K8s集群部署及Kubesphere安装
K8s集群部署及Kubesphere安装
K8s集群部署
kubeadm 是官方社区推出的一个用于快速部署 kubernetes 集群的工具。 这个工具能通过两条指令完成一个 kubernetes 集群的部署：
-
创建一个 Master 节点 $ kubeadm init
-
将一个 Node 节点加入到当前集群中 $ kubeadm join
一、前置环境要求
- 一台兼容的 Linux 主机。Kubernetes 项目为基于 Debian 和 Red Hat 的 Linux 发行版以及一些不提供包管理器的发行版提供通用的指令
- 每台机器 2 GB 或更多的 RAM （如果少于这个数字将会影响你应用的运行内存)
- 2 CPU 核或更多
- 集群中的所有机器的网络彼此均能相互连接(公网和内网都可以)
- 节点之中不可以有重复的主机名、MAC 地址或 product_uuid。请参见这里了解更多详细信息。
- 开启机器上的某些端口。请参见这里 了解更多详细信息。
- 禁用交换分区。为了保证 kubelet 正常工作，你 必须 禁用交换分区。
kubesphere选用最新版本为：3.20，与之相配套的k8s版本为1.21.3（1.22.x实验性支持就不用了）
二、部署步骤
- 在所有节点上安装 Docker 和 kubeadm
- 部署 Kubernetes Master
- 部署容器网络插件
- 部署 Kubernetes Node，将节点加入 Kubernetes 集群中
三、环境准备
按照前置环境要求准备三台虚拟机并进行配置，这里使用vmware创建最小化Centos操作系统，并进行克隆处理。
| 节点名称 | IP地址 | 用途 |
|---|---|---|
| k8s-node1 | 192.168.63.10 | 作为Master节点使用 |
| k8s-node2 | 192.168.63.11 | 作为Node节点使用 |
| k8s-node3 | 192.168.63.12 | 作为Node节点使用 |
3.1 前置条件设置（所有节点）：
1、开启root密码访问权限（一般不用改）
-
vi /etc/ssh/sshd_config 修改 PasswordAuthentication yes/no 重启服务 service sshd restart
2、修改主机IP地址
vi /etc/sysconfig/network-scripts/ifcfg-ens33
3、关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
4、关闭 selinux
sed -i 's/enforcing/disabled/' /etc/selinux/config
setenforce 0
5、关闭swap
swapoff -a #临时
sed -ri 's/.*swap.*/#&/' /etc/fstab #永久
free -g #验证，swap 必须为 0；
6、添加主机名与 IP 对应关系
vi /etc/hosts
192.168.63.10 k8s-node1
192.168.63.11 k8s-node2
192.168.63.12 k8s-node3
7、修改主机名
vi /etc/hostname
8、将桥接的 IPv4 流量传递到 iptables 的链
cat > /etc/sysctl.d/k8s.conf << EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
sysctl --system
3.2 所有节点安装 Docker、kubeadm、kubelet、kubectl
3.2.1 安装 docker（所有节点）
可参考：
3.2.2安装kubeadm、kubectl、kubelet（所有节点）
- 为了加速yum安装，需提前配置一下阿里云yum源加速地址。
cat > /etc/yum.repos.d/kubernetes.repo << EOF
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg
https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF
- 安装
yum list|grep kube
yum install -y kubelet-1.21.3 kubeadm-1.21.3 kubectl-1.21.3
systemctl enable kubelet
systemctl start kubelet
3.2.3配置k8s master节点
kubeadm init \ --apiserver-advertise-address=masterIP地址 \ --image-repository registry.cn-hangzhou.aliyuncs.com/google_containers \ --kubernetes-version v1.21.3 \ --service-cidr=10.125.0.0/16 \ --pod-network-cidr=10.150.0.0/16
- masterIP地址：指定需要初始化为master节点的IP地址
- image-repository：指定镜像加速地址
- service-cidr：集群内服务之间路由地址
- pod-network-cidr：集群内pod之间通讯的有效IP地址
...以上内容忽略
Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
Alternatively, if you are the root user, you can run:
export KUBECONFIG=/etc/kubernetes/admin.conf
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
You can now join any number of control-plane nodes by copying certificate authorities
and service account keys on each node and then running the following as root:
kubeadm join 192.168.63.10:6443 --token ii44ya.n4ryb3yka0q09fq3 \
--discovery-token-ca-cert-hash sha256:67318db78eef549400d515ed239ca3dbf85d5195e4ba6c13b61854f497278b39 \
--control-plane
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.63.10:6443:6443 --token ii44ya.n4ryb3yka0q09fq3 \
--discovery-token-ca-cert-hash sha256:67318db78eef549400d515ed239ca3dbf85d5195e4ba6c13b61854f497278b39
提前复制创建好的令牌，令牌2小时之内有效。如果过期可以使用以下命令生成token：
kubeadm token create --ttl 0 --print-join-command
按照提示，执行以下命令：
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
3.2.4 Master安装Pod网络插件
Flannel 是一个非常简单的能够满足 Kubernetes 所需要的覆盖网络。使用Flannel作为k8s的网络附加组件。
kubectl apply -f \
https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
不出意外上边的命令是执行不成功的，查看pod的状态发现会是Init:ImagePullBackOff，原因是下载的镜像为quay.io/coreos/flannel:v0.12.0-amd64，由于quary.io国内访问不了，所以镜像也就下载不成功。为了成功安装安装Flannel，需要手动安装，具体步骤如下：
-
去https://github.com/coreos/flannel/releases下载flannel镜像
-
导入镜像
docker load < flanneld-v0.12.0-amd64.docker -
稍等片刻k8s会自动重新安装，Flannel状态变为Running则代表成功
[root@k8s-node1 ~]# kubectl get pod -n kube-system
NAME READY STATUS RESTARTS AGE
coredns-6f6b8cc4f6-qdkzr 1/1 Running 1 22h
coredns-6f6b8cc4f6-shkd9 1/1 Running 1 22h
etcd-k8s-node1 1/1 Running 1 22h
kube-apiserver-k8s-node1 1/1 Running 1 22h
kube-controller-manager-k8s-node1 1/1 Running 1 22h
kube-flannel-ds-amd64-8vhz7 1/1 Running 1 20h
3.2.5 将两外两台机器加入集群
在另外两台机器分别执行以下命令，等待节点加入集群。
kubeadm join 192.168.63.10:6443:6443 --token ii44ya.n4ryb3yka0q09fq3 \
--discovery-token-ca-cert-hash sha256:67318db78eef549400d515ed239ca3dbf85d5195e4ba6c13b61854f497278b39
等待几分钟后，所有阶段状态为Ready，则代表集群搭建成功。输出日志类似如下：
[preflight] Running pre-flight checks
... (log output of join workflow) ...
Node join complete:
* Certificate signing request sent to control-plane and response
received.
* Kubelet informed of new secure connection details.
Run 'kubectl get nodes' on control-plane to see this machine join.
PS：如果加入集群失败，则使用
kubeadm reset重置安装状态后，再执行上述命令即可。
[root@k8s-node1 ~]# kubectl get nodes
NAME STATUS ROLES AGE VERSION
k8s-node1 Ready control-plane,master 21h v1.21.3
k8s-node2 Ready <none> 20h v1.21.3
k8s-node3 Ready <none> 20h v1.21.3
至此，K8s集群安装完毕，可以安装简单的应用进行测试，如nginx、tomcat等。
Kubesphere安装
一、安装Helm和Tiller
1、安装Helm（master节点）
curl -L https://git.io/get_helm.sh | bash
不出意外，上述命令仍然不能成功执行，还是由于网络原因，故需要手动安装Helm。
-
下载Helm压缩包并移动到指定位置
tar -zxvf helm-v2.16.3-linux-amd64.tar.gz mv linux-amd64/helm /usr/local/bin/helm helm version看到如下信息则安装成功：
Client: &version.Version{SemVer:"v2.16.3", GitCommit:"1ee0254c86d4ed6887327dabed7aa7da29d7eb0d", GitTreeState:"clean"}
2、安装Tiller
-
创建授权文件helm-rbac.yaml
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 -
执行
kubectl apply -f helm-rbac.yaml -
安装Tiller
helm init --service-account tiller --upgrade --tiller-image=jessestuart/tiller:v2.16.3 --history-max 300 --stable-repo-url https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts -
验证版本
helm versionClient: &version.Version{SemVer:"v2.16.3", GitCommit:"1ee0254c86d4ed6887327dabed7aa7da29d7eb0d", GitTreeState:"clean"} Server: &version.Version{SemVer:"v2.16.3", GitCommit:"1ee0254c86d4ed6887327dabed7aa7da29d7eb0d", GitTreeState:"clean"}
二、安装OpenEBS
1、确定master节点是否有taint
kubectl describe node k8s-node1 | grep Taint
kubectl taint nodes k8s-node1 node-role.kubernetes.io/master:NoSchedule-
2、安装OpenEBS
kubectl apply -f https://openebs.github.io/charts/openebs-operator-1.5.0.yaml
不出意外，由于网络原因，上述命令执行成功，但查看所有pod状态，发现镜像都无法下载失败。需手动安装，具体步骤如下：
-
下载所需docker镜像(附件中有)
-
加载镜像到三个节点
docker load < xx.tar -
修改yaml文件（附录中的无需修改）
-
删除部署失败的deployment和daemonset
kubectl delete deployment maya-apiserver openebs-admission-server openebs-localpv-provisioner openebs-provisioner openebs-snapshot-operator openebs-ndm-operator -n openebskubectl delete daemonset openebs-ndm -n openebs -
重新执行
kubectl apply -f openebs-operator-1.5.0.yaml，等待安装成功。
如果某个Pod安装失败，可以使用kubectl describe pod [podname] -n [namespace]查看日志。
-
查看效果
kubectl get sc -n openebsNAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE openebs-device openebs.io/local Delete WaitForFirstConsumer false 12h openebs-hostpath (default) openebs.io/local Delete WaitForFirstConsumer false 12h openebs-jiva-default openebs.io/provisioner-iscsi Delete Immediate false 12h openebs-snapshot-promoter volumesnapshot.external-storage.k8s.io/snapshot-promoter Delete Immediate false 12h -
将 openebs-hostpath 设置为 默认的 StorageClass
kubectl patch storageclass openebs-hostpath -p \ '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}' -
至此，OpenEBS 的 LocalPV 已作为默认的存储类型创建成功。由于在文档开头手动去掉 了 master 节点的 Taint，我们可以在安装完 OpenEBS 后将 master 节点 Taint 加上，避 免业务相关的工作负载调度到 master 节点抢占 master 资源
kubectl taint nodes k8s-node1 node-role.kubernetes.io=master:NoSchedule
三、最小化安装
1、执行命令
kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.0/kubesphere-installer.yaml
kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.0/cluster-configuration.yaml
2、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
3、验证
- 安装完成后会有如下日志：
