In Part 1 of this series, we built a PowerShell script that automates the process of pulling a public Docker image from Docker Hub and pushing it to your Azure Container Registry (ACR). In this second part, we'll focus on integrating that script into a CI/CD pipeline using GitHub Actions. This logic will ensure that our image management process is fully automated and runs on a scheduled basis.

With GitHub Actions, you can schedule the execution of your script, monitor its output, and ensure that your ACR is always updated with the latest image—without any manual intervention. Let’s walk through how to configure your GitHub Actions workflow.

Keeping your container images up to date is a critical part of managing modern deployments. In this article, I'll explain how you can automate the process of pulling a public Docker image from Docker Hub and pushing it to your Azure Container Registry (ACR) using a PowerShell script. This approach is especially useful for overcoming Docker Hub’s rate limits by storing the image in your ACR.

This article is part of a two-part series where I demonstrate how to build an automated process that leverages a Service Principal with Federated Credentials and strict Role-Based Access Control (RBAC) assigment. With RBAC in place, only the necessary permissions are granted, ensuring that the Service Principal has the least privileges required for this operation. In this example, we'll use the Cloudflare image as our reference, but you can adapt the process for any public image.
