As I want to decouple my development server from my computer as much as possible I want to create first a virtual machine with linux.
Because I have used Oracle Virtualbox in the past successfully, I will use it here too.
As I don’t want create a new linux from scratch, I have looked for a ready system at Vagrantboxes, which contains a new Oracle Linux version, and find a Oracle Linux 7.1 x86_64 system with Chef and Puppet preinstalled.
For automatic update of the Oracle VM VirtualBox Extension Pack, which is delivered with the ready box and is required for use of shared folders and more, you should install following plugin as described here:
vagrant plugin install vagrant vbguest
Next I have created a directory of your choice and init there a Vagrantfile by calling
Then I changed the Vagrantfile as following, see the inline comments for documentation:
Vagrant.configure(2) do |config| # Use the mentioned ready OEL 7 linux box config.vm.box = "oraclelinux-7-x86_64.box" config.vm.box_url = "http://cloud.terry.im/vagrant/oraclelinux-7-x86_64.box" # Create a private network config.vm.network "private_network", type: "dhcp" # persistant storage for all docker container config.vm.synced_folder "C:\\shared\\virtual_storage", "/virtual_storage", :mount_options => ["dmode=777","fmode=777"] # virtualbox provider config.vm.provider "virtualbox" do |vb| # name in VirtualBox vb.name = "Development Server" end # Docker Private Registry container for storing later builded docker images, which are not in the Docker Public Registry at https://hub.docker.com/ config.vm.provision "docker" do |d| d.run "registry", image: "registry", daemonize: true, args: "-d -p 5000:5000 -v /virtual_storage/docker_registry:/var/lib/registry" end end
Run next from the created directory
Following you see the output

|1||you see the loading of the ready box and booting with the defined network|
|2||the version of the VirtualBox GuestAdditions of the box is checked and after that replaced with the actual installed VirtualBox version. This happens only on the first "vagrant up" call.|
|3||Docker is installed as a Vagrant Docker provider is called in the Vagrantfile line 20 and it does not exist in the box before.|
|4||a Docker Private Registry container is started via loading docker image from the Docker Public Registry. In a later blog we will use this Docker Private Registry container to hold our own created docker images like database and development tools. The pushed images are saved to a mapped host volume of my windows 10 computer.|
You can connect to the virtualbox directly via
The you can see the downloaded Docker Private Registry images and the started container from this images:

You can now stop the Development Server via
If you startup again the server via
the provision steps are not replayed until you destroy the server or explicitly call the provision again via
