What is photon Linux?
Photon OS is a Linux container host optimized for vSphere and cloud-computing platforms such as Amazon Elastic Compute and Google Compute Engine. As a lightweight and extensible operating system, Photon OS works with the most common container formats, including Docker, Rocket, and Garden.
What is a cri-O?
What is CRI-O? CRI-O is an implementation of the Kubernetes CRI (Container Runtime Interface) to enable using OCI (Open Container Initiative) compatible runtimes. It is a lightweight alternative to using Docker as the runtime for kubernetes.
What is Crictl?
crictl is a command-line interface for CRI-compatible container runtimes. You can use it to inspect and debug container runtimes and applications on a Kubernetes node. crictl and its source are hosted in the cri-tools repository.
Is containerd part of Docker?
containerd is a container runtime with an emphasis on simplicity, robustness, and portability. It was and still is included with Docker. It’s the runtime Docker uses to pull images from image registries, create containers, manage storage and networking, and interact with containers.
What is CRI O?
CRI-O is an implementation of the Kubernetes CRI (Container Runtime Interface) to enable using OCI (Open Container Initiative) compatible runtimes. It is a lightweight alternative to using Docker as the runtime for kubernetes.
How is CoreOS immutable?
Fedora CoreOS is designed to be managed as immutable infrastructure. After a machine is provisioned, you should not modify /etc or otherwise reconfigure the machine. Instead, modify the FCC and use it to provision a replacement machine.
Is Podman free?
Windows users can install Podman on WSL2, but for MacBook users (like myself) Podman is shipped together with an integrated Linux VM (Podman machine) for free.
What are the main components in Openshift architecture?
OpenShift includes everything you need for hybrid cloud, like a container runtime, networking, monitoring, container registry, authentication, and authorization.
What is Rhcos?
Red Hat Enterprise Linux CoreOS (RHCOS) represents the next generation of single-purpose container operating system technology by providing the quality standards of Red Hat Enterprise Linux (RHEL) with automated, remote upgrade features.
Is photon debian based?
Photon OS is a minimal Linux container host, optimized to run on VMware platforms (though it is capable of running in other environments).
Is ESXi Photon OS?
Photon OS can be installed on ESXi from either an ISO image or an Open Virtual Appliance (OVA). The OVA image only includes a minimal environment, while the ISO image lets you choose between a full install or the minimal environment.
What is VMware Photon OS based on?
VMware’s Photon Platform is made up of two components: Photon Machine and Photon Controller. Photon Machine essentially couples a slimmed down version of VMware’s ESX hypervisor (called a microvisor) and VMware’s Photon Linux operating system to create a lightweight container runtime.
What is Minikube in Kubernetes?
Minikube is a lightweight Kubernetes implementation that creates a VM on your local machine and deploys a simple cluster containing only one node. Minikube is available for Linux, macOS, and Windows systems.
What are Kata containers?
Kata Containers is an open source community working to build a secure container runtime with lightweight virtual machines that feel and perform like containers, but provide stronger workload isolation using hardware virtualization technology as a second layer of defense.
Is Kubelet a pod?
The kubelet works in terms of a PodSpec. A PodSpec is a YAML or JSON object that describes a pod. The kubelet takes a set of PodSpecs that are provided through various mechanisms (primarily through the apiserver) and ensures that the containers described in those PodSpecs are running and healthy.
What is Nerdctl?
nerdctl is a Docker-compatible CLI for containerd . ✅ Supports rootless mode ✅ Supports lazy-pulling (Stargz) ✅… github.com. The UI/UX of nerdctl is same as docker and podman .
What is Cgroup driver?
Cgroup drivers
Control groups are used to constrain resources that are allocated to processes. When systemd is chosen as the init system for a Linux distribution, the init process generates and consumes a root control group ( cgroup ) and acts as a cgroup manager.
Is Podman a cri?
Podman is a tool designed for managing pods and containers without requiring a container daemon. Pods and containers processes are created as children of the Podman tool. Podman does NOT speak CRI.
