User data

user_data (optional) user data to provide when launching the instance, such as shell scripts.

  user_data                   = templatefile("${path.module}/assets/your_instance_data.tftpl", {})

Important notes:

• Updates to this field will trigger a stop/start of the EC2 instance by default.
• Do not pass gzip-compressed data via this argument; see user_data_base64 instead.
• If the user_data_replace_on_change is set then updates to this field will trigger a destroy and recreate
