From 42fe58c5e3246bbefb14ca222901044bffa69125 Mon Sep 17 00:00:00 2001 From: adamrtalbot <12817534+adamrtalbot@users.noreply.github.com> Date: Thu, 14 Aug 2025 13:04:54 +0100 Subject: [PATCH 1/2] feat(azure): add managed identity support for resource file downloads in Azure Batch Previously, Azure Batch required SAS tokens to download and upload the resource files (.command.sh and .command.run). This PR adds support for using managed identities to download these files. We use the managed identity specified in the Azure Batch configuration where available, if it's not found it falls back to using a SAS token. - Add getPoolManagedIdentityResourceId() method to retrieve managed identity from pool - Modify resourceFileUrls() to use managed identity authentication when available - Support 'auto' mode to use first available identity or specific client ID - Fall back to SAS token authentication when managed identity is not available This allows Azure Batch tasks to download resource files using pool-assigned managed identities instead of SAS tokens, improving security and eliminating the need to manage token expiration.
