justinrush e65e55e2dd lib/backup: add support for Azure Managed Identity (#6518) ... ### Describe Your Changes These changes support using Azure Managed Identity for the `vmbackup` utility. It adds two new environment variables: * `AZURE_USE_DEFAULT_CREDENTIAL`: Instructs the `vmbackup` utility to build a connection using the [Azure Default Credential](https://pkg.go.dev/github.com/Azure/azure-sdk-for-go/sdk/azidentity@v1.5.2#NewDefaultAzureCredential) mode. This causes the Azure SDK to check for a variety of environment variables to try and make a connection. By default, it tries to use managed identity if that is set up. This will close https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5984 ### Checklist The following checks are **mandatory**: - [x] My change adheres [VictoriaMetrics contributing guidelines](https://docs.victoriametrics.com/contributing/). ### Testing However you normally test the `vmbackup` utility using Azure Blob should continue to work without any changes. The set up for that is environment specific and not listed out here. Once regression testing has been done you can set up [Azure Managed Identity](https://learn.microsoft.com/en-us/entra/identity/managed-identities-azure-resources/overview) so your resource (AKS, VM, etc), can use that credential method. Once it is set up, update your environment variables according to the updated documentation. I added unit tests to the `FS.Init` function, then made my changes, then updated the unit tests to capture the new branches. I tested this in our environment, but with SAS token auth and managed identity and it works as expected. --------- Signed-off-by: Zakhar Bessarab <z.bessarab@victoriametrics.com> Co-authored-by: Justin Rush <jarush@epic.com> Co-authored-by: Zakhar Bessarab <z.bessarab@victoriametrics.com> Co-authored-by: hagen1778 <roman@victoriametrics.com> (cherry picked from commit 5fd3aef549)		2024-07-10 12:26:21 +02:00
