Description
EgressIP is a CRD allowing the user to define a fixed source IP for all egress traffic originating from any pods which match the EgressIP resource according to its spec definition.

5.1. Specification

PropertyTypeDescription

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

Specification of the desired behavior of EgressIP.

status

object

Observed status of EgressIP. Read-only.

5.1.1. .spec

Description
Specification of the desired behavior of EgressIP.
Type
object
Required
  • egressIPs
  • namespaceSelector
PropertyTypeDescription

egressIPs

array (string)

EgressIPs is the list of egress IP addresses requested. Can be IPv4 and/or IPv6. This field is mandatory.

namespaceSelector

object

NamespaceSelector applies the egress IP only to the namespace(s) whose label matches this definition. This field is mandatory.

podSelector

object

PodSelector applies the egress IP only to the pods whose label matches this definition. This field is optional, and in case it is not set: results in the egress IP being applied to all pods in the namespace(s) matched by the NamespaceSelector. In case it is set: is intersected with the NamespaceSelector, thus applying the egress IP to the pods (in the namespace(s) already matched by the NamespaceSelector) which match this pod selector.

5.1.2. .spec.namespaceSelector

Description
NamespaceSelector applies the egress IP only to the namespace(s) whose label matches this definition. This field is mandatory.
Type
object
PropertyTypeDescription

matchExpressions

array

matchExpressions is a list of label selector requirements. The requirements are ANDed.

matchExpressions[]

object

A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values.

matchLabels

object (string)

matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed.

5.1.3. .spec.namespaceSelector.matchExpressions

Description
matchExpressions is a list of label selector requirements. The requirements are ANDed.
Type
array

5.1.4. .spec.namespaceSelector.matchExpressions[]

Description
A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values.
Type
object
Required
  • key
  • operator
PropertyTypeDescription

key

string

key is the label key that the selector applies to.

operator

string

operator represents a key’s relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.

values

array (string)

values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch.

5.1.5. .spec.podSelector

Description
PodSelector applies the egress IP only to the pods whose label matches this definition. This field is optional, and in case it is not set: results in the egress IP being applied to all pods in the namespace(s) matched by the NamespaceSelector. In case it is set: is intersected with the NamespaceSelector, thus applying the egress IP to the pods (in the namespace(s) already matched by the NamespaceSelector) which match this pod selector.

    • DELETE: delete collection of EgressIP
    • GET: list objects of kind EgressIP
    • POST: create an EgressIP
  • /apis/k8s.ovn.org/v1/egressips/{name}

    • DELETE: delete an EgressIP
    • GET: read the specified EgressIP
    • PATCH: partially update the specified EgressIP
    • PUT: replace the specified EgressIP

Table 5.3. Query parameters
ParameterTypeDescription

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.
