There is no India-specific Selenium command: the important local factors are the server’s CPU architecture, resource limits, and whether the chosen browser image supports that architecture. Official Selenium materials do not establish a universal minimum RAM figure for a particular screenshot workload.
How do I run Selenium headless on a Linux server?
A standalone Selenium container is a practical starting point for a server because it packages the browser and exposes a WebDriver endpoint. Check the host and image compatibility first, then use a pinned full image tag rather than a floating latest tag. SeleniumHQ documents standalone Chrome and Firefox images; confirm the current tag and architecture support in the Docker Selenium README, since both change over time.
Check the server before choosing an image
- Record the Linux distribution and CPU architecture: typically
amd64/x86_64orarm64/aarch64. - Check physical or virtual memory limits, swap, available disk, and any container memory limits.
- Confirm that the exact Selenium browser image tag is published for the host architecture. Do not assume an amd64 image is available for ARM64; the project warns against AMD64 emulation on ARM64.
- For an India-hosted server, consider the location’s latency and your team’s data-residency and operational needs. Confirm provider region and terms directly; these vary by provider and are not determined by Selenium.
Start one pinned standalone browser
Replace the tag placeholder with a current, fully specified image tag supported on your architecture:
docker run --rm
--shm-size=2g
-p 4444:4444
selenium/standalone-chrome:<pinned-full-tag>SeleniumHQ documents --shm-size=2g as a known browser-container workaround, while describing it as an arbitrary value that may need tuning. It configures shared memory; it does not mean the host needs exactly 2 GB of total RAM, nor guarantee that the setting is optimal for your workload. See the current project guidance before deployment.

It also automatically finds and deletes similar or duplicate photo, backs up live photos and allows you to share them with your friends or family with just one tap. Everything stays effortlessly organized, powered by intelligent tagging and recognition.
Headless execution removes the need for a graphical display server in this setup. SeleniumHQ says a headless browser does not need Xvfb and documents SE_START_XVFB=false for disabling its startup. Follow the README’s version-specific Chrome instructions. Do not disable Xvfb unless the browser is actually launched headlessly; otherwise startup can fail. Headless mode is not a promise of negligible memory use or a fixed memory saving.
How can I take screenshots with Selenium in Python?
Install the Selenium Python client in the environment that runs your tests. Start the container above, then use Remote WebDriver at http://localhost:4444 if the Python process runs on the host. If it runs in another container, connect to the browser service by its reachable Docker network hostname; localhost would refer to the client container itself.
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("--headless")
driver = webdriver.Remote(
command_executor="http://localhost:4444",
options=options,
)
try:
driver.set_window_size(1365, 900)
driver.get("https://example.com")
# Add an application-specific readiness wait here when needed.
driver.save_screenshot("screenshot.png")
finally:
driver.quit()The screenshot API saves the current browser context to a file; Selenium also supports screenshots of an individual element. See the official Selenium interactions documentation. The example combines the documented screenshot and remote-session patterns; it is not a measured recipe for a specific server or package version.

For visual regression, choose a deliberate viewport and wait for the page state your test actually needs before capturing. Pages with delayed content, animations, or network-dependent elements may not be visually stable immediately after navigation. Always call quit(), including when a test raises an exception, so sessions do not linger.

How much RAM does Selenium need?
There is no established universal minimum for a server running a particular site or screenshot workload. Memory use depends on the browser, page and its assets, viewport, test actions, and number of concurrent sessions. The documented 2g shared-memory setting is not a total-RAM benchmark.
On a constrained host, begin with one session at a time and measure representative pages on the actual machine. Observe host memory, swap activity, CPU, container restarts, and free disk while tests run. Add parallel sessions only when the measured peak leaves enough headroom for the host and other services. If one session is unstable under representative load, investigate the page, limits, browser compatibility, and shared memory before adding concurrency.

Can I run Selenium in Docker on a VPS?
Yes, provided Docker is available and the selected image supports the VPS architecture. A single standalone browser container is simpler than introducing a multi-node Grid when only one session is needed. Keep image tags pinned for repeatability, and retain screenshots, logs, and other needed artifacts on a persistent mounted path if the runner container is disposable. Check file ownership and available disk space.
When parallel execution becomes necessary, compare its time savings against measured memory and CPU use. Selenium Grid has session and resource configuration controls, but a Hub/Node topology adds operational complexity; do not add it before there is a need for parallel sessions. The Grid configuration options describe available controls.

- Use a fully tagged Selenium image so the browser and Grid versions remain stable between runs.
- Match Chrome and ChromeDriver at the major-version level. Selenium’s Chrome documentation says Selenium 4 is compatible with Chrome v75 and newer; recheck current compatibility guidance as browser support evolves.
- Check the Selenium Grid UI on port 4444 or its
/statusendpoint. The Grid getting-started guide covers Remote WebDriver, the local endpoint, and health checks. - Use container logs and host monitoring together to distinguish browser startup errors, memory pressure, and test failures.
Why does Chrome crash in a Docker container?
Chrome exits or crashes
Check available host memory and container limits, Chrome/ChromeDriver compatibility, and shared-memory configuration. SeleniumHQ identifies --shm-size=2g as a known workaround for browser crashes, but calls the value arbitrary and advises tuning it for the use case. --disable-dev-shm-usage is not a universal memory fix: it changes where shared-memory files are used and can exchange one constraint for another.
The browser fails after Xvfb is disabled
Confirm that browser options really enable headless mode. Disabling the display server without running the browser headlessly can cause startup errors; consult the current Docker Selenium instructions for the image and browser version.
Tests become unstable when run together
Serialize the tests temporarily, check for leftover sessions, and monitor memory and CPU pressure. Restore concurrency only after measuring the target workload under the intended limits.
The image will not start on an ARM server
Inspect the project’s current architecture and browser matrix, then choose a tag published for that architecture. Do not assume emulation will have normal performance or stability; the project cautions against AMD64 emulation on ARM64.
