COS

Kind: Standard (with locking)

Stores the state as an object in a configurable prefix in a given bucket on Tencent Cloud Object Storage (COS). This backend also supports state locking.

~> Warning! It is highly recommended that you enable Object Versioning on the COS bucket to allow for state recovery in the case of accidental deletions and human error.

Example Configuration

terraform {
  backend "cos" {
    region = "ap-guangzhou"
    bucket = "bucket-for-terraform-state-1258798060"
    prefix = "terraform/state"
  }
}

This assumes we have a COS Bucket created named bucket-for-terraform-state-1258798060, Terraform state will be written into the file terraform/state/terraform.tfstate.

Data Source Configuration

To make use of the COS remote state in another configuration, use the terraform_remote_state data source.

data "terraform_remote_state" "foo" {
  backend = "cos"

  config = {
    region = "ap-guangzhou"
    bucket = "bucket-for-terraform-state-1258798060"
    prefix = "terraform/state"
  }
}

Configuration variables

The following configuration options or environment variables are supported:

• secret_id - (Optional) Secret id of Tencent Cloud. It supports environment variables TENCENTCLOUD_SECRET_ID.
• secret_key - (Optional) Secret key of Tencent Cloud. It supports environment variables TENCENTCLOUD_SECRET_KEY.
• region - (Optional) The region of the COS bucket. It supports environment variables TENCENTCLOUD_REGION.
• bucket - (Required) The name of the COS bucket. You shall manually create it first.
• prefix - (Optional) The directory for saving the state file in bucket. Default to "env:".
• key - (Optional) The path for saving the state file in bucket. Defaults to terraform.tfstate.
• encrypt - (Optional) Whether to enable server side encryption of the state file. If it is true, COS will use 'AES256' encryption algorithm to encrypt state file.
• acl - (Optional) Object ACL to be applied to the state file, allows private and public-read. Defaults to private.
