Install with Helm
3 minute read
Helm is a package manager for Kubernetes that automates the release and management of software on Kubernetes.
Envoy Gateway can be installed via a Helm chart with a few simple steps, depending on if you are deploying for the first time, upgrading Envoy Gateway from an existing installation, or migrating from Envoy Gateway.
Before you begin
Compatibility Matrix
Refer to the Version Compatibility Matrix to learn more.The Envoy Gateway Helm chart is hosted by DockerHub.
It is published at oci://docker.io/envoyproxy/gateway-helm
.
Note
We use v0.0.0-latest
as the latest development version.
You can visit Envoy Gateway Helm Chart for more releases.
Install with Helm
Envoy Gateway is typically deployed to Kubernetes from the command line. If you don’t have Kubernetes, you should use kind
to create one.
Developer Guide
Refer to the Developer Guide to learn more.Install the Gateway API CRDs and Envoy Gateway:
helm install eg oci://docker.io/envoyproxy/gateway-helm --version v0.0.0-latest -n envoy-gateway-system --create-namespace
Wait for Envoy Gateway to become available:
kubectl wait --timeout=5m -n envoy-gateway-system deployment/envoy-gateway --for=condition=Available
Install the GatewayClass, Gateway, HTTPRoute and example app:
kubectl apply -f https://github.com/envoyproxy/gateway/releases/download/latest/quickstart.yaml -n default
Note: quickstart.yaml
defines that Envoy Gateway will listen for
traffic on port 80 on its globally-routable IP address, to make it easy to use
browsers to test Envoy Gateway. When Envoy Gateway sees that its Listener is
using a privileged port (<1024), it will map this internally to an
unprivileged port, so that Envoy Gateway doesn’t need additional privileges.
It’s important to be aware of this mapping, since you may need to take it into
consideration when debugging.
Helm chart customizations
Some of the quick ways of using the helm install command for envoy gateway installation are below.
Helm Chart Values
If you want to know all the available fields inside the values.yaml file, please see the Helm Chart Values.Increase the replicas
helm install eg oci://docker.io/envoyproxy/gateway-helm --version v0.0.0-latest -n envoy-gateway-system --create-namespace --set deployment.replicas=2
Change the kubernetesClusterDomain name
If you have installed your cluster with different domain name you can use below command.
helm install eg oci://docker.io/envoyproxy/gateway-helm --version v0.0.0-latest -n envoy-gateway-system --create-namespace --set kubernetesClusterDomain=<domain name>
Note: Above are some of the ways we can directly use for customization of our installation. But if you are looking for more complex changes values.yaml comes to rescue.
Using values.yaml file for complex installation
deployment:
envoyGateway:
resources:
limits:
cpu: 700m
memory: 128Mi
requests:
cpu: 10m
memory: 64Mi
ports:
- name: grpc
port: 18005
targetPort: 18000
- name: ratelimit
port: 18006
targetPort: 18001
config:
envoyGateway:
logging:
level:
default: debug
Here we have made three changes to our values.yaml file. Increase the resources limit for cpu to 700m
, changed the port for grpc to 18005
and for ratelimit to 18006
and also updated the logging level to debug
.
You can use the below command to install the envoy gateway using values.yaml file.
helm install eg oci://docker.io/envoyproxy/gateway-helm --version v0.0.0-latest -n envoy-gateway-system --create-namespace -f values.yaml
