VSTS "Deploy Compose Application to Service Fabric" to an agent with SF SDK 2.8 or 3.0 fails

I use Deploy Compose Application to Service Fabric to deploy containers with VSTS on Service Fabric . My build agent had Service Fabric SDK 2.7. As soon as I upgrade it to 2.8 or 3.0, the VSTS task breaks with

The ServiceDnsName for DefaultService 'xxx' is invalid

Solution

  • I cloned vsts-tasks, debugged ServiceFabricCompose and found out that UI parameter Application Name is placed into New-ServiceFabricComposeDeployment -DeploymentName.

    For old SDK 2.7 we had "fabric:/XYZ" in Application Name.

    This format is not valid for SDK 2.8 + 3.0.

    Changing to Application Name to "XYZ" solved the problem.
