Parameters

The parent key for all of the following parameters is airlock_microgateway.

`namespace`

type	string
default	`syn-airlock-microgateway`

The namespace in which to deploy this component.

`install_method`

type	string
default	`helm`
possible values	`helm`, `olm`

The installation method for Airlock Microgateway. olm will create a subscription for the Airlock Microgateway from catalog.redhat.com/software/container-stacks/detail/67177f927cfedb209761e48f?gs=&q=airlock&rh-tabs-5gjs77yz5=rh-tab-3tk92bl2m#overview. If you use this method, you may want to configure olm. Openshift is required for this to work.

helm will install airlock-microgateway from the official helm chart. If you use this method, you may want to configure helm_values.

default	`${airlock_microgateway:gateway_listener_manager:tls_secret_name_annotation}`

The annotation to use on HTTPRoute resources to specify the name of the TLS secret to create the certificate in.

`create_certificate_annotation`

type	string
default	`airlock-microgateway.appuio.io/create-certificate`

The annotation to use on HTTPRoute resources to create a certificate automatically. Must be set to ANNOTATION: "true" in the resource annotations.

`gateway_default_cluster_issuer_annotation`

type	string
default	`airlock-microgateway.appuio.io/gateway-default-cluster-issuer`

`cluster_issuer_annotation`

type	string
default	`airlock-microgateway.appuio.io/cluster-issuer`

The annotation to use on HTTPRoute resources to specify the cluster issuer for certificates.

`issuer_annotation`

type

object

Configuration for Kubernetes Gateway API integration.

`enabled`

type	boolean
default	`true`

Whether to install the upstream Kubernetes Gateway API.

`version`

type	string
default	`v1.2.1`

The version of Kubernetes Gateway API to install.

`source`

type	string
default	`github.com/kubernetes-sigs/gateway-api/releases/download/${airlock_microgateway:gateway_api:version}/standard-install.yaml`

The source URL for the Kubernetes Gateway API installation.

`airlock_xopenshift`

type

object

Configuration for deploying patched Gateway API CRDs on OpenShift. This parameter allows us to deploy copies of upstream Gateway API CRDs in API group x-openshift.microgateway.airlock.com. This allows us — by leveraging Airlock Mircogateway’s support for CRDs in that API group — to deploy additional Gateway API CRDs on OpenShift without creating conflicts with the ingress-operator-managed Gateway API CRDs that are deployed on OpenShift >= 4.19.

This parameter only has an effect for install_method=olm.

`enabled`

type	boolean
default	`false`

Whether to deploy any patched Gateway API CRDs.

`version`

type	string
default	`v1.3.0`

The upstream Gateway API version of the CRDs that we want to patch.

`channel`

type	string
default	`experimental`

The upstream Gateway API channel for the CRDs to patch. Supported values are standard or experimental. Component compilation will error when another value is provided.

`crds`

type	object
default	`{"backendtlspolicies":"BACKEND_TLS_POLICY"}`

The list of CRD names for which the component will deploy a copy of the CRD in API group x-openshift.microgateway.airlock.com. The keys are expected to be CRD base names, such as backendtlspolicies. The component will always download the full <channel>-install.yaml from the specified Gateway API release but will only create copies of CRDs whose base name matches a key with a non-null value in this parameter.

The values are expected to be the identifying segment for the OLM operator environment variable which switches the CRD from API group gateway.networking.k8s.io to x-openshift.microgateway.airlock.com. For example, value BACKEND_TLS_POLICY results in environment variable GATEWAY_API_BACKEND_TLS_POLICY_API_GROUP=x-openshift.microgateway.airlock.com to be set for the OLM operator.

Users can remove entries in this parameter by setting an entry to null.

`gateway_classes`

type

object

Configuration for Gateway Classes.

`gateway_classes.<name>.parametersRef`

type

string

A reference to a Gateway Parameters object, defined in gateway_parameters.

Example

airlock_microgateway:
  gateway_classes:
    my-gateway-class:
      spec:
        controllerName: microgateway.airlock.com/gatewayclass-controller
        parametersRef:
          group: microgateway.airlock.com
          kind: GatewayParameters
          name: gatewayparameter-mgw-poc
          namespace: airlock-gateway

    my-other-gateway-class:
      parametersRef: airlock

  gateway_parameters:
    airlock: ...

`gateway_parameters`

type

object

Configuration for Gateway Parameters.

Example

airlock_microgateway:
  gateway_parameters:
    airlock:
      spec:
        defaults:
          downstream:
            remoteIP:
              xff:
                numTrustedHops: 1
        kubernetes:
          deployment:
            automountServiceAccountToken: false
            engineContainer: {}
            placement: {}
            replicas: 1
          service:
            type: ClusterIP
        logging:
          level: info

`gateways`

type	object
default	`{}`

This parameter allows users to define Gateway resources to deploy. The component currently doesn’t validate that the value of spec.gatewayClassName is a gateway class that’s managed through parameter gateway_classes.

Airlock Microgateway also supports referencing a GatewayParameters resource directly in spec.infrastructure.parametersRef. If both spec.gatewayClassName and spec.infrastructure.parametersRef are provided, the instance is configured with the parameters referenced in spec.infrastructure.parametersRef.

See the Gateway API and Airlock Microgateway documentation for a full reference of supported configuration options for Gateway resources.

When component cilium is installed in the cluster, the component also creates a CiliumNetworkPolicy which allows traffic from identity world for each managed Gateway resource.

Example

airlock_microgateway:
  gateways:
    airlock/gateway-1:
      spec:
        gatewayClassName: airlock-microgateway
        listeners:
          - allowedRoutes:
              namespaces:
                from: All
            name: http
            port: 80
            protocol: HTTP

  gateway_parameters:
    airlock/gatewayparams: { ... }

  gateway_classes:
    airlock-microgateway:
      parametersRef: "airlock/gatewayparams"

`alerts`

type

object

This parameter allows users to disable or patch alerts managed by the component.

The component currently expects that an openshift4-monitoring-style alert patching library is available for the target cluster’s distribution’s monitoring stack.

`alerts.ignoreNames`

type	list
default	`[]`

Users can add alert names which they want to disable in this list.

`alerts.patches`

type	object
default	`{}`

Users can customize alerts through this parameter. The component looks for alert names it knows in this parameter, and applies the provided value, if any, over the default alert configuration.

`helm_values`

type	object
default

operator:
  gatewayAPI:
    enabled: true
    podMonitor:
      create: true
      labels:
