terragrunt

Updated CLI args, config attributes and blocks

• get_original_terragrunt_dir() [NEW]
• generate
• remote_state

Description

• Added a new get_original_terragrunt_dir() helper, which returns the directory where the original Terragrunt configuration file (by default terragrunt.hcl) lives. This is primarily useful when one Terragrunt config is being read from another: e.g., if /terraform-code/terragrunt.hcl calls read_terragrunt_config("/foo/bar.hcl"), and within bar.hcl, you call get_original_terragrunt_dir(), you'll get back /terraform-code.
• Updated the generate and remote_state settings so that they can be set either as blocks or attributes. This makes it possible to, for example, read these settings from common.hcl using read_terragrunt_config and set them dynamically.

Updated CLI args, config attributes and blocks

• --terragrunt-strict-include

Description

• When you pass in --terragrunt-strict-include, Terragrunt will now only execute within the directories passed in via --terragrunt-include-dir. If you set --terragrunt-strict-include, but don't pass in any directories via --terragrunt-include-dir, then Terragrunt will exit without doing anything. This is arguably a backwards incompatible change, but this is the behavior the --terragrunt-strict-include flag was intended to have originally, and is less surprising, so we're treating this as a bug fix.

remote_state {
  backend = "s3"
  config = {
    bucket         = "my-terraform-state"
    ...
    ...
    accesslogging_bucket_name = "valid_string_for_S3_bucket_bame"

• Logging

Description

• In v0.28.0, when we switched Terragrunt to use a proper logger that supported different log levels, we set the default log level to WARN. The intention was to make Terragrunt's logging less noisy, but as an unintended side effect, we ended up suppressing some log messages that are important to see. This release changes the default log level to INFO and should fix most of the logging issues.
