Camunda 8 Helm installation

We recommend using Kubernetes and Helm to deploy and run Camunda 8 Self-Managed in production.

There are many ways you can provision and configure a Kubernetes cluster, and there are a number of architectural choices you need to make. Will your workers run in the Kubernetes cluster or external to it? You will need to configure your Kubernetes cluster and modify this to suit the architecture you are building.

Camunda provides continuously improved Helm charts, of which are not cloud provider-specific so you can choose your Kubernetes provider. The charts are available in the Camunda Helm repository and we encourage you to report issues.

What is Helm?

Helm is a package manager for Kubernetes resources. Helm allows us to install a set of components by simply referencing a package name and allowing us to override configurations to accommodate these packages to different scenarios.

Helm also provides dependency management between charts, meaning that charts can depend on other charts. This allows us to aggregate a set of components installed with a single command.

For more details, check the full list of Helm values.


The following charts will be installed as part of Camunda 8 Self-Managed:

  • Zeebe: Deploys a Zeebe Cluster with three brokers using the camunda/zeebe Docker image.
  • Zeebe Gateway: Deploys the standalone Zeebe Gateway with two replicas.
  • Operate: Deploys Operate, which connects to an existing Elasticsearch.
  • Tasklist: Deploys the Tasklist component to work with user tasks.
  • Optimize: Deploys the Optimize component to analyze the historic process executions.
  • Identity: Deploys the Identity component responsible for authentication and authorization.
  • Connectors: Deploys the Connectors component responsible for inbound and outbound integration with external systems.
  • Elasticsearch: Deploys an Elasticsearch cluster with two nodes.
  • Console: Deploys Camunda Console Self-Managed.
    • Note: The chart is disabled by default and needs to be enabled explicitly as the Console is only available to enterprise customers.
  • Web Modeler: Deploys the Web Modeler component that allows you to model BPMN processes in a collaborative way.
    • Note: The chart is disabled by default and needs to be enabled explicitly as Web Modeler is only available to enterprise customers.
Amazon OpenSearch Service Helm support

The existing Helm charts use the Elasticsearch configurations by default. The Helm charts can still be used to connect to Amazon OpenSearch Service. Refer to using Amazon OpenSearch Service.

Zeebe: Configure the OpenSearch exporter.

Operate & Tasklist: These components use the same parameters for both Elasticsearch and OpenSearch. Replace the elasticsearch part of the relevant configuration key with opensearch, together with its appropriate value.


Refer to the Operate and Tasklist configuration documentation for additional component configuration parameters to update.

Camunda 8 Self-Managed Architecture Diagram

When installing the camunda-platform Helm chart, all components shown on the architectural diagram above are installed.


Starting from the Camunda v8.4 (January 2024), the Camunda 8 Helm chart version is decoupled from the version of the application (e.g., the chart version is 9.0.0 and the application version is 8.4.x).

For more details about the applications version included in the Helm chart, review the full version matrix.


At, you'll find a Helm chart to configure a 3-broker cluster with:

  • Two Elasticsearch instances
  • Operate
  • Two Zeebe Gateways
  • Tasklist

This size is comparable with the Production-S cluster plan in Camunda 8 SaaS. It should be sufficient for 80% of use cases.


Before deploying Camunda using Helm, you need the following:

  • Kubernetes cluster: either local, cloud platform, or on-premises.
  • Helm.
  • Kubectl CLI.

Helm repository

You have to add the Camunda Helm chart repository to use the charts. Once this is done, Helm can fetch and install charts hosted at

helm repo add camunda
helm repo update

Once this is completed, we will be ready to install the Helm chart hosted in the official Camunda Helm chart repo.

Install Camunda Helm chart

To install the available Camunda 8 components inside a Kubernetes cluster, you can simply run:

helm install camunda camunda/camunda-platform

You can also add the -n flag to specify in which Kubernetes namespace the components should be installed.

The command does not install Web Modeler or Console by default. To enable Web Modeler, refer to the installation instructions below. To enable Console, refer to the installation instructions.

Installing all the components in a cluster requires all Docker images to be downloaded to the Kubernetes cluster. Depending on which cloud provider you are using, the time it will take to fetch all the images will vary.

For air-gapped environments, refer to installing in an air-gapped environment.

Review the progress of your deployment by checking if the Kubernetes pods are up and running with the following:

kubectl get pods

This will return something similar to the following:

NAME                                           READY   STATUS              RESTARTS   AGE

elasticsearch-master-0 0/1 Pending 0 4s
elasticsearch-master-1 0/1 Init:0/1 0 4s

Wait for all Kubernetes pods to reach the Ready state. For example:

NAME                                           READY    STATUS    RESTARTS   AGE
elasticsearch-master-0 1/1 Running 0 4m6s

camunda-zeebe-0 1/1 Running 0 4m6s
camunda-tasklist-XXX 1/1 Running 0 4m6s
camunda-zeebe-gateway 1/1 Running 0 4m6s

Install the latest Camunda 8 version

When you use the Camunda 8 Helm chart, it automatically selects the latest version of Camunda 8 applications. However, there might be slight discrepancies between the versions of the chart and its applications/dependencies, as they are released separately.

To ensure you're installing the most current version of both the chart and its applications/dependencies, use the following command:

# This will install the latest Camunda Helm chart with the latest applications/dependencies.
helm install camunda camunda/camunda-platform \

If you want to install a previous version of the Camunda componenets, follow this command structure:

# This will install Camunda Helm chart v8.1.x with the latest applications/dependencies of v8.1.x.
helm install camunda camunda/camunda-platform --version 8.1 \

Accessing Camunda services

By default, Camunda services deployed in a cluster are not accessible from outside the cluster. However, you can choose from several methods to connect to these services:

  • Port forwarding: This method allows you to direct traffic from your local machine to the cluster, making it possible to access Camunda services directly. For detailed instructions, refer to accessing components without Ingress.
  • Ingress configuration: You can set up the NGINX Ingress controller to manage external service access. This can be done by combining components Ingress in a single domain or configuring separate Ingress for each component. For detailed instructions, refer to combined and separated Ingress setup.
  • EKS cluster installation: For those deploying Camunda 8 on an Amazon EKS cluster, refer to installing Camunda 8 on an EKS cluster.

Configuring Enterprise components and Connectors

Enterprise components secret

Enterprise components such as Console and Web Modeler are published in Camunda's private Docker registry ( and are exclusive to enterprise customers. These components are not available in public repositories.

To enable Kubernetes to pull the images from this registry, first create an image pull secret using the credentials you received from Camunda:

kubectl create secret docker-registry registry-camunda-cloud \
--namespace=<NAMESPACE> \ \
--docker-username=<DOCKER_USER> \
--docker-password=<DOCKER_PASSWORD> \

Use registry-camunda-cloud as a secret after replacing <DOCKER_USER>, <DOCKER_PASSWORD>, and <DOCKER_EMAIL> with your credentials.

The secret must be created in the same Kubernetes namespace where you'll install the Helm chart. Replace <NAMESPACE> to set the namespace.

Alternatively, create an image pull secret from your Docker configuration file.

Install Connectors

The Connector runtime comes enabled by default. To start using Connectors, install Connector element templates. Learn more in our documentation for Web Modeler or Desktop Modeler.

Find all available configurable options at the official Camunda Helm values docs.

Disable Connectors

To disable Connectors, pass the connectors.enabled: false value when deploying Camunda Helm Chart.

Polling authentication mode

Connectors use the Operate API to fetch process definitions containing inbound Connectors. Depending on your Camunda architecture, you may want to choose one of the following values for the inbound.mode:

  • disabled - Polling from Operate is disabled. Connector runtime will support only outbound interactions, such as HTTP REST calls.
  • credentials - Connector runtime will attempt to authenticate to the Operate API with password-based basic HTTP authentication.
  • oauth - (Recommended and enabled by default) the Connector runtime will attempt to authenticate to the Operate API with an OAuth 2.0 provider. Camunda offers Keycloak as a default OAuth provider.

For more details, check Connectors Helm values.

Install Web Modeler


Web Modeler Self-Managed is available to Enterprise customers only.

Follow the steps below to install the Camunda Helm chart with Web Modeler enabled:

Configure Web Modeler

To set up Web Modeler, you need to provide the following required configuration values (all available configuration options are described in more detail in the Helm chart's values docs):

  • Enable Web Modeler with webModeler.enabled: true (it is disabled by default).
  • Configure the previously created image pull secret in webModeler.image.pullSecrets.
  • Configure your SMTP server by providing the values under webModeler.restapi.mail.
    • Web Modeler requires an SMTP server to send notification emails to users.
  • Configure the database connection
    • Web Modeler requires a PostgreSQL database as persistent data storage (other database systems are currently not supported).
    • Option 1: Set postgresql.enabled: true. This will install a new PostgreSQL instance as part of the Helm release (using the PostgreSQL Helm chart by Bitnami as a dependency).
    • Option 2: Set postgresql.enabled: false and configure a connection to an external database.

We recommend specifying these values in a YAML file that you pass to the helm install command. A minimum configuration file would look as follows:

enabled: true
# Create the secret as mentioned according to the instructions.
- name: registry-camunda-cloud
smtpPort: 587
smtpUser: user
smtpPassword: secret
# Email address to be displayed as sender of emails from Web Modeler
enabled: true

If you don't want to install a new PostgreSQL instance with Helm, but connect Web Modeler to an existing external database, set postgresql.enabled: false and provide the values under webModeler.restapi.externalDatabase:

url: jdbc:postgresql://
user: modeler-user
password: secret
# disables the PostgreSQL chart dependency
enabled: false

For more details, check Web Modeler Helm values.

Install Console

Console Self-Managed is an Enterprise component, which means it is disabled by default in the Camunda 8 Helm chart since it requires an Enterprise license to access the Camunda container registry.

To install Console, two steps are required:

  1. Create a secret with Camunda registry credentials.
  2. Enable Console, and reference the created Kubernetes secret object via Helm values.
enabled: true
- name: registry-camunda-cloud

For more details, check Console Helm values.


Console Self-Managed requires the Identity component to authenticate. Camunda Helm Chart installs Identity by default. When logging in to Console when using port-forward, port-forward Keycloak service kubectl port-forward svc/<RELEASE-NAME>-keycloak 18080:80 or configure Identity with Ingress as described in combined and separated Ingress setup.

Installation troubleshooting

Check that each pod is running and ready. If one or more of your pods are still pending, it means it cannot be scheduled onto a node. Usually, this happens because there are insufficient resources that prevent it. Use the kubectl describe ... command to check on messages from the scheduler:

kubectl describe pods <POD_NAME>

If the output of the describe command was not helpful, tail the logs of these pods by running the following:

kubectl logs -f <POD_NAME>


For upgrading the Camunda Helm chart from one release to another, perform a Helm upgrade.

General notes

  • Zeebe gateway is deployed as a stateless service. We support Kubernetes startup and liveness probes for Zeebe.
  • Zeebe broker nodes need to be deployed as a StatefulSet to preserve the identity of cluster nodes. StatefulSets require persistent storage, which must be allocated in advance. Depending on your cloud provider, the persistent storage differs as it is provider-specific.
