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

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.
```yaml
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](https://github.com/m1k1o/neko/blob/master/.docker/firefox/policies.json) file, modify and mount it as: ` -v '${PWD}/policies.json:/usr/lib/firefox/distribution/policies.json'`
- For Chromium, copy [this](https://github.com/m1k1o/neko/blob/master/.docker/chromium/policies.json) file, modify and mount it as: ` -v '${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 perspective, browser is not enabled to access local file data.
- If you want to enable this, you need to modify following policies:
```json
"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 perspective, browser is set up to forget all cookies and browsing history when its closed.
- If you want to enable this, you need to modify following policies:
```json
"DefaultCookiesSetting": 1,
"RestoreOnStartup": 1,
```
### Want to use VPN for your n.eko browsing?
- Check this out: https://github.com/m1k1o/neko-vpn
### Want to have multiple rooms on demand?
- Check this out: https://github.com/m1k1o/neko-rooms
### Want to use different Apps than Browser?
- Check this out: https://github.com/m1k1o/neko-apps
### 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.
