编辑yml文件

[root@localhost harbor]# vim harbor.yml

登录harbor的web端

默认账号：admin 默认密码：Harbor12345

创建harbor项目仓库与用户

创建用户

项目添加成员

k8s使用harbor仓库

在node1节点上

[root@k8s-node1 ~]# vim /etc/docker/daemon.json 
添加不安全仓库

node1与node2都需要添加！！！

重启docker

[root@k8s-node1 ~]# systemctl restart docker

开始推送镜像

登录harbor

修改要推送镜像名字

[root@k8s-node1 ~]# docker images
REPOSITORY                                           TAG        IMAGE ID       CREATED         SIZE

[root@k8s-node1 ~]# docker tag  192.168.231.192/nginx:latest 192.168.231.130/nginx/test:v1.0

开始推送

[root@k8s-node1 ~]# docker push 192.168.231.130/nginx/test:v1.0

集群中如何使用镜像

[root@k8s-master ~]# vim nginx.yml 

apiVersion: v1
kind: Pod
metadata:
  name: test 
spec:
  containers:
  - name: nginx-test 
    image: 192.168.231.130/nginx/test:v1.0

创建pod

[root@k8s-master ~]# kubectl apply -f nginx.yml 
pod/test created
[root@k8s-master ~]# kubectl get pod
NAME                               READY   STATUS    RESTARTS        AGE
test                               1/1     Running   0               4s
