AWS ECS Periodic job - automatically scales, for example

Question

Amazon ECS provides really good service for scheduled tasks: ECS scheduled tasks that work very well. However, it is important that one instance of ECS is always stored in ECS. What is the best way:

• Launch / scale in an ECS instance for a periodic job (just before the task);
• Starting ECS ​​tasks for a newly created instance;
• Finish / deploy instance after completion.

One possible way to solve the problem is to write a lambda that will do smth. ( run ec2 ), but it looks like too much pain.

Answer 1

Finally, I found an easy solution to this problem. Everything was pretty simple:

• Go to the autosave groups (this can be found in the EC2-> Autoscaling dashboard section);
• Create a planned action (in this case, the required frequency can be specified for the container instance);
• Save the configuration. The instance will be added at the specified time.
• In my case, I also need to reduce this instance in 1 hour.
