🌐 Web query:
Is Terraform version 1.14.7 a valid release?
💡 Result:
Yes, Terraform version 1.14.7 is a valid official release. It was released on March 11, 2026, as confirmed by multiple authoritative sources including HashiCorp's official release page, GitHub releases, and changelog. Binaries are available at releases.hashicorp.com/terraform/1.14.7/, and it is listed among recent versions on the main releases index. The release notes mention bumping the Go version to 1.25.8 for security scanner fixes. Newer versions like 1.14.8 and 1.15.0 pre-releases exist as of April 2026, but 1.14.7 remains valid and supported.

🌐 Web query:
Does Terraform version constraint syntax support the v prefix like "~> v1.14.7"?
💡 Result:
No, Terraform version constraint syntax does not support the 'v' prefix. Version numbers must be a series of numbers separated by periods without a leading 'v', such as "> 1.14.7". Using "> v1.14.7" results in an invalid constraint error, as the 'v' prefix is not part of the expected format.

Fix invalid version constraint syntax in terraform/versions.tf.
Line 2 uses an invalid version constraint with the 'v' prefix: ~> v1.14.7. Terraform version constraints do not support the 'v' prefix. Change it to ~> 1.14.7.

🧹 Nitpick | 🔵 Trivial
Consider configuring remote state backend.
Using local state (the current configuration) in CI/CD is problematic because:
- State files are not persisted between workflow runs, leading to Terraform treating each run as a fresh deployment
- No state locking mechanism to prevent concurrent modifications
- State cannot be shared across team members or other workflows
Consider configuring a remote backend (e.g., S3, Terraform Cloud, or DigitalOcean Spaces) in terraform/versions.tf to persist state and enable state locking.
🧹 Nitpick | 🔵 Trivial
Remove unnecessary -backend=false flag.
The -backend=false flag is unnecessary since terraform/versions.tf does not configure a backend. Terraform will use local state by default without this flag.
♻️ Proposed simplification
- run: terraform init -backend=false
+ run: terraform init📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Terraform S3 backend credentials environment variables AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY
💡 Result:
Yes, Terraform S3 backend supports AWS credentials via environment variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY. Official documentation recommends using these environment variables for credentials instead of hardcoding them in configuration files to avoid exposing sensitive data in .terraform directories or plan files. To configure: - Set the environment variables before running terraform init: export AWS_ACCESS_KEY_ID="your_access_key" export AWS_SECRET_ACCESS_KEY="your_secret_key" export AWS_REGION="us-east-1" # Optional, but recommended for region - Use partial backend configuration in your Terraform code (omit credentials): terraform { backend "s3" { bucket = "your-terraform-state-bucket" key = "path/to/terraform.tfstate" region = "us-east-1" } } The S3 backend uses the AWS SDK, which automatically picks up these standard environment variables for authentication. This applies during terraform init for backend initialization and state operations. For temporary credentials (e.g., assumed roles with MFA), also set AWS_SESSION_TOKEN. Alternative methods include ~/.aws/credentials file or IAM roles, but environment variables are explicitly recommended for security in remote state setups.

Fix the Terraform S3 backend credential environment variable.
The environment variable AWS_SECRET_KEY is not recognized by Terraform's S3 backend or the AWS SDK. Terraform will have the access key but not the secret key, causing terraform init to fail during backend initialization. Use AWS_SECRET_ACCESS_KEY instead.

Terraform S3 backend use_lockfile support and DigitalOcean Spaces S3 conditional writes compatibility
💡 Result:
Terraform S3 backend supports the use_lockfile option for native S3 state locking using a .tflock lockfile and S3 conditional writes (If-None-Match header on PutObject). This feature is opt-in (defaults to false), stable as of Terraform 1.11+, and replaces deprecated DynamoDB locking. Official docs recommend bucket versioning and specific IAM permissions including GetObject/PutObject/DeleteObject on the lockfile. DigitalOcean Spaces is S3-compatible and officially supports using the Terraform S3 backend as a remote state store, explicitly including use_lockfile = true in their documentation examples (updated for Terraform 1.11+). Spaces supports the required S3 conditional writes via If-None-Match (confirmed in Spaces API reference for PutObject and GetObject operations). No known compatibility issues; DigitalOcean recommends standard S3 backend config with custom endpoint, skip validations, and use_lockfile = true for locking. Example config for Spaces: terraform { backend "s3" { endpoints = { s3 = "https://nyc3.digitaloceanspaces.com" } bucket = "your-space" key = "path/to/state.tfstate" region = "us-east-1" skip_credentials_validation = true skip_requesting_account_id = true skip_metadata_api_check = true skip_region_validation = true skip_s3_checksum = true use_lockfile = true } } Note: .terraform.lock.hcl (provider/module lockfile) is local/version-controlled and unrelated to state backend locking.

Add state locking to this shared backend.
This backend writes all production deploys to the same terraform.tfstate key with no locking configured. Concurrent deploys will race and corrupt state. DigitalOcean Spaces supports Terraform's use_lockfile option (stable in Terraform 1.11+), which uses S3 conditional writes for native state locking. Add use_lockfile = true to the backend block:
State locking configuration
backend "s3" {
bucket = "gitlab-tfstate-a2ca73"
key = "terraform.tfstate"
region = "us-east-1"
endpoints = {
s3 = "https://fra1.digitaloceanspaces.com"
}
+ use_lockfile = true
skip_credentials_validation = true
skip_metadata_api_check = true
skip_requesting_account_id = true
