In Kubernetes version 1.9, the initial Alpha release of Container Storage Interface (CSI) was introduced. [70] Previously, storage volume plug-ins were included in the Kubernetes distribution. By creating a standardized CSI, the code required to interface with external storage systems was separated from the core Kubernetes code base.
Container clusters need to be managed. This includes functionality to create a cluster, to upgrade the software or repair it, balance the load between existing instances, scale by starting or stopping instances to adapt to the number of users, to log activities and monitor produced logs or the application itself by querying sensors.
OpenShift is a family of containerization software products developed by Red Hat.Its flagship product is the OpenShift Container Platform — a hybrid cloud platform as a service built around Linux containers orchestrated and managed by Kubernetes on a foundation of Red Hat Enterprise Linux.
Helm is a package manager for Kubernetes. [ 1 ] [ 2 ] It uses 'charts' as its package format , which is based on YAML . Helm was accepted to Cloud Native Computing Foundation on June 1, 2018 at the Incubating maturity level and then moved to the Graduated maturity level on May 1, 2020.
Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels. [8] Because all of the containers share the services of a single operating system kernel , they use fewer resources than virtual machines .
Company CEO Sheng Liang says that as organizations increasingly operationalize Kubernetes there is now a lot more focus on lifecycle management and scalability. Version 2.4 of Rancher provides access to a set of tools that makes it easier for IT teams to manage a fleet of Kubernetes clusters even when network connectivity is limited, says Liang.
OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, including containers (LXC, Solaris Containers, AIX WPARs, HP-UX SRP Containers, Docker, Podman), zones (Solaris Containers), virtual private servers (), partitions, virtual environments (VEs), virtual kernels (DragonFly BSD), and jails ...
The Cloud Native Computing Foundation (CNCF) is a Linux Foundation project that was started in 2015 to help advance container technology [1] and align the tech industry around its evolution. It was announced alongside Kubernetes 1.0, an open source container cluster manager, which was contributed to the Linux Foundation by Google as a
