# 单节点运用kubesphere3.0实现容器管理 #

# kubesphere3.0优点 #

颜值高
    有完善的权限发布控制功能
    安装简单
    功能较为完善
    支持可视化流水线编辑

# 基础环境准备 #

# 关闭防火墙
    systemctl stop firewalld.service
    systemctl disable firewalld
    firewall-cmd --reload
    
    # 关闭selinux
    setenforce 0  # 临时
    sed -i 's/enforcing/disabled/' /etc/selinux/config  # 永久
    
    #设置hostname
    hostnamectl set-hostname k8s-master01
    
    /etc/hosts添加一行内容：
    47.115.183.185  k8s-master01
    
    
    
    # 关闭swap
    swapoff -a  # 临时
    sed -ri 's/.*swap.*/#&/' /etc/fstab    # 永久
    
    
    # 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
    
    -----------------------------------同步机器时间-------------------------------
    
    #安装chrony
    yum -y install chrony
    
    #修改同步服务器地址为阿里云
    sed -i.bak '3,6d' /etc/chrony.conf && sed -i '3cserver ntp1.aliyun.com iburst' \
    /etc/chrony.conf
    
    # 启动chronyd及加入开机自启
    systemctl start chronyd && systemctl enable chronyd
    
    #查看同步结果
    chronyc sources

# harbor私有仓库的安装 #

# 安装kubesphere3.0最小化安装 #

#提前安装一些工具包
    yum install -y socat
    yum install -y nfs-utils
    yum install -y conntrack-tools
    
    #下载KubeKey
    wget -c https://kubesphere.io/download/kubekey-v1.0.0-linux-amd64.tar.gz -O - | tar -xz
    # 授权KubeKey
    chmod +x kk
    # 安装kubesphere3.0，这一步过程比较慢，大部分时间在拉取几个G的镜像
    ./kk create cluster --with-kubernetes v1.17.9 --with-kubesphere v3.0.0

# 安装KubeSphere App Store插件 #

注意：一定要完成kubesphere3.0最小化安装安装之后，才能进行各种插件的安装。

安装KubeSphere App Store插件个人感觉没有什么用，可以不安装。不安装的可以跳过这一节

## 下载cluster-configuration.yaml文件 ##

https://raw.githubusercontent.com/kubesphere/ks-installer/v3.0.0/deploy/cluster-configuration.yaml

## 修改cluster-configuration.yaml配置 ##

openpitrix:
        enabled: true # Change "false" to "true"

## 启动插件相关的pod ##

kubectl apply -f cluster-configuration.yaml

等待一段时间，看网速了

# 安装KubeSphere DevOps System插件 #

类似KubeSphere App Store插件的安装，我们主要修改上一步的cluster-configuration.yaml文件，然后重新kubectl apply -f cluster-configuration.yaml即可。

## 修改cluster-configuration.yaml配置 ##

devops:
        enabled: true # Change "false" to "true"
