Same. Especial part

Render the User Data script as a template

user_data = templatefile("user-data.sh", { server_port = var.server_port db_address = data.terraform_remote_state.db.outputs.address db_port = data.terraform_remote_state.db.outputs.port })

Cant understand how var share porn from one file to another. Server didn't run. 502
