kubeadm

将Kubernetes安装到Docker容器里面，使用DinD(Docker in Docker)完成。 kubeadm-dind-cluster A Kubernetes multi-node cluster for developer of Kubernetes and projects that extend Kubernetes. Based on kubeadm and DIND (Docker in Docker). Supports both local workflows and workflows utilizing powerful remote machines/cloud instances for building Kubernetes, starting test clusters and running e2e tests. If you're an application developer, you may be better off with Minikube because it's more mature and less dependent on the local environment, but if you're feeling adventurous you may give kubeadm-dind-cluster a try,

I configured kubernetes cluster with one master and 4 worker nodes using KUBEADM tool IN LOCAL. All nodes are running fine. deployed an app and able access that app from browser. I have tried many ways to create a dashboard using kubectl but i am failed. TRY1: tried directly with the below command: $ sudo kubectl proxy --address="172.20.22.101" -p 8001 tried to access the dashboard using the url http://172.20.22.101:8001/api/v1 , but it is saying unauthorized. TRY2: created dashboard-admin.yaml file with the below content: apiVersion: rbac.authorization.k8s.io/v1beta1 kind: ClusterRoleBinding

I'm experiencing Error Expected HTTP 101 response but was '403 Forbidden' After I setup a new Kubernetes cluster using Kubeadm with a single master and two workers, as I submit a pyspark sample app I encountered below ERROR message: spark-submit command spark-submit --master k8s://master-host:port \ --deploy-mode cluster --name test-pyspark \ --conf spark.kubernetes.container.image=mm45/pyspark-k8s-example:2.4.1 \ --conf spark.kubernetes.pyspark.pythonVersion=3 \ --conf spark.executor.instances=1 \ --conf spark.executor.memory=1000m \ --conf spark.driver.memory=1000m \ --conf spark.executor

I followed Alex Ellis' excellent tutorial that uses kubeadm to spin-up a K8s cluster on Raspberry Pis. It's unclear to me what the best practice is when I wish to power-cycle the Pis. I suspect sudo systemctl reboot is going to result in problems. I'd prefer not to delete and recreate the cluster each time starting with kubeadm reset . Is there a way that I can shutdown and restart the machines without deleting the cluster? Thanks! 来源： https://stackoverflow.com/questions/48362855/is-there-a-best-practice-to-reboot-a-cluster

I did K8s(1.11) cluster using kubeadm tool. It 1 master and one node in the cluster. I applied dashboard UI there. kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml Created service account (followed this link: https://github.com/kubernetes/dashboard/wiki/Creating-sample-user ) apiVersion: v1 kind: ServiceAccount metadata: name: admin-user namespace: kube-system and apiVersion: rbac.authorization.k8s.io/v1beta1 kind: ClusterRoleBinding metadata: name: admin-user roleRef: apiGroup: rbac.authorization.k8s.io kind:

I want to install kube-prometheus on my existing kubernetes cluster(v1.10). Before that, the doc says I need to change the ip address of contrller/scheduler from 127.0.0.1 to 0.0.0.0 . And it also recommand to use kubeadm config upgrade to change these features: controllerManagerExtraArgs: address: 0.0.0.0 schedulerExtraArgs: address: 0.0.0.0 After reading the doc, i tried with the below command, but it didn't work: kubeadm upgrade --feature-gates controllerManagerExtraArgs.address=0.0.0.0 I know i can use kubectl -n kube-system edit cm kubeadm-config to modify configMap directly, just want to

When I provision a Kubernetes cluster using kubeadm and I get my nodes tagged as none. It's a know bug in Kubernetes and currently a PR is in-progress. However, I would like to know if there is an option to add a Role name manually for the node? root@ip-172-31-14-133:~# kubectl get nodes NAME STATUS ROLES AGE VERSION ip-172-31-14-133 Ready master 19m v1.9.3 ip-172-31-6-147 Ready <none> 16m v1.9.3 A node role is just a label with the format node-role.kubernetes.io/<role> You can add this yourself with kubectl label ram dhakne This worked for me: kubectl label node cb2.4xyz.couchbase.com node
