Using Docker Machine to provision a VM running Docker on Azure
Docker Machine facilitates the creation and management of virtual hosts running Docker engine https://docs.docker.com/machine/overview/ . This could be a host running within a VM on your local machine, via technologies such as Hyper-V or in a public cloud such as Microsoft Azure. Docker Machine uses drivers to enable deployment to different platforms
During this post we will provision a VM running Docker on Microsoft Azure and deploying containers to the VM. We will use the Azure driver for Docker Machine which is documented here https://docs.docker.com/machine/drivers/azure/ .

The PowerShell in this post are all included in the file DockerMachineSteps.ps1 to reduce the need to copy/paste commands.
NOTE: The following process uses PowerShell which is currently in preview on Linux and Mac. I have tested the steps on Ubuntu 16.04 but as cross platform PowerShell support . The Azure CLI can be used as an alternative to PowerShell on none Windows platforms.
If you haven't already got PowerShell installed on your system (potentially a you are using a none Windows OS) follow the instructions applicable for your operating system: https://github.com/PowerShell/PowerShell
Azure PowerShell Module
Open a PowerShell prompt by typing
powershellat a command prompt/terminal:
Run the command:
Install-Module AzureRM -Force
NOTE: If you have problems getting the above commands to work and are using a Linux/Mac OS please check out the following article:
Docker for Windows/Mac
Includes Docker CLI Client, Docker Engine, Docker Compose and Docker Machine:
- Windows: https://docs.docker.com/machine/install-machine/
- Mac: https://docs.docker.com/docker-for-mac/
Requires individual installation of Docker components
- Docker Engine: https://docs.docker.com/engine/installation/
- Docker Machine: https://docs.docker.com/machine/install-machine/
Visual Studio Code
Retrieve your Azure Subscription ID
Log in to Azure:
Retrieve your subscription ID:
If you only have one Azure subscription:
If you have multiple Azure subscriptions
View list of subscriptions find the name of the subscription you wish to use:
with the name of the subscription:
$SubscriptionId= (Get-AzureRmSubscription-SubscriptionName '<your_subscription_name>').SubscriptionId
Create a virtual machine on Azure running Docker Engine
To configure variables required to provision the VM run the following lines with your preferred values. A list of current Microsoft Azure regions can eb found here: https://azure.microsoft.com/regions/
$DockerMachineVMName = '<vm_name>' $Region = '<azure_region>' $ResourceGroup = '<resource_group_name>'
To create the VM, run the following command. The parameters used and additional parameters are documented here: https://docs.docker.com/machine/drivers/azure/ .
docker-machine create --driver azure ` --azure-subscription-id $SubscriptionId ` --azure-location $Region ` --azure-resource-group $ResourceGroup ` --azure-image "canonical:UbuntuServer:16.04.0-LTS:latest" ` $DockerMachineVMName
Please follow any instructions output by the command that may be required to authenticate with Azure. Wait while the virtual machine is provisioned. This may take 5 minutes or more.
Connect to the VM
Run the following command to view the details required to connect Docker Machine to the VM:
docker-machine env $DockerMachineVMName
To connect Docker machine to the new VM:
docker-machine env $DockerMachineVMName | Invoke-Expression
Verify connected to Docker Engine on the VM:
Congratulations you are now connected to your new Docker VM!
