之前看了很多文章，都是部署后一直报错，百度解决后下次又忘了，这次决定把从头到尾的过程记录下来方便下次再看，部署参考文章尚硅谷Kubernetes（k8s）视频学习笔记_尚硅谷k8s笔记_溯光旅者的博客-CSDN博客

1、先去下载vmware虚拟机安装，我安装的是这个版本VMware Workstation 16 Player

2、去阿里云网站下载centos7镜像

centos-7-isos-x86_64安装包下载_开源镜像站-阿里云

3、新增两台虚拟机用来部署,创建步骤都是一样的

wxsmaster 4G 4核 30G

wxsnode1 4G 4核 30G

这里点完成之后一直等待，直到系统创建成功

4、ifconfig命令查看ip后开始按顺序执行下面步骤，都整理好了

#设置主机名分别在wxsmaster执行和wxsnode1执行，设置完后用hostname可以查看名称
hostnamectl set-hostname wxsmaster
hostnamectl set-hostname wxsnode1#关闭防火墙，用systemctl status firewalld查看是否关闭
systemctl stop firewalld
systemctl disable firewalld#关闭 selinux
sed -i 's/enforcing/disabled/' /etc/selinux/config # 永久
setenforce 0 # 临时#关闭 swap，关闭后用free -m命令查看是否关闭
swapoff -a # 临时
sed -ri 's/.*swap.*/#&/' /etc/fstab    # 永久#时间同步，同步后可用date查看
yum install ntpdate -y
ntpdate time.windows.com#在 master 添加 hosts
cat >> /etc/hosts << EOF
192.168.254.135 wxsmaster
192.168.254.136 wxsnode1
EOF#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 # 生效#安装docker
wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
yum -y install docker-ce-18.06.1.ce-3.el7
systemctl enable docker && systemctl start docker
docker --version#配置docker的驱动和阿里云加速器
cat > /etc/docker/daemon.json << EOF
{"exec-opts": ["native.cgroupdriver=systemd"],"registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"]
}
EOF#重新加载配置参数，重新启动docker服务，启动后用docker info | grep Cgrou 查看docker驱动是否为systemd
systemctl daemon-reload
systemctl restart docker#添加阿里云 YUM 软件源
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 kubeadm， kubelet 和 kubectl
yum install -y kubelet-1.18.0 kubeadm-1.18.0 kubectl-1.18.0
systemctl enable kubelet

5、初始化，只有wxsmaster执行这个命令，下面的apiserver-advertise-address值要改成master节点的ip

kubeadm init \--apiserver-advertise-address=192.168.254.135 \--image-repository registry.aliyuncs.com/google_containers \--kubernetes-version v1.18.0 \--service-cidr=10.96.0.0/12 \--pod-network-cidr=10.244.0.0/16

6、初始化完成后，拷贝出图片里面的命令，在wxsnode1节点执行

kubeadm join 192.168.254.135:6443 --token 23zsua.gsa9vwevq3ee3kdn \--discovery-token-ca-cert-hash sha256:eb3eba970a429129748ad936d859ac7694e7ea6ed5dc7c8cf5220c8a4d3061ed

7、kubectl get nodes查看节点发现报错了，两台机器加入环境变量解决

#两台机器都加入环境变量
vim /etc/profile
export KUBECONFIG=/etc/kubernetes/admin.conf
source /etc/profile#wxsnode1节点加入后还是报错，缺少文件，需要从wxsmaster节点拷贝过来
scp root@192.168.254.135:/etc/kubernetes/admin.conf /etc/kubernetes

8、kubectl get nodes查看节点状态NotReady，用journalctl -xefu kubelet查看运行状态，发现报错了，需要安装Pod 网络插件（ CNI）（只有wxsmaster主机安装）

本地新增一个文件kube-flannel.yaml，贴入一下内容，或者去这个网址下载https://github.com/flannel-io/flannel/blob/master/Documentation/kube-flannel.yml

用xftp将这个文件传入master某个目录，我是这个

安装命令：kubectl apply -f kube-flannel.yaml，安装完后状态变ready了

9、本地打包springboot的jar包，本地最好java -jar启动一下看是否能成功，不然后面报错找问题找半天(经验之谈)

10、去阿里云服务器新增命名空间和镜像仓库

11、创建完后上传jar包到虚拟机，用上图第3步骤将docker生成的镜像上传到阿里云服务器

#创建Dockerfile，并上传jar包到里面配置目录
vim Dockerfile
#输入下面内容
FROM openjdk:8-jdk-alpine
ADD wxstest.jar /home/wxs/wxstest/wxstest.jar
ENTRYPOINT ["java", "-jar", "/home/wxs/wxstest/wxstest.jar"]#制作镜像
docker build -t wxstest:1.0.0 .#查看镜像
docker images#重命名镜像
docker tag 30a9f619627f registry.cn-hangzhou.aliyuncs.com/wxsnamespace/wxstest:1.0.0#推送到阿里云仓库
docker push registry.cn-hangzhou.aliyuncs.com/wxsnamespace/wxstest:1.0.0#拉取镜像
docker pull registry.cn-hangzhou.aliyuncs.com/wxsnamespace/wxstest:1.0.0#先用docker部署下看看是否成功，不然后面报错要重搞好久
docker run -d -p 8088:8088 registry.cn-hangzhou.aliyuncs.com/wxsnamespace/wxstest:1.0.0 -t

12、创建应用，我的目录是/home/wxs/wxstest

#创建应用
kubectl create deployment  wxstest --image=registry.cn-hangzhou.aliyuncs.com/wxsnamespace/wxstest:1.0.0
#删除命令kubectl delete deployment wxstest#把上面打印出来的内容保存到 wxstest.yaml中，并执行下面命令,执行完后用这个命令看是否成功kubectl get deployments
kubectl expose deployment wxstest --port=8088 --target-port=8088 --type=NodePort
#删除命令kubectl delete svc wxstest#查看应用
kubectl get services#本机访问看是否能正常返回页面
curl http://10.100.143.1:8088/mylogin.html#查看容器名称
kubectl get pods -o wide#查看容器日志
kubectl logs -f wxstest-64686ddd65-dhvtc

13、外网请求虚拟机地址看看

http://192.168.254.135:32057/mylogin.html

http://192.168.254.136:32057/mylogin.html

14、重启了虚拟机后发现两台机器ip地址变了，需要改成静态ip，配置从本机拿

#进入配置文件
vi /etc/sysconfig/network-scripts/ifcfg-ens33 #改成如下配置，有的不需要改
TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="static"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="ens33"
UUID="285c38d7-6392-478d-ba1d-131066ba5e4d"
DEVICE="ens33"
ONBOOT="yes"IPADDR="192.168.254.135"
NETMASK="255.255.255.0"
GATEWAY="192.168.254.2"
DNS1="8.8.8.8"#重启
reboot

15、完事了~~
