# netvm-chrome.sh [--headless] [--cdp-port N|--no-cdp] [--contained] <profile> [url]

# Launch a chrome-box profile inside its dedicated NetVM netns.
|
|
# 1:1: profile = node = warp identity = egress IP.
|
|
# CDP is on by default (deterministic port) so agents can automate the
|
|
# session via Playwright/Puppeteer; --headless runs without a display.
|
|
# --contained adds a bwrap filesystem jail INSIDE the netns (no net unshare):
|
|
# the browser sees only its own profile home (+ vault read-only). Chromium's
|
|
# own sandbox stays on (we never pass --no-sandbox to it).
|
|
# Run as your normal user (uses sudo -n only for allowlisted netns ops).
