Installing the Kubos SDK¶
The Kubos SDK has several hardware requirements, including:
- 64-bit processor with AMD-V or Intel VT-x virtualization support
- Mac OS (10.9 +), Windows 7 SP1 (or more recent), or a mainstream Linux distribution (see the full list of supported host OSes)
- 8 GB RAM
- 10 GB of free HDD space
Install Windows PowerShell v3+ (Windows 7 SP1 Only)¶
If you are running Windows 7 SP1, you must upgrade your version of Windows PowerShell to atleast v3.0.
You can verify your current version by opening Windows Command Prompt and running the following commands:
$>powershell Windows PowerShell Copyright (C) 2016 Microsoft Corporation. All rights reserved. PS $> $PSVersionTable.PSVersion Major Minor Build Revision ----- ----- ----- -------- 2 0 -1 -1 PS $> exit
Major field should have a value of atleast
Vagrant requires a virtualization “provider”. Currently the only provider that Kubos officially supports is VirtualBox.
- Download VirtualBox
- Download the VirtualBox Extension Pack to enable passing USB devices into a virtual machine.
If you’re using Linux as your host operating system you will need to add
yourself to the
vboxusers group with the following command:
sudo usermod -aG vboxusers <username>
You will need to logout and log back in to your host computer, otherwise passing USB devices through to your development environment will not work correctly.
Create your Kubos SDK Instance:¶
To create an instance of the SDK box follow these steps:
$ vagrant init kubos/kubos-dev $ vagrant up
This will create a Vagrantfile in your current directory. Vagrantfiles are important as they contain the configuration details for specific boxes. Additionally, Vagrant environments are dependant on the directory they were created in. To interact with this box in the future you will need to navigate back to this directory.
If the output of
vagrant up mentions there’s a new version of the
kubos-dev box available you can upgrade your box with the following
THIS WILL OVERWRITE ALL FILES IN YOUR EXISTING BOX
$ vagrant box update
Mounting a Host Directory¶
In the context of these documents, as well as virtual machines in general, the physical “main” computer is referred to as the “host”. The virtual machine inside of the host is referred to as the “guest”.
It is strongly recommended that you create your project in a directory on your host that is shared with your box. By keeping your project on your host it will protect them in the event your box is destroyed or re-built.
Windows does not support Linux symlinks. If, for some reason, you need to create symlinks in your project, you will need to do so in a directory which lives entirely within the VM.
KubOS does not currently leverage any symlinks, so this should not be an issue for the average developer’s workflow.
To mount a specific directory from your host, open the Vagrantfile located in the directory from the previous step and look for the following lines:
# Share an additional folder to the guest VM. The first argument is # the path on the host to the actual folder. The second argument is # the path on the guest to mount the folder. And the optional third # argument is a set of non-required options. # config.vm.synced_folder "../data", "/vagrant_data"
The default home directory in the Kubos Vagrant boxes is
Uncomment the last line in this block and change the paths to match your host directory and a desired mount point in the box.
The path in the box must be an absolute path
After a volume is mounted into the box all of the data from the host
path will be available at the path specified for the box. In the above
example the host path (
../data) would be exposed at
/vagrant_data inside of the box. This allows you to use the text
editor of your choosing to edit the project files from your host machine
at the host directory path.
If you make changes to the Vagrantfile after the box has been
started you will need to run
vagrant reload for these changes to
take effect in the box.
For more information on mounting volumes see the following guide
Exposing Network Ports¶
If you would like to interact with Kubos services running inside an SDK instance from your host environment, you will need to update your Vagrantfile to expose either a single port, or your entire SDK as with a private network address.
We recommend that you set up a private network connection, since you may want to interact with multiple different network ports while developing with KubOS.
To do so, enable the following line in your Vagrantfile:
config.vm.network "private_network", ip: "192.168.33.10"
Start the Vagrant Box¶
To start the box, run:
$ vagrant up
After the box has started you need to “ssh” into the machine to work with your projects.
$ vagrant ssh
This will start an SSH session in the Vagrant box with the Kubos CLI and all of the required dependencies installed.
That’s it! From here see more on:
