The customizer supports both Linux and Windows. Next the resource to create and a set of properties. Instead, the parameter value from the earlier deployment is automatically reused in the rollback deployment. No separate build will be run to generate and then validate a customized image. In Bicep, use the dateTimeFromEpoch function. The next example uses the epoch time value to set the expiration for a key in a key vault. In Bicep, use the resourceId function. Now equipped with the knowledge of how Bicep variables work, we can discuss reference and list* functions. In this article we'll go over the sections of the files, so you can build your own.
