# how to host a cobalt instance yourself
|
||
## using docker compose and package from github (recommended)
|
||
to run the cobalt docker package, you need to have `docker` and `docker-compose` installed and configured.
|
||
|
||
if you need help with installing docker, follow *only the first step* of these tutorials by digitalocean:
|
||
- [how to install docker](https://www.digitalocean.com/community/tutorial-collections/how-to-install-and-use-docker)
|
||
- [how to install docker compose](https://www.digitalocean.com/community/tutorial-collections/how-to-install-docker-compose)
|
||
|
||
## how to run a cobalt docker package:
|
||
1. create a folder for cobalt config file, something like this:
|
||
```sh
|
||
mkdir cobalt
|
||
```
|
||
|
||
2. go to cobalt folder, and create a docker compose config file:
|
||
```sh
|
||
cd cobalt && nano docker-compose.yml
|
||
```
|
||
i'm using `nano` in this example, it may not be available in your distro. you can use any other text editor.
|
||
|
||
3. copy and paste the [sample config from here](examples/docker-compose.example.yml) for either web or api instance (or both, if you wish) and edit it to your needs.
|
||
make sure to replace default URLs with your own or cobalt won't work correctly.
|
||
|
||
4. finally, start the cobalt container (from cobalt directory):
|
||
```sh
|
||
docker compose up -d
|
||
```
|
||
|
||
if you want your instance to support services that require authentication to view public content, create `cookies.json` file in the same directory as `docker-compose.yml`. example cookies file [can be found here](examples/cookies.example.json).
|
||
|
||
cobalt package will update automatically thanks to watchtower.
|
||
|
||
it's highly recommended to use a reverse proxy (such as nginx) if you want your instance to face the public internet. look up tutorials online.
|
||
|
||
## using regular node.js (useful for local development)
|
||
setup script installs all needed `npm` dependencies, but you have to install `node.js` *(version 18 or above)* and `git` yourself.
|
||
|
||
1. clone the repo: `git clone https://github.com/wukko/cobalt`.
|
||
2. run setup script and follow instructions: `npm run setup`. you need to host api and web instances separately, so pick whichever applies.
|
||
3. run cobalt via `npm start`.
|
||
4. done.
|
||
|
||
### ubuntu 22.04 workaround
|
||
`nscd` needs to be installed and running so that the `ffmpeg-static` binary can resolve DNS ([#101](https://github.com/wukko/cobalt/issues/101#issuecomment-1494822258)):
|
||
|
||
```bash
|
||
sudo apt install nscd
|
||
sudo service nscd start
|
||
```
|
||
|
||
## list of all environment variables
|
||
### variables for api
|
||
| variable name | default | example | description |
|
||
|:----------------------|:----------|:------------------------|:------------|
|
||
| `API_PORT` | `9000` | `9000` | changes port from which api server is accessible. |
|
||
| `API_LISTEN_ADDRESS` | `0.0.0.0` | `127.0.0.1` | changes address from which api server is accessible. **if you are using docker, you usually don't need to configure this.** |
|
||
| `API_URL` | ➖ | `https://co.wuk.sh/` | changes url from which api server is accessible. <br> ***REQUIRED TO RUN API***. |
|
||
| `API_NAME` | `unknown` | `ams-1` | api server name that is shown in `/api/serverInfo`. |
|
||
| `CORS_WILDCARD` | `1` | `0` | toggles cross-origin resource sharing. <br> `0`: disabled. `1`: enabled. |
|
||
| `CORS_URL` | not used | `https://cobalt.tools/` | cross-origin resource sharing url. api will be available only from this url if `CORS_WILDCARD` is set to `0`. |
|
||
| `COOKIE_PATH` | not used | `/cookies.json` | path for cookie file relative to main folder. |
|
||
| `PROCESSING_PRIORITY` | not used | `10` | changes `nice` value* for ffmpeg subprocess. available only on unix systems. |
|
||
| `TIKTOK_DEVICE_INFO` | ➖ | *see below* | device info (including `iid` and `device_id`) for tiktok functionality. required for tiktok to work. |
|
||
| `FREEBIND_CIDR` | ➖ | `2001:db8::/32` | IPv6 prefix used for randomly assigning addresses to cobalt requests. only supported on linux systems. for more info, see below. |
|
||
|
||
\* the higher the nice value, the lower the priority. [read more here](https://en.wikipedia.org/wiki/Nice_(Unix)).
|
||
|
||
#### TIKTOK_DEVICE_INFO
|
||
you need to get your own device info for tiktok functionality to work. this can be done by proxying the app through any request-intercepting proxy (such as [mitmproxy](https://mitmproxy.org)). you need to disable ssl pinning to see requests. there will be no assistance provided by cobalt for this.
|
||
|
||
example config (replace **ALL** values with ones you got from mitm):
|
||
```
|
||
'{
|
||
"iid": "<install_id here>",
|
||
"device_id": "<device_id here>",
|
||
"channel": "googleplay",
|
||
"app_name": "musical_ly",
|
||
"version_code": "310503",
|
||
"device_platform": "android",
|
||
"device_type": "Redmi+7",
|
||
"os_version": "13"
|
||
}'
|
||
```
|
||
|
||
you can compress the json to save space. if you're using a `.env` file then the line would would look like this (***note the quotes***):
|
||
```
|
||
TIKTOK_DEVICE_INFO='{"iid":"<install_id here>","device_id":"<device_id here>","channel":"googleplay","app_name":"musical_ly","version_code":"310503","device_platform":"android","device_type":"Redmi+7","os_version":"13"}'
|
||
```
|
||
|
||
#### FREEBIND_CIDR
|
||
setting a `FREEBIND_CIDR` allows cobalt to pick a random IP for every download and use it for all
|
||
requests it makes for that particular download. to use freebind in cobalt, you need to follow its [setup instructions](https://github.com/imputnet/freebind.js?tab=readme-ov-file#setup) first. if you configure this option while running cobalt
|
||
in a docker container, you also need to set the `API_LISTEN_ADDRESS` env to `127.0.0.1`, and set
|
||
`network_mode` for the container to `host`.
|
||
|
||
### variables for web
|
||
| variable name | default | example | description |
|
||
|:---------------------|:---------------------|:------------------------|:--------------------------------------------------------------------------------------|
|
||
| `WEB_PORT` | `9001` | `9001` | changes port from which frontend server is accessible. |
|
||
| `WEB_URL` | ➖ | `https://cobalt.tools/` | changes url from which frontend server is accessible. <br> ***REQUIRED TO RUN WEB***. |
|
||
| `API_URL` | `https://co.wuk.sh/` | `https://co.wuk.sh/` | changes url which is used for api requests by frontend clients. |
|
||
| `SHOW_SPONSORS` | `0` | `1` | toggles sponsor list in about popup. <br> `0`: disabled. `1`: enabled. |
|
||
| `IS_BETA` | `0` | `1` | toggles beta tag next to cobalt logo. <br> `0`: disabled. `1`: enabled. |
|
||
| `PLAUSIBLE_HOSTNAME` | ➖ | `plausible.io`* | enables plausible analytics with provided hostname as receiver backend. |
|
||
|
||
\* don't use plausible.io as receiver backend unless you paid for their cloud service. use your own domain when hosting community edition of plausible. refer to their [docs](https://plausible.io/docs) when needed.
