Introduction

Scarf Gateway is a service that provides a central access point to your containers and packages, no matter where you host them.

In this guide, you will learn:

  • How to create track pulls of your Docker containers with Scarf
  • How to create a tracking pixel to track views of your package's documentation
  • How to download your packages and fetch associated pixels

Prerequisites

  • You will need to sign up for a Scarf account. You can sign up with a valid email address or your GitHub account.
  • The container you're looking to track must be published to an existing public registry, eg Docker Hub, GitHub Container Registry. This guide will use the hello-world docker image.

  1. Once signed in to Scarf, navigate to the home page.

  2. Click plus icon in the top navigation, then select New Package. Create a new package

  3. In the first drop-down click on the package type you would like to create. For this section you will click Docker. Enter the docker pull command

Now you’re all set to start tracking your Docker images with Scarf. Any time your image is downloaded, Scarf will report some basic information:

  • System and OS statistics of your users
  • Company information of your users
  • Downloads by versions/tags

In the next section, you will create a tracking pixel that can be added to your project’s documentation or any other web properties associated with your project.

  5. Finally click Submit

  6. Copy the newly created pixel <img> tag and add it to your website, documentation, or any other web properties associated with your project.
