Using MinIO instead of a S3 bucket

Since MinIO is an object storage server that implements the same public API as Amazon S3, can it be used to store terraform's state?

DynamoDB table for state locking and consistency checking on terraform

2 min read

When using a remote terraform state with S3, it is recomended to use a dynamoDB table for:

• State locking: Ensures the terrafrom state it is not being modified by two threads at the same time
• Consistency checking: Makes sure that that terraform it's being used it is the one that it is expected to be used

For example:

terraform {
  backend "s3" {
    bucket         = "infra-tfstate"
    key            = "jenkins/terraform.tfstate"
    region         = "eu-west-1"
    dynamodb_table = "terraform_locks"
  }
}

Unlocking remote terraform state

When you are working with the terraform state on a S3 bucket if you cancel an operation you might end up with the lock not being released so you won't be able to perform any more changes (not even plan a new change!)

Terraform acquires a state lock to protect the state from being written
by multiple users at the same time. Please resolve the issue above and try
again. For most commands, you can disable locking with the "-lock=false"
flag, but this is not recommended.
