A kernel is the essential foundation of a computer's operating system (OS). It's the core that provides basic services for all other parts of the OS. It's the main layer between the OS and underlying computer hardware, and it helps with tasks such as process and memory management, ...
During normal system startup, a computer's basic input/output system, orBIOS, completes a hardware bootstrap or initialization. It then runs a bootloader which loads the kernel from a storage device -- such as a hard drive -- into a protected memory space. Once the kernel is loaded into ...
Once the image is successfully pulled, select the Run button. Expand the Optional settings. In the Container name, specify welcome-to-docker. In the Host port, specify 8080. Select Run to start your container. Congratulations! You just ran your first container! 🎉 View your container You ca...
By default, a container is relatively well isolated from other containers and its host machine. You can control how isolated a container's network, storage, or other underlying subsystems are from other containers or from the host machine. ...
What are containers and how do containers enable fast-moving modern software, from the cloud to the edge? Learn how to use Ubuntu from the host kernel to container images running cloud applications to get a stable, secure, and consistent developer experi
Kernel-based virtual machines (KVM) are an open source virtualization technology that turns Linux into a hypervisor. Podman Desktop is a free, open source tool that simplifies working with containers in a local developer environment. CentOS is an open source project that releases 2 distinct Linux...
Virtualization for containers occurs one abstraction layer up from where it occurs for virtual machines, at the operating system level instead of at the kernel level (the kernel is the foundation of the operating system, and it interacts with the computer's hardware). Each virtual machine has ...

Instead, the container runtime engine is installed on the host system’s operating system, or “host OS,” becoming the conduit through which all containers on the computing system share the same OS. Containers are often called “lightweight”—they share the machine’s OS kernel and do not...
Kernels - at the heart of the operating system What is a kernel? Computer users benefit from kernels every day, but relatively few know what they really do. Without kernels, working on PCs, Macs, smartphones, or tablets wouldn’t be possible. As the interface between hardware and software,...
