Orka Desktop 3.0 User Guide

Orka Desktop is a free, no obligation, virtualization tool, which is designed to be deployed on individual macOS workstations. These workstations might be a local Macbook, a hosted Mac mini or Studio by MacStadium, AWS, or even an individual On-Prem solution. Once deployed, Orka Desktop allows users to create a seamless workflow for running the same image on any device. An image can be built and tested locally, then uploaded to the cloud. This is much easier than needing bespoke technologies, and individual processes to test, share, and configure virtualized images.

Orka Desktop integrates with other cloud based, licensed MacStadium products, like Orka. For example, an image built and tested with Orka Desktop can be uploaded to a Container Repository that is shared with an Orka cloud instance, using this integrated tool. The ability to publish local images to the Orka cloud means users can develop locally and deploy globally - offering flexibility, scalability, and an on-ramp to use MacStadium products more effectively.

🗒️

NOTE

Users can publish any image to a container registry, for example, GitHub Packages or DockerHub and then pull it into the Orka Cluster.

OCI Image Overview

The Open Container Initiative (OCI) is an open governance structure for the express purpose of creating open industry standards around container formats and runtimes.

Users can deploy a VM using a compatible image from a private or public registry, as well as store those images in a user registry.

Installation and Set Up in 3 Easy Steps

Orka Desktop has a clear and intuitive GUI, which makes it easy transition to using Orka in the cloud. It provides information about your system, available images, and VMs.

1. Download Orka Desktop. Move to your Applications folder. Run Orka Desktop.
2. Create a New Virtual Machine (VM). There are two options for creating a new VM:

• Clean Install, where the image is created from an existing IPSW file.
• Pull Image, where the image is pulled from an Image Repository (based on an existing OCI image that is available via a Container Registry).

3. Use the VM.

🗒️

NOTES

• IPSW (Apple Software/Firmware) is a file format used in macOS firmware for devices equipped with Apple silicon.
• There is also the option to pull the latest IPSW directly from Apple’s servers, which is detailed in the Other IPSW Options section.

Downloading Orka Desktop

• MacStadium website: https://www.macstadium.com/
• MacStadium GitHib repo: https://github.com/macstadium/orka-desktop/releases
• Brew package manager: brew install orka-desktop

Creating a New Virtual Machine (Clean Install via IPSW Files)

1. Download Orka Desktop.
2. Open the Orka Desktop tool and the System Information screen displays.

3. Click + Create New VM

4. When the new Virtual Machine dialog box opens, select Clean Install(based on an IPSW); then use the Name field to name the VM.

🗒️

NOTES

• In this example, the new VM is called New Name Here, and at the same time, that name appears on the left-hand side of the screen, under the list of available Virtual Machines.
• The VM is now in a pending installation state.

5a. If a user wants to select an existing IPSW file, then select Other from the dropdown menu.

🗒️

NOTE

Selecting the Other dropdown opens a folder, which the user can pick the existing IPSW file to install.

5b. If a user does not have a local IPSW file to use for the new VM, then select Download Latest, to get the latest files from Apple.

🗒️

NOTE

Selecting the Download Latest dropdown opens a confirmation box.

6. Use the stepped sliders to manually adjust the number of CPUs, and the amount of Memory and Storage that you want to allocate to the VM.

8. Use the Display Resolution drop own to set the resolution of the screen when running Console into the image.
9. Use the Image Data Location to select the location of the saved files.

9. Click Install and the progress bar displays the install progress.

🗒️

NOTE

When the install completes, there is a new VM available on the Orka Desktop, which can be used to Start, Pause, Resume, Stop, or Console into.

Creating a New Virtual Machine (Pull from OCI Image)

1. Download Orka Desktop.
2. Open the Orka Desktop tool and the System Information screen displays.

3. Click + Create New VM

4. When the new Virtual Machine dialog box opens, select Pull from an Image ; then use the Name field to name the VM.

Pull from an Image

🗒️

NOTES

• In this example, the new VM is called New VM Pulled From Image, and at the same time, that name appears on the left-hand side of the screen, under the list of available Virtual Machines.
• The VM is now in a pending installation state.

5. Complete all fields with the required information.
6. Use the stepped sliders to manually adjust the number of CPUs, and the amount of Memory and Storage that you want to allocate to the VM.
7. Use the Display Resolution drop own to set the resolution of the screen when running Console into the image.

8. Click Pull.

Configuration Warnings

When adding CPU Count and Memory Size, the Orka Desktop application displays a warning message if the recommended sized are exceeded.

Starting the VM

1. Click on an existing VM on the left-hand side. In this example, the VM is Orka3.
2. Click Start.

3. A separate window opens and the VM starts.

NOTE: Starting a VM for the first time may take several minutes.

🗒️

NOTES

• This VM might be configured to run a different version of macOS from your host, so users can test the same software in two different environments. Note that you can only use OSs in VMs that are more recent than the OS running on the host.
• Users may install Xcode, then use it as a build machine for iOS apps.
• IT Admins can test Mobile Device Management (MDM) profiles using VMs, which can be easily done without maintaining several Mac mini machines. MDM profile testing can be performed on a VM that was created by Orka Desktop.
• Apple has limited the ability to sign into iCloud with an Apple ID within a VM.

Stop a VM

If a VM is running, then click the Start button to Stop it.

Console into a VM

Think of this functionality as a graphical console, which opens the VM display in a UI screen. In other words, it opens a new screen for interactions with guest OS.

Resume VM

Resumes a VM that was paused.

Push to OCI Registry

Users can push the image to an OCI registry. Push allows users to push an image, so another user can download and use that image. This is helpful for sharing an image across a team; for example, an IT Admin can create and configure an image and push it to a shared location, then team members can access that image and begin using it. Developers may also push an image to a shared registry for testing purposes.

1. Select an existing VM.
2. Click Push to OCI Registry.

3. Complete the required fields and click Push.

Push

4. A progress bar appears while the image is being pushed.

Managing the VM

Right click on an existing VM to display a dropdown menu.

• Duplicate = Duplicate can be used for upgrade testing. Use Duplicate to create a copy of the existing VM, then test the upgrade to a new VM.
• Push to OCI Registry = Users can push to an OCI registry.
• Delete = Delete is used to delete the VM from Orka Desktop.

Log Files

The following information is found in the log file: directory, image directory, and default VM settings.

The log file has four sections, with the following information:

• Node Info (Contains system details, for example, chip, cores, memory, OS version, and so on).
• Image Info (Lists images, creates new image, deploys new VM based on an image).
• VM Details (For each running VM, there are actions like, Open Screenshare, Open SSH, Stop, Save, Save As, View Log actions).
• Logs (Running logs, and any other useful information for debugging.)
