Docker

This page guides you through Camunda 8 Docker images and how to run the platform in a developer setup using Docker Compose.

Docker images

We provide Docker images via Dockerhub. All these images are publicly accessible (except for Web Modeler).

info

The provided Docker images are supported for production usage only on Linux systems. Windows or macOS are only supported for development environments.

Component	Docker image	Link to configuration options
Zeebe	camunda/zeebe:latest	Environment variables
Operate	camunda/operate:latest	Operate configuration
Tasklist	camunda/tasklist:latest	Tasklist configuration
Identity	camunda/identity:latest	Configuration variables
Optimize	camunda/optimize:8-latest	Environment variables
Connectors	camunda/connectors:latest	Connectors configuration
Connectors Bundle	camunda/connectors-bundle:latest	Connectors configuration

Zeebe is the only component that is often run on its own as a standalone component. In this scenario, it does not need anything else, so a simple docker run is sufficient:

docker run --name zeebe -p 26500-26502:26500-26502 camunda/zeebe:latest

This will give you a single broker node with the following ports exposed:

• 26500: Gateway API (this is the port clients need to use)
• 26501: Command API (internal, gateway-to-broker)
• 26502: Internal API (internal, broker-to-broker)

Multi-platform support

With the Camunda 8.2.0 release and onward, all Camunda 8 Docker images are provided as multi-platform images natively supporting the following platforms:

• linux/amd64
• linux/arm64

Your Docker client should automatically pull the image that suits your platform. We currently only recommend the linux/amd64 for production usage, as the linux/arm64 image is provided mainly for development purposes.

note

For Web Modeler, we only provide multi-platform images from the following releases onward: 8.2.8, 8.3.1, 8.4.0-alpha1.

Web Modeler

note

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

The Docker images for Web Modeler are not publicly accessible, but available to enterprise customers only from Camunda's private Docker registry.

Web Modeler Component	Docker image
Backend (restapi)	registry.camunda.cloud/web-modeler-ee/modeler-restapi:latest
Frontend (webapp)	registry.camunda.cloud/web-modeler-ee/modeler-webapp:latest
WebSocket server	registry.camunda.cloud/web-modeler-ee/modeler-websockets:latest

To pull the images you first need to log in using the credentials you received from Camunda:

$ docker login registry.camunda.cloud
Username: your_username
Password: ******
Login Succeeded

See the instructions below on how to use the Web Modeler images with Docker Compose. You can also find more information on the supported configuration variables.

Docker Compose

A Docker Compose configuration to run Zeebe, Operate, Tasklist, Optimize, Identity, and Connectors Bundle is available in the camunda-platform repository. Follow the instructions in the README.

danger

While the Docker images themselves are supported for production usage, the Docker Compose files are designed to be used by developers to run an environment locally; they are not designed to be used in production. We recommend to use Kubernetes in production.

This Docker Compose configuration serves two purposes:

1. It can be used to start up a development environment locally.
2. It documents how the various components need to be wired together.

note

We recommend to use Helm + KIND instead of Docker Compose for local environments, as the Helm configurations are battle-tested and much closer to production systems.

Web Modeler

An additional Docker Compose configuration to run Web Modeler is also available in the camunda-platform repository. Follow the instructions in the README to utilize this configuration.

Configuration hints

Zeebe

Volumes

The default data volume is under /usr/local/zeebe/data. It contains all data which should be persisted.

Configuration

The Zeebe configuration is located at /usr/local/zeebe/config/application.yaml. The logging configuration is located at /usr/local/zeebe/config/log4j2.xml.

The configuration of the Docker image can also be changed using environment variables. The configuration template file also contains information on the environment variables to use for each configuration setting.

Available environment variables:

• ZEEBE_LOG_LEVEL - Sets the log level of the Zeebe Logger (default: info).
• ZEEBE_BROKER_NETWORK_HOST - Sets the host address to bind to instead of the IP of the container.
• ZEEBE_BROKER_CLUSTER_INITIALCONTACTPOINTS - Sets the contact points of other brokers in a cluster setup.

Optimize

Some configuration properties are optional and have default values. See a description of these properties and their default values in the table below:

Name	Description	Default value
SPRING_PROFILES_ACTIVE	Determines the mode Optimize is to be run in. For Self-Managed, set to ccsm.
CAMUNDA_OPTIMIZE_IDENTITY_ISSUER_URL	The URL at which Identity can be accessed by Optimize.
CAMUNDA_OPTIMIZE_IDENTITY_ISSUER_BACKEND_URL	The URL at which the Identity auth provider can be accessed by Optimize. This should match the configured provider in Identity and is to be used for container to container communication.
CAMUNDA_OPTIMIZE_IDENTITY_CLIENTID	The Client ID used to register Optimize with Identity.
CAMUNDA_OPTIMIZE_IDENTITY_CLIENTSECRET	The secret used when registering Optimize with Identity.
CAMUNDA_OPTIMIZE_IDENTITY_AUDIENCE	The audience used when registering Optimize with Identity.
OPTIMIZE_ELASTICSEARCH_HOST	The address/hostname under which the Elasticsearch node is available.	localhost
OPTIMIZE_ELASTICSEARCH_HTTP_PORT	The port number used by Elasticsearch to accept HTTP connections.	9200
CAMUNDA_OPTIMIZE_SECURITY_AUTH_COOKIE_SAME_SITE_ENABLED	Determines if same-site is enabled for Optimize cookies. This must be set to false.	true
CAMUNDA_OPTIMIZE_ELASTICSEARCH_SECURITY_USERNAME	The username for authentication in environments where a secured Elasticsearch connection is configured.
CAMUNDA_OPTIMIZE_ELASTICSEARCH_SECURITY_PASSWORD	The password for authentication in environments where a secured Elasticsearch connection is configured.
CAMUNDA_OPTIMIZE_ENTERPRISE	This should only be set to true if an Enterprise License has been acquired.	true
CAMUNDA_OPTIMIZE_ZEEBE_ENABLED	Enables import of Zeebe data in Optimize.	false
CAMUNDA_OPTIMIZE_ZEEBE_NAME	The record prefix for exported Zeebe records.	zeebe-record
CAMUNDA_OPTIMIZE_ZEEBE_PARTITION_COUNT	The number of partitions configured in Zeebe.	1
CAMUNDA_OPTIMIZE_SHARING_ENABLED	Enable/disable the possibility to share reports and dashboards.	true
SPRING_SECURITY_OAUTH2_RESOURCESERVER_JWT_JWK_SET_URI	Authentication for the Public REST API using a resource server to validate the JWT token. Complete URI to get public keys for JWT validation.	null
OPTIMIZE_API_ACCESS_TOKEN	Authentication for the Public REST API using a static shared token. Will be ignored if SPRING_SECURITY_OAUTH2_RESOURCESERVER_JWT_JWK_SET_URI is also set.	null
CAMUNDA_OPTIMIZE_CONTAINER_ENABLE_SNI_CHECK	Determines whether SNI checking should be enabled.	true

Like for example this docker-compose configuration:

optimize:
    container_name: optimize
    image: camunda/optimize:8-latest
    ports:
        - 8090:8090
    environment:
        - SPRING_PROFILES_ACTIVE=ccsm
        - CAMUNDA_OPTIMIZE_IDENTITY_ISSUER_URL=http://localhost:9090
        - CAMUNDA_OPTIMIZE_IDENTITY_ISSUER_BACKEND_URL=http://keycloak:8080/auth/realms/camunda-platform
        - CAMUNDA_OPTIMIZE_IDENTITY_CLIENTID=optimize
        - CAMUNDA_OPTIMIZE_IDENTITY_CLIENTSECRET=secret
        - CAMUNDA_OPTIMIZE_IDENTITY_AUDIENCE=optimize-api
        - OPTIMIZE_ELASTICSEARCH_HOST=localhost
        - OPTIMIZE_ELASTICSEARCH_HTTP_PORT=9200
        - CAMUNDA_OPTIMIZE_SECURITY_AUTH_COOKIE_SAME_SITE_ENABLED=false
        - CAMUNDA_OPTIMIZE_ENTERPRISE=false
        - CAMUNDA_OPTIMIZE_ZEEBE_ENABLED=true
        - CAMUNDA_OPTIMIZE_ZEEBE_NAME=zeebe-record
        - CAMUNDA_OPTIMIZE_ZEEBE_PARTITION_COUNT=1
        - CAMUNDA_OPTIMIZE_SHARING_ENABLED=true
        - SPRING_SECURITY_OAUTH2_RESOURCESERVER_JWT_JWK_SET_URI=https://weblogin.cloud.company.com/.well-known/jwks.json
        - OPTIMIZE_API_ACCESS_TOKEN=secret

Self-Managed Optimize must be able to connect to Elasticsearch to write and read data. In addition, Optimize needs to connect to Identity for authentication purposes. Both of these requirements can be configured with the options described above.

Optimize must also be configured as a client in Identity, and users will only be granted access to Optimize if they have a role that has write:* permission for Optimize.

For Optimize to import Zeebe data, Optimize must also be configured to be aware of the record prefix used when the records are exported to Elasticsearch. This can also be configured per the example above.

Connectors

Use the provided Docker Compose files to execute all out-of-the-box Connectors automatically. This uses the Connectors Bundle Docker image.

Note that some out-of-the-box Connectors are licensed under the Camunda Self-Managed Free Edition license. Find an overview in the Connectors Bundle project.

Refer to the Connector installation guide for details on how to provide the Connector templates for modeling.

Running single Connectors container

docker run --rm --name=MyConnectorsInstance \
  --network=camunda-platform_camunda-platform \
  -e ZEEBE_CLIENT_BROKER_GATEWAY-ADDRESS=zeebe:26500 \
  -e ZEEBE_CLIENT_SECURITY_PLAINTEXT=true \
  -e CAMUNDA_CONNECTOR_POLLING_ENABLED=false \
  -e CAMUNDA_CONNECTOR_WEBHOOK_ENABLED=false \
  -e OPERATE_CLIENT_ENABLED=false \
  -e SPRING_MAIN_WEB-APPLICATION-TYPE=none \
    camunda/connectors-bundle:latest

Custom set of Connectors

To add custom Connectors, you can build on top of our Connectors base image that includes the pre-packaged runtime environment without any Connector. To use the image, at least one Connector must be added to the classpath. We recommend providing JARs with all dependencies bundled.

caution

As all Connectors share a single classpath, different versions of the same dependency can be available and cause conflicts. To prevent this, common dependencies like jackson can be shaded and relocated inside the Connector's JAR.

You can add a Connector JAR by extending the base image with a JAR from a public URL:

FROM camunda/connectors:x.y.z

ADD https://repo1.maven.org/maven2/io/camunda/connector/connector-http-json/x.y.z/connector-http-json-0..0-with-dependencies.jar /opt/app/

You can also add a Connector JAR using volumes:

docker run --rm --name=connectors -d -v $PWD/connector.jar:/opt/app/ camunda/connectors:x.y.z
