AWS Lambdaコンテナでpuppeteerを動かす

$ cd puppeteer-aws-sample/hello-world
$ npm install puppeteer

const puppeteer = require("puppeteer");

exports.lambdaHandler = async (event, context) => {
  let response;
  try {
    const browser = await puppeteer.launch({
      headless: true,
      args: [
        "--no-sandbox",
        "--disable-setuid-sandbox",
        "-–disable-dev-shm-usage",
        "--disable-gpu",
        "--no-first-run",
        "--no-zygote",
        "--single-process",
      ],
    });
    const page = await browser.newPage();
    await page.goto("http://example.com/");
    const element = await page.$("body > div > h1");
    const value = await (await element.getProperty("textContent"))?.jsonValue();

    await browser.close();
    response = {
      statusCode: 200,
      body: JSON.stringify({
        message: value,
      }),
    };
  } catch (err) {
    console.log(err);
    return err;
  }

Your template contains a resource with logical ID "ServerlessRestApi", which is a reserved logical ID in AWS SAM. It could result in unexpected behaviors and is not recommended.

Commands you can use next
=========================
[*] Invoke Function: sam local invoke
[*] Test Function in the Cloud: sam sync --stack-name {stack-name} --watch
[*] Deploy: sam deploy --guided
$ sam local start-api

$ curl http://127.0.0.1:3000/hello
{"message":"Example Domain"}  

$ sam deploy --guided

Configuring SAM deploy
======================

        Looking for config file [samconfig.toml] :  Not found

        Setting default arguments for 'sam deploy'
        =========================================
        Stack Name [sam-app]: puppeteer-aws-sample
        AWS Region [ap-northeast-1]: 
        #Shows you resources changes to be deployed and require a 'Y' to initiate deploy
        Confirm changes before deploy [y/N]: 
        #SAM needs permission to be able to create roles to connect to the resources in your template
        Allow SAM CLI IAM role creation [Y/n]: 
        #Preserves the state of previously provisioned resources when an operation fails
        Disable rollback [y/N]: 
        HelloWorldFunction may not have authorization defined, Is this okay? [y/N]: y
        Save arguments to configuration file [Y/n]: 
        SAM configuration file [samconfig.toml]: 
        SAM configuration environment [default]: 

        Looking for resources needed for deployment:
         Managed S3 bucket: aws-sam-cli-managed-default-samclisourcebucket-18nh8nczmdjo9
         A different default S3 bucket can be set in samconfig.toml
         Image repositories: Not found.
         #Managed repositories will be deleted when their functions are removed from the template and deployed
         Create managed ECR repositories for all functions? [Y/n]: 

        Saved arguments to config file
        Running 'sam deploy' for future deployments will use the parameters saved above.
        The above parameters can be changed by modifying samconfig.toml
