在lambda nodejs 12.0上安装libreoffice，但部署时无法运行命令

Question

我尝试将libreoffice安装到lambda函数的docker映像中。当我在本地机器上运行它时，它工作正常，但当将映像部署到lambda函数时，它一直在说“无法从javaldx读取路径”，并且无法打开soffice。有什么解决办法吗？以下是DockerFile：

FROM public.ecr.aws/lambda/nodejs:12

RUN yum install wget tar -y
RUN yum install java-1.8.0-openjdk-devel -y
RUN mkdir "LibreOffice_7.2_Linux_x86-64_rpm"
ADD LibreOffice_*_Linux_x86-64_rpm ./LibreOffice_7.2_Linux_x86-64_rpm
RUN ls -la
RUN cd  LibreOffice_*_Linux_x86-64_rpm && cd RPMS && yum -y localinstall *.rpm
RUN chmod -R 777 /opt/libreoffice7.2
ADD test.docx ./
RUN export HOME=/tmp

COPY index.js package*.json ./
RUN npm install

CMD [ "index.handler" ]

这是我的处理程序代码：

/* Amplify Params - DO NOT EDIT
    ENV
    REGION
    STORAGE_DOCBACKENDD3C9A483_BUCKETNAME
Amplify Params - DO NOT EDIT */

const {writeFileSync, readFileSync} = require('fs');
const {execSync} = require('child_process');
const {S3} = require('aws-sdk');

const s3 = new S3(
    {
        params: {
            Bucket: "documentgenerationb25c0536d4054b9faeafca747e3f295559-dev",
            apiVersion: '2006-03-01'
        }
    }
);
const convertCommand = `/opt/libreoffice7.2/program/soffice --convert-to pdf test.docx --headless`;

exports.handler = async () => {
    const filename = "test.docx"
    const {Body: inputFileBuffer} = await s3.getObject({Key: `public/${filename}`}).promise();
    writeFileSync(`/tmp/${filename}`, inputFileBuffer);

    execSync(`${convertCommand} ${filename}`);
    const outputFilename = `test1-brandon.pdf`;
    const outputFileBuffer = readFileSync(`/tmp/${outputFilename}`);

    await s3
    .putObject({
        Key: `public/${outputFilename}`, Body: outputFileBuffer,
        ACL: 'public-read', ContentType: 'application/pdf'
    })
    .promise();

    return `https://documentgenerationb25c0536d4054b9faeafca747e3f295559-dev.s3.amazonaws.com/public/${outputFilename}`;
};

Answer 1

我目前正在使用这个https://github.com/shelfio/aws-lambda-libreoffice一个lambda层，你只需要安装@Shelch/AWS-lambda-libreoffice。所以它实际上只有4行无服务器部署的代码。

看起来这个答案警告：未能从javaldx读取路径也适用于您的情况。

您的用户没有主文件夹集，或者主文件夹不可写。我刚从直接调用libreoffice改为通过shell脚本调用它
