| CONTAINER\_BUILD\_SUSTAINABILITY\_02: How do you support your containerized application to run on energy-efficient hardware? |

 To be able to [use instance types with the least environmental impact](https://docs.aws.amazon.com/wellarchitected/latest/sustainability-pillar/use-instance-types-with-the-least-impact.html) (from the Sustainability Pillar whitepaper), you have to ensure your containerized application is able to run on a variety of instance types and architectures. This can be done by creating images that support multi-architecture as described in the [Cost Optimization Pillar whitepaper ](https://docs.aws.amazon.com/wellarchitected/latest/cost-optimization-pillar/welcome.html). For example, you can use a build service that supports multi-architecture build servers and combine them to a multi-architecture image using the CI pipeline (see Graviton workshop as an [example](https://graviton2-workshop.workshop.aws/en/amazoncontainers.html) of using AWS CodeBuild, and AWS CodePipeline alongside Graviton and Amazon EKS). You can also use tools that generate multi-architecture images from a single Dockerfile, such as [Docker Buildx.](https://docs.docker.com/desktop/multi-arch/)
