Gotchas & Pitfalls

Suggested Topics

• Forgetting firewall rules: Azure Postgres blocks all connections by default
• Using admin credentials in application code instead of least-privilege users
• Choosing the wrong region: latency and cost differences between Azure regions
• Leaving resources running: forgotten Container Apps and databases generate ongoing costs
• Connection string errors: mixing up SSL modes, ports, or database names
• ADLS naming mistakes: spaces, special characters, or inconsistent date partition formats
• ACR authentication from Container Apps: forgetting to grant the Container App's managed identity AcrPull permissions, resulting in "image pull failed" errors
• Container App revision not updating: deploying a new image but the old revision still serves traffic; need to create a new revision or force update
• Container startup failures due to missing environment variables: container exits immediately with no obvious error
• Postgres SSL requirement: Azure Postgres enforces SSL by default; connection strings without sslmode=require will fail
• The mental shift from local .env file to Container Apps environment variable injection
• Forgetting to grant Key Vault access policy or RBAC role to the Managed Identity: the container starts but fails to read secrets
• Log Analytics query delay: logs can take 2-5 minutes to appear, which confuses students expecting real-time output
• Managed Identity not available locally: your local dev environment still needs connection strings or az login token; Managed Identity only works when deployed to Azure
