Camunda Platform 8

This repository contains links to Camunda Platform 8 resources, the official release artifacts (binaries), and supporting config files for running Docker Compose as a local development option.

⚠️ Docker Compose is only recommended for local development. ⚠️

We recommend using SaaS or Helm/Kubernetes for development.

For more information about Self-Managed, including additional development installation options, see our documentation.

For production setups we recommend using Helm charts which can be found at helm.camunda.io.

Using docker compose

ℹ️ The docker-compose file in this repository uses the latest compose specification, which was introduced with docker compose version 1.27.0+. Please make sure to use an up-to-date docker compose version.

ℹ️ Docker 20.10.16+ is required.

To spin up a complete Camunda Platform 8 Self-Managed environment locally the docker-compose.yaml file in this repository can be used.

The full environment contains these components:

Zeebe
Operate
Tasklist
Connectors
Optimize
Identity
Elasticsearch
Keycloak
PostgreSQL

ℹ️ Web Modeler is not included by default. Please follow the instructions below to install it.

Clone this repo and issue the following command to start your environment:

docker compose up -d

Wait a few minutes for the environment to start up and settle down. Monitor the logs, especially the Keycloak container log, to ensure the components have started.

Now you can navigate to the different web apps and log in with the user demo and password demo:

Keycloak is used to manage users. Here you can log in with the user admin and password admin

Keycloak: http://localhost:18080/auth/

The workflow engine Zeebe is available using gRPC at localhost:26500.

To tear down the whole environment run the following command:

docker compose down -v

Zeebe, Operate, Tasklist, along with Optimize require a separate network from Identity as you'll see in the docker-compose file.

Using the basic components

If Optimize, Identity, and Keycloak are not needed you can use the docker-compose-core.yaml instead which does not include these components:

docker compose -f docker-compose-core.yaml up -d

Deploying BPMN diagrams

In addition to the local environment setup with docker compose, use the Camunda Desktop Modeler to locally model BPMN diagrams for execution and directly deploy them to your local environment. As an enterprise customer, you can use Web Modeler.

Feedback and updates are welcome!

Securing the Zeebe API

By default, the Zeebe GRPC API is publicly accessible without requiring any client credentials for development purposes.

You can however enable authentication of GRPC requests in Zeebe by setting the environment variable ZEEBE_AUTHENTICATION_MODE to identity, e.g. via running:

ZEEBE_AUTHENTICATION_MODE=identity docker compose up -d

or by modifying the default value in the .env file.

Connectors

Both docker-compose files contain our out-of-the-box Connectors.

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

To inject secrets into the Connector runtime they can be added to the connector-secrets.txt file inside the repository in the format NAME=VALUE per line. The secrets will then be available in the Connector runtime with the format secrets.NAME.

To add custom Connectors either create a new docker image bundling them as described here.

Alternatively, you can mount new Connector JARs as volumes into the /opt/app folder by adding this to the docker-compose file. Keep in mind that the Connector JARs need to bring along all necessary dependencies inside the JAR.

Kibana

A kibana profile is available in the provided docker compose files to support inspection and exploration of the Camunda Platform 8 data in Elasticsearch. It can be enabled by adding --profile kibana to your docker compose command. In addition to the other components, this profile spins up Kibana. Kibana can be used to explore the records exported by Zeebe into Elasticsearch, or to discover the data in Elasticsearch used by the other components (e.g. Operate).

You can navigate to the Kibana web app and start exploring the data without login credentials:

Kibana: http://localhost:5601

Note You need to configure the index patterns in Kibana before you can explore the data.

Go to Management > Stack Management > Kibana > Index Patterns.

Create a new index pattern. For example, zeebe-record-* matches the exported records.

If you don't see any indexes then make sure to export some data first (e.g. deploy a process). The indexes of the records are created when the first record of this type is exported.

Go to Analytics > Discover and select the index pattern.

Desktop Modeler

ℹ️ The Desktop Modeler is open source, free to use.

Download the Desktop Modeler and start modeling BPMN, DMN and Camunda Forms on your local machine.

Deploy or execute a process

Without authentication

Once you are ready to deploy or execute processes use these settings to deploy to the local Zeebe instance:

Authentication: None
URL: http://localhost:26500

With Zeebe request authentication

If you enabled authentication for GRPC requests on Zeebe you need to provide client credentials when deploying and executing processes:

Authentication: OAuth
URL: http://localhost:26500
Client ID: zeebe
Client secret: zecret
OAuth URL: http://localhost:18080/auth/realms/camunda-platform/protocol/openid-connect/token
Audience: zeebe-api

Web Modeler Self-Managed

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

The Docker images for Web Modeler are available in a private registry. Enterprise customers either already have credentials to this registry, or they can request access to this registry through their CSM contact at Camunda.

To run Camunda Platform with Web Modeler Self-Managed clone this repo and issue the following commands:

$ docker login registry.camunda.cloud
Username: your_username
Password: ******
Login Succeeded
$ docker compose -f docker-compose.yaml -f docker-compose-web-modeler.yaml up -d

To tear down the whole environment run the following command

$ docker compose -f docker-compose.yaml -f docker-compose-web-modeler.yaml down -v

If you want to delete everything (including any data you created). Alternatively, if you want to keep the data run:

$ docker compose -f docker-compose.yaml -f docker-compose-web-modeler.yaml down

Login

You can access Web Modeler Self-Managed and log in with the user demo and password demo at http://localhost:8070.

Deploy or execute a process

Without authentication

Once you are ready to deploy or execute processes use these settings to deploy to the local Zeebe instance:

Authentication: None
URL: http://zeebe:26500

With Zeebe request authentication

If you enabled authentication for GRPC requests on Zeebe you need to provide client credentials when deploying and executing processes:

Authentication: OAuth
URL: http://zeebe:26500
Client ID: zeebe
Client secret: zecret
OAuth URL: http://keycloak:8080/auth/realms/camunda-platform/protocol/openid-connect/token
Audience: zeebe-api

Emails

The setup includes Mailpit as a test SMTP server. It captures all emails sent by Web Modeler, but does not forward them to the actual recipients.

You can access emails in Mailpit's Web UI at http://localhost:8075.

Troubleshooting

Submitting Issues

When submitting an issue on this repository, please make sure your issue is related to the docker compose deployment method of the Camunda Platform. All questions regarding to functionality of the web applications should be instead posted on the Camunda Forum. This is the best way for users to query for existing answers that others have already encountered. We also have a category on that forum specifically for Deployment Related Topics.

Running on arm64 based hardware

When using arm64-based hardware like a M1 or M2 Mac the Keycloak container might not start because Bitnami only provides amd64-based images for versions < 22. You can build and tag an arm-based image locally using the following command. After building and tagging the image you can start the environment as described in Using docker-compose.

$ DOCKER_BUILDKIT=0 docker build -t bitnami/keycloak:19.0.3 "https://github.com/camunda/camunda-platform.git#8.2.15:.keycloak/"

Resource based authorizations

You can control access to specific processes and decision tables in Operate and Tasklist with resource based authorization.

This feature is disabled by default and can be enabled by setting RESOURCE_AUTHORIZATIONS_ENABLED to true, either via the .env file or through the command line:

RESOURCE_AUTHORIZATIONS_ENABLED=true docker compose up -d

Multi-Tenancy

You can use multi-tenancy to achieve tenant-based isolation.

This feature is disabled by default and can be enabled by setting MULTI_TENANCY_ENABLED to true, either via the .env file or through the command line:

ZEEBE_AUTHENICATION_MODE=identity MULTI_TENANCY_ENABLED=true docker compose up -d

As seen above the feature also requires you to use identity as an authentication provider.

Ensure you setup tenants in identity after you started the platform.
