Kubernetes

Kubernetes (commonly referred to as "K8s") is an open source system for automating deployment, scaling and management of containerized applications originally designed by Google and donated to the Cloud Native Computing Foundation. It aims to provide a "platform for automating deployment, scaling, and operations of application containers across clusters of hosts". It supports a range of container tools, including Docker.

Cgroups plugin supports only proportional and max Block IO policies. We should support BFQ scheduler as well. Disk stats for the scheduler are in blkio.bfq.io_service_bytes
and blkio.bfq.io_serviced
files.

Hi, I am using minikube v1.18.1 on Hyper-V (Microsoft Windows 10 Enterprise)
I recently tried to uninstall minikube and reinstall it.
Steps to reproduce the issue:
- I remove the .minikube directory manually (I know I shouldn’t have), only one file remain : a snapshot file .vmcx, probably the configuration file of my previous VM.
- I added a new Hyper-V switch under the "virtual

Helm documentation states the following:
-1) (k8s) metadata.name is restricted to a maximum length of 63 characters because of limitations to the DNS system
-2) For that reasons, release names are (DNS labels that are) limited to 53 characters
Statement 1) is not correct.
k8s does not impose a max length of 63 characters on resource names.
The actual max length for a resource name is 253 c

).
One of the AWS China regions now supports Route53: https://aws.amazon.com/about-aws/whats-new/2020/05/amazon-route-53-is-now-available-in-AWS-china-region/
If someone with an AWS China account can try creating a cluster using Route53 rather than gossip k8s.local and update docs/aws-china.md with their findings that would be much appreciated. Also identify any changes needed to be made in Kops t

Currently validating checksums requires lots of knowledge on the part of the caller. We should expose optional checksum validation in our existing validation functions e.g. IPv4.IsValid
.
header.UDP and header.TCP don't currently have these functions; we should add them.
The container-debug-support images uses skaffold build
to build and test images. These builds don't have a cluster available and so a plain skaffold build
causes Skaffold to attempt to build and push images, which fails. So we explicitly configure build.local.push: false
so that the images are only built to the local Docker daemon.

Hi,
I see that there is nothing in the kargo repo related to docker login
stuff and more precisely nothing about the ability to make kubernetes pull images from private registries such as ECR.
I have a solution for this that currently works for ECR and CoreOS and that could be extended to different registries solutions (azure one, custom private registry on premi

This is a sub-issue from #5494.
We need to remove any f"strings"
from the backend of the Jupyter web app in order to be able to use lower versions from Python 3.6 to run it.
