背景
| 类型 | 版本 |
|---|---|
| 操作系统 | CentOS Linux release 7.6.1810 (AltArch) |
| 内核 | Linux master 4.18.0-80.7.2.el7.aarch64 |
| 硬件配置 | 8核16G内存 * 2台 |
| 计算机名 | master、node1 |
| K8S版本 | 1.14.2 |
| 计算机名 | 公网IP | 私网IP |
|---|---|---|
| master | 116.63.180.97 | 192.168.0.113 |
| node1 | 116.63.177.54 | 192.168.0.226 |
说明：
- 搭建K8s集群，每台节点均需要按照文档安装Docker及K8s的全部组件。
- 为验证集群搭建功能，至少需要两个节点。如果要验证亲和性调度功能，至少需要三台节点，安装配置工作在每台节点都需要执行。
- Master为集群管理节点，node1为集群计算节点。
一、配置华为云yum源
1.1 配置华为云yum源。

说明：
若没有找到需要的k8s版本，可自行配置阿里yum源
1.2 刷新yum缓存。
<span class="hljs-attribute">yum</span> makecache<span class="hljs-attribute">yum</span> makecache
yum makecache
二、安装配置K8S
主节点和计算节点都需要安装配置K8s。
2.1 安装Docker
2.1.1 安装yum-utils软件包并设置稳定的存储库。
<span class="hljs-attr">yum</span> <span class="hljs-string">install -y yum-utils</span><span class="hljs-meta">yum-config-manager</span> <span class="hljs-string">\ --add-repo \ https://download.docker.com/linux/centos/docker-ce.repo</span><span class="hljs-attr">yum</span> <span class="hljs-string">install -y yum-utils</span>
<span class="hljs-meta">yum-config-manager</span> <span class="hljs-string">\
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo</span>yum install -y yum-utils
yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
2.1.2 安装特定版本Docker
要安装特定版本的Docker Engine，可以先通过命名查看存储库，列出可用版本，然后选择并安装：
yum <span class="hljs-built_in">list</span> docker-ce --showduplicates | sort -ryum <span class="hljs-built_in">list</span> docker-ce-cli --showduplicates | sort -ryum <span class="hljs-built_in">list</span> docker-ce --showduplicates | sort -r
yum <span class="hljs-built_in">list</span> docker-ce-cli --showduplicates | sort -r
yum list docker-ce --showduplicates | sort -r
yum list docker-ce-cli --showduplicates | sort -r
然后根据版本号安装（本文选择），例如：
<span class="hljs-attribute">yum</span> install docker-ce-<span class="hljs-number">18</span>.<span class="hljs-number">09</span>.<span class="hljs-number">9</span>-<span class="hljs-number">3</span>.el<span class="hljs-number">7</span> docker-ce-cli-<span class="hljs-number">18</span>.<span class="hljs-number">09</span>.<span class="hljs-number">9</span>-<span class="hljs-number">3</span>.el<span class="hljs-number">7</span> containerd.io<span class="hljs-attribute">yum</span> install docker-ce-<span class="hljs-number">18</span>.<span class="hljs-number">09</span>.<span class="hljs-number">9</span>-<span class="hljs-number">3</span>.el<span class="hljs-number">7</span> docker-ce-cli-<span class="hljs-number">18</span>.<span class="hljs-number">09</span>.<span class="hljs-number">9</span>-<span class="hljs-number">3</span>.el<span class="hljs-number">7</span> containerd.io
yum install docker-ce-18.09.9-3.el7 docker-ce-cli-18.09.9-3.el7 containerd.io
也可以安装最新版，例如直接使用方式，本文选择的不是最新版本，安装的是指定版本18.09
<span class="hljs-selector-tag">yum</span> <span class="hljs-selector-tag">install</span> <span class="hljs-selector-tag">docker-ce</span> <span class="hljs-selector-tag">docker-ce-cli</span> <span class="hljs-selector-tag">containerd</span><span class="hljs-selector-class">.io</span><span class="hljs-selector-tag">yum</span> <span class="hljs-selector-tag">install</span> <span class="hljs-selector-tag">docker-ce</span> <span class="hljs-selector-tag">docker-ce-cli</span> <span class="hljs-selector-tag">containerd</span><span class="hljs-selector-class">.io</span>
yum install docker-ce docker-ce-cli containerd.io
2.1.3 安装完成启动
<span class="hljs-attribute">systemctl</span> start docker<span class="hljs-attribute">systemctl</span> start docker
systemctl start docker
2.1.4 通过docker version查看版本

三、部署K8S集群
3.1 配置hosts文件
主节点和计算节点都需要配置hosts文件。
执行vi /etc/hosts命令，修改hosts文件，添加集群所有节点的ip及hostname信息。
<span class="hljs-attribute">192</span>.<span class="hljs-number">168</span>.<span class="hljs-number">0</span>.<span class="hljs-number">113</span> master master<span class="hljs-attribute">192</span>.<span class="hljs-number">168</span>.<span class="hljs-number">0</span>.<span class="hljs-number">226</span> node<span class="hljs-number">1</span> node<span class="hljs-number">1</span><span class="hljs-attribute">192</span>.<span class="hljs-number">168</span>.<span class="hljs-number">0</span>.<span class="hljs-number">113</span> master master
<span class="hljs-attribute">192</span>.<span class="hljs-number">168</span>.<span class="hljs-number">0</span>.<span class="hljs-number">226</span> node<span class="hljs-number">1</span> node<span class="hljs-number">1</span>
192.168.0.113 master master
192.168.0.226 node1 node1
每台节点的/etc/hosts文件都要修改。
3.2 配置主节点(master)
说明：重复搭建集群时，请先执行kubeadm reset命令，清除旧的K8s集群设置。
在主节点上执行集群初始化命令。
3.2.1 在主节点上执行集群初始化命令
<span class="hljs-attribute">kubeadm</span> init --kubernetes-version=<span class="hljs-number">1</span>.<span class="hljs-number">14</span>.<span class="hljs-number">2</span> --service-cidr=<span class="hljs-number">10.1.0.0</span>/<span class="hljs-number">16</span> --pod-network-cidr=<span class="hljs-number">10.244.0.0</span>/<span class="hljs-number">16</span><span class="hljs-attribute">kubeadm</span> init --kubernetes-version=<span class="hljs-number">1</span>.<span class="hljs-number">14</span>.<span class="hljs-number">2</span> --service-cidr=<span class="hljs-number">10.1.0.0</span>/<span class="hljs-number">16</span> --pod-network-cidr=<span class="hljs-number">10.244.0.0</span>/<span class="hljs-number">16</span>
kubeadm init --kubernetes-version=1.14.2 --service-cidr=10.1.0.0/16 --pod-network-cidr=10.244.0.0/16
当看到如下信息时代表初始化成功

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
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/
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.0.113:6443 --token all7y6.hxs2yemaucku9dct \
--discovery-token-ca-cert-hash sha256:7e1b11d2715fd87d8aeec9a1924c87b68d36da35392ccee57b0581993dfeb821
黄框信息表示主节点配置集群需要执行的命令，红框信息表示计算节点加入集群的token命令，请保存该段命令。
说明：
- 计算节点不需要执行集群初始化操作。
- 如果在主节点初始化的时候提示：
/proc/sys/net/bridge/bridge-nf-call-iptables contents are not set to 1
可以通过执行echo 1 > /proc/sys/net/bridge/bridge-nf-call-iptables命令将其置为1（vim不可修改此文件）。- 执行该操作时，建议排查是否有配置代理（执行env查看），避免kubeadm init初始化超时失败，删除代理的操作：
export -n http_proxy
export -n https_proxy
export -n no_proxy
--pod-network-cidr > 3.选项用于指定kubernetes网络可以使用的IP地址段，由于后续使用Flannel网络插件，该插件固定使用的IP段为：10.244.0.0/16 。

这样我们K8S集群就搭建完成了。
四、（选配）安装Kubernetes Dashboard插件
主节点上操作即可
4.1 用openssl生成自签证书(有第三方证书可跳过)
生成证书请求的key
<span class="hljs-attribute">openssl</span> genrsa -out dashboard.key <span class="hljs-number">2048</span><span class="hljs-attribute">openssl</span> genrsa -out dashboard.key <span class="hljs-number">2048</span>
openssl genrsa -out dashboard.key 2048
生成证书请求
openssl req -<span class="hljs-keyword">new</span> -out dashboard.csr -<span class="hljs-keyword">key</span> dashboard.<span class="hljs-keyword">key</span> -subj <span class="hljs-comment">'/CN=<span class="hljs-doctag"><your_ip></span>'</span>openssl req -<span class="hljs-keyword">new</span> -out dashboard.csr -<span class="hljs-keyword">key</span> dashboard.<span class="hljs-keyword">key</span> -subj <span class="hljs-comment">'/CN=<span class="hljs-doctag"><your_ip></span>'</span>
openssl req -new -out dashboard.csr -key dashboard.key -subj '/CN=<your_ip>'
<your_ip>换成自己的ip或域名。
生成自签证书
<span class="hljs-selector-tag">openssl</span> <span class="hljs-selector-tag">x509</span> <span class="hljs-selector-tag">-days</span> 3650 <span class="hljs-selector-tag">-req</span> <span class="hljs-selector-tag">-in</span> <span class="hljs-selector-tag">dashboard</span><span class="hljs-selector-class">.csr</span> <span class="hljs-selector-tag">-signkey</span> <span class="hljs-selector-tag">dashboard</span><span class="hljs-selector-class">.key</span> <span class="hljs-selector-tag">-out</span> <span class="hljs-selector-tag">dashboard</span><span class="hljs-selector-class">.crt</span><span class="hljs-selector-tag">openssl</span> <span class="hljs-selector-tag">x509</span> <span class="hljs-selector-tag">-days</span> 3650 <span class="hljs-selector-tag">-req</span> <span class="hljs-selector-tag">-in</span> <span class="hljs-selector-tag">dashboard</span><span class="hljs-selector-class">.csr</span> <span class="hljs-selector-tag">-signkey</span> <span class="hljs-selector-tag">dashboard</span><span class="hljs-selector-class">.key</span> <span class="hljs-selector-tag">-out</span> <span class="hljs-selector-tag">dashboard</span><span class="hljs-selector-class">.crt</span>
openssl x509 -days 3650 -req -in dashboard.csr -signkey dashboard.key -out dashboard.crt
这里指定了过期时间3650天，默认365天
4.2 部署Dashboard插件
4.2.1 创建部署kubernetes-dashboard的yaml文件
（文件下载地址：链接：https://pan.baidu.com/s/1L1epcWiEI7v2C4bHo2nx3Q 提取码：1fsh）
根据官方文件做了微调:
- 把cert注释掉，使用待会自己创建的cert,因为默认的证书有问题；
- 把dashboard访问方式改为NodePort,端口是31234，访问时用pod所在主机的ip加端口号即可访问;
- imagePullPolicy改为IfNotPresent,当本地找不到镜像时才从网上拉取;
注意查看镜像路径是否有效，如果无效，自行百度查找镜像源，或者到别的地方把镜像下载到本地，然后把tag改成和yaml文件中的image一致- arm镜像源修改kubernetesui/metrics-scraper-arm64:v1.0.6和kubernetesui/dashboard-arm64:v2.0.5
4.2.2 部署kubernetes-dashboard
<span class="hljs-attribute">kubectl</span> apply -f /opt/kubernetes-dashboard.yaml<span class="hljs-attribute">kubectl</span> apply -f /opt/kubernetes-dashboard.yaml
kubectl apply -f /opt/kubernetes-dashboard.yaml
4.2.3 部署完成后还是不能访问，因为yaml文件中注释掉了kubernetes-dashboard-certs，相关的pod没跑起来，所以此时应创建certs
kubectl create secret generic kubernetes-dashboard-certs --<span class="hljs-keyword">from</span>-file=<span class="hljs-regexp">/opt/</span>dashboard.key --<span class="hljs-keyword">from</span>-file=<span class="hljs-regexp">/opt/</span>dashboard.crt -n kubernetes-dashboardkubectl create secret generic kubernetes-dashboard-certs --<span class="hljs-keyword">from</span>-file=<span class="hljs-regexp">/opt/</span>dashboard.key --<span class="hljs-keyword">from</span>-file=<span class="hljs-regexp">/opt/</span>dashboard.crt -n kubernetes-dashboard
kubectl create secret generic kubernetes-dashboard-certs --from-file=/opt/dashboard.key --from-file=/opt/dashboard.crt -n kubernetes-dashboard
4.2.4 如果失败检查方式
一般经过以上步骤就可以访问dashboard，可以跳过这一步了，但如果此时仍不能访问，pod不是处于"running"状态，可以删除kubenetes-dashboard相关的pod，让kubelet自动生成一个新的可运行的pod
查看kubernetes-dashboard的pod名
kubectl <span class="hljs-keyword">get</span> pods -n kubernetes-dashboardkubectl <span class="hljs-keyword">get</span> pods -n kubernetes-dashboard
kubectl get pods -n kubernetes-dashboard
删除该pod:
kubectl <span class="hljs-keyword">delete</span> pod -n kubernetes-dashboard <pod名>kubectl <span class="hljs-keyword">delete</span> pod -n kubernetes-dashboard <pod名>
kubectl delete pod -n kubernetes-dashboard <pod名>

4.3 创建访问用户,用于访问dashboard的Service Account
kubectl <span class="hljs-keyword">create</span> serviceaccount <span class="hljs-keyword">admin</span>-<span class="hljs-keyword">user</span> -n kubernetes-dashboardkubectl <span class="hljs-keyword">create</span> serviceaccount <span class="hljs-keyword">admin</span>-<span class="hljs-keyword">user</span> -n kubernetes-dashboard
kubectl create serviceaccount admin-user -n kubernetes-dashboard
4.4 为用户绑定角色，创建ClusterRoleBinding
kubectl <span class="hljs-keyword">create</span> clusterrolebinding <span class="hljs-keyword">admin</span>-<span class="hljs-keyword">user</span> <span class="hljs-comment">--clusterrole=cluster-admin --serviceaccount=kubernetes-dashboard:admin-user</span>kubectl <span class="hljs-keyword">create</span> clusterrolebinding <span class="hljs-keyword">admin</span>-<span class="hljs-keyword">user</span> <span class="hljs-comment">--clusterrole=cluster-admin --serviceaccount=kubernetes-dashboard:admin-user</span>
kubectl create clusterrolebinding admin-user --clusterrole=cluster-admin --serviceaccount=kubernetes-dashboard:admin-user
4.5 获取登录密钥
kubectl -n kubernetes-dashboard <span class="hljs-keyword">describe</span> secret $(kubectl -n kubernetes-dashboard <span class="hljs-keyword">get</span> secret | grep <span class="hljs-keyword">admin</span>-<span class="hljs-keyword">user</span> | awk <span class="hljs-string">'{print $1}'</span>)kubectl -n kubernetes-dashboard <span class="hljs-keyword">describe</span> secret $(kubectl -n kubernetes-dashboard <span class="hljs-keyword">get</span> secret | grep <span class="hljs-keyword">admin</span>-<span class="hljs-keyword">user</span> | awk <span class="hljs-string">'{print $1}'</span>)kubectl -n kubernetes-dashboard describe secret $(kubectl -n kubernetes-dashboard get secret | grep admin-user | awk '{print $1}')

五、卸载K8S组件
注意：
下列步骤仅仅指导用户如何手动卸载K8s组件，请勿在正常的部署过程中执行。
清空K8s集群设置。
在卸载K8s组件前，先执行kubeadm reset命令，清空K8s集群设置。
卸载管理组件。
<span class="hljs-attribute">yum</span> erase -y kubelet kubectl kubeadm kubernetes-cni<span class="hljs-attribute">yum</span> erase -y kubelet kubectl kubeadm kubernetes-cni
yum erase -y kubelet kubectl kubeadm kubernetes-cni
删除基础组件镜像。
基础组件通过Docker镜像部署，因此只需要强制删除对应镜像即可卸载。
