How do I use the EC2 based ECS Deploy Runner?

[yorinasub17]

I have configured the ECS Deploy Runner with an EC2 worker pool, but every run is automatically being routed to Fargate. How do I use the EC2 instances?

[yorinasub17]

The default launch type to use is controlled by the container_default_launch_type input variable in the ecs-deploy-runner module, which defaults to FARGATE. You can update that to EC2 to always prefer the EC2 instances.

You can also specify the launch type on a per run basis using the --task-launch-type option to the infrastructure-deployer call.

For users who have not yet configured the ECS Deploy Runner with EC2 backed ECS Cluster, you can follow the following steps:

• Copy and modify this build AMI script in our examples. Note that it should go to the same place in your infrastructure-live repository.
• Run the build script manually (NOTE: you need to have infrastructure-deployer installed), or check it in to have the ECS Deploy Runner build the AMI for you.
• Once the AMI is available, update the envcommon file for the ecs-deploy-runner to include the input variable for configuring EC2 based workers.
• Make the changes in the above answer to default to using EC2 backed workers.
