Lock your Terraform state manually.
Terraform has a state lock mechanism and it works automatically. Nevertheless, I found it's useful to lock state manually when I don't want team members to touch code during refactorings of Terraform configurations.
Terraform has the terraform force-unlock command for when somthing goes wrong, and it doesn't provide the terraform lock command. It seems that this decision was by design. Not all backend types can acquire explicit lock. For more details, see hashicorp/terraform#17203
But I want terraform lock command!
- Lock your Terraform state manually.
That's all.
I'm testing in Terraform 0.12 + backend type s3 (lock with dynamodb). Other backend types may or may not work.
Required: Go 1.13+.
