k8s集群环境安装kubesphere并查看问题

k8s集群环境安装kubesphere并查看问题

1.安装环境和内容说明

1.1 服务器环境是1个主节点(k8s-master)和2个从节点构成，每台服务器都有k8s基础环境1.17.3版本，从节点都已加入主节点，3台网络都能互通

1.2 CentOS7.x系统自带的3.10.x内核存在一些Bugs，导致运行的Docker、kubernetes不稳定，而且在安装最后步骤导致kubesphere控制台管理页面不能登录，这里先升级到4.4.XX版本，命令如下：

（1）下载内核

rpm -Uvh --enablerepo=elrepo-kernel install -y kernel-lt

（3）设置开机从新内核启动

grub2-set-default "CentOS Linux (4.4.221-1.el7.elrepo.x86_64) 7 (Core)"

（4）重启并查看新内核版本

reboot

uname -r

1.3 以下在k8s-master节点上安装的内容依次为：

helm 2.16.2、tiller 2.16.2、openebs 1.5.0、kubesphere 3.0.0

2.开始安装helm + tiller

2.1 查看master节点是否有污点

kubectl describe node k8s-master | grep Taint

显示： Taints:             node-role.kubernetes.io/master:NoSchedule

2.2 解除污点

kubectl taint nodes k8s-master node-role.kubernetes.io/master:NoSchedule-node/k8s-master untainted

再次查看污点显示：Taints:            

2.3 下载并安装helm 2.16.2

wget -zxvf helm-v2.16.2-linux-amd64.tar.gz

mv linux-amd64/helm /usr/local/bin/helm

2.4 安装tiller

由于Helm默认会去storage.googleapis.com拉取镜像，如果你当前执行的机器不能科学上网（墙）的话可以使用阿里的源来安装：

helm init --upgrade --tiller-image registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.16.2 --stable-repo-url init --service-account=tiller --tiller-image=gcr.io/kubernetes-helm/tiller:v2.16.2 --history-max 300

等待一会，查看pod，tiller状态是Running就是成功了

kubectl get pods --all-namespaces

查看版本，显示Client和Server信息即安装成功

helm version

2.5 创建rbac权限，给tiller授权

新建tiller-rbac.yaml，内容如下

apiVersion: v1 kind: ServiceAccount metadata: name: tiller namespace: kube-system --- apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRoleBinding metadata: name: tiller roleRef: apiGroup: rbac.authorization.k8s.io kind: ClusterRole name: cluster-admin subjects: - kind: ServiceAccount name: tiller namespace: kube-system

应用rbac

kubectl apply -f tiller-rbac.yaml

3.安装openebs

3.1 官网的执行命令无法安装，因为不能下载镜像，可以参考​​This manifest deploys the OpenEBS control plane components, with associated CRs & RBAC rules# NOTE: On GKE, deploy the openebs-operator.yaml in admin context # Create the OpenEBS namespaceapiVersion: v1kind: Namespacemetadata: name: openebs---# Create Maya Service AccountapiVersion: v1kind: ServiceAccountmetadata: name: openebs-maya-operator namespace: openebs---# Define Role that allows operations on K8s pods/deploymentskind: ClusterRoleapiVersion: rbac.authorization.k8s.io/v1beta1metadata: name: openebs-maya-operatorrules:- apiGroups: ["*"] resources: ["nodes", "nodes/proxy"] verbs: ["*"]- apiGroups: ["*"] resources: ["namespaces", "services", "pods", "pods/exec", "deployments", "deployments/finalizers", "replicationcontrollers", "replicasets", "events", "endpoints", "configmaps", "secrets", "jobs", "cronjobs"] verbs: ["*"]- apiGroups: ["*"] resources: ["statefulsets", "daemonsets"] verbs: ["*"]- apiGroups: ["*"] resources: ["resourcequotas", "limitranges"] verbs: ["list", "watch"]- apiGroups: ["*"] resources: ["ingresses", "horizontalpodautoscalers", "verticalpodautoscalers", "poddisruptionbudgets", "certificatesigningrequests"] verbs: ["list", "watch"]- apiGroups: ["*"] resources: ["storageclasses", "persistentvolumeclaims", "persistentvolumes"] verbs: ["*"]- apiGroups: ["volumesnapshot.external-storage.k8s.io"] resources: ["volumesnapshots", "volumesnapshotdatas"] verbs: ["get", "list", "watch", "create", "update", "patch", "delete"]- apiGroups: ["apiextensions.k8s.io"] resources: ["customresourcedefinitions"] verbs: [ "get", "list", "create", "update", "delete", "patch"]- apiGroups: ["*"] resources: [ "disks", "blockdevices", "blockdeviceclaims"] verbs: ["*" ]- apiGroups: ["*"] resources: [ "cstorpoolclusters", "storagepoolclaims", "storagepoolclaims/finalizers", "cstorpoolclusters/finalizers", "storagepools"] verbs: ["*" ]- apiGroups: ["*"] resources: [ "castemplates", "runtasks"] verbs: ["*" ]- apiGroups: ["*"] resources: [ "cstorpools", "cstorpools/finalizers", "cstorvolumereplicas", "cstorvolumes", "cstorvolumeclaims"] verbs: ["*" ]- apiGroups: ["*"] resources: [ "cstorpoolinstances", "cstorpoolinstances/finalizers"] verbs: ["*" ]- apiGroups: ["*"] resources: [ "cstorbackups", "cstorrestores", "cstorcompletedbackups"] verbs: ["*" ]- apiGroups: ["coordination.k8s.io"] resources: ["leases"] verbs: ["get", "watch", "list", "delete", "update", "create"]- apiGroups: ["admissionregistration.k8s.io"] resources: ["validatingwebhookconfigurations", "mutatingwebhookconfigurations"] verbs: ["get", "create", "list", "delete", "update", "patch"]- nonResourceURLs: ["/metrics"] verbs: ["get"]- apiGroups: ["*"] resources: [ "upgradetasks"] verbs: ["*" ]---# Bind the Service Account with the Role Privileges.# TODO: Check if default account also needs to be therekind: ClusterRoleBindingapiVersion: rbac.authorization.k8s.io/v1beta1metadata: name: openebs-maya-operatorsubjects:- kind: ServiceAccount name: openebs-maya-operator namespace: openebsroleRef: kind: ClusterRole name: openebs-maya-operator apiGroup: rbac.authorization.k8s.io---apiVersion: apps/v1kind: Deploymentmetadata: name: maya-apiserver namespace: openebs labels: name: maya-apiserver openebs.io/component-name: maya-apiserver openebs.io/version: 1.5.0spec: selector: matchLabels: name: maya-apiserver openebs.io/component-name: maya-apiserver replicas: 1 strategy: type: Recreate rollingUpdate: null template: metadata: labels: name: maya-apiserver openebs.io/component-name: maya-apiserver openebs.io/version: 1.5.0 spec: serviceAccountName: openebs-maya-operator containers: - name: maya-apiserver imagePullPolicy: IfNotPresent image: openebs/m-apiserver:1.5.0 ports: - containerPort: 5656 env: # OPENEBS_IO_KUBE_CONFIG enables maya api service to connect to K8s # based on this config.

3.2 应用安装

kubectl apply -f openebs1.5.0-install.yaml

3.3 将openebs-hostpath设置为默认的StorageClass

等待openebs命名空间下的pod都创建成功如下：

查看服务

kubectl get sc

设置

kubectl patch storageclass openebs-hostpath -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

再次查看服务多了（default）即可

3.4 再次打上污点

kubectl taint nodes k8s-master node-role.kubernetes.io=master:NoSchedule

4.安装kubesphere

4.1 根据yaml最小化安装

kubectl apply -f apply -f 应用执行后查看日志

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f

4.3 等待漫长安装之后看到成功信息和账号即可

5.通过30880端口访问kubesphere控制台页面出现错误查看

如果出现错误如下：

5.1 查看pod是否都运行成功

kubectl get pods --all-namespaces

5.2 查看ks-controller-manager的运行状态，命令要指定命名空间

kubectl describe pod ks-controller-manager-69b7489b55-sbkr4 --namespace kubesphere-system

状态是Running即可

5.3 查看ks-controller-manager日志，结果发现超时异常

kubectl logs ks-controller-manager-69b7489b55-sbkr4 --namespace kubesphere-system

错误日志

以上错误最终通过升级centos内核到4.4.XX才可以访问，就是文章开头建议先升级内核的原因
