如何让剧作家在码头容器上工作并将其部署到AWS Lambda

Question

我按照本教程将剧作家安装在一个码头容器上，然后尝试将其部署到AWS函数：https://tech.smartshopping.co.jp/lambda-container-playwright

在执行了所有步骤之后，我一直得到以下错误：

╔══════════════════════════════════════════════════════╗
║ Host system is missing dependencies to run browsers. ║
║ Missing libraries:                                   ║
║     libasound.so.2                                   ║
╚══════════════════════════════════════════════════════╝

这是我的码头文件：

FROM public.ecr.aws/lambda/python:3.9-arm64

ENV  PLAYWRIGHT_BROWSERS_PATH=/var/task/bin

RUN yum -y update && yum -y install libXScrnSaver gtk2 gtk3 alsa-lib.x86_64

RUN mkdir /var/task/bin

COPY /app/main.py requirements.txt ./

RUN python3.9 -m pip install --upgrade pip &&  \
    python3.9 -m pip install -r requirements.txt && \
    python3.9 -m playwright install chromium

# Command can be overwritten by providing a different command in the template directly.
CMD ["main.lambda_handler"]

我尝试在第一个运行命令中安装缺少的库，更改如下：

RUN yum -y update && yum -y install libXScrnSaver gtk2 gtk3 alsa-lib.x86_64

至：

RUN yum -y update && yum -y install libXScrnSaver libasound.so.2 gtk2 gtk3 alsa-lib.x86_64

但这只会导致同样的错误。因此，我尝试在第三个RUN命令中安装lib，更改如下：

RUN python3.9 -m pip install --upgrade pip &&  \
    python3.9 -m pip install -r requirements.txt && \
    python3.9 -m playwright install chromium

至：

RUN python3.9 -m pip install --upgrade pip &&  \
    python3.9 -m pip install -r requirements.txt && \
    python3.9 -m playwright install chromium && \
    python3.9 -m pip install libasound.so.2

但这再次导致了同样的错误被产生。

如何安装缺少的库以修复错误？

编辑：

通过改变这一行来修正：

RUN yum -y update && yum -y install libXScrnSaver libxtst6 gtk2 gtk3 alsa-lib.x86_64

至：

RUN yum -y update && yum -y install libXScrnSaver libxtst6 gtk2 gtk3 alsa-lib.aarch64

但是现在得到了错误：

pid=68\n[pid=68][err] 
/var/task/bin/chromium-1005/chrome-linux/chrome: 
/lib64/libm.so.6: version `GLIBC_2.27' not found 
(required by /var/task/bin/chromium-1005/chrome-linux/chrome)\n

Answer 1

你试过把它作为二进制包下载吗？

也许您可以查看一下这个libasound.so.2包页面，看看是否可以下载它。

wget https://vault.centos.org/centos/8/AppStream/aarch64/os/Packages/alsa-lib-1.2.5-4.el8.aarch64.rpm

当我在apt，ubuntu包工具中搜索时，我没有看到任何东西

root@21be95fca6e6:/# apt search libasound.so.2

例如，Vim包如下所示

root@21be95fca6e6:/# apt search vim
