Here are a few steps to run Tor Browser in NixOS Container w/ Pulse, Media Support. Most of the time, <code>ssh -X</code> would have sufficed. Nevertheless, to route audio the followings are needed. Prob. there is an easier way which I am not aware of.
    users.extraUsers.browser = {
      isNormalUser = true;
      home = "/home/browser";
      openssh.authorizedKeys.keys = [ SSH-KEYS-GO-HERE ];
      extraGroups = ["audio" "video"];
    };
  };
};


Need a few programs beforehand. Install the followings in your user profile.
# Open necessary ports
networking.firewall.allowedTCPPorts = [ 4713 6000 ];
hardware.pulseaudio = {
  enable = true;
  systemWide = true;
  support32Bit = true;
  tcp = { enable = true; anonymousClients = { allowedIpRanges = ["127.0.0.1" "192.168.7.0/24"]; }; };
};


<pre>
# Configuring NAT
nix-env -iA nixos.socat
networking.nat.enable = true;
</pre>
networking.nat.internalInterfaces = ["ve-browser"];
networking.nat.externalInterface = "YOUR-EXTERNAL-INTERFACE";


Use the following container conf in <code>configuration.nix</code> or derive your own.
# Depending on your use of global or home configuration, you will have to install "socat"
environment.systemPackages = [
  pkgs.socat
];
</syntaxhighlight>


<pre>
Mind to fill the SSH keys in. Then, follow the steps:
  containers.browser = {
    autoStart = false;
    privateNetwork = true;
    hostAddress = "192.168.7.10";
    localAddress = "192.168.7.11";
    config = {config, pkgs, ... }: {
      services.openssh = {
        enable = true;
        forwardX11 = true;
      };


      users.extraUsers.browser = {
<syntaxhighlight lang="bash">
        isNormalUser = true;
nixos-rebuild switch
        home = "/home/browser";
        openssh.authorizedKeys.keys = [ SSH-KEYS-GO-HERE ];
        extraGroups = ["audio" "video"];
      };
    };
  };
</pre>


Mind to fill the SSH keys in. Need to open up ports and pulse audio also:
nixos-container start browser # switch "start" with "root-login" for root
<pre>
</syntaxhighlight>
  networking.firewall.allowedTCPPorts = [ 4713 6000 ];
  hardware.pulseaudio = {
    enable = true;
    systemWide = true;
    support32Bit = true;
    tcp = { enable = true; anonymousClients = { allowedIpRanges = ["127.0.0.1" "192.168.7.0/24"]; }; };
  };
</pre>
 
Then, follow the steps:
 
# Do a usual <code>nixos-rebuild switch</code> and container will be created.
# Run the container <code>nixos-container start browser</code>.
# Root login <code>nixos-container root-login browser</code>
# Update <code>nix-channel --update </code>
# Switch <code> nixos-rebuild switch</code>


Now the container should be in a sane state to work on. Install the browser and apulse:

That's it.


Now you should be able to run the browser in a container and have media and audio support.

Here are a few steps to run Tor Browser in NixOS Container w/ Pulse, Media Support. Most of the time, ssh -X would have sufficed. Nevertheless, to route audio, the following is required. 

containers.browser = {
  autoStart = false;
  privateNetwork = true;
  hostAddress = "192.168.7.10";
  localAddress = "192.168.7.11";
  config = {config, pkgs, ... }: {
    services.openssh = {
      enable = true;
      forwardX11 = true;
    };

    users.extraUsers.browser = {
      isNormalUser = true;
      home = "/home/browser";
      openssh.authorizedKeys.keys = [ SSH-KEYS-GO-HERE ];
      extraGroups = ["audio" "video"];
    };
  };
};

# Open necessary ports
networking.firewall.allowedTCPPorts = [ 4713 6000 ];
hardware.pulseaudio = {
  enable = true;
  systemWide = true;
  support32Bit = true;
  tcp = { enable = true; anonymousClients = { allowedIpRanges = ["127.0.0.1" "192.168.7.0/24"]; }; };
};

# Configuring NAT
networking.nat.enable = true;
networking.nat.internalInterfaces = ["ve-browser"];
networking.nat.externalInterface = "YOUR-EXTERNAL-INTERFACE";

# Depending on your use of global or home configuration, you will have to install "socat"
environment.systemPackages = [
  pkgs.socat
];

Mind to fill the SSH keys in. Then, follow the steps: 

nixos-rebuild switch

nixos-container start browser # switch "start" with "root-login" for root

Now the container should be in a sane state to work on. Install the browser and apulse: 

[root@browser:~]$ su - browser
[browser@browser:~]$ nix repl
Welcome to Nix version 2.2. Type :? for help.

nix-repl> pkgs = import <nixpkgs> {}
nix-repl> :i pkgs.callPackage <nixpkgs/pkgs/applications/networking/browsers/tor-browser-bundle-bin> { mediaSupport = true; pulseaudioSupport = true; }
installing 'tor-browser-bundle-bin-8.0.6.drv'
nix-repl> :i pkgs.callPackage <nixpkgs/pkgs/misc/apulse> {}
installing 'apulse-0.1.11.1.drv'

The following two scripts are needed. Put them in ~/bin or any other directory included in the path. 

# run-tor-browser.sh (executed by the host)

#!/bin/sh
socat -d TCP-LISTEN:6000,fork,bind=192.168.7.10 UNIX-CONNECT:/tmp/.X11-unix/X0 &
xhost +
ssh -X browser@192.168.7.11 run-tor-browser.sh

# run-tor-browser.sh (executed in the container (guest) by the previous one executed on the host)

#!/bin/sh
PULSE_SERVER=tcp:192.168.7.10:4713 XAUTHORITY="/home/browser/.Xauthority" DBUS_SESSION_BUS_ADDRESS="" DISPLAY=192.168.7.10:0.0 apulse tor-browser $@

Now you should be able to run the browser in a container and have media and audio support. Alternatively, you could use Xpra over SSH 

xpra start ssh://browser@192.168.7.11/ --start=tor-browser
