Deployment Mode
12 minute read
Deployment modes
One GatewayClass per Envoy Gateway Controller
- An Envoy Gateway is associated with a single GatewayClass resource under one controller. This is the simplest deployment mode and is suitable for scenarios where each Gateway needs to have its own dedicated set of resources and configurations.
Multiple GatewayClasses per Envoy Gateway Controller
- An Envoy Gateway is associated with multiple GatewayClass resources under one controller.
- Support for accepting multiple GatewayClasses was added here.
Separate Envoy Gateway Controllers
If you’ve instantiated multiple GatewayClasses, you can also run separate Envoy Gateway controllers in different namespaces, linking a GatewayClass to each of them for multi-tenancy. Please follow the example Multi-tenancy.
Merged Gateways onto a single EnvoyProxy fleet
By default, each Gateway has its own dedicated set of Envoy Proxy and its configurations. However, for some deployments, it may be more convenient to merge listeners across multiple Gateways and deploy a single Envoy Proxy fleet.
This can help to efficiently utilize the infra resources in the cluster and manage them in a centralized manner, or have a single IP address for all of the listeners.
Setting the mergeGateways
field in the EnvoyProxy resource linked to GatewayClass will result in merging all Gateway listeners under one GatewayClass resource.
- The tuple of port, protocol, and hostname must be unique across all Listeners.
Please follow the example Merged gateways deployment.
Supported Modes
Kubernetes
- The default deployment model is - Envoy Gateway watches for resources such a
Service
&HTTPRoute
in all namespaces and creates managed data plane resources such as EnvoyProxyDeployment
in the namespace where Envoy Gateway is running. - Envoy Gateway also supports Namespaced deployment mode, you can watch resources in the specific namespaces by assigning
EnvoyGateway.provider.kubernetes.watch.namespaces
orEnvoyGateway.provider.kubernetes.watch.namespaceSelector
and creates managed data plane resources in the namespace where Envoy Gateway is running. - Support for alternate deployment modes is being tracked here.
Multi-tenancy
Kubernetes
A
tenant
is a group within an organization (e.g. a team or department) who shares organizational resources. We recommend eachtenant
deploy their own Envoy Gateway controller in their respectivenamespace
. Below is an example of deploying Envoy Gateway by themarketing
andproduct
teams in separate namespaces.Lets deploy Envoy Gateway in the
marketing
namespace and also watch resources only in this namespace. We are also setting the controller name to a unique string heregateway.envoyproxy.io/marketing-gatewayclass-controller
.
helm install \
--set config.envoyGateway.gateway.controllerName=gateway.envoyproxy.io/marketing-gatewayclass-controller \
--set config.envoyGateway.provider.kubernetes.watch.type=Namespaces \
--set config.envoyGateway.provider.kubernetes.watch.namespaces={marketing} \
eg-marketing oci://docker.io/envoyproxy/gateway-helm \
--version v1.1.2 -n marketing --create-namespace
Lets create a GatewayClass
linked to the marketing team’s Envoy Gateway controller, and as well other resources linked to it, so the backend
application operated by this team can be exposed to external clients.

Merged gateways deployment
In this example, we will deploy GatewayClass
apiVersion: gateway.networking.k8s.io/v1
kind: GatewayClass
metadata:
name: merged-eg
spec:
controllerName: gateway.envoyproxy.io/gatewayclass-controller
parametersRef:
group: gateway.envoyproxy.io
kind: EnvoyProxy
name: custom-proxy-config
namespace: envoy-gateway-system
with a referenced EnvoyProxy resource configured to enable merged Gateways deployment mode.
apiVersion: gateway.envoyproxy.io/v1alpha1
kind: EnvoyProxy
metadata:
name: custom-proxy-config
namespace: envoy-gateway-system
spec:
mergeGateways: true
Deploy merged-gateways example
Deploy resources on your cluster from the example.
kubectl apply -f https://raw.githubusercontent.com/envoyproxy/gateway/latest/examples/kubernetes/merged-gateways.yaml
Verify that Gateways are deployed and programmed
kubectl get gateways -n default
NAMESPACE NAME CLASS ADDRESS PROGRAMMED AGE

There should be also one deployment (envoy-merged-eg-668ac7ae-775f9865d-55zhs) for every Gateway and its name should reference the name of the GatewayClass.

Testing the Configuration
Get the name of the merged gateways Envoy service:
export ENVOY_SERVICE=$(kubectl get svc -n envoy-gateway-system --selector=gateway.envoyproxy.io/owning-gatewayclass=merged-eg -o jsonpath='{.items[0].metadata.name}')
Fetch external IP of the service:

In certain environments, the load balancer may be exposed using a hostname, instead of an IP address. If so, replace
ip
in the above command with hostname
.
