Custom Resource Definitions API Reference

Packages

configuration.konghq.com/v1

Package v1 contains API Schema definitions for the konghq.com v1 API group.

KongClusterPlugin is the Schema for the kongclusterplugins API.

The only differences between KongPlugin and KongClusterPlugin are that KongClusterPlugin is a Kubernetes cluster-level resource instead of a namespaced resource, and can be applied as a global plugin using global label.

Field Description
apiVersion string configuration.konghq.com/v1
kind string KongClusterPlugin
metadata ObjectMeta Refer to Kubernetes API documentation for fields of metadata.
consumerRef string ConsumerRef is a reference to a particular consumer.
disabled boolean Disabled set if the plugin is disabled or not.
config JSON Config contains the plugin configuration. It’s a list of keys and values required to configure the plugin. Please read the documentation of the plugin being configured to set values in here. For any plugin in Kong, anything that goes in the config JSON key in the Admin API request, goes into this property. Only one of config or configFrom may be used in a KongClusterPlugin, not both at once.
configFrom NamespacedConfigSource ConfigFrom references a secret containing the plugin configuration. This should be used when the plugin configuration contains sensitive information, such as AWS credentials in the Lambda plugin or the client secret in the OIDC plugin. Only one of config or configFrom may be used in a KongClusterPlugin, not both at once.
configPatches NamespacedConfigPatch array ConfigPatches represents JSON patches to the configuration of the plugin. Each item means a JSON patch to add something in the configuration, where path is specified in path and value is in valueFrom referencing a key in a secret. When Config is specified, patches will be applied to the configuration in Config. Otherwise, patches will be applied to an empty object.
plugin string PluginName is the name of the plugin to which to apply the config.
run_on string RunOn configures the plugin to run on the first or the second or both nodes in case of a service mesh deployment.
protocols KongProtocol array Protocols configures plugin to run on requests received on specific protocols.
ordering PluginOrdering Ordering overrides the normal plugin execution order. It’s only available on Kong Enterprise. <phase> is a request processing phase (for example, access or body_filter) and <plugin> is the name of the plugin that will run before or after the KongPlugin. For example, a KongPlugin with plugin: rate-limiting and before.access: ["key-auth"] will create a rate limiting plugin that limits requests before they are authenticated.
instance_name string InstanceName is an optional custom name to identify an instance of the plugin. This is useful when running the same plugin in multiple contexts, for example, on multiple services.

KongConsumer

KongConsumer is the Schema for the kongconsumers API.

When this resource is created, a corresponding consumer entity will be created in Kong. While KongConsumer exists in a specific Kubernetes namespace, KongConsumers from all namespaces are combined into a single Kong configuration, and no KongConsumers with the same kubernetes.io/ingress.class may share the same Username or CustomID value.

Field Description
apiVersion string configuration.konghq.com/v1
kind string KongConsumer
metadata ObjectMeta Refer to Kubernetes API documentation for fields of metadata.
username string Username is a Kong cluster-unique username of the consumer.
custom_id string CustomID is a Kong cluster-unique existing ID for the consumer - useful for mapping Kong with users in your existing database.
credentials string array Credentials are references to secrets containing a credential to be provisioned in Kong.
consumerGroups string array ConsumerGroups are references to consumer groups (that consumer wants to be part of) provisioned in Kong.

KongIngress

KongIngress is the Schema for the kongingresses API.

It serves as an “extension” to Ingress resource. It is not meant as a replacement to the Ingress resource in Kubernetes. The Ingress resource spec in Kubernetes can define routing policies based on HTTP Host header and paths. While this is sufficient in most cases, sometimes, users may want more control over routing at the Ingress level. Once a KongIngress resource is created, it needs to be associated with an Ingress or Service resource using the konghq.com/override annotation.

KongIngress is not supported on Gateway APIs resources, such as HTTPRoute and TCPRoute. These resources must use annotations.

As of version 2.8, KongIngress sections other than upstream are deprecated. All settings in the proxy and route sections are now available with dedicated annotations, and these annotations will become the only means of configuring those settings in a future release. For example, if you had set proxy.connect_timeout: 30000 in a KongIngress and applied an konghq.com/override annotation for that KongIngress to a Service, you will need to instead apply a konghq.com/connect-timeout: 30000 annotation to the Service.

Plans are to replace the upstream section of KongIngress with a new resource, but this is still in development and upstream is not yet officially deprecated.

Field Description
apiVersion string configuration.konghq.com/v1
kind string KongIngress
metadata ObjectMeta Refer to Kubernetes API documentation for fields of metadata.
upstream KongIngressUpstream Upstream represents a virtual hostname and can be used to loadbalance incoming requests over multiple targets (e.g. Kubernetes Services can be a target, OR Endpoints can be targets).
proxy KongIngressService Proxy defines additional connection options for the routes to be configured in the Kong Gateway, e.g. connection_timeout, retries, etc.
route KongIngressRoute Route define rules to match client requests. Each Route is associated with a Service, and a Service may have multiple Routes associated to it.

KongPlugin

KongPlugin is the Schema for the kongplugins API.

Plugins can be associated with the Ingress, Service, HTTPRoute, KongConsumer or KongConsumerGroup object in Kubernetes using konghq.com/plugins annotation.

Field Description
apiVersion string configuration.konghq.com/v1
kind string KongPlugin
metadata ObjectMeta Refer to Kubernetes API documentation for fields of metadata.
consumerRef string ConsumerRef is a reference to a particular consumer.
disabled boolean Disabled set if the plugin is disabled or not.
config JSON Config contains the plugin configuration. It’s a list of keys and values required to configure the plugin. Please read the documentation of the plugin being configured to set values in here. For any plugin in Kong, anything that goes in the config JSON key in the Admin API request, goes into this property. Only one of config or configFrom may be used in a KongPlugin, not both at once.
configFrom ConfigSource ConfigFrom references a secret containing the plugin configuration. This should be used when the plugin configuration contains sensitive information, such as AWS credentials in the Lambda plugin or the client secret in the OIDC plugin. Only one of config or configFrom may be used in a KongPlugin, not both at once.
configPatches ConfigPatch array ConfigPatches represents JSON patches to the configuration of the plugin. Each item means a JSON patch to add something in the configuration, where path is specified in path and value is in valueFrom referencing a key in a secret. When Config is specified, patches will be applied to the configuration in Config. Otherwise, patches will be applied to an empty object.

KongUpstreamPolicy

KongUpstreamPolicy allows configuring algorithm that should be used for load balancing traffic between Kong Upstream’s Targets. It also allows configuring health checks for Kong Upstream’s Targets.

Its configuration is similar to Kong Upstream object (https://docs.konghq.com/gateway/latest/admin-api/#upstream-object), and it is applied to Kong Upstream objects created by the controller.

It can be attached to Services. To attach it to a Service, it has to be annotated with konghq.com/upstream-policy: <name>, where <name> is the name of the KongUpstreamPolicy object in the same namespace as the Service.

When attached to a Service, it will affect all Kong Upstreams created for the Service.

When attached to a Service used in a Gateway API Route rule with multiple BackendRefs, all of its Services MUST be configured with the same KongUpstreamPolicy. Otherwise, the controller will *ignore the KongUpstreamPolicy.

Note: KongUpstreamPolicy doesn’t implement Gateway API’s GEP-713 strictly. In particular, it doesn’t use the TargetRef for attaching to Services and Gateway API *Routes - annotations are used instead. This is to allow reusing the same KongUpstreamPolicy for multiple Services and Gateway API *Routes.
