Software: The Docker daemon, called dockerd, is a persistent process that manages Docker containers and handles container objects. The daemon listens for requests sent via the Docker Engine API. The daemon listens for requests sent via the Docker Engine API.
The term was coined by the programmers at MIT's Project MAC.According to Fernando J. Corbató, who worked on Project MAC around 1963, his team was the first to use the term daemon, inspired by Maxwell's demon, an imaginary agent in physics and thermodynamics that helped to sort molecules, stating, "We fancifully began to use the word daemon to describe background processes that worked ...
The clients can issue commands to the control daemon, which would accept and divide the workload to the computing daemons. For clients, the main commands are srun (queue up an interactive job), sbatch (queue up a job), squeue (print the job queue) and scancel (remove a job from the queue). Jobs can be run in batch mode or interactive mode. For ...
systemd is the first daemon to start during booting and the last daemon to terminate during shutdown. The systemd daemon serves as the root of the user space's process tree; the first process (PID 1) has a special role on Unix systems, as it replaces the parent of a process when the original parent terminates. Therefore, the first process is ...
This behavior is enforced in some variations of cron, such as that provided in Debian, [8] so that simply restarting the daemon does not re-run @reboot jobs. @reboot can be useful if there is a need to start up a server or daemon under a particular user, and the user does not have access to configure init to start the program.
These include agents installed on the target system, "special agents" running on the monitoring server and communicating with the API of the target system, the SNMP API for monitoring, for example, network devices and printers, and HTTP/TCP protocols to communicate with web and internet services. By default, Checkmk follows the "pull principle ...
Container Linux provides no package manager as a way for distributing payload applications, requiring instead all applications to run inside their containers. Serving as a single control host, a Container Linux instance uses the underlying operating-system-level virtualization features of the Linux kernel to create and configure multiple containers that perform as isolated Linux systems.
It supports saving the virtual machine state while all programs are running. Guest operating systems do not need patching to run inside QEMU. The virtual machine can interface with many types of physical host hardware, including the user's hard disks, CD-ROM drives, network cards, audio interfaces, and USB devices. USB devices can be emulated ...
