I am new at camunda.
I am using the open source version.
I have created a simple bpmn model which i am trying to deploy but when i go to deployments, i cannot see the button to add a new model and allows me to browse for the the new model i just created,
The screen shot below is from the introduction session which is using the entreprise edition.
The deployment feature in Cockpit is enterprise only, for more information have a look at the Webapps docs - Deployment View | docs.camunda.org.
You can use the Rest API to deploy processes or deploy a single process via the Modeler.
