Deployment To Heroku
This tutorial describes how to deploy a Camunda application to Heroku PaaS platform from a GitHub repository.
In this step, we are going to the deploy the digibp-camunda-template based project to Heroku PaaS using a GitHub repository. The contents of the digibp-camunda-template are explained here.
If haven't already registered to the Heroku PaaS, you have to do so first. Then you can create a new App as shown here (use a different name, possibly the name of your group). This step should be performed by only one member of the team. Other members can access the App as collaborators.
Then switch to deploy, use the GitHub deployment method, and you may have to authorise Heroku to access your GitHub account (only applies for the first time):
Search for the GitHub repository of your group and connect it (only applies for the first time):
Finally, you can press the button Deploy Branch to trigger the deployment process:
You may want to have a look at the current Logs, which you can find under more:
After the state changed from starting to up, you can open the app by using the button open app. You should see the Camunda login view:
Based on the default configuration, the admin username is demo, and the password is as well demo.
The team members can be added as collaborators. This enables the team to access the same deployment on Heroku.
Click on the Access or Manage Access links as highlighted in the figure:
Enter the email id of your team members (the one used for Heroku registration):
This section describes the remote testing method on the Heroku PaaS using the Camunda modeller. With this method you can test BPMN, DMN and CMMN files. To identify any issues in the execution of the models, you have to consult the logs on Heroku.
Please note that this Camunda Modeler feature is available from version 1.12.0+
You can deploy BPMN, DMN and CMMN diagrams directly from the modeler.
First, you must have a configured deployment endpoint - preferably to the Heroku instantiation:
Then you can deploy the current diagram by clicking the deploy icon in the menu bar and choose Deploy Current Diagram:
If you receive a 500 error message, you may have to consult the server logs locally or on Heroku.
Save your models under src\main\resources\modelling and push them to GitHub repository after ensuring it works as expected.
