Timoni
is a
package manager for Kubernetes, powered by CUE and inspired by Helm. The Timoni project strives to improve the UX of authoring Kubernetes configs. Instead of mingling Go templates with YAML like Helm, or layering YAML on top of each-other like Kustomize, Timoni relies on cuelang's type safety, code generation and data validation features to offer a better experience of creating, packaging and delivering apps to Kubernetes https://github.com/stefanprodan/timoni #k8s #kubernetes #cuelang #helm #yaml #kustomize

Repost from YIGAL LEVIN
Азербайджанський Kanal13 проілюстрував заяву керівника Головного управління бойових ударних систем ЗСУ, полковника Сергія Баранова про українську систему виявлення та винищення ворогів, яку на заході вже охрестили, як "Killnet" ("Сітка смерті") ЗСУ.
Ми писали про неї вчора.

Performance Evaluation of Container Runtimes
The co-location of containers on the same host leads to significant performance concerns in the multi-tenant environment such as the cloud. These concerns are raised due to an attempt to maximize host resource utiliza- tion by increasing the number of containers running on the same host. The selection of a container runtime becomes critical in the case of strict performance requirements. In the scope of the study, two commonly used runtimes were evaluated: containerd (industry standard) and CRI-O (reference implementation of the CRI) on two different Open Container Initiative (OCI) runtimes: runc (default for most container runtimes) and gVisor (highly secure alternative to runc). Evaluation aspects of container runtimes include the performance of running containers, the performance of container runtime operations, and scalability. A tool called Touch- Stone was developed to address these evaluation aspects. The tool uses the CRI standard and is pluggable into any Kubernetes-compatible container runtime. Performance results demonstrate the better performance of containerd in terms of CPU usage, memory latency and scalability aspects, whereas file system operations (in particular, write operations) are performed more efficiently by CRI-O.
