It is common practice to have the Azure Container Registry behind a firewall and inaccessible from the outside world. Additionally, it is common practice to prevent AKS from loading images from public Docker Repositories. These two practices make it difficult to deploy images to the AKS cluster.
This tool aims to make this process easier by allowing you to sync images from a Docker Registry to the private Azure Container Registries.
How it works
This tool is split into 3 different steps:
ExportExistingImages
The first step is meant to be ran on your private Azure DevOps agents which have access to the Azure Container Registry. This step will export all the image names and tags to a json file. Your CI/CD pipeline should save this file to the Pipeline Artifacts and make it accessible to the next step.
ExportMissingImages
The second step is meant to be ran on the Microsoft Hosted Azure DevOps agents and will pull all the images and tags from the Docker Registries that you are missing and save them to a json file. Your CI/CD pipeline should save this file to the Pipeline Artifacts and make it accessible to the next step.
ImportMissingImages
This final mode is meant to be ran on your private Azure DevOps agents. It will load the image json from the previous step and import them to your private Azure Container Registry.
