Unable to publish app to azure service fabric

Question

I am getting below error in visual studio after I run the app. I have even uninstalled/installed the azure service fabric cluster SDK, but it is of no use. I even reset the service fabric cluster

    New-ServiceFabricApplication : One or more placement constraints on the service are undefined on all nodes that are 
    currently up.

Answer 1

Firstly you need to understand that there is a difference between local/test environment and production environment.

Local/Test Environment => represents local cluster installed on your machine.

Production Environment => represents the cluster deployed on the cloud servers.

There are both types of nodes (Frontend and Backend nodes) available on the cloud environment, but this is not the case with the local environment.

So, while running your application locally or while deploying on cloud, check the placement constraints.

Refer to this blog which will help you understand the concept much better.
