Auto-Retry is a feature of
terragrunt that will automatically address situations where a
terraform command needs to be re-run.
Terraform can fail with transient errors which can be addressed by simply retrying the command again. In the event
terragrunt finds one of these errors, the command will be re-run again automatically.
$ terragrunt apply ... Initializing provider plugins... - Checking for available provider plugins on https://releases.hashicorp.com... Error installing provider "template": error fetching checksums: Get https://releases.hashicorp.com/terraform-provider-template/1.0.0/terraform-provider-template_1.0.0_SHA256SUMS: net/http: TLS handshake timeout.
Terragrunt sees this error, and knows it is a transient error that can addressed by re-running the
auto-retry will try a maximum of three times to re-run the command, at which point it will deem the error as not transient, and accept the terraform failure. Retries will occur when the error is encountered, pausing for 5 seconds between retries.
Known errors that
auto-retry will rerun, are maintained in the
TerragruntOptions.RetryableErrors array. Future upgrades to
terragrunt may include the ability to configure
auto-retry by specifying additional error strings and configuring max retries and retry intervals the
terragrunt config (PRs welcome!).
auto-retry, use the
--terragrunt-no-auto-retry command line option or set the
TERRAGRUNT_AUTO_RETRY environment variable to
