Bash alias:
alias yt-dlp='export USER_ID=$(id -u) && export GROUP_ID=$(id -g) && docker compose -f /path/to/repo/yt-dlp-docker/docker-compose.yml run --rm app'
The user ID and group ID are applied to the downloaded file.
docker compose build
By default, yt-dlp will be updated to the nightly channel. You can override this with the build arg CHANNEL.
