Azure IoT Edge image build for AMD64, Arm64v8 in azure devops pipeline with supported Microsoft hosted agents

Question

Azure IoT Edge image build for AMD64, Arm64v8 in azure devops pipeline with supported Microsoft hosted agents

Dhanavath Vishnu 366

Hi Team,

I have scenario, where I am building two types of images of same repo, using Azure IoT Edge Task (AzureIoTEdge@2). Just I am looping this IoT Edge Task for different platform, by replacing defaultPlatform: with two architectures (AMD64, Arm64v8). The build of IoT edge image is getting successful, but the Arm64v8 image build is happening for linux/amd64 platform only, because the Agent we are using in the pipeline is Microsoft hosted agent ubuntu-latest, it seems that by default this is amd64 hosted agent.

As we are using same hosted agent for both images build (AMD64, Arm64v8), this error is we are getting, if we want to run the Microsoft hosted agent for Arm64v8 image build, how should we setup these two host platforms in our pipeline run?

Please help me out on this issue.

Thanks

D. Vishnu

Hi @LeelaRajeshSayana-MSFT ,

I have found a solution for this issue, I am updating it here, please do review with your support team, is this standard practice to use these tasks in the azure pipeline. If it is standard practice, the community can use this method for the multiarchitecture IoT Edge image builds.

The solution which I found is depends on Buildx commands, we need to install it on the Pipeline Agent and run the series of buildx commands. The Filepath should contain the Dockerfile in the repository.

Thank you.
