## 一、CoreDNS级联本地DNS服务器(k8s集群master节点配置) ##

# kubectl edit configmap coredns -n kube-system
    
    apiVersion: v1
    data:
      Corefile: |
        .:53 {
        
            errors
            health {
        
               lameduck 5s
            }
            ready
            kubernetes cluster.local in-addr.arpa ip6.arpa {
        
               pods insecure
               fallthrough in-addr.arpa ip6.arpa
               ttl 30
            }
            prometheus :9153
            forward . /etc/resolv.conf {
         修改这里为本地DNS IP地址
               max_concurrent 1000
            }
            cache 30
            loop
            reload
            loadbalance
        }
        
        
     修改为：
     apiVersion: v1
    data:
      Corefile: |
        .:53 {
        
            errors
            health {
        
               lameduck 5s
            }
            ready
            kubernetes cluster.local in-addr.arpa ip6.arpa {
        
               pods insecure
               fallthrough in-addr.arpa ip6.arpa
               ttl 30
            }
            prometheus :9153
            forward . 192.168.10.145 {
         重点注意看IP地址，修改为本地DNS IP地址
               max_concurrent 1000
            }
            cache 30
            loop
            reload
            loadbalance
        }

# dig -t a harbor.msb.com @10.96.0.10

## 二、添加本地非安全容器镜像仓库至Docker配置(k8s集群全部节点配置) ##

# cat /etc/docker/daemon.json
    {
        
            "exec-opts": ["native.cgroupdriver=systemd"]，
            "insecure-registries": ["http://harbor.msb.com"]
    }
    
    修改为：
    
    # cat /etc/docker/daemon.json
    {
        
            "exec-opts": ["native.cgroupdriver=systemd"]
    }

# cat /usr/lib/systemd/system/docker.service
    [Unit]
    Description=Docker Application Container Engine
    Documentation=https://docs.docker.com
    After=network-online.target docker.socket firewalld.service containerd.service
    Wants=network-online.target
    Requires=docker.socket containerd.service
    
    [Service]
    Environment="DOCKER_OPTS=--insecure-registry=http://harbor.msb.com" 在此处添加
    Type=notify
    # the default is not to use systemd for cgroups because the delegate issues still
    # exists and systemd currently does not support the cgroup feature set required
    # for containers run by docker
    ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --insecure-registry=http://harbor.msb.com
    ExecReload=/bin/kill -s HUP $MAINPID
    TimeoutSec=0
    RestartSec=2
    Restart=always

# systemctl daemon-reload 
    
    # systemctl restart docker

## 三、KubeSphere仓库配置密钥 ##

> 在使用本地容器镜像仓库Harbor之前，需要创建密钥文件

## 四、创建应用进行测试及访问（在harbor节点操作） ##

### 4.1 容器镜像准备 ###

# docker pull nginx:latest

# docker tag nginx:latest harbor.msb.com/library/nginx:v1

# docker push harbor.msb.com/library/nginx:v1
