Camunda 8.7 self managed docker compose with standalone gateway and broker problem
02:55 23 Dec 2025

I have tried a lot for building and running a Camunda 8.7 self managed docker compose with just a standalone gateway and a standalone broker with one partition. Following is my latest try:

# While the Docker images themselves are supported for production usage,
# this docker-compose.yaml is designed to be used by developers to run
# an environment locally. It is not designed to be used in production.
# We recommend to use Kubernetes in production with our Helm Charts:
# https://docs.camunda.io/docs/self-managed/setup/install/
# For local development, we recommend using KIND instead of `docker-compose`:
# https://docs.camunda.io/docs/self-managed/platform-deployment/helm-kubernetes/guides/local-kubernetes-cluster/

# This is a full configuration with Zeebe Gateway, 3 Zeebe Brokers, Operate, Tasklist, Optimize, Identity, Keycloak, Elasticsearch and Web Modeler.

#version: '3.8'
