You’ll notice that we did not add an ENTRYPOINT or a CMD to our Dockerfile. Next, we COPY our index.html file into the /usr/share/nginx/html directory inside the container overwriting the default index.html file provided by nginx:latest image.

This will pull the nginx:latest image to our local machine and then build our custom image on top of it. On line 1, you can see we do this using the FROM command. We start building our custom image by using a base image. index.html /usr/share/nginx/html/index.html In the same directory, create a file named Dockerfile and paste the below commands. To build a custom image, we’ll need to create a Dockerfile and add our commands to it.

There are a couple of options available but one of the most portable and simplest ways to do this is to copy our html files into the image by building a custom image.

In this directory add an index.html file and add the following html to it: Let’s create a custom html page and then serve that using the nginx image.Ĭreate a directory named site-content. With mounted volumes, we are able to link a directory on our local machine and map that directory into our running container. A fairly simple way to do this is use a mounted volume. We need to get our html files into this directory. $ docker stop web Adding Custom HTMLīy default, Nginx looks in the /usr/share/nginx/html directory inside of the container for files to serve.

Open your favorite browser and navigate to You should see the following NGINX welcome page. You also named the container web using the -name option. With the above command, you started running the container as a daemon ( -d) and published port 8080 on the host network. $ docker run -it -rm -d -p 8080:80 -name web nginx Run the following command to start the container. Let’s run a basic web server using the official NGINX image. You can also see all the tags that are available by clicking on the “Tags” tab Running a basic web server On the image details screen, you are able to view the description of the image and it’s readme. Now click on the nginx result to view the image details. You will see the “OFFICIAL IMAGE” label in the top right corner of the search entry. The official NGINX image should be the first image in the search results. Once you have logged into Docker, enter “NGINX” into the top search bar and press enter. If you do not have a Docker account yet, you can create one for free. Open your favorite browser and log into Docker. Let’s take a look at the NGINX official image. These images have clear documentation, promote best practices, and are designed for the most common use cases. Official Images are a great place for new Docker users to start.

The Docker Official Images are a curated set of Docker repositories hosted on Docker Hub that have been scanned for vulnerabilities and are maintained by Docker employees and upstream maintainers. An IDE or text editor to use for editing files.

In this tutorial we will take a look at the NGINX Official Docker Image and how to use it. Not only is NGINX a fast and reliable static web server, it is also used by a ton of developers as a reverse-proxy that sits in front of their APIs.
