As containers share the same kernel with the host, isolating and controlling the containers from the rest of the system becomes very important. Linux kernel does not have any specific code for the containers, these containers are implemented by multiple independent Linux kernel features like Namespaces, Cgroups, combined with filesystem tricks and enhanced with security …
What is a File Descriptor? A file descriptor is a unique identifier assigned by the operating system to each open file, socket, pipe, or other I/O resource within a process. It is represented as a non-negative integer and serves as a reference to the underlying file or resource. File descriptors are managed by the kernel …
