Mastering Remote Backends in Terraform for CI/CD

Practitioner — Hands-on experience recommended

Remote backends in Terraform exist to solve the challenges of state management and execution in a collaborative environment. They enable both storage of state snapshots and execution of operations, making them unique among Terraform backends. This is particularly beneficial in CI/CD pipelines where multiple team members need to work on infrastructure changes simultaneously without stepping on each other's toes.

When you configure a remote backend, you specify parameters like hostname, organization, and workspaces. For instance, the hostname defaults to app.terraform.io, which is where your Terraform Cloud instance lives. The workspaces block allows you to choose between a single workspace or multiple similarly-named workspaces, giving you flexibility in how you manage your environments. With full remote operations, commands like terraform plan and terraform apply run in Terraform Cloud's environment, streaming logs back to your local terminal. This setup uses variable values from the associated HCP Terraform workspace, ensuring consistency across your deployments.

In production, remember to use environment variables for sensitive data instead of hardcoding credentials directly in your configuration. This practice prevents sensitive information from leaking into your .terraform directory or plan files. Also, avoid including the token in your configuration; instead, authenticate using terraform login. Be cautious with the terraform.workspace variable in versions 1.0.x or earlier, as it can lead to issues with remote operations. Finally, note that the remote backend was introduced in Terraform v0.11.13, and as of v1.1.0, it's recommended to leverage HCP Terraform's built-in cloud integration for better performance and features.

Key takeaways

→Configure the remote backend with `hostname` set to `app.terraform.io` for Terraform Cloud.
→Use the `workspaces` block to manage single or multiple remote workspaces effectively.
→Authenticate using `terraform login` instead of hardcoding tokens in your configuration.
→Stream logs to your local terminal during remote operations for better visibility.
→Avoid using `terraform.workspace` in Terraform 1.0.x or earlier to prevent operational issues.

Why it matters

Using remote backends in Terraform enhances collaboration and efficiency in CI/CD workflows. It ensures that state management is centralized and operations are executed in a controlled environment, reducing the risk of conflicts and errors.

Code examples

HCL

1# Using a single workspace:
2terraform {
3  backend "remote" {
4    hostname = "app.terraform.io"
5    organization = "company"
6    workspaces {
7      name = "my-app-prod"
8    }
9  }
10}
11
12# Using multiple workspaces:
13terraform {
14  backend "remote" {
15    hostname = "app.terraform.io"
16    organization = "company"
17    workspaces {
18      prefix = "my-app-"
19    }
20  }
21}

HCL

# main.tf
terraform {
  required_version = "~> 0.12.0"
  backend "remote" {}
}

HCL

1# config.remote.tf
2backend "remote" {
3  workspaces {
4    name = "workspace"
5  }
6  hostname = "app.terraform.io"
7  organization = "company"
8}

When NOT to use this

We do not recommend using `terraform.workspace` in Terraform configurations that use Terraform 1.0.x or earlier and run remote operations against HCP Terraform workspaces.
