We'll use port 80 in our examples, although the process is the same for any port. As you can see I have dhcpv6-client and ssh services allowed from outside. In a previous scan we’ve determine that port 80 is open. sudo ufw allow 80/tcp means allow TCP connections to port 80.
DOCKER FOR MAC SOCAT HOW TO
You see, how the SERVER container's port 80 is mapped to the port 80 of the host system? This guide shows how to perform a Headless Installation of Alpine Linux 3. First make sure that the IP forwarding is enabled on Linux following the “Enable Linux IP forwarding” Section in Setting Up Gateway Using iptables and route on Linux. If your gateway is a physical server, you can direct traffic using firewall-cmd. SYS entirely, but that might break things using ports other than 80, so it may cause problems. yml version: '3' services: web: image: nginx:alpine ports: - 127. This way, the container is able to communicate with external systems, the real world, the internet. alpine: Pulling from library/nginx 128191993b8a: Pull complete 655cae3ea06e: Pull complete dbc72c3fd216: Pull complete.
To open a port 80 on RHEL 7 Linux we need to add an iptables rule. This same technique should work nicely with any other GUI application under Linux - I will mostly use if for running tests of QGIS based plugins and for using QGIS in my docker orchestrated environments.Alpine linux open port 80 However, there is nothing actually listening in behind the port. Here is a nice picture of QGIS (from a Linux container) running on my OSX desktop: You need to determine the IP address of your OSX machine and use it instead of the IP address listed after DISPLAY in the above command. You can mix in any standard docker options there - in this case I created shared volume between my OSX home directory and a /home/timlinux directory in the container. Lastly I ran the QGIS docker container like this: docker run -rm -e DISPLAY=192.168.0.3:0 \ -i -t -v /Users/timlinux:/home/timlinux \ kartoza/qgis-desktop qgis Next I started kinematic, and pressed SHIFT-COMMAND-T to open a docker terminal. In X11 preferences in XQuartz, in the security tab, check both boxes: Next I started XQuartz (you can close the XTerm window that opens by default). It will run in the foreground waiting for connections and then pass them over to XQuartz. I started socat like this: socat TCP-LISTEN:6000,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\"
DOCKER FOR MAC SOCAT INSTALL
Next we are going to install XQuartz - which basically gives you an X11 display client on your OSX desktop. Now install socat - a command line tool that lets you redirect sockets in unix like OS's - thankfully it runs in OSX too as it is a really neat tool! brew install socat Ok first install brew (an apt-like package manager for OSX). Run it forwarding the display to your OSX host.Grab a docker image that has a gui app you want to run (I used my the QGIS Desktop image published by Kartoza on the docker hub).I turns out that it is fairly easy to do this - here is what I did: Overview One thing I was curious about was whether it would be possible to run native GUI (X11) applications from inside docker and have them show up on my OSX desktop. Well that is what happened to me, so I decided to give working with OSX a try on this laptop with the help of docker for running all those essential apps that I use for development. Ok so here is the scenario: You just got a nice new MacBook 15" Retina computer thinking it would work as nicely for Linux as your 13" MacBook did and then you discover that the hybrid Intel/Nvidia card support in Linux is a show stopper and the WebCam does not work under Linux.
