# 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](/docs/automation-platform/overview-1/prerequisites/docker/docker-registry-credentials.md): 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](/docs/automation-platform/overview-1/prerequisites/docker/shell-access-for-docker.md): This section guides Native Docker users through setting up a Docker shell to access the command-line interface for building, running, and managing containers. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
