Getting started & FAQ

Use the following docker images:

• 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:tor-browser - for Tor Browser.
• m1k1o/neko:vncviewer - for simple VNC viewer (specify NEKO_VNC_URL to your VNC target).
• 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.

For ARM-based devices (like Raspberry Pi, with GPU hardware acceleration):

• m1k1o/neko:arm-firefox - for Firefox.
• m1k1o/neko:arm-chromium - for Chromium.
• m1k1o/neko:arm-base - for custom arm based.

Images (except arm-) are built using GitHub actions on every push and on weekly basis to keep all browsers up-to-date,

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

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.

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.

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.
