Can you list the existing namespace areas in Docker?

In Docker, there are several naming (namespace) areas that isolate various container resources from each other and from the host. The main namespaces are:

• PID namespace — isolates process identifiers so that processes inside the container do not see processes outside the container.
• Network namespace — isolates network interfaces, IP addresses, and ports.
• Mount namespace — isolates filesystem mount points.
• UTS namespace — isolates hostname and domain name.
• IPC namespace — isolates inter-process communication (shared memory segments, message queues).
• User namespace — isolates user and group IDs, allowing the container to have its own UID/GID different from the host.

These namespaces provide isolation and security for containers, enabling them to operate as separate systems within a single host.
