How to Fix Browser Crashed in Docker Containers

Learn how to diagnose and resolve browser crashed when running Playwright tests in docker containers.

Encountering browser-crashed in docker-containers is a common hurdle for engineering teams. This guide provides a surgical approach to fixing the issue and ensuring your monitoring is resilient.

Quick Fix Steps

  1. Verify Network Connectivity: Ensure docker-containers has access to the target URL.
  2. Increase Navigation Timeout: Add page.setDefaultNavigationTimeout(60000).
  3. Check Resource Limits: Increase memory/CPU if running in Docker or CI.

Playwright Debugging Script

import { test, expect } from '@playwright/test';

test('debug browser-crashed in docker-containers', async ({ page }) => {
  // Set explicit timeouts for debugging
  page.setDefaultTimeout(45000);
  
  try {
    await page.goto('https://your-app.com', { waitUntil: 'networkidle' });
    // Add logic to trigger the error
  } catch (error) {
    console.error('Captured Error in docker-containers:', error.message);
    throw error;
  }
});

Solving the Maintenance Tax with supaguard

Instead of manually debugging browser-crashed every time your CI environment changes, supaguard automates the recovery.

AI-Native RCA

Our Sanctum AI analyzes the execution trace and provides a human-readable explanation of why browser-crashed occurred in docker-containers.

Automatic Region Verification

If a check fails in one region, supaguard automatically retries from another to confirm if the issue is global or specific to the docker-containers network.
