AWS Lambda 节点 16 容器映像错误（缺少运行时 API 服务器配置）

Question

我想为 aws lambda 创建 node16 容器映像。对于 lambda 函数，我有以下 Dockerfile 和 index.js。构建图像 (docker build -t lambda-hello-world .) 工作正常但是当我调用 (docker run --rm -p 8080:8080 lambda-hello-world) lambda 函数时它 returns 错误。有人可以建议吗？

        throw new Error("Missing Runtime API Server configuration.");
        ^

index.js

exports.handler = async (event, context) => {
    return `Hello World form node version ${process.version}`;

根据此 issue，每当调用您的 Docker 图像时，无论是在 Lambda 中还是在您的本地计算机上，您都需要一个入口脚本来帮助您在必要时使用 RIE 代理（例如，在我们的本地机器上）。

entry.sh 在根项目中：

#!/bin/sh
# Check if the AWS_LAMBDA_RUNTIME_API is not set. This environment
# variable is set when the image is running on Lambda.
if [ -z "${AWS_LAMBDA_RUNTIME_API}" ]; then
  # We know the image is being run off of Lambda, so we need to use the RIE
  # to start the function.
  exec /usr/bin/aws-lambda-rie ./node_modules/.bin/aws-lambda-ric 
else
  # We know the image is being run on Lambda so we don't need to use the RIE.
  exec ./node_modules/.bin/aws-lambda-ric 
fi

您的Docker文件：

FROM node:16-alpine

# Bundle app source
COPY . .

RUN npm install

EXPOSE 8080

# Downloads the Lambda Runtime Interface Emulator (RIE)
ADD https://github.com/aws/aws-lambda-runtime-interface-emulator/releases/latest/download/aws-lambda-rie /usr/bin/aws-lambda-rie

RUN chmod +x /usr/bin/aws-lambda-rie
RUN chmod +x entry.sh

ENTRYPOINT ["entry.sh"]

CMD ["index.handler"]
