虚拟机部署单机版kubernetes,minikube,docker

# 目前公司用的是阿里云的容器服务所以本地搭建个单机版方便测试使用
# VMware® Workstation 12 Pro 版本
# 虚拟机环境配置：配置 2核 4G 网络桥接
# 系统镜像： CentOS-7-x86_64-Minimal-1810.iso 最好从阿里云镜像系统下载可以省去yum仓库的配置
# 网站地址： https://developer.aliyun.com/mirror/
# 下载 CentOS-7-x86_64-Everything-1908.iso 这个更省事链接如下
https://mirrors.aliyun.com/centos/7.7.1908/isos/x86_64/CentOS-7-x86_64-Everything-1908.iso
# docker 文档
https://docs.docker.com/engine/install/centos/
# 执行 su 切换到 root 用户
# 关掉防火墙
# systemctl stop firewalld
# systemctl disable firewalld
# 清理老版本
# sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine

# cd /etc/yum.repos.d
# xftp 上传附件 *.repo 文件到 /etc/yum.repos.d
# yum update
# 阿里云镜像加速地址,自行阿里云申请
# vi /etc/docker/daemon.json

{
"registry-mirrors": ["https://xxxxxxx.mirror.aliyuncs.com"]
}

# 安装 docker
# sudo yum install docker-ce docker-ce-cli containerd.io
#会从阿里云下载镜像

# 启动docker 服务
# systemctl start docker
# systemctl enable docker
# 查看版本
# docker version

# 安装 minikube , kubectl 自行下载或直接使用附件
# 文档 https://kubernetes.io/zh/docs/tasks/tools/install-minikube/
# cd /home/admin/
# 自己下载
# curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube
# https://kubernetes.io/zh/docs/tasks/tools/install-kubectl/
# curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.18.0/bin/linux/amd64/kubectl && chmod +x kubectl

# 使用附件 minikube和kubectl软件上传到 /home/admin
# 执行
# sudo mkdir -p /usr/local/bin/
# sudo install minikube /usr/local/bin/
# sudo install kubectl /usr/local/bin/
# 查看版本
minikube version
minikube version: v1.9.0

# 确保 root用户
# su root
# 执行单机版 driver=none 配置 image-repository=registry.cn-hangzhou.aliyuncs.com/google_containers 否则镜像下载极慢
# minikube start --image-repository=registry.cn-hangzhou.aliyuncs.com/google_containers --driver=none
# 问题缺少conntrack ： X Sorry, Kubernetes v1.18.0 requires conntrack to be installed in root's path
# yum install conntrack
# 再次运行
# minikube start --image-repository=registry.cn-hangzhou.aliyuncs.com/google_containers --driver=none
# 首次较慢等待下载完成缺保配置有 4g内存
# 启动成功显示如下
# Done! kubectl is now configured to use "minikube"

# 查看
# kubectl get pod --all-namespaces

# 输入如下来解决网络问题的报错
# echo '1' > /proc/sys/net/bridge/bridge-nf-call-iptables

#服务器上执行，启动管理界面，服务器本地可以浏览器查看面板 Minimal版本os没有桌面
minikube dashboard

#服务器上执行代理8001 到面板服务
kubectl proxy --address='0.0.0.0' --accept-hosts='^*$'
# 并开放端口8001或关闭防火墙 ping ipxxxxx 8001 通不通
# 客户端浏览器访问
# http://ipxxxxx:8001/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/#/overview?namespace=default
# 查看版本
# kubectl version

#处理 ingress
#先下载镜像下载有点慢
docker pull quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.26.1
minikube addons enable ingress

# 上传附件中 mq的Dockerfile /root
# docker build -t rabbitmq:2020 .
# 查看镜像 rabbitmq:2020
# docker images
# 上传附件中 mq的rabbitmq-deployment.yaml /root
# 部署 rabbitmq
# kubectl apply -f rabbitmq-deployment.yaml
# 查看
kubectl get pod
#port-forward 端口转发的前置依赖软件安装
# sudo yum install -y socat

#查看服务器端配置
# kubectl config view
