Installation OMN Workflow

To be able to use OMN Workflow Engine (mandatory) the corresponding Docker image with Camunda and the workflow components must be installed.

Create file

/etc/docker-compose/wfl/docker-compose.yml

version: '3'
srvices:
    camunda:
        image: hub.apollon.de/omn/camunda:5.6.0
        ports:
            - 8080:8080
            - 8000:8000
        restart: always
        environment:
            DB_DRIVER: org.postgresql.Driver
            DB_URL: jdbc:postgresql://camunda-db:5432/camunda
            DB_USERNAME: camunda
            DB_PASSWORD: camunda
            WAIT_FOR: camunda-db:5432
    camunda-db:
        image: postgres:alpine
        ports:
            - 5432:5432
        environment:
            POSTGRES_USER: camunda
            POSTGRES_PASSWORD: camunda
            POSTGRES_DB: camunda
    wflcomponent:
        image: "hub.apollon.de/omn/workflow-component:5.5.0"
        ports:
            - 8083:8083
        volumes:
            - ./configfiles:/usr/share/wfl-cmoponent/config

Create file

/etc/docker-compose/configfiles/application.yml

Note: secret tokens must be replaced (eg. [SECRET_1])

logging:
    level:
        root: INFO
    server:
      port: 8083
spring:
    mvc:
    servlet:
        path: /wf/api/v1
    main:
        banner-mode: off

                key: *_[SECRET_2]_*

    host: http://192.168.42.42:8070
    api-base: /api/v1
    config-api-base: /api/config/v1

Add the following properties

Properties File Properties

jwt_filter.properties

api.secrets=\{ workflow: '[SECRET_2]' , frontend: '[SECRET_1]' }

jwt.expire.max=604800

The configuration files use the placeholders[SECRET_1] and[SECRET_2] to clarify which strings have to match, but can be replaced with any string.

Those secrets should be at least 256 bit(32 characters), better even 512 bit (64 characters) long Strings. A Simple way of generating such keys is hashing a random text using sha256 in a generic online tool.
Start the docker-compose:
```
docker-compose up -d
```

Properties File	Properties
jwt_filter.properties	api.secrets=\{ workflow: *'[SECRET_2]'* , frontend: *'[SECRET_1]'* } jwt.expire.max=604800
