Stuck State Lock#

A CI job was cancelled, a laptop lost network, or a process crashed mid-apply. Terraform refuses to run:

Error acquiring the state lock
Lock Info:
  ID:        f8e7d6c5-b4a3-2109-8765-43210fedcba9
  Operation: OperationTypeApply
  Who:       deploy@ci-runner
  Created:   2026-02-20 09:15:22 +0000 UTC

Verify the lock holder is truly dead. Check CI job status, then:

terraform force-unlock f8e7d6c5-b4a3-2109-8765-43210fedcba9

If the lock was from a crashed apply, the state may be partially updated. Run terraform plan immediately after unlocking to see the current situation.

Infrastructure Disaster Recovery with Terraform#

Application disaster recovery is well-understood: replicate data, failover traffic, restore from backups. Infrastructure disaster recovery is different — you are recovering the platform that applications run on. If your Terraform state is lost, your VPC is deleted, or an entire region goes down, how do you rebuild?

This article covers the DR patterns specific to Terraform-managed infrastructure: protecting state, recovering from state loss, designing infrastructure for regional failover, and the runbooks that agents and operators need when things go wrong.
