Azure Red Hat OpenShift 3.11 will be retired 30 June 2022. Support for creation of new Azure Red Hat OpenShift 3.11 clusters continues through 30 November 2020. Following retirement, remaining Azure Red Hat OpenShift 3.11 clusters will be shut down to prevent security vulnerabilities.

Follow this guide to create an Azure Red Hat OpenShift 4 cluster. If you have specific questions, please contact us


Description

HostSubnet describes the container subnet network on a node. The HostSubnet object must have the same name as the Node object it corresponds to.

Type

object

Required
  • host

  • hostIP

  • subnet

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/api-conventions.md#resources

.egressCIDRs

array (string)

EgressCIDRs is the list of CIDR ranges available for automatically assigning egress IPs to this node from. If this field is set then EgressIPs should be treated as read-only.

.egressIPs

array (string)

EgressIPs is the list of automatic egress IP addresses currently hosted by this node. If EgressCIDRs is empty, this can be set by hand; if EgressCIDRs is set then the master will overwrite the value here with its own allocation of egress IPs.

.host

string

Host is the name of the node. (This is the same as the object’s name, but both fields must be set.)

.hostIP

string

HostIP is the IP address to be used as a VTEP by other nodes in the overlay network

.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/api-conventions.md#types-kinds

.metadata

ObjectMeta meta/v1

Standard object’s metadata.

.subnet

string

Subnet is the CIDR range of the overlay network assigned to the node for its pods

HTTP method

DELETE

Description

Table 2. Query parameters
Parameter Type Description

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 previous 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 indicating the client must restart their list without the continue field. 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.

includeUninitialized

boolean

If true, partially initialized resources are included in the response.

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 next 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

When specified with a watch call, shows changes that occur after that particular version of a resource. Defaults to changes from the beginning of history. When specified for list: - if unset, then the result is returned from remote storage based on quorum-read flag; - if it's 0, then we simply return what we currently have in cache, no guarantee; - if set to non zero, then the result is at least as fresh as given rv.

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 10. Query parameters
Parameter Type Description

gracePeriodSeconds

integer

The duration in seconds before the object should be deleted. Value must be non-negative integer. 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.
