+
+[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 & unwanted behavior when running Docusaurus.
+
+## Run the local webserver in docker
+
+Ensure you have previously installed [docker](https://www.docker.com/get-started).
+
+To run the local webserver:
+
+1. **Build the docker image** -- Enter the folder where you have Docusaurus installed. Run `docker build -t docusaurus-doc .`
+
+    Once the build phase finishes, you can verify the image exists by running `docker images`.
+
+    > We now include a `Dockerfile` when you install Docusaurus.
+
+2. **Run the Docusaurus container** -- To start docker run `docker run --rm -p 3000:3000 docusaurus-doc`
+
+    This will start a docker container with the image `docusaurus-doc`. To see more detailed container info run `docker ps` .
+
+## Use docker-compose
+
+We can also use `docker-compose` to configure our application. This feature of docker allows you to run the webserver and any additional services 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 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 include 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` run `docker-compose up`.
+
+To build static HTML pages for publishing run `docker-compose run docusaurus bash -c 'yarn publish-gh-pages'`
