1.docker 实例
| ip | hostname |
|---|---|
| 192.168.1.180 | basenode |
| 192.168.1.151 | bigdata01.com |
在192.168.1.151 服务网器上拉去私服运行私服
docker 私服官网 https://hub.docker.com/_/registry
2. 拉去私服 ： docker pull registry
3. 运行容器 ：
docker run -itd -p 5000:5000 --name registry --restart=always registry:2.7.1
[root@bigdata01 ~]# docker run -itd -p 5000:5000 --name registry --restart=always registry:2.7.1

[root@bigdata01 ~]#
４.（192.168.1.180） 将另外一台机器的容器推送到私服
4.1 推送镜像 docker tag nginx:latest 192.168.1.151:5000/nginx:v1
[root@basenode ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
tomcat latest b0e0b0a92cf9 2 weeks ago 680MB

[root@basenode ~]# docker tag nginx:latest 192.168.1.151:5000/nginx:v1
[root@basenode ~]#
5. 在另外一台机器中查看镜像 （192.168.1.151）
多了刚才的nginx 镜像
[root@bigdata01 ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
mongo latest fefd78e9381a 2 weeks ago 699MB
nginx latest 87a94228f133 3 weeks ago 133MB
registry 2.7.1 b2cb11db9d3d 2 months ago 26.2MB
registry.cn-hangzhou.aliyuncs.com/anoy/yapi latest 76d11bb7c386 22 months ago 170MB
[root@bigdata01 ~]#
6. 在主节点添加内容 将https 修改为http 的方式进行访问（192.168.1.180 中修改）
编辑配置文件
vi /etc/docker/daemon.json
增加仓库配置信息
{ "insecure-registries":["192.168.1.151:5000"] }
重启docker
systemctl daemon-reload
systemctl restart docker
查看docker信息确认仓库是否添加
docker info
如下
[root@basenode ~]# vi /etc/docker/daemon.json
{
"registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"],
"insecure-registries":["192.168.1.151:5000"]
}
6.1 重启docker 服务 （192.168.1.180 中修改）
[root@basenode ~]# docker tag nginx:latest 192.168.1.151:5000/nginx:v1
[root@basenode ~]# vi /etc/docker/daemon.json
[root@basenode ~]# systemctl daemon-reload
[root@basenode ~]# systemctl restart docker
