Docker does not provide a native feature that does that out-of-the box, as far as I know, but: You can build an image which:. expects an environment variable Machost (meaning you have to launch it with docker run -e MACHost 08002Bdeadb, as suggested in '). will, as part of its background process, test that environment variable value, and exit immediately if it does not match a certain value (or if the environment variable is not set at all) As by, a MAC address can easily be spoofed. But that same procedure can be applied to a different data: a digital signature that your image would be able to verify through an embedded public key. The user would have to pass a message, the same encrypted message, and information about how to verify the signature. He/she would only be able to do that from the machine with the right private key. And the image can then, when starting its main process, perform performs the decrypt operation and compares his output with the original data.
If that does not match. It would exit immediately. The idea is: a private key is. Private: only one machine should have it.
A Docker image is a file encapsulating an application and all its dependencies in a single complete environment. An image is loaded into a container These containers can run on any host machine with Docker installed. So, whether you’re on Windows, Mac, or Linux, and regardless of what. This image runs fine on docker in linux (tested with ver 1.11.2), but fails to run on Docker for Mac beta (1.12.0-rc4-beta20, diagn General description I have created an Image based on the official postgres:9.5.3 image.
And that would ensure the image can only be run on that unique machine.
First Touch Down with Docker for Mac Sun, Mar 27, 2016 A few days ago, Docker has announced a closed BETA program for their new applications “Docker for Mac” and “Docker for Windows”. These apps are meant to simplify the usage of Docker containers for every developer even more. They try to lower the barrier to install and use Docker on your desktop and laptop computers for both Mac and Windows users. As soon as I received the first rumors that there is a special feature built-in, which should also simplify the developers workflow for IoT applications, I was getting totally thrilled and registered immediately for the BETA program. It was really hard to wait for, but luckily I’ve received an email with my BETA invitation and access token within a few hours only. Here I’d like to give you a first insight view how to install and use “Docker for Mac” with a basic walk-through on my MacBook Pro running the very latest OS X 10.11.4.
So, please join me on this journey Access to the BETA program You can easily register to the Docker BETA program at. Once you’re logged in with your Docker ID (which is literally your Docker Hub user account) you can apply for testing “Docker for Mac” and “Docker for Windows”. As this is a closed BETA, you’ll get on a waiting list and hopefully will be selected soon. So, please be patient until you’ll receive an invitation email with some more detailed instructions and a personal access key. For this blog post, I’ll show you how easy it is to install and use Docker on OS X.

And I guess, we’ll write another post later for all the curious Windows users, too. Download and install “Docker for Mac” When you’re selected for the BETA, you’ll receive an email titled “Docker Private Beta” with a link to the download page and an access key. Download the installer package called “Docker.dmg” to your Mac and double click it, drag and drop the “Docker beta” app to your Applications folder. Now, from your Lauchpad you can start the “Docker beta” app directly the first time and you can begin right away using Docker on your Mac. Once you start the BETA Docker app the first time you’ll be asked to enter your personal invite token. Token has been accepted.
The Docker app needs to additionally install a network helper and requests for privileges to do so. Enter your credentials to grant privileged access. Success, the Docker app is installed and you can easily find and access it by clicking on the little neat whale icon. Using “Docker for Mac” the first time To use Docker we’ll just start a terminal window and use the Docker CLI to access the local Docker Engine. First, get the version of the Docker command: Determine the versions of the Docker Client and the Docker Engine: Display some more detailed informations about the installed Docker software: Let’s start a real Docker container First, we’ll check how our host operating system looks like: uname -a Darwin demo.local 15.4.0 Darwin Kernel Version 15.4.0: Fri Feb 26 22:08:05 PST 2016; root:xnu-3248.40.1843/RELEASEX8664 x8664 As already expected we see our host OS is OS X or Darwin with a kernel version 15.4.0. Our CPU architecture is x8664, which indicates that we’re running on an Intel-based 64-bit CPU. Second, let’s start a basic Linux container and here we’re using a Debian standard distro for now. This will take a few second because the Docker Engine has to fetch/download the Docker image debian from the Docker Hub.
