terragrunt

Updated CLI args, config attributes and blocks

• Auto Init

Description

When creating an S3 bucket for state storage, Terragrunt will now add an IAM policy that only allows the S3 bucket to be accessed via TLS. You can disable this policy (NOT recommended!) via the skip_bucket_enforced_tls setting.

• remote_state

Description

The lock_table attribute for the s3 remote state backend is now marked as deprecated and terragrunt will automatically convert it to the preferred dynamodb_table attribute. This means that existing configurations using the lock_table attribute will need to be reinitialized.

• aws-provider-patch [NEW CLI COMMAND]

Description

We've added a new aws-provider-patch command that can be used to override attributes in nested provider blocks. This is an attempt at a hacky workaround for a Terraform bug where import does not work if you are using any modules that have provider blocks with dynamic variables nested within them. With this release, you can run:

terragrunt aws-provider-patch --terragrunt-override-attr region=eu-west-1

And Terragrunt will:

1. Run init to download the code for all your modules into .terraform/modules.
2. Scan all the Terraform code in .terraform/modules, find AWS provider blocks, and hard-code the region param to eu-west-1 for each one.

Once you do this, you'll hopefully be able to run import on that module. After that, you can delete the modified .terraform/modules and go back to normal.

Description

This release introduces a new CLI flag --terragrunt-debug which can be used to initiate debug mode for terragrunt.
