## What you need to know

Can Azure PowerShell consume a remote .bicepparam file through TemplateParameterUri?

## Potentially affected

Azure PowerShell deployments using Bicep templates and parameter files.

## DSE recommendation

DSE recommends documenting each deployment input's format and location before changing its delivery path.

## Article

## Source facts

Azure PowerShell’s TemplateParameterUri accepts JSON parameter files, not .bicepparam files. A Bicep parameter file must be local. Remote Bicep template deployment is also unsupported directly; Microsoft documents building it to a JSON template before placing that template at a remote location. These restrictions concern the file formats being consumed, not merely whether a URL can be opened. [Microsoft Learn](https://learn.microsoft.com/en-us/azure/azure-resource-manager/bicep/deploy-powershell).

## Applicability

Use this review when a deployment moves inputs from a workstation to hosted artifacts. Classify the template and parameter file separately. Keep the expected local Bicep inputs distinct from remotely retrieved JSON, and review the documented tool versions before adopting the chosen path.

## DSE recommendation

DSE recommends documenting each deployment input’s format and location before changing its delivery path. If the workflow requires remote parameters, produce and review the supported JSON artifact rather than renaming a Bicep parameter file or changing only a command switch. Preserve its association with the source revision and expected parameter values. Keep sensitive values out of broadly accessible artifact locations.

## Verification

Rehearse the exact deployment command in a controlled environment and confirm which template and parameter artifacts it consumes. Inspect the resulting resource configuration against the approved input values. Test failures with harmless files so the team can distinguish an unsupported format from an authorization or retrieval problem. Record the accepted format and location in the runbook instead of assuming all parameter-file extensions are interchangeable.
