Milliseid meetodeid ja tehnoloogiaid kasutab operatsioonisüsteem konteineriseeritud rakenduste haldamiseks?

The operating system manages containerized applications using several key technologies and mechanisms:

• Namespaces — isolate processes, network, file system, and other resources so that containers do not overlap and do not influence each other.
• Control Groups (cgroups) — limit and control resource usage (CPU, memory, disk, network) for each container, preventing limit breaches.
• Union file systems (OverlayFS, AUFS, etc.) — enable the creation of layered file systems, where the container's base image is immutable, and changes are recorded in the upper layer.
• Network drivers and virtual interfaces — create isolated network spaces for containers with the ability to configure bridges, NAT, and other network policies.

These mechanisms together ensure container isolation, resource management, and security at the kernel level, enabling efficient deployment and control of containerized applications.
