At WWDC 2025, Apple unveiled its Containerization framework and Container CLI, enabling developers to run Linux containers as lightweight virtual machines on macOS. This open-source initiative removes the need for external tools like Docker, prioritizing security, performance, and privacy. Each container operates within its sophisticated virtual machine, providing enhanced security through isolation and dedicated resources like unique IP addresses, thus optimizing network access. Additionally, resource allocation such as CPU and memory is container-specific, promoting efficiency when containers are not in use. The Swift-based framework, featuring a custom init system, reinforces Apple's commitment to native containerization solutions.
Apple's introduction of Containerization and Container CLI at WWDC 2025 revolutionizes how Linux containers can be created and managed directly on macOS.
The new open-source framework provides intrinsic Linux container support, eliminating dependencies on tools like Docker while emphasizing security, performance, and privacy.
Unlike traditional containerization methods, which depend on a shared VM, Apple's solution uses lightweight VMs for each container, thus enhancing security and resource management.
The dedicated per-container architecture grants each container its IP address and allocates CPU and memory resources efficiently, improving performance and operational effectiveness.
