Rootless podman-compose configuration

Help

My updated podman.nix is below.

{config, pkgs, lib, ...}:
{
  # Enable container support
  virtualisation = {
    podman = {
      enable = true; # Needed to populate /run/user/1000/podman/podman.sock
    };
  };

  # Set graphDriverName to btrfs
  virtualisation.containers.storage.settings = {
    storage = {
      driver = "btrfs";
      graphroot = "/var/lib/containers/storage";
      runroot = "/run/containers/storage";
    };
  };
  # add podman and podman-compose
  environment.systemPackages = with pkgs; [ podman-compose slirp4netns fuse-overlayfs ];

  # Allow non-root containers to access lower port numbers
  boot.kernel.sysctl."net.ipv4.ip_unprivileged_port_start" = 80;

  # Enable lingering so containers persist after ssh exit
  users.users.<user-name>.linger = true;

  # Automatically start containers on boot
  systemd.services.podman-autostart = {
    enable = true;
    after = [ "podman.service" ];
    wantedBy = [ "multi-user.target" ];
    description = "Automatically start containers with --restart=always tag";
    serviceConfig = {
      Type = "idle";
      User = "<user-name>";
      ExecStartPre = ''${pkgs.coreutils}/bin/sleep 1'';
      ExecStart = ''/run/current-system/sw/bin/podman start --all --filter restart-policy=always'';
    };
  };
}
