K8s 安装 Kubespere
配置 Kubernetes 集群中的默认存储类
环境 centos 7
安装 nfs
服务端运行
# centos
yum install -y nfs-utils rpcbind
#
# ubuntu
sudo apt-get install -y nfs-kernel-server
# 创建共享存储文件夹
mkdir /nfs
# 配置nfs
vi /etc/exports
/nfs *(rw,async,no_root_squash)
# 启动服务
# centos
systemctl start rpcbind
systemctl enable rpcbind
systemctl enable nfs && systemctl restart nfs
#
# ubuntu
sudo /etc/init.d/rpcbind restart
sudo /etc/init.d/nfs-kernel-server restart
# 查看服务状态
# centos
systemctl status rpcbind
systemctl status nfs
# 查看可用的 nfs 地址
showmount -e localhost
node 上执行
# 安装nfs-utils和rpcbind
# centos
yum install -y nfs-utils rpcbind
# ubuntu
sudo apt-get install -y nfs-common
# 创建挂载的文件夹
mkdir -p /nfs/data
# 挂载nfs
mount -t nfs 192.168.2.80:/nfs /nfs/data
编写 Deployment
vim nfs-client.yaml
kind: Deployment
apiVersion: apps/v1
metadata:
name: nfs-client-provisioner
spec:
replicas: 1
selector:
matchLabels:
app: nfs-client-provisioner

编写 SA
nfs-client-sa.yaml
apiVersion: v1
kind: ServiceAccount
metadata:

创建 StorageClass 对象
nfs-client-class.yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: course-nfs-storage
provisioner: fuseim.pri/ifs # or choose another name, must match deployment's env PROVISIONER_NAME'
allowVolumeExpansion: true
创建资源对象
kubectl create -f nfs-client.yaml
kubectl create -f nfs-client-sa.yaml
kubectl create -f nfs-client-class.yaml
# 设置这个 course-nfs-storage 的 StorageClass 为 Kubernetes 的默认存储后端
kubectl patch storageclass course-nfs-storage -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
安装 kubespere
部署 KubeSphere
v3.3.0 版本
# 安装
kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.3.0/kubesphere-installer.yaml
kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.3.0/cluster-configuration.yaml
# 查看安装日志
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l 'app in (ks-install, ks-installer)' -o jsonpath='{.items[0].metadata.name}') -f
# 验证
kubectl get po -A
# 以及浏览器访问 IP:30880 默认帐户和密码 (admin/P@88w0rd)
node-exporter 起不来
之前节点装了 node-exporter ，端口冲突了
prometheus PVC一直处于Pending状态
# 修改apiserver的yaml文件
$ vim /etc/kubernetes/manifests/kube-apiserver.yaml
spec:
containers:
- command:
- kube-apiserver
- --feature-gates=RemoveSelfLink=false
# 执行apiserver文件（twice）
$ kubectl apply -f /etc/kubernetes/manifests/kube-apiserver.yaml
