Network [operator.openshift.io/v1]

additionalNetworks

array

additionalNetworks is a list of extra networks to make available to pods when multiple networks are enabled.

additionalNetworks[]

object

AdditionalNetworkDefinition configures an extra network that is available but not created by default. Instead, pods must request them by name. type must be specified, along with exactly one "Config" that matches the type.

clusterNetwork

array

clusterNetwork is the IP address pool to use for pod IPs. Some network providers, e.g. OpenShift SDN, support multiple ClusterNetworks. Others only support one. This is equivalent to the cluster-cidr.

clusterNetwork[]

object

ClusterNetworkEntry is a subnet from which to allocate PodIPs. A network of size HostPrefix (in CIDR notation) will be allocated when nodes join the cluster. If the HostPrefix field is not used by the plugin, it can be left unset. Not all network providers support multiple ClusterNetworks

defaultNetwork

object

defaultNetwork is the "default" network that all pods will receive

deployKubeProxy

boolean

deployKubeProxy specifies whether or not a standalone kube-proxy should be deployed by the operator. Some network providers include kube-proxy or similar functionality. If unset, the plugin will attempt to select the correct value, which is false when OpenShift SDN and ovn-kubernetes are used and true otherwise.

disableMultiNetwork

boolean

disableMultiNetwork specifies whether or not multiple pod network support should be disabled. If unset, this property defaults to 'false' and multiple network support is enabled.

disableNetworkDiagnostics

boolean

disableNetworkDiagnostics specifies whether or not PodNetworkConnectivityCheck CRs from a test pod to every node, apiserver and LB should be disabled or not. If unset, this property defaults to 'false' and network diagnostics is enabled. Setting this to 'true' would reduce the additional load of the pods performing the checks.

exportNetworkFlows

object

exportNetworkFlows enables and configures the export of network flow metadata from the pod network by using protocols NetFlow, SFlow or IPFIX. Currently only supported on OVN-Kubernetes plugin. If unset, flows will not be exported to any collector.

kubeProxyConfig

object

kubeProxyConfig lets us configure desired proxy configuration. If not specified, sensible defaults will be chosen by OpenShift directly. Not consumed by all network providers - currently only openshift-sdn.

logLevel

string

logLevel is an intent based logging for an overall component. It does not give fine grained control, but it is a simple way to manage coarse grained logging choices that operators have to interpret for their operands. Valid values are: "Normal", "Debug", "Trace", "TraceAll". Defaults to "Normal".

managementState

string

managementState indicates whether and how the operator should manage the component

migration

object

migration enables and configures the cluster network migration. Setting this to the target network type to allow changing the default network. If unset, the operation of changing cluster default network plugin will be rejected.

observedConfig

``

observedConfig holds a sparse config that controller has observed from the cluster state. It exists in spec because it is an input to the level for the operator

operatorLogLevel

string

operatorLogLevel is an intent based logging for the operator itself. It does not give fine grained control, but it is a simple way to manage coarse grained logging choices that operators have to interpret for themselves. Valid values are: "Normal", "Debug", "Trace", "TraceAll". Defaults to "Normal".

serviceNetwork

array (string)

serviceNetwork is the ip address pool to use for Service IPs Currently, all existing network providers only support a single value here, but this is an array to allow for growth.

unsupportedConfigOverrides

``

unsupportedConfigOverrides holds a sparse config that will override any previously set options. It only needs to be the fields to override it will end up overlaying in the following order: 1. hardcoded defaults 2. observedConfig 3. unsupportedConfigOverrides

useMultiNetworkPolicy

boolean

useMultiNetworkPolicy enables a controller which allows for MultiNetworkPolicy objects to be used on additional networks as created by Multus CNI. MultiNetworkPolicy are similar to NetworkPolicy objects, but NetworkPolicy objects only apply to the primary interface. With MultiNetworkPolicy, you can control the traffic that a pod can receive over the secondary interfaces. If unset, this property defaults to 'false' and MultiNetworkPolicy objects are ignored. If 'disableMultiNetwork' is 'true' then the value of this field is ignored.

name

string

name is the name of the network. This will be populated in the resulting CRD This must be unique.

namespace

string

namespace is the namespace of the network. This will be populated in the resulting CRD If not given the network will be created in the default namespace.

string

hostPrefix

integer

kuryrConfig

object

type is the type of network All NetworkTypes are supported except for NetworkTypeRaw

controllerProbesPort

integer

The port kuryr-controller will listen for readiness and liveness requests.

daemonProbesPort

integer

The port kuryr-daemon will listen for readiness and liveness requests.

enablePortPoolsPrepopulation

boolean

enablePortPoolsPrepopulation when true will make Kuryr prepopulate each newly created port pool with a minimum number of ports. Kuryr uses Neutron port pooling to fight the fact that it takes a significant amount of time to create one. Instead of creating it when pod is being deployed, Kuryr keeps a number of ports ready to be attached to pods. By default port prepopulation is disabled.

mtu

integer

mtu is the MTU that Kuryr should use when creating pod networks in Neutron. The value has to be lower or equal to the MTU of the nodes network and Neutron has to allow creation of tenant networks with such MTU. If unset Pod networks will be created with the same MTU as the nodes network has.

openStackServiceNetwork

string

openStackServiceNetwork contains the CIDR of network from which to allocate IPs for OpenStack Octavia’s Amphora VMs. Please note that with Amphora driver Octavia uses two IPs from that network for each loadbalancer - one given by OpenShift and second for VRRP connections. As the first one is managed by OpenShift’s and second by Neutron’s IPAMs, those need to come from different pools. Therefore openStackServiceNetwork needs to be at least twice the size of serviceNetwork, and whole serviceNetwork must be overlapping with openStackServiceNetwork. cluster-network-operator will then make sure VRRP IPs are taken from the ranges inside openStackServiceNetwork that are not overlapping with serviceNetwork, effectivly preventing conflicts. If not set cluster-network-operator will use serviceNetwork expanded by decrementing the prefix size by 1.

poolBatchPorts

integer

poolBatchPorts sets a number of ports that should be created in a single batch request to extend the port pool. The default is 3. For more information about port pools see enablePortPoolsPrepopulation setting.

poolMaxPorts

integer

poolMaxPorts sets a maximum number of free ports that are being kept in a port pool. If the number of ports exceeds this setting, free ports will get deleted. Setting 0 will disable this upper bound, effectively preventing pools from shrinking and this is the default value. For more information about port pools see enablePortPoolsPrepopulation setting.

poolMinPorts

integer

poolMinPorts sets a minimum number of free ports that should be kept in a port pool. If the number of ports is lower than this setting, new ports will get created and added to pool. The default is 1. For more information about port pools see enablePortPoolsPrepopulation setting.

enableUnidling

boolean

enableUnidling controls whether or not the service proxy will support idling and unidling of services. By default, unidling is enabled.

mode

string
