The noVNC view hung on "Connecting" forever then timed out. Root cause: x11vnc sweeps the entire fd table (fcntl per fd) on every client connection, and containerd grants pods RLIMIT_NOFILE=2^31, so the RFB handshake never completes (websockify accepts the WS and dials localhost:5900, but x11vnc never sends its banner — verified: handshake timed out at 8s, x11vnc had burned 1h41m CPU spinning). Same bug + fix the android-emulator stack already carries. Cap nofile before x11vnc starts, in two places: - files/novnc/entrypoint.sh: `ulimit -n 65536` (root fix, makes the image correct) - main.tf novnc container: `command = ["bash","-c","ulimit -n 65536; exec /entrypoint.sh"]` so the cap applies deterministically on rollout even though the image is :latest/IfNotPresent (a rebuilt entrypoint isn't guaranteed to be re-pulled). Also documents the gotcha + diagnosis in docs/architecture/chrome-service.md and notes the black-when-idle behaviour + the autoconnect URL. (A live x11vnc relaunch with the cap already unblocked the running pod; this makes it survive restarts.) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |
