I am in the process of creating an API utilizing Puppeteer within a Docker environment running on the node:18-alpine image. I have encountered a challenge where certain links cause Chromium to display an ‘xdg-open’ popup, which I am unable to suppress or manage programmatically. This popup prompts users to launch an external application, disrupting the automation workflow I am aiming for with Puppeteer.
My Attempts to Resolve This:
- Removing xdg-utils: I tried uninstalling xdg-utils from the container in hopes of stopping the popup, but it persisted.
- Investigating Chromium Flags: I searched for any flags that could prevent requests to external applications, yet I found no solutions that specifically tackle the ‘xdg-open’ issue.
- Adjusting Puppeteer Settings: I experimented with various launch configurations like --no-sandbox, --disable-popup-blocking, and --disable-dev-shm-usage, but none of these adjustments affected the xdg-open popup.
Solution to Suppress 'xdg-open' Popup in Puppeteer on Alpine Linux
Hi CharlieLion22,
Suppressing the 'xdg-open' popup while using Puppeteer within a Docker environment requires a tweak in how you handle external applications in Chromium. Here’s a practical approach:
Possible Solution
- Launch Configuration Modifications: Add a startup flag to disable external protocol handling in Chromium.
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch({
headless: true,
args: [
'--no-sandbox',
'--disable-setuid-sandbox',
'--disable-popup-blocking',
'--disable-external-protocol-handling'
],
});
const page = await browser.newPage();
// Your automation code
})();
- Ensure Container Cleanliness: Verify that your Docker container is utilizing the
node:18-alpine image without remnants of previous installations of xdg-utils that might affect execution. Clear any cached layers or rebuild the image.
- Alternative Chromium Flags: If the above does not work, try experimenting with other Chromium flags such as
--disable-background-networking and --disable-default-apps for better isolation of Chromium from external apps.
These changes should generally keep the popup from disrupting your workflow, allowing Puppeteer to operate smoothly within your Docker setup. Let me know how it goes!

Alternative Approach to Prevent 'xdg-open' Popup in Puppeteer on Alpine Linux
CharlieLion22,
Addressing the 'xdg-open' popup in a Puppeteer environment, especially within a Docker container, usually involves more than just a single solution. If the existing suggestions haven’t entirely worked, here's another pathway you might consider:
Advanced Method with Network Interception
- Network Handling: Use Puppeteer’s network interception feature to block requests that could trigger external application prompts. This method offers more direct control over how specific URLs are handled.
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch({
headless: true,
args: [
'--no-sandbox',
'--disable-setuid-sandbox'
],
});
const page = await browser.newPage();
await page.setRequestInterception(true);
page.on('request', request => {
// Block specific URLs that attempt to open external apps
if (request.url().startsWith('http://example-to-block.com')) {
request.abort();
} else {
request.continue();
}
});
// Further automation code
})();
- Docker Layer Strategy: Consider cleaning up your Docker build to ensure all previous caches, possibly affecting behavior, are removed. You can use
docker system prune to clear unused data.
- Security Configuration: If your web pages contribute to unpredictable requests, it's safer to sanitize inputs and control which domains are accessible during Puppeteer's session.
Applying these methods adds an additional layer of control to prevent interference from external application handlers, making Puppeteer automation more stable.
Best of luck with your development efforts!
Hey CharlieLion22,
To tackle the 'xdg-open' popup in Puppeteer within a Docker environment on Alpine Linux, try this:
Recommended Solution
- Use Chromium Flags: Add the
--disable-external-protocol-handling flag when launching Puppeteer to prevent the popup.
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch({
headless: true,
args: [
'--no-sandbox',
'--disable-setuid-sandbox',
'--disable-popup-blocking',
'--disable-external-protocol-handling'
],
});
const page = await browser.newPage();
// Your automation code
})();
Additionally, ensure your Docker image is clean from cached layers by rebuilding it periodically.
Hope this solves your issue!
Direct Approach to Handling 'xdg-open' Popup in Puppeteer on Alpine Linux
Hi CharlieLion22,
To efficiently deal with the 'xdg-open' popup while using Puppeteer in a Docker environment based on node:18-alpine, you should consider a blend of Chromium flags and network interceptions. Here is a streamlined solution:
Suggested Solution
- Disable External Handling via Chromium Flags: Utilize the
--disable-external-protocol-handling flag to suppress popups.
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch({
headless: true,
args: [
'--no-sandbox',
'--disable-setuid-sandbox',
'--disable-popup-blocking',
'--disable-external-protocol-handling'
],
});
const page = await browser.newPage();
// Your automation code
})();
- Network Interception for Precise Control: Implement request interception in Puppeteer to block specific URLs attempting to open external applications.
await page.setRequestInterception(true);
page.on('request', request => {
if (request.url().includes('unwanted-url.com')) {
request.abort();
} else {
request.continue();
}
});
These steps should reduce disruptions in your automation workflow within a Docker setup using Puppeteer. Ensure you periodically rebuild your Docker image by purging cached layers to maintain a clean environment.
Best,
David Grant
