Docker Mac Brew
In this post I want to cover how you can setup a Docker development environment on Windows/Mac. As you might already know Docker requires a Linux kernel to run. Therefore we will always need a VM to run the actual Docker environment when you are on Windows or Mac OS. Hereby a few quotes from the Docker webpage to remember you what Docker is all about, or to give you a quick idea.
Docker provides a common framework for developer and IT teams to collaborate on applications. With a clear separation of concerns and robust tooling, organizations are able to innovate faster with greater control.
If you run into issues installing Docker, see the Logs and troubleshooting section of the Docker installation guide for additional troubleshooting tips. Step 4: Install Homebrew The recommended approach for installing the AWS SAM CLI on macOS is to use the Homebrew package manager. Homebrew Docker Virtualbox (But not only VirtualBox) This formula resolves the Docker issue on AMD based MacOS (Ryzentosh). Also can be used on any Mac. An alternative solition which worked for me: remove docker and docker-compose installed by brew; install Docker Desktop for Mac; run it and pass admin credentials to start everything.
AGILITY
Developers have the freedom to define environments, and the ability to create and deploy apps faster and easier. IT ops have the flexibility to quickly respond to change.
CONTROL
Developers own all the code from infrastructure to app. IT ops have the manageability to standardize, secure, and scale the operating environment.
PORTABILITY
Docker gives you choice without complexity, from a laptop to a team, to private infrastructure and public cloud providers.
Ok enough chatting, for the impatient ones continue to TL;DR. For all the others lets continue reading.

Put the whale to the water
Lets have a look how we can get an environment running on Windows or Mac. In this tutorial I’m going to use Chocolatey. Chocolatey is a package manager for Windows. It allows you to install the software you require from PowerShell. Rd client app. This makes it really powerful to script all the software you require on your computer by putting it in a PowerShell script. When unfamiliar with Chocolatey I recommend you to have a look at the Chocolatey webpage and install the tool as described on their page.
Adobe audition 1.5 free. For the readers using a Mac, I will mention when you have to slightly differ your approach. In all the other cases you can run the same commands. For Mac I will be using a similar tool as Chocolatey, called Homebrew. When unfamiliar with this tool I assume you know how to install the packages manually or just have a look at Homebrew to figure out how to set it up on your Mac.
From this point I assume you have Chocolatey/Homebrew installed. In case you don’t I’ll also assume that you know how to install the required tools manually by downloading the correct installers. In order to get a VM running for our Docker environment we are going to use docker-machine to setup a docker-machine on VirtualBox. So lets start by installing Virtualbox, docker-machine and Docker using Chocolatey. In case you have any of these tools already installed you can skip this step.
Install tools
docker-machine
Now we have installed docker-machine we are able to create a new environment. In case you already had docker-machine installed we can first have a look on what machines we have available using the following command.
In my case I already have the machine created. In case you also have a machine there already you might want to just use that one. For the ones started from scratch I will show you now how to create a machine.
Note: In case you just created your machine from scratch, we first have to boot it. You can do so by running following command. In case your machine is already running you can skip this step.
With the command shown previously we created a machine named default using the virtualbox driver. So when you run the docker-machine ls command now, you should have similar output as you have seen before. You will also be able to see if the machine is running. We also see in the last line of the creation output that there is a special command which will provide you the information in order to connect your Docker client to this specific machine (docker-machine env default). Lets configure the PowerShell environment to connect Docker to this specific machine.
Remember when you are running this command from Mac it will output it differently. The same goes when you are using Bash/Cygwin on Windows or when you are using the regular Command-Prompt on Windows. So just run the command in your preferred console and execute the command as shown in the output. In our case I’m going to continue using PowerShell, which means I will execute the command as we have just seen.
docker
Lets configure our PowerShell.
For Mac users the command will be something like following on bash.
Now we will be able to use Docker on Windows. Lets try using the docker/whalesay image to test our Docker environment.
In this article I won’t go much deeper in the usage of Docker itself. So things like creating your own images, multi-container solutions and other more in depth Docker stuff won’t be covered as it is out of scope. Therefore I only want to point you to docker --help on your console and the Docker documentation for now, so I won’t leave you completely in the dark. I might be publishing another post on how to run your project in Docker later.
Play time
The docker/whalesay image also has command line help which reveals some more options (docker run docker/whalesay cowsay -h). It reveals for example the whale can also think instead of talk (docker run docker/whalesay cowthink 'Will he see the difference?'). Have fun playing around with the docker/whalesay image and the other options revealed in the help or simply try out some other images from the Docker hub.
Wrapup
If you finished playing around with Docker you might want to shutdown the VM using docker-machine stop default. Next time you want to use it again simply run docker-machine start default and docker-machine env default to start and configure your environment. Last but not least I would like to point you to the --help option. It will provide you with usage information on the command line options for every single command.
TL;DR
As a bonus I want to give you all the commands we require to setup our environment in a PowerShell script. So feel free to save the contents in a ps1 file which you can call from your PowerShell.
Windows
Mac
Finally, when you are finished playing arround with Docker, you might want to shut down your vm. You can do so by running.
In case you where one of the impatient ones, now realizing you have no clue what just happened when you called the commands in above example. Here you go for a second shot.

Again thanks for reading this article, and as always share your feedback and questions in the comments.
Just recently I had to install Docker on my MacOS machine. Here I want to give you a brief walkthrough on how to achieve it. First of all, we need Homebrew to install all the necessary Docker dependencies. If there isn't a Homebrew installation on your Mac, follow this guide for a developer setup.
Install the docker dependency with Homebrew after making sure that all Homebrew dependencies are on the latest version:
You will also need a MacOS specific environment in which Docker can be used, because natively Docker uses a Linux environment. Therefore, install the docker-machine and virtualbox dependencies:
Note: If the last install fails, check your MacOS' System Preference and verify if System software from developer 'Oracle America, inc' was blocked from loading. shows up. If you see it, hit the 'Allow'-button and install it again.
Optional: if you want to use Docker Compose later, install the docker-compose dependency with Homebrew:
Everything related to Docker and its environment is installed now. Let's get started with using it. First, create an engine for Docker on MacOS. This needs to be done only once, unless you want to create more than one engine by giving them other names than default. Usually one engine should be sufficient.
Using the following command for your Docker Machine, you should see whether your last Docker engine got created and whether you have more than one engine if desired:
Usually the Docker engine's STATE should be Running. If it isn't, like it's shown in the last output, you can start the engine with Docker Machine:
Checking your list of Docker engines again should lead you to one running Docker engine:
Just for the sake of knowing about it, you can stop your Docker engine anytime too:

Make sure that your Docker engine is running for the next steps. Last, we need to configure the environment variables for Docker. Run the following command to find out how:
Macbook os x yosemite download free. Usually this prints out the command to set all the env variables set for MacOS; which is the following:
Finally, you should be able to start a Docker container with a pre-defined Docker image to check whether everything works as expected:
The first time running this command should take some time, because the pre-defined Docker image is pulled from a remote server. Every additional time you run this command, it should print its output almost in an instant, because the Docker image is already there and the build for the Docker container from the Docker image doesn't take long for this example. Congratulations, Docker is running on your Mac machine now.
