You must setup Podman and Lighttpd first.

Steps

  1. create nvim directory in $HOME/podman
    mkdir -p ~/podman/nvim && cd ~/podman/nvim
  2. copy from compose.yml
    nano compose.yml
  3. copy from nvim.conf
    nano ~/lighttpd/conf.d/nvim.conf
  4. create auth for nvim
    printf "<username>:$(openssl passwd -6 <password>)" > ~/lighttpd/passwd/.nvim
  5. restart lighttpd
    systemctl --user restart lighttpd
  6. start nvim
    podman-compose -f ~/podman/nvim/compose.yml systemd -a register
systemctl --user enable --now podman-compose@nvim

compose.yml

  nvim:

nvim.conf

$HTTP["host"] == "nvim.example.com" {
    auth.backend = "htpasswd"
    auth.backend.htpasswd.userfile= env.HOME + "/lighttpd/passwd/.nvim"
    auth.require = ( "" =>
    (
    "method"  => "basic",
    "realm"   => "Restricted!",
    "require" => "valid-user"
    ),
)
    proxy.server = ( "" => ( ( "host" => "127.0.0.1", "port" => "1343" ) ) )
    proxy.header = ( "upgrade" => "enable" )
