Hi, It’s possible to manually adjust the file /var/nutanix/etc/kubernetes/manifests/kube-apiserver.yaml and apply this update into the kubernetes cluster? I tried to adjust and after run: sudo systemctl daemon-reload && sudo systemctl restart kubelet-master But when I describe the kube-api pod I see that the adjusts are not applied. Anibal

For those running Docker, check out > Nutanix Container Volume Plug-in on the Docker store. Nutanix Volume Plugin enables container persistent storage. Try it out today and let me know your experience.
Just wanted to share how we are renewing the kubeconfig from the command line. Background: In our organization it was considered a bit clumsy to download the kubeconfig from the Karbon UI. We love the command line and wanted a quick’n’easy way to renew the authentication token. The solution: We created a docker image that contains the “karbonctl” binary and a wrapper script. The Dockerfile was also included into our CI/CD pipeline to automate the image creation. The wrapper script does two things: karbonctl login --pc-ip prism.nightingale.nu --pc-username “$1” karbonctl cluster kubeconfig --cluster-name “$2” >”$3” The commands that the end user run: docker run --rm -it -v “$(pwd)”:/tmp docker.registry.local/karbonctl:latest <login> mycluster /tmp/karbon.cfg export KUBECONFIG=”$(pwd)/karbon.cfg”
Hi, Someone know if we can enable PodPreset on the Karbon? (https://kubernetes.io/docs/concepts/workloads/pods/podpreset/#enable-pod-preset) Basically my cluster are under a Proxy and I can’t deploy application under Pod because they need to access the internet, with the PodPreset I can configure the proxy information like this https://docs.gitlab.com/ee/topics/autodevops/index.html#installing-helm-behind-a-proxy
Hi,I’m trying to explore kubernetes by deploying Development Cluster. But it only stuck at 8% and eventually failed with notification (Internal Error : Failed to deploy ntnx dvp).Here is my detailSegment 192.168.2.x for Guest VM,PC,AOS and AHV. Segment 192.168.3.x for Kubernetes cluster itself (DHCP Enabled)Each segment can ping each other and all those segments are able to access the internet.Here is the detail of the temporary deployed Karbon VM (After failed deploying, the VM got deleted automatically)I’ve been reading someone posted same problem like mine, and it solved because of the VM previously unable to access the internet. But mine is able to access internet, PC and the Internal Nutanix.Perhaps someone can enlighten me what did i do wrong?-Able to pull newest docker image-Able to ping Prism Central (192.168.2.11)-Able to ping CVM (192.168.2.2)-Able to access internetDeploying Cluster stuck at 8%Deleting VM after failure deploymentNotification Internal Error : Failed to deploy
Hello, After a new deployment, I downloaded the kubeconfig and upon trying to approve a Certificate Signing Request (CSR), the csr just sits in an approved state, but never becomes Issued. Is there a restriction or something on the default-kubernetes-<clustername> user that I might not be familiar with? That or maybe my process is wrong, its odd that it just sits in an Approved state. Any help is appreciated!
Hi all We have karbon clusters running in our Nutanix environment, and I noticed the timezone in the Karbon cluster is not the same as that in other VMs on the Nutanix cluster. The time zone set for the Nutanix cluster is SAST (UTC +2), and the Karbon VMs timezone is UTC (UTC +0). The UTC+0 timezone is only on the Karbon Nodes. It seems it doesn’t use the Nutanix Cluster’s timezone, our logs are 2 hours behind on Karbon Clusters(all 3 cluster). Is there a way to change the timezone for Karbon?
With the release of Nutanix Karbon TP, PC 5.9, you may want to deploy some of the traditional addons like Kubernetes Dashboard with Heapster. This post walks you through the process to successfully deploy the Kubernetes Dashboard addon. Before you can start with the deployment of the addon you need a working Kubernetes cluster and the kubectl CLI-tool. The steps to follow are: Deploy Heapster Deploy Kubernetes Dashboard Connect to Kubernetes Dashboard Deploying HeapsterFrom Heapster website: Heapster enables Container Cluster Monitoring and Performance Analysis for Kubernetes (versions v1.0.6 and higher), and platforms which include it. Heapster is deprecated. Consider using metrics-server and a third party metrics pipeline to gather Prometheus-format metrics instead. See the deprecation timeline for more information on support. The reason of using Heapster is because: Currently only Heapster integration is supported with Kubernetes Dashboard, however t
What is Karbon? Nutanix Karbon is a curated turnkey offering that provides simplified provisioning and operations of Kubernetes clusters. Kubernetes is an open source container orchestration system for deploying and managing container-based applications. The Karbon web console simplifies the deployment and management of Kubernetes clusters with a simple GUI and built-in event monitoring tools. There are built-in add-ons such as Kibana and Prometheus for parsing logs and monitoring alert triggering mechanism in you cluster. Using Karbon you can: Deploy Kubernetes clusters. Use Nutanix Volumes and Nutanix Files storage for your applications. Manage Kubernetes cluster resources. Upgrade your Kubernetes deployment. Ensure high-availability. To set up your Karbon environment, perform the following tasks: Enable Karbon through Prism Central, Enabling Karbon Download an image, see OS Images Create clusters, see Creating a Cluster Download the kubeconfig, Downloading the Kubeconfig Configure
Xi Epoch generates live application maps to provide instantaneous visibility into your application health without any code instrumentation. Epoch provides visibility into the interactions between components in distributed architectures, without dependency on specific language or framework implementation. As a result, operations team can quickly ensure reliability and availability of any application in any cloud environment. The picture below is showing two different Kubernetes Clusters, Docker Enterprise and Nutanix Karbon. The collectors are deployed as daemon sets so they can be deployed to any Kubernetes cluster to start monitoring your applications. Epoch collectors can be run in both containerized as well as non-containerized environments. Only one collector is needed per host (VM or bare metal OS). Below is YugaDB running Cassandra commands and Epoch is able to look at the traffic and report on how fast commands are happening and even give the most requested queries.
Hi, someone have experience integrating GitLab with Karbon? Basically I’m looking for automatic deployment from gitlab to karbon.
Hi all, I tried to deploy a Karbon Development Cluster by using Karbon API, but I encounter an error with authentication. {"message_list":{"Unauthorized":"Failed to get authentication info"},"status_code":401} The command for calling Karbon API is : curl -k -X POST -d @create-cluster-dev.json --header "Content-Type: application/json" --header "Accept: application/json" --user $NUTANIX_USER:$NUTANIX_USER_PASS "https://xxx.xxx.xxx.xxx:9440/karbon/acs/k8s/cluster" When I try to use other Prism API command, like cluster or vm with these command below,, everything works fine, so I don’t think that my login/password are wrong. I haven’t seen much more into nutanix log file, but maybe i’m looking at the wrong place (/data/logs). curl -k -X POST -d @nutanix-list-cluster.json --header "Content-Type: application/json" --header "Accept: application/json" --user $NUTANIX_USER:$NUTANIX_USER_PASS "https://xxx.xxx.xxx.xxx:9440/api/nutanix/v3/clusters/list" Has anyone encountered th
Hi, My company have a internal CA certificate chain and I need to install the internal ca.crt on Karbon, it’s possible? Use case, install a pod using kubectl from a internal registry are not possible due they didn’t know the root CA authority installed at the registry server. Anibal
I'm testing Karbon. I'm very basic level. I can't make it through the karbon configure testing, so I'll ask you for help. I've upgraded Karbon to the latest version through LCM. After that, I set it up through "Create Kubernets Cluster." That's the problem from here. In the end, an error occurs in the "Deployment Failed" status section. Deploying 8% has an error. I looked up various information. I looked it up, and I think you should setting Proxy http and ERCD. How can setting? Please explain in detail the reason why Karbon can't be distributed. Thank you.
We want to test Nutanix's Karbon, when I click the download centos button, nothing happens.
I'm trying to configure a new Kubernetes cluster using Karbon. When I get to the stage of configuring the storage class, I'm prompted for a user name and password. I'm not sure which user I should be entering here, as the few I've tried don't seem to work. The cluster setup tutorial video shows the username `admin`, which seems to suggest using a very highly privileged user, which seems unnecessary to me. How can I create a user with the minimum privileges necessary for the storage class?
