It’s my first time trying to selfhost things for myself, and among one of those services I want to host is Fireshare, but I just can’t make it work and I don’t know how to make it work.

First of all, I’m a complete noob and I barely have experience with Linux, I’m a complete ignorant on servers.

I honestly don’t understand how to install it in the first place, and I’ve already seen the Docker installation command.

docker run --name fireshare -v $(pwd)/fireshare:/data:rw -v $(pwd)/fireshare_processed:/processed:rw -v /path/to/my_game_clips:/videos:rw -p 8080:80 -e ADMIN_PASSWORD=your-admin-password -d shaneisrael/fireshare:latest

When I try to run that command and change the directory of the clips, and the administrator password the only thing I get is a Docker error saying:

docker: Error response from daemon: pull access denied for 8080, repository does not exist or may require ‘docker login’: denied: requested access to the resource is denied.

And besides, already host Owncast at port 8080, can’t I use another port?
