⚠️ Important Notice: Upcoming changes to the Bitnami Catalog

Beginning August 28th, 2025, Bitnami will evolve its public catalog to offer a curated set of hardened, security-focused images under the new Bitnami Secure Images initiative. As part of this transition:

• Granting community users access for the first time to security-optimized versions of popular container images.
• Bitnami will begin deprecating support for non-hardened, Debian-based software images in its free tier and will gradually remove non-latest tags from the public catalog. As a result, community users will have access to a reduced number of hardened images. These images are published only under the “latest” tag and are intended for development purposes
• Starting August 28th, over two weeks, all existing container images, including older or versioned tags (e.g., 2.50.0, 10.6), will be migrated from the public catalog (docker.io/bitnami) to the “Bitnami Legacy” repository (docker.io/bitnamilegacy), where they will no longer receive updates.
• For production workloads and long-term support, users are encouraged to adopt Bitnami Secure Images, which include hardened containers, smaller attack surfaces, CVE transparency (via VEX/KEV), SBOMs, and enterprise support.

These changes aim to improve the security posture of all Bitnami users by promoting best practices for software supply chain integrity and up-to-date deployments. For more details, visit the Bitnami Secure Images announcement.

Introduction

This chart bootstraps a Envoy Gateway deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

• Kubernetes 1.23+
• Helm 3.8.0+

Installing the Chart

To install the chart with the release name my-release:

helm install my-release REGISTRY_NAME/REPOSITORY_NAME/envoy-gateway

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts.

The command deploys Envoy Gateway on the Kubernetes cluster in the default configuration. The Parameters section lists the parameters that can be configured during installation.

Tip

: List all releases using helm list

Configuration and installation details

Operator configuration

The Bitnami Envoy Gateway chart allows configuring the operator using ConfigMaps. This is done using the overrideConfiguration parameter, which merges the provided settings with the default configuration. In the example below we add extra configuration parameters to the operator:

overrideConfiguration:
  admin:
    enableDumpConfig: false

It is also possible to use an existing ConfigMap using the existingConfigMap parameter (note that this is not compatible with the overrideConfiguration parameter).

Certificate Generation Job

The chart provides a certificate generation job, which uses the Envoy Operator certgen command provide to create all the necessary TLS secrets. This is enabled by setting certgen.enabled=true and all the Job settings can be configured under the certgen section.

Resource requests and limits

Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the resources value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.

To make this process easier, the chart contains the resourcesPreset values, which automatically sets the resources section according to different presets. Check these presets in the bitnami/common chart. However, in production workloads using resourcesPreset is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the official Kubernetes documentation.

Prometheus metrics

This chart can be integrated with Prometheus by setting metrics.enabled to true. This will expose the envoy-gateway native Prometheus endpoint in both the container and service. It will have the necessary annotations to be automatically scraped by Prometheus.

Prometheus requirements

It is necessary to have a working installation of Prometheus or Prometheus Operator for the integration to work. Install the Bitnami Prometheus helm chart or the Bitnami Kube Prometheus helm chart to easily have a working Prometheus in your cluster.

Integration with Prometheus Operator

The chart can deploy ServiceMonitor objects for integration with Prometheus Operator installations. To do so, set the value metrics.serviceMonitor.enabled=true. Ensure that the Prometheus Operator CustomResourceDefinitions are installed in the cluster or it will fail with the following error:

no matches for kind "ServiceMonitor" in version "monitoring.coreos.com/v1"

Install the Bitnami Kube Prometheus helm chart for having the necessary CRDs and the Prometheus Operator.

Rolling VS Immutable tags

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

Additional environment variables

In case you want to add extra environment variables (useful for advanced operations like custom init scripts), you can use the extraEnvVars property:

extraEnvVars:
  - name: LOG_LEVEL
    value: error

Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the extraEnvVarsCM or the extraEnvVarsSecret values inside the operator, apiserver and cluster sections.

Sidecars

If additional containers are needed in the same pod as envoy-gateway (such as additional metrics or logging exporters), they can be defined using the sidecars parameter:

sidecars:
- name: your-image-name
  image: your-image
  imagePullPolicy: Always
  ports:
  - name: portname
    containerPort: 1234

If these sidecars export extra ports, extra port definitions can be added using the service.extraPorts parameter (where available), as shown in the example below:

service:
  extraPorts:
  - name: extraPort
    port: 11311
    targetPort: 11311

If additional init containers are needed in the same pod, they can be defined using the initContainers parameter. Here is an example:

initContainers:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
        containerPort: 1234

Learn more about sidecar containers and init containers.

Deploying extra resources

Apart from the Operator, you may want to deploy Gateway, HTTPRoutes or other operator objects. For covering this case, the chart allows adding the full specification of other objects using the extraDeploy parameter. The following example deploys a GatewayClasse, a Gateway, HTTPRoutes and a service (adapted from the upstream quickstart documentation):

extraDeploy:
- apiVersion: gateway.networking.k8s.io/v1
  kind: GatewayClass
  metadata:
    name: eg

        containers:
          - image: bitnami/nginx
            imagePullPolicy: Always
            name: backend
            ports:
              - containerPort: 8080
- apiVersion: gateway.networking.k8s.io/v1
  kind: HTTPRoute
  metadata:
    name: backend
  spec:
    parentRefs:
      - name: eg
    hostnames:
      - "www.example.com"
    rules:
      - backendRefs:
          - group: ""
            kind: Service
            name: backend
            port: 80
            weight: 1
        matches:
          - path:
              type: PathPrefix
              value: /

Check the Envoy Gateway official documentation for the list of available objects.

Pod affinity

This chart allows you to set your custom affinity using the affinity parameter. Find more information about Pod affinity in the kubernetes documentation.

As an alternative, use one of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the bitnami/common chart. To do so, set the podAffinityPreset, podAntiAffinityPreset, or nodeAffinityPreset parameters.

The above parameters map to the env variables defined in bitnami/envoy-gateway. For more information please refer to the bitnami/envoy-gateway image documentation.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

helm install my-release \
  --set metrics.enabled=true \
    REGISTRY_NAME/REPOSITORY_NAME/envoy-gateway

The above command enables metrics scraping with Prometheus.

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

helm install my-release -f values.yaml REGISTRY_NAME/REPOSITORY_NAME/envoy-gateway

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts. Tip: You can use the default values.yaml
