    Terragrunt by Gruntwork

    v0.87.0

    Original source

    Breaking changes announced for automatic backend provisioning: Terragrunt will no longer provision backend resources automatically. If backend provisioning is required but not explicitly enabled, Terragrunt exits with an error. To continue automatic bootstrapping, users must opt in with --backend-bootstrap or TG_BACKEND_BOOTSTRAP=true. A migration guide provides steps to adopt the new behavior. A0

    Breaking Changes

    Automatic Backend Provisioning Removed

    Terragrunt no longer automatically provisions backend resources. If backend provisioning is required but not explicitly enabled, Terragrunt will now exit with an error.

    Old Behavior (Deprecated)

    The following command would silently provision backend resources before execution: terragrunt plan --non-interactive

    New Behavior

    This behavior has been removed. Running the same command without opting in will now produce an error if backend bootstrapping is required. To continue to automatically bootstrap backends, you must explicitly enable backend provisioning with either the --backend-bootstrap flag or the TG_BACKEND_BOOTSTRAP environment variable: terragrunt plan --backend-bootstrap --non-interactive or export TG_BACKEND_BOOTSTRAP=true terragrunt plan --non-interactive

    Migration Guide
    • If you relied on automatic backend bootstrapping:
      • Add --backend-bootstrap to your Terragrunt commands, or set the TG_BACKEND_BOOTSTRAP environment variable.
    • If you don’t require backend provisioning:
      • No action needed — simply run Terragrunt commands without the flag.
    Road to 1.0 Deprecated Feature Removal Schedule

    #3535

    What's Changed
    • chore: Disabled automatic backend provisioning by @denis256 in #4703
    • docs: Updated migration docs by @yhakbar in #4711

    Terragrunt by Gruntwork

    v0.86.3

    Original source

    Shipping a patch with bug fixes and new documentation: stacks now generate in topological order; AWS account ID with provider CMD fixed; custom API endpoints properly respected; ref handling in terragrunt catalog corrected; DAG graph supports all run flags. New docs include Terragrunt Scale and a Terralith to Terragrunt guide, plus extensive changelog.

    🐛 Bug Fixes

    • Stacks now generate in topological order A race condition caused by concurrent generation of nested Terragrunt Stacks when a .terragrunt-stack directory already exists has been remediated.
    • Stacks will now generate topologically regardless of whether they are cleanly generated or generated when a terragrunt-stack directory already exists, resulting in parent stacks generating before child stacks. get_aws_account_id() interaction with --auth-provider-cmd fixed
    • A bug introduced in the upgrade to AWS SDK v2 in v0.85.1 where get_aws_account_id() would not work properly when used in conjunction with the --auth-provider-cmd flag has been remediated.
    • Custom API endpoints for backend resources are now set correctly A bug introduced in the upgrade to AWS SDK v2 in v0.85.1 where integration with the S3 and DynamoDB AWS SDK clients did not properly respect the endpoint setting for backend configurations has been remediated.
    • ref properly handled in catalog urls The use of the ref query string parameter in Catalog go-getter URLs has been fixed, allowing users to explicitly specify the ref they want to use for their catalog sources.
    • dag graph updated to support all run flags The dag graph command has been updated to support all flags supported by the run command.

    📖 Docs

    • Terragrunt Scale page published The Terragrunt Scale page has been published, showcasing a new offering from Gruntwork to help customers scale up their IaC usage. It showcases the integration Terragrunt has with commercial offerings from Gruntwork to help organizations scale their infrastructure management.
    • The Terralaght to Terragrunt has been published A step-by-step guide to transitioning IaC configurations from a Terralaght (where all resources are in a single state file) to a modern Terragrunt IaC configuration, using Terragrunt Stacks has been published named Terralaght to Terragrunt. This is the first major guide in this style, with more to come in the future to address specific pain points for members of the community in a step-by-step guide, rather than a reference or high level summary of features.
