terraform init fails with incompatible provider version constraints, or plan produces unexpected changes after an update. Here's how to read the constraint error and pin versions correctly across a team.
HashiCorp moved Terraform to the Business Source License on August 10, 2023; within six weeks, a community fork called OpenTF (soon renamed OpenTofu) had gathered 33,000 GitHub stars and joined the Linux Foundation.
Why Terraform's state file is the actual source of truth behind every plan and apply, and how drift, locking, and idempotency all follow from that design.
terraform plan or apply hangs, then fails with 'Error acquiring the state lock.' Here's how to confirm it's genuinely stale before force-unlocking it.
