Integration test failed during docker build

0.234 exec /bin/sh: exec format error
#9 ERROR: executor failed running [/bin/sh -c apt-get update]: exit code: 1

I think this is usually from a mismatch between the architectures of the image and the host?
So maybe we just need to provide the architecture param by changing this line to

docker buildx build -t datadog-lambda-layer-ruby:$1 . --no-cache \
        --build-arg "image=lambci/lambda:build-ruby${1}"  \
        --build-arg "runtime=${1}.0" \
        --platform linux/${arch} \

Awesome job on this Jordan!

Do we only ship /opt/ruby to the client? Nothing else is needed for the layer? @duncanista

[duncanista]

That is correct, since this layer is later merged in the AWS Lambda runtime /opt/ruby, this is enough to make it work!
