# Deploy Docker on DCDeploy

> Guide for deploying any Dockerized application on DCDeploy

DCDeploy natively supports **Docker deployments**.\
You can bring your own **Dockerfile** or deploy directly from a **Docker image** hosted in a registry.

***

## When to Use Docker on DCDeploy

* You want **full control** over runtime, dependencies, and OS libraries.
* You’re deploying apps not natively supported by a language/framework guide.
* You already maintain **Docker images** in registries like DockerHub, GitHub Container Registry, or AWS ECR.
* You need **multi-service setups** with custom networking.

## Deployment Options

| Method           | Use Case                                                             |
| ---------------- | -------------------------------------------------------------------- |
| **Dockerfile**   | Build from your source code on DCDeploy. Best for CI/CD pipelines.   |
| **Docker Image** | Deploy prebuilt images from a container registry. Fast and portable. |

## Example: Using a Dockerfile

1. Create a `Dockerfile` in your project:
   ```dockerfile theme={null}
   FROM node:18-alpine
   WORKDIR /app
   COPY package*.json ./
   RUN npm install --production
   COPY . .
   EXPOSE 3000
   CMD ["npm", "start"]
   ```
