Description

EgressFirewall describes the current egress firewall for a Namespace. Traffic from a pod to an IP address outside the cluster will be checked against each EgressFirewallRule in the pod’s namespace’s EgressFirewall, in order. If no rule matches (or no EgressFirewall is present) then the traffic will be allowed by default.

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

Type

object

Property Type Description

cidrSelector

string

cidrSelector is the CIDR range to allow/deny traffic to. If this is set, dnsName and nodeSelector must be unset.

dnsName

string

dnsName is the domain name to allow/deny traffic to. If this is set, cidrSelector and nodeSelector must be unset. For a wildcard DNS name, the '' will match only one label. Additionally, only a single '' can be used at the beginning of the wildcard DNS name. For example, '*.example.com' will match 'sub1.example.com' but won’t match 'sub2.sub1.example.com'

nodeSelector

object

nodeSelector will allow/deny traffic to the Kubernetes node IP of selected nodes. If this is set, cidrSelector and DNSName must be unset.

.spec.egress[].to.nodeSelector

Description

nodeSelector will allow/deny traffic to the Kubernetes node IP of selected nodes. If this is set, cidrSelector and DNSName must be unset.

Property Type Description

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.

.spec.egress[].to.nodeSelector.matchExpressions

Description

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

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.

Table 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

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.
