D3E installation guide

Diagrid Dapr Distribution for Enterprise (D3E) provides security-enhanced Dapr binaries with enterprise features for multi-tenancy, namespace isolation, and reduced permission sets. Choose the installation option that best fits your security and operational requirements.

Choose your installation path

1. Single namespace isolation

Dapr control plane scoped to one namespace. Simplest setup for single-team deployments.

2. Multi-namespace isolation

Dapr control plane scoped to multiple namespaces. Ideal for multi-team environments with shared infrastructure.

3. Multiple Dapr Installations

Deploy multiple isolated Dapr control planes in one cluster. Best for complete tenant separation.

4. CRD-Free Installation

Install without CRDs/ClusterRoles using the Diagrid Dapr Injector Helm chart. Maximum security, higher operational overhead.

Access details

D3E is packaged as a Helm chart and comes with custom container images for the Dapr control plane and sidecars. All deployment resources are published on Diagrid's public artifact repository.

Helm chart

• Public gallery: gallery.ecr.aws/diagrid
• Chart URL: public.ecr.aws/diagrid/d3e-charts/d3e-dapr

Container images

The following images are public and can be pulled without an image-pull secret:

• public.ecr.aws/diagrid/d3e/daprd
• public.ecr.aws/diagrid/d3e/operator
• public.ecr.aws/diagrid/d3e/placement
• public.ecr.aws/diagrid/d3e/scheduler
• public.ecr.aws/diagrid/d3e/injector
• public.ecr.aws/diagrid/d3e/sentry

D3E license JWT

A signed D3E license JWT (diagrid.token) is required for D3E installation. This license key is issued by Diagrid when your contract is activated and should be stored securely (e.g., in a secrets manager).

The license JWT encodes your customer name, a unique license ID, and an expiration date. All D3E control plane components validate the license signature at startup using an embedded public key — no network call is required.

License lifecycle:

• Active: Components start normally without warnings.
• Expiring soon: Within 6 months of token expiry, a warning is printed at startup. It is recommended at this time to begin your contract renewal process with Diagrid.
• Grace period: Between 0 - 90 days after contract end, components continue running but print a prominent warning on startup. Contact your support representative immediately to retrieve your new key once Diagrid contract renewal has completed.
• Expired + grace period elapsed: 90+ days after expiry components refuse to start. A new license is required.

To renew your license, contact support@diagrid.io or your Diagrid account team.

Installation Setup

Follow these steps to prepare your cluster for D3E installation:

1. 1
   Remove an existing Dapr installation from your cluster to avoid conflicts:

   helm uninstall dapr -n dapr-system
   kubectl delete pvc -n dapr-system --all
   kubectl delete crds subscriptions.dapr.io resiliencies.dapr.io \
     configurations.dapr.io components.dapr.io httpendpoints.dapr.io

2. 2
   Set your D3E license JWT in your terminal:export D3E_LICENSE=<LICENSE-JWT-PROVIDED-BY-DIAGRID>
3. 3
   Choose your installation option below based on your security and operational requirements.

---

Option 1: Single namespace isolation

Option 1: Single namespace isolation

Best for: Single-team deployments where all Dapr applications run in one namespace.

In this configuration, the Dapr control plane is scoped to a single namespace. Only applications deployed within that namespace can be injected with Dapr sidecars.

Configuration

Helm value	Description	Default	Options
global.rbac.namespaced	Enable namespace isolation	false	true, false

Installation

The following command installs D3E version 1.17.0-d3e.1 into the dapr-system namespace, allowing only applications in dapr-system to use Dapr:

helm install \
  --create-namespace \
  -n dapr-system dapr \
  --set global.rbac.namespaced=true \
  --set diagrid.token=${token} \
  --set global.tag=1.17.0-d3e.1 \
  oci://public.ecr.aws/diagrid/d3e-charts/d3e-dapr --version 1.17.0-d3e.1

---

Option 2: Multi-namespace isolation

Option 2: Multi-namespace isolation

Best for: Multi-team environments where teams share Kubernetes infrastructure and some namespaces but need isolated Dapr access.

The Dapr control plane is scoped to a list of namespaces. Only applications in those namespaces can be injected with Dapr sidecars.

Configuration

Helm value	Description	Default	Options
global.rbac.namespaced	Enable namespace isolation	false	true, false
global.rbac.namespaces	List of namespaces Dapr can inject into	[]	["ns-1", "ns-2"]

Installation

The following command installs D3E version 1.17.0-d3e.1 into the dapr-system namespace and allows applications in the crud-app namespace to use Dapr:

helm install \
  --create-namespace \
  -n dapr-system \
  --set global.rbac.namespaced=true \
  --set-json 'global.rbac.namespaces=["crud-app"]' \
  --set diagrid.token=${token} \
  --set global.tag=1.17.0-d3e.1 \
  dapr oci://public.ecr.aws/diagrid/d3e-charts/d3e-dapr --version 1.17.0-d3e.1

Add More Namespaces

To allow more namespaces, extend the JSON array: 'global.rbac.namespaces=["crud-app", "order-app", "payment-app"]'

---

Option 3: Multiple Dapr installations

Option 3: Multiple Dapr installations

Best for: Complete tenant separation where teams need fully isolated Dapr control planes.

Deploy multiple Dapr control planes in the same cluster. Each installation is isolated to its own namespace(s), providing complete separation between apps.

Installation

The following commands install D3E version 1.17.0-d3e.1 twice in the same cluster:

First installation: dapr-system control plane namespace serving application namespace crud-app:

helm install \
  --create-namespace \
  -n dapr-system \
  --set global.rbac.namespaced=true \
  --set-json 'global.rbac.namespaces=["crud-app"]' \
  --set diagrid.token=${token} \
  --set global.tag=1.17.0-d3e.1 \
  dapr oci://public.ecr.aws/diagrid/d3e-charts/d3e-dapr --version 1.17.0-d3e.1

Second installation: dapr-secondary control plane namespace serving application namespace order-app:

helm install \
  --create-namespace \
  -n dapr-secondary \
  --set global.rbac.namespaced=true \
  --set-json 'global.rbac.namespaces=["order-app"]' \
  --set diagrid.token=${token} \
  --set global.tag=1.17.0-d3e.1 \
  dapr-secondary oci://public.ecr.aws/diagrid/d3e-charts/d3e-dapr --version 1.17.0-d3e.1

---

Option 4: ClusterRole & CRD free installation

Option 4: ClusterRole & CRD free installation

Best for: Environments with strict security requirements that prohibit CRDs and ClusterRoles.

This configuration eliminates CustomResourceDefinitions (CRDs) and Kubernetes ClusterRoles by deploying Dapr in standalone mode without the standard sidecar injector control plane service. Instead, the Diagrid Dapr Injector Helm library is used as a dependency on your applications to inject sidecars directly into application manifests.

High Operational Overhead

This option requires significant operational overhead. You must configure Dapr sidecars in your application manifests and manage Dapr resources within your application Helm charts. Only use this option if you have strict requirements against CRDs and ClusterRoles.

Configuration

All standard Helm values from Options 1-3 are supported, plus:

Helm value	Description	Default	Options
dapr_sidecar_injector.enabled	Deploy standard sidecar injector	true	true, false
global.rbac.injector.enabled	Deploy injector ClusterRole	true	true, false
global.rbac.crds.enabled	Enable CRDs RBAC	true	true, false
global.rbac.operator.enabled	Enable operator RBAC	true	true, false

Installation

The following installation command installs D3E version 1.17.0-d3e.1 without CRDs or ClusterRoles:

helm install \
  --skip-crds \
  -n <namespace> \
  --set global.tag=1.17.0-d3e.1 \
  --set global.actors.enabled=false \
  --set global.scheduler.enabled=false \
  --set global.rbac.injector.enabled=false \
  --set global.rbac.createTokenReviewerRole=false \
  --set global.rbac.createTokenReviewerRoleBinding=false \
  --set global.rbac.crds.enabled=false \
  --set global.rbac.operator.enabled=false \
  --set global.rbac.namespaced=true \
  --set global.rbac.sentry.serviceAccount.create=true \
  --set-json 'global.rbac.namespaces=["<namespace_A>","<namespace_B>"]' \
  --set dapr_operator.enabled=false \
  --set dapr_sidecar_injector.enabled=false \
  --set dapr_placement.mode=standalone \
  --set dapr_scheduler.mode=standalone \
  --set dapr_sentry.mode=standalone \
  --set dapr_sentry.injectDaprSystemConfig=true \
  --set dapr_config.dapr_config_chart_included=false \
  --set diagrid.token="${token}" \
  dapr oci://public.ecr.aws/diagrid/d3e-charts/d3e-dapr --version 1.17.0-d3e.1

Configure your applications

After installing D3E, configure your applications to use the Diagrid Dapr Injector:

1. 1
   Add the Diagrid Dapr Injector Helm library chart as a dependency to your application's Helm chart.
2. 2
   Test the behavior using the sample application to understand the changes that need to be made.
3. 3
   Configure all Dapr-enabled applications with the injector Helm settings to ensure sidecars are injected.
