How to run a spring cloud function as AWS lambda using custom java 17 base image?

Question

Java 17 is not supported by aws lambda. I need to create a lambda function using spring cloud and java 17 as base image. What dependencies I must install in my java 17 base image?

I have used this docker file.

FROM adoptopenjdk:17-jre-hotspot as base
LABEL MAINTAINER=uniphore.com

# configure the build environment


FROM base as build
\#RUN yum install -y maven
WORKDIR /src

# cache and copy dependencies

ADD pom.xml .
RUN mvn dependency:go-offline dependency:copy-dependencies

# compile the function

ADD . .
RUN mvn package

# copy the function artifact and dependencies onto a clean base

FROM base
WORKDIR /function

COPY --from=build /src/target/dependency/*.jar ./
COPY --from=build /src/target/*.jar ./

# configure the runtime startup as main

ENTRYPOINT \[ "/usr/bin/java", "-cp", "./\*", "com.amazonaws.services.lambda.runtime.api.client.AWSLambda" \]

# pass the name of the function handler as an argument to the runtime

CMD \[ "org.springframework.cloud.function.adapter.aws.FunctionInvoker::handleRequest" \]\`
