You should find Puppeteer executes successfully, provided proper Chrome flags are used. Chrome will write into /tmp instead.Īdd your JavaScript to your container with a COPY instruction. disable-dev-shm-usage – This flag is necessary to avoid running into issues with Docker’s default low shared memory space of 64MB.If you’re uncomfortable with this, you’ll need to manually configure working Chrome sandboxing, which is a more involved process. It’s vital you ensure your Docker containers are strongly isolated from your host. Using these flags could allow malicious web content to escape the browser process and compromise the host.
To skip the download, see Environment variables. no-sandbox and disable-setuid-sandbox – These disable Chrome’s sandboxing, a step which is required when running as the root user (the default in a Docker container). To use Puppeteer in your project, run: npm i puppeteer or 'yarn add puppeteer' Note: When you install Puppeteer, it downloads a recent version of Chromium (170MB Mac, 282MB Linux, 280MB Win) that is guaranteed to work with the API.Setting this flag explicitly instructs Chrome not to try and use GPU-based rendering. disable-gpu – The GPU isn’t usually available inside a Docker container, unless you’ve specially configured the host.if finish than return true if fail clickĬonst dm = document.querySelector('downloads-manager').shadowRootĬonst firstItem = dm.querySelector('#frb0')Ĭonst thatArea = ('.controls') monitoring the state of the first download item
But you can easily adapt it to 'infinite threads' by iterating through all download items ( #frb0~ #frbn) in that page, well, take care of your network:) dmPage = await browser.newPage()Īwait your_download_button.click() // start downloadĪwait dmPage.bringToFront() // this is necessary This example is 'single thread' currently, because it's only monitoring the first item appear in the download manager page. This solution can be very easily to auto restart a failed download using chrome's own feature My solution is to use chrome's own chrome://downloads/ page to managing download files. It also has 'smarter' locator, which examine selectors every time before click() Use Playwright to get away from this mass.
