# Customizing Docker images for Amazon EMR on EKS
<a name="docker-custom-images"></a>

You can use customized Docker images with Amazon EMR on EKS. Customizing the Amazon EMR on EKS runtime image provides the following benefits: 
+ Package application dependencies and runtime environment into a single immutable container that promotes portability and simplifies dependency management for each workload.
+ Install and configure packages that are optimized to your workloads. These packages may not be widely available in the public distribution of Amazon EMR runtimes.
+ Integrate Amazon EMR on EKS with current established build, test, and deployment processes within your organization, including local development and testing.
+ Apply established security processes, such as image scanning, that meet compliance and governance requirements within your organization.
