Azure IaC Pipeline Patterns

Authentication — Workload Identity Federation (OIDC)

Use OIDC/Workload Identity Federation everywhere — no stored client secrets.

GitHub Actions Setup

# One-time setup: configure the federated credential
azd pipeline config   # automatically configures OIDC for GitHub Actions

Required secrets in GitHub:

• AZURE_CLIENT_ID — App Registration client ID
• AZURE_TENANT_ID — Azure AD tenant ID
• AZURE_SUBSCRIPTION_ID — target subscription

Azure DevOps Setup

Use a service connection with Workload Identity Federation:

Project Settings → Service connections → New → Azure Resource Manager → Workload Identity Federation
