The app and command line interface are designed to be simple yet powerful, enabling you to set up Linux machines in just one minute. ### **Robust Connectivity** OrbStack offers robust connectivity features, including support for IPv6 and ICMP. It ensures painless integration with VPNs and DNS, making it easier to connect between Linux machines and Docker containers. Developers can run x86 containers with Rosetta and enjoy fast, reliable networking and file sharing. ### **Optimized for Apple Silicon** OrbStack is optimized for Apple Silicon, providing unmatched performance and efficiency. It uses less than 10 MB of disk space out of the box and ensures that your machine remains responsive and efficient. Developers can run Intel machines on Apple Silicon with Rosetta, making it a versatile solution for various development needs. ### **Packed with Features** OrbStack is packed with features that simplify your workflow and help you move faster. Some of the key features include: * 2-second startup * 45 Gbps network * Seamless macOS integration * Docker and Linux machines support * Rosetta x86 emulation * Dynamic disk usage * Native Swift app * SSH agent forwarding * File sharing * 2-way CLI integration * Support for 15 Linux distros * VPN-friendly * Low initial memory usage * Accurate clock * Works without admin privileges * Bind mounts and Docker volumes on Mac * Host networking and eBPF support * Native Docker UI ![](https://cdn.hashnode.com/res/hashnode/image/upload/v1727013075749/bdc78a35-bde0-4c6d-ba2f-472483f71a35.png align="center") ![](https://cdn.hashnode.com/res/hashnode/image/upload/v1727013161726/e4d5ad6f-4a0d-424c-9647-9488c038543c.png align="center") ### **Easy Transition from Docker Desktop and Colima** Switching from Docker Desktop or Colima to OrbStack is seamless. OrbStack automatically migrates your Docker Desktop data, including containers, volumes, and images. You can also run OrbStack and Docker Desktop or Colima side-by-side using Docker contexts. Reverting back is just as easy, ensuring a smooth transition. ### **Docker** while immensely popular and powerful, can be resource-intensive, especially on macOS. Here are some of the key points regarding the "heaviness" of Docker: * **CPU and Memory Consumption**: Docker Desktop can consume significant CPU and memory resources, even when idle. This can lead to slower performance of other applications and overall system sluggishness. * **Disk Space**: Docker images and containers can take up a considerable amount of disk space. Over time, as more images and containers are created, the disk usage can grow substantially, requiring regular cleanup. * **Battery Drain:** On laptops, especially MacBooks, Docker Desktop can lead to noticeable battery drain. The constant background processes and resource usage can reduce battery life significantly. * **Complex Virtualization:** Docker on macOS relies on a virtual machine (VM) to run Linux containers. This adds an additional layer of complexity and resource usage. The VM itself requires resources, and the overhead of running containers within the VM can further impact performance. * **Network Overhead:** Networking in Docker can introduce additional overhead. The virtual network interfaces and the need to bridge between the host and container networks can lead to increased latency and reduced network performance. * **Startup Time:** Starting Docker Desktop can be slow, as it needs to initialize the VM and the Docker engine. This startup time can be a hindrance, especially when quick access to containers is needed. * **Maintenance:** Managing Docker involves regular maintenance tasks such as cleaning up unused images, containers, and volumes. Failure to perform these tasks can lead to bloated disk usage and degraded performance over time. * **Compatibility Issues:** Docker's reliance on virtualization can sometimes lead to compatibility issues with other software, particularly those that also use virtualization or require low-level system access. ### Installation and Usage of OrbStack #### Installation 1. **Download and Open**: Simply download OrbStack from the official website and open it. No installation is needed. 2. **Homebrew**: Alternatively, you can install OrbStack using Homebrew: ```bash brew install orbstack ``` #### Getting Started OrbStack is ready to use out of the box. Here are some initial steps to get you started: 1. **Run a Docker Container**: ```bash docker run -p 80:80 docker/getting-started ``` 2. **Create and Start a Linux Machine**: * Choose your favorite Linux distro in the app to create a new machine. * Double-click to start it or use the `orb` command. #### Tips for Optimal Usage * **Docker**: * Compose and other tools are included. * Use volumes at `~/OrbStack/docker` for optimal file system performance. * **CPU Usage**: * Minimize by stopping containers when not in use. * **Memory Usage**: * Decrease memory limit in Preferences for lower usage. * **Network**: * Host networking, VPNs, DNS, IPv6, ping, traceroute, etc., just work. #### For Linux Machines * **CLI and GUI**: * Use the `orb` command for the command line interface or the native Swift app for GUI. * **File Sharing**: * Access macOS files in Linux at the same paths or with `/mnt/mac` prefix. * Access Linux files from macOS at `~/OrbStack` or in the app. * **SSH**: * Use `ssh orb` to connect to Linux machines. * For Visual Studio Code, install the "Remote - SSH" extension. * **Integration**: * Run macOS commands and send notifications from Linux using the `mac` command. * Link commands with `mac link`. * SSH agent is forwarded automatically. #### Switching from Docker Desktop or Colima * **Seamless Transition**: * Open OrbStack and get started. It will offer to migrate your Docker Desktop data automatically, including containers, volumes, images, and more. * **Side-by-Side Usage**: * Use Docker contexts to run OrbStack and Docker Desktop or Colima side-by-side ### Reference Documents > 1.
