Re: [kubernetes-users] Number of Namespaces

No, there is no technical limit to the number of namespaces. From a practical perspective, I've heard that ~1000 is where there starts to be some scaling issues with the current releases. On Mon, May 14, 2018 at 5:39 AM, wrote: > Hi, > > I'm pretty new to k8s and we've

Re: [kubernetes-users] Best practices for organising/managing namespaces within SaaS product across multiple teams

My usual recommendation is to have highly granular namespaces. One pattern I've seen is that every unique instance of an app has a separate namespace. This allows you to isolate concerns. For example, an API, Database, worker queue, and monitoring for a single app all live in an isolated

Re: [kubernetes-users] k8s networking / cluster size limits confusion

Kuberentes will be giving a /24 to each node, not each pod. Each node will give one IP out of that /24 to a pod it controls. This default means you can have 253 pods-per-node. This of course can be adjust depending on the size of your pods and nodes. This means that you can fully utilize the

Re: [kubernetes-users] Re: Filter the cadvisor metrics

Yes, that is correct. Similar techniques apply for Prometheus. There is a set of rewrite rules that can be used to filter metrics on ingestion, and recording rules to aggregate data. As Matthias says, this kind of policy stuff generally better left to the service reading the data, because it

This sounds like a job that should happen at provisioning time, or by config management software. On Jan 23, 2017 10:00, "Mayank" wrote: > Yeah, my use case is basically change the permissions of the hostPath so > that my pods running as non root can access it. I dont want

Re: [kubernetes-users] Isolated VLANs

In Kubernetes, we're moving to a SDN-style access control system, instead of VLANs. You get better control, without the hassle of moving VLANs around. Take a look at Canal, the overlay network and policy control software: https://github.com/projectcalico/canal On Fri, Jan 20, 2017 at 11:21 PM,

Re: [kubernetes-users] remote deployment

Kubernetes requires all nodes that run pods to have the kubelet running to manage the containers. This also means that everything in the cluster needs to be part of the same overlay network. This can be done "remotely" with overlay software like weaveworks system. But for most practical

Load balancers for bare metal are the same as load balancers for cloud providers. There's not really anything different. On Mon, Nov 21, 2016 at 7:46 AM, Sandeep Srinivasa wrote: > Very very needed! > I would argue that k8s is the kind of disruptor that would replace the
