# Docker

This section includes optional configurations for DuploCloud users managing Docker-based deployments in GCP. These configurations help optimize workflows and ensure containerized applications are securely managed and efficiently deployed. It includes two subsections: 

* [Docker Registry Credentials](https://docs.duplocloud.com/docs/automation-platform/overview-1/prerequisites/docker/docker-registry-credentials): This page explains how to configure credentials for external Docker registries such as Docker Hub, Amazon ECR, or private repositories. 
* [Setting up a Shell for Docker](https://docs.duplocloud.com/docs/automation-platform/overview-1/prerequisites/docker/shell-access-for-docker): This section guides Native Docker users through setting up a Docker shell to access the command-line interface for building, running, and managing containers.
