Fields

action

Required

string

The Action to perform when the client connection triggers the rule. Can currently be either "allow" or "deny()" where valid values for status are 403, 404, and 502.

description

Optional

string

An optional description for this resource.

direction

Required

string

The direction in which this rule applies. Possible values: INGRESS, EGRESS

disabled

Optional

boolean

Denotes whether the firewall policy rule is disabled. When set to true, the firewall policy rule is not enforced and traffic behaves as if it did not exist. If this is unspecified, the firewall policy rule will be enabled.

enableLogging

Optional

boolean

Denotes whether to enable logging for a particular rule. If logging is enabled, logs will be exported to the configured export destination in Stackdriver. Logs may be exported to BigQuery or Pub/Sub. Note: you cannot enable logging on "goto_next" rules.

firewallPolicyRef

Required

object

Immutable.

firewallPolicyRef.external

Optional

string

The firewall policy of the resource. Allowed value: The Google Cloud resource name of a `ComputeFirewallPolicy` resource (format: `locations/global/firewallPolicies/{{name}}`).

firewallPolicyRef.name

Optional

string

Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names

firewallPolicyRef.namespace

Optional

string

Namespace of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/

match

Required

object

A match condition that incoming traffic is evaluated against. If it evaluates to true, the corresponding 'action' is enforced.

match.destIPRanges

Optional

list (string)

CIDR IP address range. Maximum number of destination CIDR IP ranges allowed is 256.

match.destIPRanges[]

Optional

string

match.layer4Configs

Required

list (object)

Pairs of IP protocols and ports that the rule should match.

match.layer4Configs[]

Required

object

match.layer4Configs[].ipProtocol

Required

string

The IP protocol to which this rule applies. The protocol type is required when creating a firewall rule. This value can either be one of the following well known protocol strings (`tcp`, `udp`, `icmp`, `esp`, `ah`, `ipip`, `sctp`), or the IP protocol number.

match.layer4Configs[].ports

Optional

list (string)

An optional list of ports to which this rule applies. This field is only applicable for UDP or TCP protocol. Each entry must be either an integer or a range. If not specified, this rule applies to connections through any port. Example inputs include: ``.

match.layer4Configs[].ports[]

Optional

string

match.srcIPRanges

Optional

list (string)

CIDR IP address range. Maximum number of source CIDR IP ranges allowed is 256.

match.srcIPRanges[]

Optional

string

priority

Required

integer

Immutable. An integer indicating the priority of a rule in the list. The priority must be a positive value between 0 and 2147483647. Rules are evaluated from highest to lowest priority where 0 is the highest priority and 2147483647 is the lowest prority.

targetResources

Optional

list (object)

targetResources[]

Optional

object

targetResources[].external

Optional

string

Allowed value: The `selfLink` field of a `ComputeNetwork` resource.

targetResources[].name

Optional

string

Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names

targetResources[].namespace

Optional

string

Namespace of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/

targetServiceAccounts

Optional

list (object)

targetServiceAccounts[]

Optional

object

targetServiceAccounts[].external

Optional

string

Allowed value: The Google Cloud resource name of an `IAMServiceAccount` resource (format: `projects/{{project}}/serviceAccounts/{{name}}@{{project}}.iam.gserviceaccount.com`).

targetServiceAccounts[].name

Optional

string

Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names

targetServiceAccounts[].namespace

Optional

string

Namespace of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/

Status

Schema

conditions:
- lastTransitionTime: string
  message: string
  reason: string
  status: string
  type: string
kind: string
observedGeneration: integer
ruleTupleCount: integer
Fields
conditions

list (object)

Conditions represent the latest available observation of the resource's current state.

conditions[]

object

conditions[].lastTransitionTime

string

Last time the condition transitioned from one status to another.

conditions[].message

string

Human-readable message indicating details about last transition.

conditions[].reason

string

Unique, one-word, CamelCase reason for the condition's last transition.

conditions[].status

string

Status is the status of the condition. Can be True, False, Unknown.

conditions[].type

string

Type is the type of the condition.

kind

string

Type of the resource. Always `compute#firewallPolicyRule` for firewall policy rules

observedGeneration

integer

ObservedGeneration is the generation of the resource that was most recently observed by the Config Connector controller. If this is equal to metadata.generation, then that means that the current reported status reflects the most recent desired state of the resource.

ruleTupleCount

integer

Calculation of the complexity of a single firewall policy rule.
