Node.js 关闭Docker容器上的木偶演员脚本

目前，我正在EC2实例上的docker容器中运行一个木偶脚本（每小时一次）。下面是代码（如果您正在阅读此文件，请感谢您Edi Imanto）

你需要这样做。请按照下面的说明。简而言之，您需要使用

--init

选项运行容器，以启动一个简单的进程，如PID 0，该进程将负责在铬实例与Puppeter分离后获取铬实例

const cron = require('node-cron')
const execute = require('child_process').exec
const puppeteer = require('puppeteer')
const processIDs = []

const createBrowser = async () => {
    const browser = await puppeteer.launch()
    processIDs.push(browser.process().pid)
    return browser
}

const closeBrowser = async (browser) => {
    await browser.close()
    for (let i = 0; i < processIDs.length; i++) {
        execute(`kill -9 ${processIDs[i]}`)
    }
}


const runHourly = async () => {
    const browser = await createBrowser()    
    const await = doSomething()  

    const closeTab = await page.close()
    const exit = await closeBrowser(browser)
}

cron.schedule('* 0/1 * * *', () => {
    await runHourly()
})
