[Question] Nodejs20-debian12 with aws-lambda-ric #1730

I'm a person with very little node knowledge, but could you just run the index.js in aws-lambda-ric directly? The ENTRYPOINT provided by distroless is and your CMD is |

I've played around with it, and it might not be possible with distroless because it expects FROM gcr.io/distroless/nodejs22-debian12:latest
COPY --from=public.ecr.aws/lambda/nodejs:22 /usr/local/bin/aws-lambda-rie /usr/local/bin/aws-lambda-rie
COPY --from=public.ecr.aws/lambda/nodejs:22 /var/runtime /var/runtime
ENV LAMBDA_TASK_ROOT=/var/task
WORKDIR /var/task
COPY index.js ${LAMBDA_TASK_ROOT}
ENTRYPOINT [ "/usr/local/bin/aws-lambda-rie" ]
CMD [ "/nodejs/bin/node", "/var/runtime/index.mjs" "index.handler" ]Where index.js is exports.handler = async (event) => {
const response = {
statusCode: 200,
body: JSON.stringify('Hello from Distroless Lambda!'),
};
return response;
};And running it as docker run --rm -it -p 8080:8080 lambdaAnd I get the following logs If I somehow manage to sneak in If I use the docker run --rm -it -p 8080:8080 --entrypoint /busybox/sh lambdaAnd then run this inside the container /usr/local/bin/aws-lambda-rie /nodejs/bin/node /var/runtime/index.mjs index.handlerI can actually curl it and get a response (takes a few tries, not sure if that's how it works, not familiar with AWS lambda). ❯ curl "http://localhost:8080/2015-03-31/functions/function/invocations" -d '{}'
{"statusCode":200,"body":"\"Hello from Distroless Lambda!\""} |

With some extra digging, I've come up with this FROM gcr.io/distroless/nodejs22-debian12:debug
COPY --from=public.ecr.aws/lambda/nodejs:22 /usr/local/bin/aws-lambda-rie /usr/local/bin/aws-lambda-rie
COPY --from=public.ecr.aws/lambda/nodejs:22 /var/runtime /var/runtime
ENV LAMBDA_TASK_ROOT=/var/task
WORKDIR /var/task
COPY index.js ${LAMBDA_TASK_ROOT}
COPY start.sh ${LAMBDA_TASK_ROOT}
ENTRYPOINT [ "/busybox/sh" ]
CMD [ "/var/task/start.sh" ]start.sh file /busybox/sh -c "/usr/local/bin/aws-lambda-rie /nodejs/bin/node /var/runtime/index.mjs index.handler"I can now start the container docker run --rm -it -p 8080:8080 lambdaAnd curl it |

Hey, we are currently running into issues while migrating onto an distroless image for our aws lambdas. I was following the docs from aws on how to use a non-AWS base image (https://docs.aws.amazon.com/lambda/latest/dg/nodejs-image.html#nodejs-image-clients).
Since the distroless image has removed package managers and everything else. NPM and NPX are not availabe. But I couldn't find any documentation what I could give as an entrypoint in the dockerfile for the aws-lambda-ric as an alternative. The documentation mentioned above expects the following entrypoint:
Do any of you have experience in what seems to be an edge case?
