What happened?

When following this doc:

https://github.com/Azure/data-api-builder/blob/main/docs/running-using-a-container.md

I get the following error:

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested docker: Error response from daemon: Ports are not available: exposing port TCP 0.0.0.0:5000 -> 0.0.0.0:0: listen tcp 0.0.0.0:5000: bind: address already in use. ERRO[0130] error waiting for container: context canceled

Version

Looks like we've only build the container image for linux/amd64 which is backed up by https://github.com/Azure/data-api-builder/blob/main/.pipelines/build-pipelines.yml#L269-L310

We'll need to add a --platform flag to the task that generates linux/amd64 and linux/arm64, although I'm not sure how to do that with https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/reference/docker-v2?view=azure-pipelines&tabs=yaml

[aaronpowell]

Oh, looks like the task doesn't natively support it, nor has there been much traction to get it supported - https://github.com/microsoft/azure-pipelines-tasks/issues/16491

Might have to fall back to using scripts within the pipeline to call Docker directly.

Hi @JerryNixon,

Given the previous updates rolled out to Docker Desktop for macOS, this recommendation I gave you a few months back might not be needed anymore:

Needs:

RUN dotnet build "./src/Service/Azure.DataApiBuilder.Service.csproj" -c Docker -o /out -r linux-arm64

Otherwise: WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8), and no specific platform was requested 9ca10b1e8ad7c52c34b2db380ce24dacb73cb93518230475aa5a4a1c26ed67ff

The work around is simple, just two steps:

1. Enable the Rosetta for x86/amd64 emulation on Apple Silicon option in Docker Desktop for macOS (+13.0)
2. Run the container using the --platform linux/amd64 option, as follows:

docker run \
    --name DAB-Library \
    --volume "./DAB-Config:/App/configs" \
    --publish 5001:5000 \
    --env-file "./DAB-Config/.env" \
    --network library-network \
    --platform linux/amd64 \
    --detach mcr.microsoft.com/azure-databases/data-api-builder:latest \
    --ConfigFileName /App/configs/dab-config.json

Let me know if you have any questions.
