Constraining Jobs

Here are a few examples of common job constraints which may be helpful when using Nomad IIS.

Run a .NET (Core) App​

Running a .NET App on IIS requires the node to have the .NET Core Hosting Bundle installed. The following constraint will ensure that the job is only placed on nodes, having this bundle installed.

constraint {
  attribute = "${attr.driver.iis.iis_aspnet_core_available}"
  value     = true
}
tip

For running .NET Core Apps on IIS it is also suggested to set managed_runtime_version to None in the task configuration.

Using the URL-Rewrite Module​

The URL-Rewrite Module also needs to be installed separately by downloading from here. The following constraint will ensure that the job is only placed on nodes, having this module installed.

constraint {
  attribute = "${attr.driver.iis.iis_rewrite_module_available}"
  value     = true
}
