+
+# Running a NodeJS application in Docker
+
+We will be using the guide [Creating a Simple REST API](/guides/nodejs/pages/creating-a-simple-rest-api) as the example application.
+
+## Prerequisites
+
+- Docker installed
+- Docker Compose installed
+
+## Get Started
+
+1. First we need to create a new file called `Dockerfile`.
+
+2. Next, we need to open the `Dockerfile` file and add the following code:
+
+```dockerfile
+FROM node:latest
+
+WORKDIR /app
+
+COPY package*.json ./
+
+RUN npm install
+
+COPY . .
+
+EXPOSE 3000
+
+CMD ["node", "index.js"]
+```
+
+3. Now we can move on to the `docker-compose.yml` file. We need to create a new file called `docker-compose.yml`.
+
+4. Next, we need to open the `docker-compose.yml` file and add the following code:
+
+```yaml
+version: "3.9"
+
+services:
+  nodejs_rest_api:
+    build: .
+    restart: unless-stopped
+    ports:
+      - "3000:3000"
+```
+
+This will create a new service called `nodejs_rest_api` and build the Docker image using the `Dockerfile` in the current directory.
+
+5. You can now copyy the project files to where you want to run the application.
+
+6. Next, we need to open the terminal and run the following command:
+
+```bash
+docker-compose up -d
+```
+
+This will start the application in the background.
+
+7. Next, we need to open a web browser and navigate to `http://server_ip:3000`.
+
+You should now see your application running.
+
+## Updating the application
+
+1. First we need to open the terminal and run the following command:
+
+```bash
+docker-compose down
+```
+
+This will stop the application.
+
+2. Next, we need to update the application files. You can do this by copying the updated files to the server.
+
+3. Next, we need to open the terminal and run the following command:
+
+```bash
+docker-compose build
+```
+
+This will re-build the Docker image.
+
+4. Next, we need to open the terminal and run the following command:
+
+```bash
+docker-compose up -d
+```
+
+This will start the application in the background again.
+
+## Finished
+
+You have now successfully created a NodeJS application and run it in Docker and know how to update it.
