Launch Template

testgrinder service will be discontinued on January 31, 2025

testgrinder SMPC was discontinued as of February 1, 2024

Launch Templates allow you to capture all parameters you enter when launching a new EC2 instance. The launch template you create will be used by Auto Scaling Group to launch tg-app server instances.

You can manage launch templates on the Launch Templates page in AWS EC2 console at https://console.aws.amazon.com/ec2

Prepare User Data

When defining tg-app launch template you will need to provide User Data that tg-app servers will use on launch to provision configuration files. The easiest way to prepare user data is by exporting it from the standalone tg-app instance that you already have running if you followed this deployment guide. Once the user data is exported, you may need to make some adjustments to it, for example to specify the URI of the database. See Configuration Files for how to work with user data.
