What determines what version of docker compose is installed on the Elastic CI Stack for AWS?

At the time of writing it comes with 1.29.2 ([Elastic CI Stack for AWS | Buildkite Documentation](https://buildkite.com/docs/agent/v3/elastic-ci-aws#whats-on-each-machine)) but I need at least v2.4.1 as would like to use the ssh build option (ref: [Docker Compose release notes | Docker Documentation](https://docs.docker.com/compose/release-notes/#241))

To answer my own question: docker and docker compose are baked in to the AMIs used by the cloudformation template, config comes from: [elastic-ci-stack-for-aws/install-docker.sh at master · buildkite/elastic-ci-stack-for-aws · GitHub](https://github.com/buildkite/elastic-ci-stack-for-aws/blob/master/packer/linux/scripts/install-docker.sh)

FWIW, looking at [Add docker compose v2 to linux by donbobka · Pull Request #1052 · buildkite/elastic-ci-stack-for-aws · GitHub](https://github.com/buildkite/elastic-ci-stack-for-aws/pull/1052/files), perhaps docker compose v2 is already installed 🎉

HI @jkburges,

Welcome to the Buildkite Community! 👋🏼

It’s great that you have found the references from [GitHub - buildkite/elastic-ci-stack-for-aws: An auto-scaling cluster of build agents running in your own AWS VPC](https://github.com/buildkite/elastic-ci-stack-for-aws).

You could also explore building your own Elastic CI Stack if you want to have more control on the contents of your AWS instances.
