-
启动私有仓库容器
[root@server-a ~]# docker run -id --name=registry -p 5000:5000 registry
-
打开浏览器,输入地址http://私有仓库服务器 ip:5000/v2/_catalog
-
修改daemon json 追加信息
[root@server-a ~]# vim /etc/docker/daemon.json [root@server-a ~]# cat /etc/docker/daemon.json { "registry-mirrors": ["https://m03eesz2.mirror.aliyuncs.com"], "insecure-registries":["192.168.10.128:5000"] }
-

查看镜像
[root@server-a ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE app latest d8cb1b6dcd58 30 hours ago 488MB nginx latest 605c77e624dd 16 months ago 141MB openjdk latest 5f94f53bbced 16 months ago 471MB tomcat latest fb5657adc892 16 months ago 680MB registry latest b8604a3fe854 18 months ago 26.2MB centos 7 eeb6ee3f44bd 20 months ago 204MB
-
将centos7传入仓库,先打上标记
[root@server-a ~]# docker tag centos:7 192.168.10.128:5000/centos:7 [root@server-a ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE app latest d8cb1b6dcd58 30 hours ago 488MB nginx latest 605c77e624dd 16 months ago 141MB openjdk latest 5f94f53bbced 16 months ago 471MB tomcat latest fb5657adc892 16 months ago 680MB registry latest b8604a3fe854 18 months ago 26.2MB 192.168.10.128:5000/centos 7 eeb6ee3f44bd 20 months ago 204MB centos 7 eeb6ee3f44bd 20 months ago 204MB

错误
[root@server-a ~]# docker push 192.168.10.128:5000/centos Using default tag: latest The push refers to repository [192.168.10.128:5000/centos] tag does not exist: 192.168.10.128:5000/centos:latest
这段话提示没有此标签,检查了下,这里我的centos后面没有加上版本号7 ,如果你是latest就不用加
-
解决
[root@server-a ~]# docker push 192.168.10.128:5000/centos:7
The push refers to repository [192.168.10.128:5000/centos]

- 访问http://私有仓库服务器 ip5000/v2/_catalog
