What is Docker-OSX?
Docker-OSX is a specialized skill designed for developers who need to access macOS environments without physical Apple hardware. By leveraging KVM (Kernel-based Virtual Machine) acceleration on Linux, this skill provides a high-performance bridge for running macOS inside a Docker container. It is a cornerstone for cross-platform development within the Openclaw Skills ecosystem, enabling seamless transitions between Linux hosts and Apple-based software requirements.
This skill is particularly valuable for teams looking to integrate macOS-specific tasks into their existing Linux-based CI/CD pipelines or local development workflows. It eliminates the need for dedicated Mac hardware for basic compilation tasks, providing a portable and reproducible environment for iOS and macOS development.
Docker-OSX Use Cases
- Building and signing iOS apps or IPAs directly on Linux servers.
- Running macOS-only software or command-line utilities for testing.
- Compiling Apple-specific codebases using xcodebuild in a headless environment.
- Setting up automated macOS build agents within a containerized infrastructure using Openclaw Skills.
- Debugging macOS-specific issues without leaving your primary Linux workstation.
How Docker-OSX Works
- The skill checks the host system for KVM support to ensure hardware-accelerated virtualization is available.
- Openclaw Skills triggers the pull and execution of the Docker-OSX image, allocating the necessary CPU and RAM resources.
- A virtualized macOS instance boots within the Docker container, which typically takes 2 to 5 minutes.
- Network ports are mapped to allow SSH (port 50922) and VNC (port 5900) access to the guest system.
- Developers interact with the macOS environment via CLI for automated builds or VNC for graphical interface tasks.
- The lifecycle is managed through simple commands to start, stop, and monitor the health of the containerized OS.
Docker-OSX Setup
Ensure your system has at least 4 CPU cores, 8GB of RAM, and 100GB of free disk space. KVM must be enabled in your BIOS/UEFI.
# Check if KVM is available
ls /dev/kvm
# Install Docker if not present
curl -sSL get.docker.com | sh
# Use Openclaw Skills to manage the VM
start macos
status macos
