Re: [docker/for-mac] Support for sharing UNIX sockets (#483)

There now exists an official workaround for this as of Docker for Mac >=

REF: File system sharing (osxfs) | Docker Documentation

The solution involves using a "magic path" specifically for SSH_AUTH_SOCK: /run/host-services/ssh-auth.sock

Mount this special path into the container via docker run args:


Note that this does not resolve the main issue of mounting arbitrary Unix sockets into a container. At least it works for ssh-agent / SSH_AUTH_SOCK!

So, this fix does not help when setting up a reverse web proxy to a Unix socket in the container (as mentioned above).

recserv - HP SharedX Receiver Service SYNOPSIS
/usr/lbin/recserv DESCRIPTION
HP SharedX Receiver Service provides a method for a receiver to allow the sharing of windows without explicitly performing any xhost com- mands. The Internet daemon (inetd(1M)) executes recserv when it receives a service request at the port listed in the services data base for recserv (see inetd(1m) and services(4)). When recserv is executed via inetd, a dialog box appears informing the receiver of the share request by the sender. The receiver can allow or disallow the share request by selecting the YES or NO button. recserv allows sharing by xhosting the sender just long enough for it to make a connection to the receiver. Once the connection is estab- lished recserv removes the sender from the access control list, unless the sender was entered in the list prior to the execution of rec- serv. Since no permanent change is made to the access control list, security is maintained at its highest level. To start recserv from the Internet daemon, the configuration file /etc/inetd.conf must include the single line entry, recserv stream tcp nowait bin /usr/lbin/recserv recserv -display :0 If the sharing is going to be done between IPv6 machines, the protocol field of the above entry in /etc/inetd.conf file of the receiver machine should be changed to tcp6 as follows recserv stream tcp6 nowait bin /usr/lbin/recserv recserv -display :0 and the services file /etc/services must include the line, recserv 7815/tcp # SharedX Receiver Service Receiver Service options, set by selecting the Options button, dictate the behavior of recserv. The behavior can also be set by running recserv manually. In either case, an X server resource is set dictating the behavior for subsequent invocations of recserv. OPTIONS
The following options allow different behavior according to user preferences. AlwaysAsk The dialog will pop up each time sharing is requested, regardless of the security on your X server. AlwaysAllow The dialog box never appears, but sharing will always be allowed. AskUnhosted The dialog will pop up only if the sender's machine is not hosted on your machine. If the sender's machine is already hosted, sharing will occur without a dialog appearing. NeverAsk The dialog will never appear. Windows are shared only if the sender's machine is already hosted by your server. To set resources (system behavior, label strings, etc) globally for a system, edit the file /usr/lib/X11/app-defaults/RecServ. AUTHOR
HP SharedX Receiver Service was developed by Hewlett Packard. SEE ALSO
