Usage

terraform show -json tfplan | terrasafe --config terrasafe.json

Configuration

The --config option allows to specify the path of the JSON configuration file.

{
  "ignore_deletion": [ "aws_ecs_task_definition*" ], // Resource can be deleted
  "ignore_deletion_if_recreation": [ "aws_ecs_task_definition*"], // Resource can be replaced
  "unauthorized_deletion": [ "aws_ecs_task_definition*" ] // Resource can't be deleted by any way
}

How to delete a resource ?

• Comment it
• Or rename the file with the extension .tf.disabled
• Or define the Env var TERRASAFE_ALLOW_DELETION to the addresses of resources to delete, separated by ;. Example: export TERRASAFE_ALLOW_DELETION=aws_ecs_task_definition.a;aws_lambda.b
