1123SubdomainFmt/)?(qualifiedNameFmt)

mtu

object

MTU is the MTU configuration that is being deployed.

networkType

string

NetworkType is the target plugin that is being deployed. DEPRECATED: network type migration is no longer supported, so this should always be unset.

machine

object

Machine contains MTU migration configuration for the machine’s uplink.

network

object

Network contains MTU migration configuration for the default network.

from

integer

From is the MTU to migrate from.

to

integer

To is the MTU to migrate to.

from

integer

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

fieldValidation

string

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.
