User story: When user creates a web application (app type : war), he should be able to select the runtime on which he wants his application to be deployed.
Application Creation: Steps: 1. A user navigates to ‘Create Application’ page. 2. Selects the application type as Web Application (app type = war). 3. Appfactory would populate a drop down list that displays the available runtimes: WSO2 Application Server v 5.1.0 Apache Tomcat v 7.0.54 4. User selects ‘Apache Tomcat’ as his preferred runtime and creates the application (Appfactory will record this information for later use). Application Deployment: 1. Upon the very first deployment of any application version onto a particular stage, Appfactory would make a subscription in Stratos, based on the selected runtime during the application creation (git repository containing the war artifact is provided during the subscription). Examples: a) A trunk version of the application is auto-built and auto-deployed onto the ‘Development’ stage. Before the very first deployment happens (after the auto build) Appfactory should make the subscription. b) Promotion of an application - A developer promotes a particular version of an application from the Development stage to the Testing stage. - A QA Engineer clicks on the ‘Deploy’ button of that version. - Appfactory checks whether there is a subscription available for this application in Testing stage. - If there is no such subscription already, then Appfactory would make a new subscription based on the runtime selected during the application creation. - Appfactory would deploy the particular application version onto the server in the Test Stage. 2. If the runtime selected by the user is based on a single tenanted cartridge, Stratos will spin up a new cartridge once a subscription is made. If the runtime provided is a multi-tenanted cartridge, the instances are created when cartridge definition is provisioned (as specified by the autoscaling and deployment policy). Improvements: User could be given the option to select the runtime per application per stage.
