1、…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Kubernetesk8s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.cgroupdriversystemd],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

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-address192.168.254.135 \--image-repository registry.aliyuncs.com/google_containers \--kubernetes-version v1.18.0 \--service-cidr10.96.0.0/12 \--pod-network-cidr10.244.0.0/16 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 root192.168.254.135:/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 --imageregistry.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 --port8088 --target-port8088 --typeNodePort
#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-dhvtc13、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
