Getting started & FAQ

Use the following docker images from Docker Hub for x86_64:

  • m1k1o/neko:latest or m1k1o/neko:firefox - for Firefox.
  • m1k1o/neko:chromium - for Chromium (needs --cap-add=SYS_ADMIN, see the security implications).
  • m1k1o/neko:google-chrome - for Google Chrome (needs --cap-add=SYS_ADMIN, see the security implications).
  • m1k1o/neko:ungoogled-chromium - for Ungoogled Chromium (needs --cap-add=SYS_ADMIN, see the security implications) (by @whalehub).
  • m1k1o/neko:microsoft-edge - for Microsoft Edge (needs --cap-add=SYS_ADMIN, see the security implications).
  • m1k1o/neko:brave - for Brave Browser (needs --cap-add=SYS_ADMIN, see the security implications).
  • m1k1o/neko:vivaldi - for Vivaldi Browser (needs --cap-add=SYS_ADMIN, see the security implications) (by @Xeddius).
  • m1k1o/neko:opera for Opera Browser (requires extra steps to enable DRM, see instructions here. libffmpeg is already configured.) (by @prophetofxenu)
  • m1k1o/neko:tor-browser - for Tor Browser.
  • m1k1o/neko:remmina - for remote desktop connection (by @lowne).
    • Pass env var REMMINA_URL=<proto>://[<username>[:<password>]@]server[:port] (proto being vnc, rdp or spice).
    • Or create your custom configuration with remmina locally (it's saved in ~/.local/share/remmina/path_to_profile.remmina) and bind-mount it, then pass env var REMMINA_PROFILE=<path_to_profile.remmina>.
  • m1k1o/neko:vlc - for VLC Video player (needs volume mounted to /media with local video files, or setting VLC_MEDIA=/media path).
  • m1k1o/neko:xfce - for a shared desktop / installing shared software.
  • m1k1o/neko:base - for custom base.

Dockerhub images are built using GitHub actions on every push and on weekly basis to keep all browsers up-to-date.

All images are also available on GitHub Container Registry for faster pulls:

  • ghcr.io/m1k1o/neko/firefox:latest
  • ghcr.io/m1k1o/neko/chromium:latest
  • ghcr.io/m1k1o/neko/google-chrome:latest
  • ghcr.io/m1k1o/neko/ungoogled-chromium:latest
  • ghcr.io/m1k1o/neko/microsoft-edge:latest
  • ghcr.io/m1k1o/neko/brave:latest
  • ghcr.io/m1k1o/neko/vivaldi:latest
  • ghcr.io/m1k1o/neko/opera:latest
  • ghcr.io/m1k1o/neko/tor-browser:latest
  • ghcr.io/m1k1o/neko/remmina:latest
  • ghcr.io/m1k1o/neko/vlc:latest
  • ghcr.io/m1k1o/neko/xfce:latest

For ARM-based images (like Raspberry Pi - with GPU hardware acceleration, Oracle Cloud ARM tier). Currently not all images are available for ARM, because not all applications are available for ARM.

  • ghcr.io/m1k1o/neko/arm-firefox:latest
  • ghcr.io/m1k1o/neko/arm-chromium:latest
  • ghcr.io/m1k1o/neko/arm-ungoogled-chromium:latest
  • ghcr.io/m1k1o/neko/arm-vlc:latest
  • ghcr.io/m1k1o/neko/arm-xfce:latest

For images with VAAPI GPU hardware acceleration using intel drivers use:

  • ghcr.io/m1k1o/neko/intel-firefox:latest
  • ghcr.io/m1k1o/neko/intel-chromium:latest
  • ghcr.io/m1k1o/neko/intel-google-chrome:latest
  • ghcr.io/m1k1o/neko/intel-ungoogled-chromium:latest
  • ghcr.io/m1k1o/neko/intel-microsoft-edge:latest
  • ghcr.io/m1k1o/neko/intel-brave:latest
  • ghcr.io/m1k1o/neko/intel-vivaldi:latest
  • ghcr.io/m1k1o/neko/intel-opera:latest
  • ghcr.io/m1k1o/neko/intel-tor-browser:latest
  • ghcr.io/m1k1o/neko/intel-remmina:latest
  • ghcr.io/m1k1o/neko/intel-vlc:latest
  • ghcr.io/m1k1o/neko/intel-xfce:latest

GHCR images are built using GitHub actions for every tag.

Networking:

  • If you want to use n.eko in external network, you can omit NEKO_NAT1TO1. It will automatically get your Public IP.
  • If you want to use n.eko in internal network, set NEKO_NAT1TO1 to your local IP address (e.g. NEKO_NAT1TO1: 192.168.1.20)-
  • Currently, it is not supported to supply multiple NAT addresses (see https://github.com/m1k1o/neko/issues/47).

Why so many ports?

  • WebRTC needs UDP ports in order to transfer Audio/Video towards user and Mouse/Keyboard events to the server in real time.
  • If you don't set NEKO_ICELITE=true, every user will need 2 UDP ports.
  • If you set NEKO_ICELITE=true, every user will need only 1 UDP port. It is recommended to use ice-lite.
  • Do not forget, they are UDP ports, that configuration must be correct in your firewall/router/docker.
  • You can freely limit number of UDP ports. But you can't map them to different ports.
    • This WON'T work: 32000-32100:52000-52100/udp
  • You can change API port (8080).
    • This WILL work: 3000:8080

Using mux instead of epr

When using a mux, not so many ports are needed.

version: "3.4"
services:
  neko:
    image: "m1k1o/neko:firefox"
    restart: "unless-stopped"
    shm_size: "2gb"
    ports:
      - "8080:8080"
      - "8081:8081/tcp"
      - "8082:8082/udp"
    environment:
      NEKO_SCREEN: 1920x1080@30
      NEKO_PASSWORD: neko
      NEKO_PASSWORD_ADMIN: admin
      NEKO_TCPMUX: 8081
      NEKO_UDPMUX: 8082
      NEKO_ICELITE: 1
  • When using mux, NEKO_EPR is ignored.
  • Mux accepts only one port, not a range.
  • You only need to expose maximum two ports for WebRTC on your router/firewall and have many users connected.
  • It can even be the same port number, so e.g. NEKO_TCPMUX: 8081 and NEKO_UDPMUX: 8081.
  • The same port must be exposed from docker container, you can't map them to different ports. So 8082:8082 is OK, but "5454:8082 will not work.
  • You can use them alone (either TCP or UDP) when needed.
    • UDP is generally better for latency. But some networks block UDP so it is good to have TCP available as fallback.
  • Still, using NEKO_ICELITE=true is recommended.

Want to customize and install own add-ons, set custom bookmarks?

  • You would need to modify the existing policy file and mount it to your container.
  • For Firefox, copy this file, modify and mount it as: -v '${PWD}/policies.json:/usr/lib/firefox/distribution/policies.json'
  • For Chromium, copy this file, modify and mount it as: -v '${PWD}/policies.json:/etc/chromium/policies/managed/policies.json'
  • For others, see where existing policies.json is placed in their Dockerfile.

Allow file uploading & downloading

  • From security perespective, browser is not enabled to access local file data.
  • If you want to enable this, you need to modify following policies:
  "DownloadRestrictions": 0,
  "AllowFileSelectionDialogs": true,
  "URLAllowlist": [
      "file:///home/neko/Downloads"
  ],

Want to preserve browser data between restarts?

  • You need to mount browser profile as volume.
  • For Firefox, that is this /home/neko/.mozilla/firefox/profile.default folder, mount it as: -v '${PWD}/data:/home/neko/.mozilla/firefox/profile.default'
  • For Chromium, that is this /home/neko/.config/chromium folder, mount it as: -v '${PWD}/data:/home/neko/.config/chromium'
  • For other chromium based browsers, see in supervisord.conf folder that is specified in --user-data-dir.

Allow persistent data in policies

  • From security perespective, browser is set up to forget all cookies and brwosing history when its closed.
  • If you want to enable this, you need to modify following policies:
  "DefaultCookiesSetting": 1,
  "RestoreOnStartup": 1,

Want to use VPN for your n.eko browsing?

Want to have multiple rooms on demand?

Want to use different Apps than Browser?

Accounts:

  • There are no accounts, display name (a.k.a. username) can be freely chosen. Only password needs to match. Depending on which password matches, the visitor gets its privilege:
    • Anyone, who enters with NEKO_PASSWORD will be user.
    • Anyone, who enters with NEKO_PASSWORD_ADMIN will be admin.
  • Disabling passwords is not possible. However, you can use following query parameters to create auto-join links:
    • Adding ?pwd=<password> will prefill password.
    • Adding ?usr=<display-name> will prefill username.
    • Adding ?cast=1 will hide all control and show only video.
    • e.g. http(s)://<URL:Port>/?pwd=neko&usr=guest&cast=1

Screen size

  • Only admins can change screen size.
  • You can set a default screen size, but this size MUST be one from the list, that your server supports.
  • You will get this list in frontend, where you can choose from.

Clipboard sharing

  • Browsers have certain requirements to allow clipboard sharing.
    • Your instance must be HTTPS.
    • Firefox does not support clipboard sharing.
    • Use Chrome for the best experience.
  • If your browser does not support clipboard sharing:
    • Clipboard icon in the bottom right corner will be displayed for host.
    • It opens text area that can share clipboard content bi-directionally.
    • Only plain-text is supported.
