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

Yes, you can achieve this in CloudFormation.

• Click on the Stack corresponding to your ECS-Cluster.
• Click Update Stack
• Use radiocurrent template, Next
• change EcsInstanceType
• Next, Next, Update
• Upscale your cluster to 2*n instances
• Wait for the n new instances of the new type being created
• Downscale your cluster to n
• Or you could just drain and terminate the instances 1 by 1
