To assign a Key Vault Reader role to a managed identity, follow these steps:
1. Navigate to Azure Key Vault: Go to the Azure portal and find your Key Vault instance.
2. Access Control (IAM): Click on the Access control (IAM) tab from the Key Vault settings menu.
3. Add Role Assignment: Select Add and then choose Add role assignment to open the role assignment page.
4. Select Role: On the Roles tab, search for and select the Key Vault Reader role. This role allows the managed identity to list key vault objects.
5. Select Members: Go to the Members tab, select Managed identity, and then click + Select members.
6. Choose Managed Identity: In the Managed identity dropdown, select either System-assigned managed identity or User-assigned managed identity, depending on your setup. Then, choose the specific managed identity you want to assign the role to.
7. Assign Role: Click Select and then Review + assign to add the role assignment. You may need to click Review + assign a second time to confirm.
8. Verify Role Assignment: After assigning the role, verify that the managed identity has been successfully granted the Key Vault Reader role by checking the role assignments list in the IAM section of your Key Vault.
Additionally, ensure that any necessary access policies are configured in the Key Vault to allow the managed identity to access secrets or other resources as needed[5][10].
