This container is build to my preference but you can feel free to fork and modify all you want.
Copy the neovim shell script from in the container to anywhere on your $PATH.
docker run -it --rm fxdgear/alpine-neovim:latest cat /neovim | sed -e 's/\r//' > /usr/local/bin/nvim && chmod +x /usr/local/bin/nvimnow just run the command nvim.
