Hi Folks, I’m experimenting with open source flowable 6.5 on my local machine running docker-compose. It is working great but when I try to publish my app in the modeler I receive the following error: Error calling deploy endpoint: Connect to localhost:8080 [localhost/127.0.0.1] failed: Connection refused (Connection refused) I think this might have something to do with my docker setup insofar as the localhost configuration is concerned. here is the section I think the problem is.. Does anyone have experience with this type of thing? `` # -------------------------------------- # Flowable IDM (Identity Management) # -------------------------------------- flowable-idm: image: flowable/flowable-idm container\_name: flowable\_idm platform: linux/amd64 depends\_on: - postgres environment: SPRING\_DATASOURCE\_DRIVERCLASSNAME: org.postgresql.Driver SPRING\_DATASOURCE\_URL: jdbc:postgresql://postgres:5432/flowable SPRING\_DATASOURCE\_USERNAME: flowable SPRING\_DATASOURCE\_PASSWORD: flowable ports: - “8080:8080” networks: - appnet # -------------------------------------- # Flowable BPM Engine + REST API # --------------------------------------` flowable-rest: image: flowable/flowable-rest container\_name: flowable\_rest platform: linux/amd64 depends\_on: - postgres - flowable-idm environment: SPRING\_DATASOURCE\_DRIVERCLASSNAME: org.postgresql.Driver SPRING\_DATASOURCE\_URL: jdbc:postgresql://postgres:5432/flowable SPRING\_DATASOURCE\_USERNAME: flowable SPRING\_DATASOURCE\_PASSWORD: flowable ports: - “8081:8080” networks: - appnet # -------------------------------------- # Flowable Modeler # -------------------------------------- flowable-modeler: image: flowable/flowable-modeler container\_name: flowable\_modeler platform: linux/amd64 depends\_on: - postgres - flowable-idm environment: SPRING\_DATASOURCE\_DRIVERCLASSNAME: org.postgresql.Driver SPRING\_DATASOURCE\_URL: jdbc:postgresql://postgres:5432/flowable SPRING\_DATASOURCE\_USERNAME: flowable SPRING\_DATASOURCE\_PASSWORD: flowable ```` # REQUIRED for IDM integration — these must be EXACT FLOWABLE_MODELER_IDM_URL: ```http://flowable-idm:8080/flowable-idm`` FLOWABLE_COMMON_APP_IDM_URL: ``http://flowable-idm:8080/flowable-idm`` FLOWABLE_COMMON_APP_IDM_REDIRECT_URL: ``http://localhost:8082/flowable-modeler`` FLOWABLE_IDM_APP_ADMIN_USER_ID: admin FLOWABLE_IDM_APP_ADMIN_PASSWORD: test ```` ports: - “8082:8888” networks: - appnet` ---

Hi Frank, I would expect some property where to publish your app from modeler to runtime. That’s why default values were used. Regards Martin ---

Thank you, I was actually able to get past the original error but now I get the following: **flowable\_modeler |** 2025-12-08 11:00:08.975 ERROR 1 — [nio-8888-exec-8] o.f.u.m.s.AppDefinitionPublishService : Invalid deploy result code: HTTP/1.1 404 [http://flowable-rest:8080/flowable-rest/repository/app-repository/deployments?deploymentKey=insolvencyApp&deploymentName=Insolvency+App](http://flowable-rest:8080/flowable-rest/repository/app-repository/deployments?deploymentKey=insolvencyApp&deploymentName=Insolvency+App) for url So i’ve upgraded from a “connection refused” to a “404” error. ChatGPT is telling me that publishing apps through the Open Source version of flowable is actually disabled. This cant be right can it? ---

I fixed my issue. It appears that when utilizing docker, I needed to establish the entire flowable all-in-one package. Here is the full docker-compose.yaml file for anyone else who runs into this issue: ```auto services: -------------------------------------- Database -------------------------------------- postgres: image: postgres:15 container_name: db_postgres environment: POSTGRES_USER: flowable POSTGRES_PASSWORD: flowable POSTGRES_DB: flowable ports: - “5432:5432” volumes: - postgres_data:/var/lib/postgresql/data networks: - appnet -------------------------------------- Flowable ALL-IN-ONE (Modeler + IDM + REST + Task + Admin) -------------------------------------- flowable-all: image: flowable/all-in-one:latest container_name: flowable_all platform: linux/amd64 depends_on: - postgres environment: SPRING_DATASOURCE_DRIVERCLASSNAME: org.postgresql.Driver SPRING_DATASOURCE_URL: jdbc:postgresql://postgres:5432/flowable SPRING_DATASOURCE_USERNAME: flowable SPRING_DATASOURCE_PASSWORD: flowable # Optional: enable dev-friendly mode (hot reload) FLOWABLE_COMMON_APP_IDM_ADMIN_USER: admin FLOWABLE_COMMON_APP_IDM_ADMIN_PASSWORD: test ports: - "8080:8080" # All Flowable UI apps networks: - appnet -------------------------------------- Node.js backend API -------------------------------------- backend: build: ./backend-api container_name: node_api command: npm run dev volumes: - ./backend-api:/usr/src/app - /usr/src/app/node_modules ports: - “4000:4000” environment: - PORT=4000 - DB_HOST=postgres - DB_USER=flowable - DB_PASS=flowable - DB_NAME=flowable # REST API now lives inside flowable-all-in-one - FLOWABLE_REST_URL=http://flowable_all:8080/flowable-rest - FLOWABLE_USERNAME=admin - FLOWABLE_PASSWORD=test depends_on: - postgres - flowable-all networks: - appnet -------------------------------------- React frontend -------------------------------------- frontend: build: ./frontend container_name: react_frontend command: npm start volumes: - ./frontend:/usr/src/app - /usr/src/app/node_modules ports: - “3000:3000” environment: - CI=false - REACT_APP_API_URL=http://node_api:4000 networks: - appnet -------------------------------------- Volumes -------------------------------------- volumes: postgres_data: -------------------------------------- Network -------------------------------------- networks: appnet: driver: bridge ```
