# 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](https://github.com/wukko/cobalt/blob/current/docs/examples/docker-compose.example.json) for either web or api instance (or both, if you wish) and edit it to your needs.
|
||
|
|
make sure to replace default URLs with yours or cobalt won't work correctly.
|
||
|
|
|
||
|
|
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 file for cookies file [can be found here](https://github.com/wukko/cobalt/blob/current/docs/examples/cookies.example.json).
|
||
|
|
|
||
|
|
cobalt package will automatically update itself 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 for that 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
|
||
|
|
```
