在Docker容器中运行Google Lighthouse的问题

Question

我正在尝试在Docker容器中运行lighthouse，以便最终部署到AWS Lambda(使用其新的Docker映像Lambda部署)。然而，我得到一个错误，我似乎不能理解。

以下是我的dockerfile

FROM amazon/aws-lambda-nodejs:12
ENV AWS_LAMBDA_FUNCTION_MEMORY_SIZE=10240
RUN curl https://intoli.com/install-google-chrome.sh | bash
copy package.json .
RUN npm install
COPY app.js .
CMD ["app.handler"]

以下是我的app.js

const chromeLauncher = require("chrome-launcher");
const lighthouse = require("lighthouse");
exports.handler = async (event) => {
const chrome = await chromeLauncher.launch({
logLevel: "info",
chromeFlags: [
"--headless",
"--no-sandbox",
"--disable-gpu",
"--disable-dev-shm-usage",
"--single-process",
],
});
const results = await lighthouse("https://example.com", {
port: chrome.port,
disableStorageReset: true,
onlyCategories: ["performance"],
logLevel: "info",
});
return {
statusCode: 200,
results,
};
};

，日志输出如下。它似乎可以连接到灯塔，但它在发送的第一个命令/

上挂起了

要在AWS Function Lambda上运行，应该使用

const chromium = require("chrome-aws-lambda");
const chrome = await chromium.puppeteer.launch({
args: [
...chromium.args,
"--disable-dev-shm-usage",
"--remote-debugging-port=9222",
],
defaultViewport: chromium.defaultViewport,
executablePath: await chromium.executablePath,
headless: chromium.headless,
ignoreHTTPSErrors: true,
});
const options = {
logLevel: "info",
output: "html",
onlyCategories: ["performance"],
preset: "mobile",
port: 9222,
};
const runnerResult = await lighthouse(`${body.url}`, options);

但是，我在性能类别中遇到了错误，没有办法使它工作，所有其他类别都工作良好。
