Cloud Native Enthusiasts Weekly: Grafana Open Source Prometheus Long-Term Storage Project Mimir

Open source project recommendation

Grafana Mimir

Grafana Mimir is a new open source project of Grafana Labs to provide persistent storage for Prometheus. The open source license agreement is AGPL-3.0. Grafana has open sourced Cortex before, but Grafana Cloud uses internal commercial storage, so the Grafana team needs to maintain two sets of codes. Maybe it is too tiring to maintain two sets of codes, so the storage used by Grafana Cloud is open sourced, which is Grafana Mimir.

Open Policy Registry

Open Policy Registry is a mirror repository for sharing Open Policy Agent policies, and also provides a CLI tool, you can push/pull various workflows just like using Docker. The mirror repository follows the OCI specification, so cosign can also be used to sign the "mirror" of the policy.

Caddy SSH

Caddy SSH is a modular and extensible SSH Server that is not a standalone service, but a module for Caddy. This project aims to provide a more secure modern SSH server.

Detector for Docker Socket

Detector for Docker Socket is a kubectl plugin to detect if a Docker socket (docker.sock) is mounted on a workload in a Kubernetes cluster. E.g:

 $ kubectl dds --verbose
NAMESPACE       TYPE            NAME                    STATUS
default         deployment      deploy-docker-volume    mounted
default         daemonset       ds-docker-volume        mounted
default         statefulset     ss-docker-volume        mounted
default         job             job-docker-volume       mounted
default         cron            cron-docker-volume      mounted
kube-system     pod             pod-docker-volume       mounted
kube-system     daemonset       aws-node                not-mounted
kube-system     daemonset       ebs-csi-node            not-mounted
kube-system     daemonset       kube-proxy              not-mounted
test1           deployment      deploy-docker-volume    mounted

Qumulo improves DevOps capabilities with new CSI driver

A few days ago, Qumulo announced support for Kubernetes customers with the Container Storage Interface (CSI) driver as a production preview. Now, customers innovating with Kubernetes don't have to set up the storage interface every time they bring up or shut down a cluster -- the process is automated and provides maximum Qumulo analytics for containerized applications so customers can easily understand what's going on with their stored data .

[etcd v3.5.[0-2] version is no longer recommended for production]( https://github.com/etcd-io/etcd/tree/main/CHANGELOG "etcd v3.5 is no longer recommended. [0-2] version for production")

The minimum recommended versions of etcd to run in production are 3.3.18+, 3.4.2+.

The etcd v3.5.[0-2] release is no longer recommended for production use due to data corruption issues.

Data corruption issues with v3.5: Running etcd v3.5.2, v3.5.1, and v3.5.0 under heavy load can cause data corruption issues. If the etcd process is killed, occasionally some committed transactions are not reflected on all members.

Kubernetes releases 2022 release cycle survey

The survey was designed to help Kubernetes determine how often a release should be released, and the Kubernetes project committed to surveying users and contributors to determine whether a newer schedule of 3 releases per year would be optimal. Whether you are an individual or an organization representing your work, you can fill out this survey to provide feedback.
