[Docker](https://www.docker.com/) is the most popular containerization platform, providing standardized software delivery capabilities.

**Pigsty does not rely on Docker to deploy any of its components; instead, it provides the ability to deploy and install Docker** — this is an **optional module**.

Pigsty offers a series of [Docker software/tool/application templates](https://pigsty.io/docs/app/) for you to choose from as needed.
This allows users to quickly spin up various containerized stateless software templates, adding extra functionality.
You can use external, Pigsty-managed highly available database clusters while placing stateless applications inside containers.

When running `configure`, Pigsty automatically selects suitable upstream repositories and mirror acceleration settings based on `region` (for example, mainland China network environments), to improve image pull speed and availability.
You can easily configure Registry and Proxy settings to flexibly access different image sources.
