An issue has been opened to track the fix for the CFS scheduler bug in CoreOS. People using CoreOS to host Kubernetes may want to track this: https://github.com/coreos/bugs/issues/2623

Thanks for sharing @Erik Osterman (Cloud Posse),

The idea was to validate this today with a little working prototype if you have feature ideas let me know.
Currently the main benefit to hub.helm.sh is that you are able to compare two chart versions.
Other Features that I have planned are:
- Notification on releases
- Notification if a new helm chart is added with a keyword you are looking for.

Does any one know how to use kops on gov cloud? I can't get the DNS right. Any help is appreciated
Erik Osterman (Cloud Posse)

I thought it wasn't yet supported

While there are DNS servers in the VPC, there is no Route53 service (API). This breaks many devops tools that make the assumption Route53 is / will be available (kops w/ kubernetes, for example). To be fair, some tools (like kops) provide an alternative to Route53 for bootstrapping the cluster, though our testing found the features to be buggy and not yet production quality. We worked around the need for Route53 by deploying our own self-healing and automated DNS solutions. A future post will dive into the details of our Route53 replacements.

Someone told me of a work around with freeipa with your experience do you think it is a good option?

It works, one of my colleagues is doing it. They said it was janky though. My company is going to be doing a TON of work in the very near future with K8s in GovCloud so I'm looking for more information on the subject as well

I've been unable to find info how to switch a kops 1.13 cluster from single to multi-master; All the documentation I've found provides steps before the switch to etcd-manager. I'm having issues even connecting to etcd with etcdctl

Can anyone point me in the right direction?

If a termination notice is received for an instance that’s running on the cluster, the termination handler begins a multi-step cordon and drain process for the node.

Hi guys,
Trying to parse kubernetes logs with fluent-bit helm chart form here: https://github.com/helm/charts/tree/master/stable/fluent-bit
Stuck in configuring outputs. What I need is to have a few outputs sending logs to different indices into AWS ES based on kubeernetes namespace.
If anyone happened to have worked with this helm or similar issue help is welcomed. 🙂

"fast" in the DoD meaning less than 5 years?

Somebody else go through this list and tell me if any of them sound fishy. I want to see if your list matches my list.

Hello,

What are folks using as their helm chart repository ? I began by using an S3 bucket in our shared AWS account. But would like to hear if there's something better out there in terms of user/developer experience

Hi, does anybody know if images of the OpenShift internal registry could be pulled cluster internally and pushed to an external (like Nexus) repository?

What GitOps tools do people use here. I have been looking into FluxCD and ArgoCD . Interested to hear about other peoples experiences with any other relevant tools.
