user_data not applicable for launch templates

[baztian]

Description

Setting up a launch template using this module does not work if you're using user_data.

Versions

Terraform v0.14.6

• provider registry.terraform.io/hashicorp/aws v3.41.0
• provider registry.terraform.io/hashicorp/null v3.1.0
• provider registry.terraform.io/hashicorp/random v3.1.0
• provider registry.terraform.io/hashicorp/template v2.2.0
  • Module: 4.1.0

Reproduction

Steps to reproduce the behavior: Apply a stack with

  use_lt = true
  create_lt = true
  user_data = "..."

Expected behavior

A lauch template with the user_data is created.

Actual behavior

A launch template without any user_data is created.

Additional context

When using user_data_base64 instead everything works fine.

unlike launch configurations, launch templates take user data but it must be already base64 encoded (launch config has provisions for plain user data and user data thats base64 encoded). therefore, because the module was updated to accommodate both launch configs and launch templates, we pass in the user_data_base64 into the launch template because it only accepts base64 encoded user data

Hi, Can you add this to the module documentation? Thanks!

+1 for updating the doc - user_data is not working

[bryantbiggs]

hi all - for as much time as it took here to post a message, a PR could have been opened to address this (per the doc update that is)
