2、配置本地yum源
2.1、安装http服务，将yum文件夹拷贝到,并设置权限
[root@k8smaster01 ~]# cp -r /home/zhaiky/yum /var/www/html/
[root@k8smaster01 html]# chmod -R 777 yum/
2.2、配置yum.repo文件
[root@k8snode01 etc]# more yum.repo 
[yum]
name=base
baseurl=http://192.168.23.134/yum
gpgcheck=0
[root@k8smaster01 yum.repos.d]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: base elrepo extras updates yum
[root@k8smaster01 yum.repos.d]# 

3、docker私有仓库的搭建，安装docker
[root@k8smaster01 ~]# yum install docker -y
Loaded plugins: fastestmirror

4、上传registry_v2.tar和nginx.tar导入镜像

镜像包：

提取码：jpfe 
[root@k8smaster01 zhaiky]# docker load -i registry_v2.tar
Loaded image: docker.io/registry:latest
[root@k8smaster01 zhaiky]# docker load -i nginx.tar 
Loaded image: 192.168.23.134:5000/nginx:latest
[root@k8smaster01 zhaiky]# docker images
REPOSITORY                  TAG                 IMAGE ID            CREATED             SIZE
192.168.23.134:5000/nginx   latest              c7460dfcab50        5 days ago          126 MB
docker.io/registry          latest              f32a97de94e1        10 months ago       25.8 MB
[root@k8smaster01 zhaiky]# 

5、启动仓库
[root@k8smaster01 registry]# docker run -d -p 5000:5000 --restart=always --name private-docker-registry --privileged=true -v /data/registry:/var/lib/registry registry
76d008081e427438a2efed0b1f579711025b8c27265472296f3b89d1037d0c60
[root@k8smaster01 registry]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
76d008081e42        registry            "/entrypoint.sh /e..."   10 seconds ago      Up 9 seconds        0.0.0.0:5000->5000/tcp   private-docker-registry
[root@k8smaster01 registry]#
说明：-d表示容器在后台运行。-p 5000:5000表示将容器的5000端口映射到虚拟机的5000端口。–restart=always表示容器随着docker启动而启动，同时若容器异常终止，会自动启动；实测表明，使用docker stop命令停止容器后，
此参数不会让容器自动重启。–name private-docker-registry设置容器名。–privileged=true使容器真正具有容器内的root权限。-v /data/registry:/var/lib/registry将容器中的/var/lib/registry目录映射
到虚拟机的/data/registry；/var/lib/registry是私有仓库容器存放镜像的目录。

6、nginx推送到私有仓库
[root@k8smaster01 registry]# docker push 192.168.23.134:5000/nginx:latest
The push refers to a repository [192.168.23.134:5000/nginx]
Get https://192.168.23.134:5000/v1/_ping: http: server gave HTTP response to HTTPS client
