SeleniumBase Docker Image Guide: Fix Environment Issues & Integrate Proxies Easily

If you’ve ever dabbled in Web automation or scraping, you know the two biggest nightmares: inconsistent environments (“It works on my machine, but not the server!”) and sudden IP bans from anti – bot systems. Spending hours debugging environment dependencies or reconfiguring browsers across devices kills productivity. And when your automation script gets blocked mid – task due to IP restrictions, all that effort goes down the drain.

Enter SeleniumBase Docker Image—a game – changer for Web automation. By packaging SeleniumBase (the powerful Python automation framework) into a Docker container, it ensures your scripts run consistently across any environment. No more installing browsers, drivers, or dependencies manually. But to truly unlock its potential and avoid IP bans, you need a reliable proxy solution. That’s where IPFLY comes in. With its no – client design, IPFLY integrates seamlessly with SeleniumBase Docker, no extra software installation required—keeping your container lightweight and your automation smooth.

In this guide, we’ll cover everything you need to master SeleniumBase Docker Image: what it is, why it’s a must – have for automation, step – by – step setup (with code blocks), how to integrate IPFLY proxy to avoid IP bans, troubleshooting common issues, and a comparison of proxy solutions. Whether you’re a tester, scraper, or RPA developer, this guide will help you build stable, scalable automation workflows.

What Is SeleniumBase Docker Image & Why You Need It

First, let’s break down the basics. SeleniumBase is a high – level Python framework built on Selenium, packed with features like smart waits, automatic screenshots, test reporting, and anti – crawl capabilities (UC/CDP mode). Docker, on the other hand, is a containerization platform that packages applications and their dependencies into isolated containers, ensuring consistent performance across environments.

SeleniumBase Docker Image combines these two tools: it’s a pre – built Docker image that includes SeleniumBase, all required browsers (Chrome, Firefox), Web drivers, and dependencies. Here’s why it’s indispensable for automation:

Eliminate Environment Inconsistencies

No more “it works on my machine” issues. The Docker image ensures the same browser versions, drivers, and framework setups on your local machine, server, or cloud platform. Your automation scripts will run identically everywhere.

Save Hours of Setup Time

Forget manually installing Chrome, chromedriver, Python packages, or configuring environment variables. Just pull the SeleniumBase Docker image and start running scripts in minutes.

Lightweight & Scalable

Docker containers are lightweight compared to virtual machines. You can spin up multiple SeleniumBase containers to run tests or scrapers in parallel, drastically reducing execution time.

Built – in Anti – Crawl Support

SeleniumBase’s UC mode (Undetected ChromeDriver) is included, which mimics real user browser fingerprints to bypass basic anti – bot systems. Pair it with a proxy like IPFLY, and you’ll breeze through most anti – crawl measures.

Step – by – Step: Set Up & Use SeleniumBase Docker Image

Let’s get hands – on with SeleniumBase Docker Image. We’ll cover the core steps: installing Docker, pulling/building the image, running a test script, and verifying the setup.

Prerequisite: Install Docker

First, install Docker Desktop (for Windows/macOS) or Docker Engine (for Linux) from the official Docker website. Verify the installation by running this command in your terminal:

docker --version

You should see the Docker version printed if the installation is successful.

Pull or Build the SeleniumBase Docker Image

You have two options: pull the official pre – built image or build it from the SeleniumBase Dockerfile. For most users, pulling the official image is faster:

Option 1: Pull the Official Image (Recommended)

# Pull the latest SeleniumBase Docker image
docker pull seleniumbase/seleniumbase

Option 2: Build from Dockerfile (For Customization)

If you need custom configurations (e.g., additional packages), clone the SeleniumBase repo and build the image:

# Clone the SeleniumBase repository
git clone https://github.com/seleniumbase/SeleniumBase.git
cd SeleniumBase

# Build the image (adjust platform for Apple Silicon Macs)
# For Windows/Linux/Intel Macs
docker build -t seleniumbase .

# For Apple Silicon Macs (enable Rosetta first in Docker Desktop)
export DOCKER_DEFAULT_PLATFORM=linux/amd64
docker build --platform linux/amd64 -t seleniumbase .

Run a Test Script in SeleniumBase Docker

Let’s run a simple test script to verify the setup. We’ll use SeleniumBase’s built – in example test that opens a browser and navigates to a page:

# Run the example Chrome test in the Docker container
docker run seleniumbase ./run_docker_test_in_chrome.sh

If successful, the container will start Chrome, run the test, and exit automatically. You can also enter the container interactively to run custom scripts:

# Enter the Docker container shell
docker run -i -t seleniumbase

# Run your custom test script from inside the container
pytest your_test_script.py -s

Create a Custom Automation Script

Let’s create a simple custom script for Web scraping. Create a file namedscrape_example.py with the following code:

from seleniumbase import BaseCase

class ScrapeTest(BaseCase):
    def test_scrape_example(self):
        # Enable UC mode to bypass basic anti - bot systems
        self.set_uc_mode(True)
        # Open the target page
        self.open("https://example.com")
        # Scrape page title
        page_title = self.get_title()
        print(f"Page Title: {page_title}")
        # Save a screenshot
        self.save_screenshot("scrape_result.png")

To run this script in the Docker container, mount your local directory to the container’s /app folder:

# Run custom script (replace /path/to/your/scripts with your local script directory)
docker run -v /path/to/your/scripts:/app seleniumbase pytest /app/scrape_example.py --uc -s

The -v flag mounts your local directory to the container, so the script and screenshot are accessible on your local machine.

Critical for Automation: Integrate Proxy with SeleniumBase Docker

When running Web scraping or large – scale automation, IP bans are inevitable. A proxy hides your real IP address, allowing you to continue operations. However, proxy integration with SeleniumBase Docker can be tricky—common issues include authentication pop – ups, incompatible modes, and complex client installations. This is where IPFLY’s no – client proxy solution shines.

Why Proxies Fail in SeleniumBase Docker (Common Pitfalls)

Based on real – world issues from developers, here are the top proxy integration problems in SeleniumBase Docker:

• Authentication Pop – Ups: Chrome doesn’t natively support authenticated SOCKS5 proxies, leading to annoying login prompts that break automation.
• UC/CDP Mode Incompatibility: Using proxies with SeleniumBase’s UC mode (for anti – crawl) often causes “session not created” errors in Docker.
• Client Bloat: Proxy services like Bright Data require installing a client application, which adds layers to the Docker container and increases complexity.
• Environment Variable Issues: Passing proxy credentials via environment variables may not work as expected, leading to unauthenticated requests.

IPFLY: The No – Client Proxy Solution for SeleniumBase Docker

IPFLY solves these problems with its no – client design—no need to install any extra software in the Docker container. You can configure it directly via SeleniumBase’s proxy parameters, keeping your setup lightweight and error – free. Here’s why IPFLY is the best fit for SeleniumBase Docker:

No – Client Design = Seamless Docker Integration

Unlike Bright Data (requires Proxy Manager client) or Oxylabs (needs API client deployment), IPFLY works with SeleniumBase’s native proxy configuration. Just pass the IPFLY proxy details via CLI or code—no client installation, no container bloat.

99.9% Uptime = Uninterrupted Automation

IPFLY’s self – built global residential IP network and BGP multi – line redundancy ensure 99.9% uptime. For long – running automation tasks (e.g., 24/7 scraping), this means no unexpected proxy downtime that breaks your scripts.

Authenticated Proxy Support = No Pop – Ups

IPFLY’s proxy URL format (including username and password) is fully compatible with SeleniumBase’s latest versions, avoiding authentication pop – ups. It works seamlessly with both regular and UC modes (when configured correctly).

Step – by – Step: Integrate IPFLY with SeleniumBase Docker

Follow these steps to configure IPFLY proxy in your SeleniumBase Docker workflow:

Step 1: Get IPFLY Proxy Details

Log into your IPFLY account, generate a residential proxy, and note the following details: socks5://username:password@proxy-ip:port (SOCKS5 is recommended for better compatibility).

Step 2: Configure Proxy in SeleniumBase Docker (Two Methods)

Method 1: Pass Proxy via CLI Command

Run your script with the --proxy flag to pass the IPFLY proxy:

# Run custom script with IPFLY proxy (mount local directory)
docker run -v /path/to/your/scripts:/app seleniumbase pytest /app/scrape_example.py --uc --proxy="socks5://username:password@proxy-ip:port" -s

Method 2: Embed Proxy in the Script

For more control, set the proxy directly in your Python script. Update your scrape_example.py:

from seleniumbase import BaseCase

class ScrapeTest(BaseCase):
    def test_scrape_example(self):
        # Configure IPFLY proxy
        ipfly_proxy = "socks5://username:password@proxy-ip:port"
        self.set_uc_mode(True)
        # Set proxy (works for both regular and UC modes)
        self.driver.execute_cdp_cmd(
            "Network.setProxy",
            {
                "proxyServer": ipfly_proxy.replace("socks5://", ""),
                "proxyBypassList": "localhost,127.0.0.1"
            }
        )
        # Open the target page
        self.open("https://example.com")
        # Verify proxy IP (scrape public IP)
        self.open("https://api.ipify.org")
        proxy_ip = self.get_text("body")
        print(f"Current Proxy IP: {proxy_ip}")
        # Save screenshot
        self.save_screenshot("ipfly_proxy_result.png")

Run the updated script in Docker as before—no extra configuration needed.

Step 3: Verify Proxy Workflow

After running the script, check the ipfly_proxy_result.png screenshot and terminal output. The printed IP should match your IPFLY proxy IP, confirming the integration is successful.

Troubleshooting Common SeleniumBase Docker Issues

Even with the right setup, you may encounter issues. Here are solutions to the most common problems:

“Session Not Created” Error in UC Mode

Solution: Docker leaves a unique fingerprint that conflicts with UC mode’s anti – detection features. For critical anti – crawl tasks, use IPFLY’s residential proxies and avoid UC mode in Docker (use regular Ubuntu for UC mode). If you must use UC mode in Docker, add the --xvfb flag to run headless and reduce fingerprinting:

docker run -v /path/to/scripts:/app seleniumbase pytest /app/scrape_example.py --uc --xvfb --proxy="ipfly-proxy-url" -s

Chrome Crashes on Apple Silicon Macs

Solution: Enable Rosetta in Docker Desktop first, then build the image with the --platform linux/amd64 flag (as shown in Section 2.2).

Proxy Authentication Pop – Ups

Solution: Use IPFLY’s SOCKS5 proxy URL with embedded credentials (e.g., socks5://user:pass@ip:port) and ensure you’re using the latest version of SeleniumBase. Chrome’s native limitation on authenticated proxies is bypassed by SeleniumBase’s CDP command integration (as in IPFLY’s script example).

Can’t Find Local Scripts in Docker

Solution: Double – check the -v mount path. Ensure the local directory path (e.g., /path/to/your/scripts) is absolute, not relative. On Windows, use paths like C:/Users/YourName/scripts.
