Keep application old version running side-by-side with the newer version in Azure Service Fabric

Question

I need to keep several versions of a application running at the same time on Service Fabric.

1.0 1.1 ....

Instead of updating and replacing versions, I need to k

Answer 1

As Matt Thalman said, is possible to have different versions of same app running in the Service Fabric cluster.

I've tested with the sample app WordCount(http://aka.ms/servicefabric-wordcountapp). To see more details how download the app and deploy it, see https://azure.microsoft.com/en-us/documentation/articles/service-fabric-get-started-with-a-local-cluster/

I've duplicated the WordCount as WordCountV1 and WordCountV2.

Then I've changed the /ApplicationManifest.xml to have different ApplicationTypeVersion on each package. It's necessary for displaying the current version of the App in the Cluster Manager because both apps are shown grouped by the ApplicationTypeName.

V1

V2

Yet I've changed the /WordCountWebServicePkg/Code/wwwroot/index.html file to have different content on both packages.

Is necessary to specify different Endpoints, so I've changed the file /WordCountWebServicePkg/ServiceManifest.xml in both packages to respond on different Ports

The last step is to use different a ApplicationName to publish packages:

V1

Publish-NewServiceFabricApplication -ApplicationPackagePath c:\ServiceFabric\WordCountV1.sfpkg -App
licationName "fabric:/WordCountV1"

V2

Publish-NewServiceFabricApplication -ApplicationPackagePath c:\ServiceFabric\WordCountV2.sfpkg -App
licationName "fabric:/WordCountV2"

Both apps are published side-by-side and we can have more control on version update with that.

V1

http://localhost:8081/

V2

http://localhost:8082/

Hope it helps!
