+[Docker](https://www.docker.com/) is a tool that enables you to create, deploy, and manage lightweight, stand-alone packages that contain everything needed to run an application. It can help us to avoid conflicting dependencies when we edit the doc and publish gh-pages.
+
+## Run the local webserver in docker
+
+You need to ensure you have install [docker](https://www.docker.com/get-started) and install docusaurus correctly.
+
+To run the local webserver you only need to do a few step:
+
+1. Enter the folder where you have install docusaurus, and then run `docker build -t docusaurus-doc .`
+    
+    After the build phase finished, you can run `docker images` to check the docker image list.
+    
+    > We have already added a `Dockerfile` in your project when you install docusaurus, So you can build it directly.
+
+2. Run docker start command: `docker run --rm -p 3000:3000 docusaurus-doc`
+
+    It will run a container with the image `docusaurus-doc`.And you can run `docker ps` to see the container info.
+
+## Use docker-compose 
+
+We can use docker-compose to configure our application, run it with a single command.
+
+> Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration. 
+
+Using Compose is basically a three-step process:
+
+1. Define your app’s environment with a Dockerfile so it can be reproduced anywhere.
+
+2. Define the services that make up your app in docker-compose.yml so they can be run together in an isolated environment.
+
+3. Run docker-compose up and Compose starts and runs your entire app.
+
+We have already added a basic `docker-compose.yml` in your project:
+``` yml
+version: "3"
+
+services:
+  docusaurus:
+    build: .
+    ports:
+      - 3000:3000
+      - 35729:35729
+    volumes:
+      - ./docs:/app/docs
+      - ./website/blog:/app/website/blog
+      - ./website/core:/app/website/core
+      - ./website/i18n:/app/website/i18n
+      - ./website/pages:/app/website/pages
+      - ./website/static:/app/website/static
+      - ./website/sidebars.json:/app/website/sidebars.json
+      - ./website/siteConfig.js:/app/website/siteConfig.js
+    working_dir: /app/website
+
+```
+
+To run a local webserver with `docker-compose` you only need to run `docker-compose up`.
+
+If you want to build static HTML pages and publish, you can run `docker-compose run docusaurus bash -c 'yarn publish-gh-pages'`
