This module is not strictly a module which the same settings as the other AWS resources. This is a module which allows users to create the EC2 compute resources necessary to run the ECS Containers on top of EC2 workloads.
At this point in time, there is no support for creating Capacity providers in CloudFormation, therefore we cannot implement that functionality.
By default, everything is built to use EC2 spot fleet, simply to save money on deployment for testing. Future will allow to run pure OnDemand or hybrid mode.
Define settings in the configs section¶
At the moment, the settings you can change for the compute definition of your EC2 resources are defined in
configs -> globals -> spot_config
x-configs: spot_config: bid_price: 0.42 use_spot: true spot_instance_types: m5a.xlarge: weight: 4 m5a.2xlarge: weight: 8 m5a.4xlarge: weight: 16
With the given AZs of your region, it will create automatically all the overrides to use the spot instances.
This spotfleet comes with a set of predefined Scaling policies, in order to further reduce cost or allow for scaling out based on EC2 metrics.
We cannot recommend any more to use AWS Fargate and configure your capacity providers instead of EC2 instances. Use with caution
