How to deploy a Camunda modeled diagram into Camunda Tomcat

I am trying to set up a BPMN workflow with Camunda. For this, I already made a diagram using the Camunda modeler. Now I want to open this BPMN diagram in Camunda. Camunda's Tomcat is installed and running, but I can't manage to upload/ find the diagram in Camunda's Tomcat. I am currently trying this on my local machine.

Anyone who knows how to get a BPMN diagram into Camunda's Tomcat?

Deploy Camunda Process:-

https://docs.camunda.org/get-started/quick-start/deploy/

For local deployment from modeler to tomcat

Rest endpoint to deploy http://yourhost:yourport/rest(or /engine-rest)

you can also use the play button to deploy if you are deploying the process for the first time.

camunda-spring-boot-starter is configured to use the SpringProcessEngineConfiguration auto deployment feature by default.

https://docs.camunda.org/manual/7.9/user-guide/spring-boot-integration/process-applications/

a) You can deploy directly from the modeler to the server. https://docs.camunda.org/get-started/quick-start/deploy/ In the latest release the feature has improved further: https://blog.camunda.com/post/2019/10/camunda-modeler-3.4.0-released/

enter image description here On a local setup use rest endpoint http://localhost:8080/engine-rest if using on of the prepacked distributions or http://localhost:8080/rest if using Spring boot.

b) Process and decisions models (bpmn, dmn) can be auto-deployed. For instance placing the files into the src/main/resources folder (on a default Spring boot setup) will auto-deploy during startup.

c) There are other auto-deploy configuration options: https://docs.camunda.org/manual/latest/user-guide/spring-framework-integration/deployment/

d) You can use the REST-API, for instance with Postman to deploy. https://docs.camunda.org/manual/latest/reference/rest/deployment/post-deployment/

In addition to the ways to deploy described by @MuffinMICHI you can also deploy your diagram via the REST API. You just make POST request to /engine-rest/deployment/create You set Content-Type to: 

application/x-www-form-urlencoded

You set these parameters:

 deployment-name: <SOME NAME>
 deployment-source: <SOME NAME>
 data: <UPLOAD THE DIAGRAM HERE>
 diagram (optional): <UPLOAD IMAGE FOR DIAGRAM>

There are two ways how you can upload your diagram to your BPMN engine.

  1. In the Camunda Modeler, there is a little upwards-pointing arrow in the menu bar. There you can specify where your engine is running and upload the diagram directly from the modeler.

    https://docs.camunda.org/get-started/quick-start/service-task/

  2. If you also have some JavaDelegate-classes you want to deploy with your diagram, you can pack all these things in a WAR-file and put it in the webapps-folder of your Tomcat which will then automatically deploy your file.

    https://docs.camunda.org/get-started/java-process-app/service-task/

The provided links guide you to the official Camunda documentation where all these things are explained in detail.
