If you use Linux as your host operating system then with one or two commands you can have most graphical Linux applications up and running on your desktop in seconds. Package managers like apt-get, yum and pacman make installing new software almost seamless. If you are running an XWindows server (which you probably are) then getting a graphical application to appear on your screen from a remote Linux system or a Docker container can be as simple as setting the DISPLAY environmental variable. But macOS though? Many applications that exist for Linux also exist for Mac: Chrome, FireFox, VLC Player, Slack, Arduino IDE etc. In some cases they have been ported and re-built natively and even optimized to take advantage of the OS. So why would you want to run Linux versions of apps on your Mac? Here are a few reasons why you may want to use Docker to run Linux applications on macOS: • To access to newer versions of software • To test various versions of the same software simultaneously • To use tools which may not be ported to macOS yet • For sandboxing an application: • To tighten up on security • or to isolate and/or spy on network traffic Since Docker provides a sandboxed environment for applications that means you can add/remove just the capabilities you want and tighten up on security. Several paid tools exist for macOS to isolate network traffic and push it down different HTTP proxies or SOCKS tunnels depending on custom rulesets. This is ideal if you frequently work on public WiFi networks or behind a restrictive corporate network. By using your own hosted proxy server or VPN you can protect some or all of your traffic. So why pay for something you can do for free with Docker? Slack for Linux running on the Mac Desktop in El Captain Step-by-step Here's what you need to do to bring X11 to your Desktop. Install an X11 server An X11 server exists for MacOS which allows applications like XTerm to run and display output on your local computer. It's packaged up as the and can be installed with: $ brew install Caskroom/cask/xquartz ==> brew cask install Caskroom/cask/xquartz ==> Creating Caskroom at /usr/local/Caskroom ==> Downloading ################################## 100.0% 2. Build your Dockerfile Once you have XQuartz set up you can then install your favourite graphical Linux apps into a Debian container or whichever distribution you prefer. Hi All, I have Openshift running in my system.I have got a Jenkins image running on it.I have successfully ran the jenkins Classic GUI.However when I am trying to run the docker commands in Execute Shell for example docker info.It is giving me an error as docker command not found. I know the issue I have installed the docker plugin from Manage Jenkins.However I am not knowing how to configure it in Manage Jenkins -> Configure System.My main intention is to build docker image out of it which helps for our CI/CD pipeline execution. Any Help from the community team is highly appreciated. We need to give the jenkins user sudo privileges in order to be able to run Docker commands inside the container. Acrobat reader plugin internet explorer. Alternatively we could have added the jenkins user to the Docker group, which avoids the need to prefix all Docker commands with ‘sudo’, but is non-portable due to the changing gid of the group (as discussed in Pini’s article). Nov 21, 2017 - add --group-add docker to the docker run command to make sure the user running inside the jenkins docker container will belong to the equivalent docker group on your host. The mounted socket: /var/run/docker.sock is resulting in confusion about which group it belongs to on the host and inside the jenkins container.
