terraform-shell-resource
This module runs a command as a null_resource and makes the stdout, stderr and exit status available as outputs (with temporary files stored in the module). See an external data source version with more features at https://github.com/matti/terraform-shell-outputs (that runs on every apply, this one only runs once when the resource is created).
warning there is a support for trigger to re-run the module, but while it runs the command it does not update the outputs! There is nothing we can do before related issues (see below) are fixed.
module "files" {
source = "matti/resource/shell"
command = "ls -l"
}
output "my_files" {
value = "${module.files.stdout}
}
