Amazon Managed Service for Apache Flink application lifecycle management with Terraform

This article explains how to use Terraform to automate Apache Flink application lifecycle management on Amazon Managed Service for Apache Flink, covering deployment, updates, scaling, and troubleshooting.

• Terraform provides version control, consistency, and CI/CD integration for Flink applications
• S3 backend with state locking prevents concurrent execution conflicts
• Running Terraform in Docker ensures consistent, portable environment without local installation
• Supported operations: create/start apps, deploy code changes, scale parallelism, upgrade Flink versions
• State compatibility required for code updates; AllowNonRestoredState enables operator removal
• System rollback feature automatically reverts incompatible changes when enabled
• Unsupported operations: start/stop without config change, restart from older snapshot, manual rollbacks
• Terraform auto-refreshes state after manual rollbacks via AWS CLI or Console

Terraform streamlines Flink application lifecycle management but requires AWS CLI for certain operations like standalone start/stop and manual rollbacks.
