How to change instance type in AWS ECS cluster?

Question

I have a cluster in AWS EC2 Container Service. When I\'ve set it up, I used t2.micro instances because those were sufficient for development. Now I\'d like to use more powerful

Answer 1

Here are the exact steps I took to update the instance type on my cluster:

• Go to the cluster service, update Number of tasks to 0

• Go to EC2 -> Launch Configurations -> Actions dropdown -> Copy launch configuration and set the new instance type

• Go to EC2 -> Auto Scaling Groups -> Edit -> set Launch Configuration to newly created launch configuration

• Go to EC2 -> Auto Scaling Groups -> Instances -> Detach instance

• Go to EC2 -> Launch Configurations -> Delete old launch configuration

• Go to the cluster service, update Number of tasks to your desired count.

Now when tasks start, it'll be running on the updated EC2 instance type.
