运行私有库registry

命令：

docker run -d -p 5000:5000 -v /zzyyuse/myregistry/:/tmp/registry --privileged=true registry

[root@192 ~]# docker run -d -p 5000:5000 -v /zzyyuse/myregistry/:/tmp/registry --privileged=true registry

生成自己的镜像

用docker commit命令生成新的镜像。

[root@192 ~]# docker ps

curl验证私服库上有什么镜像

命令：

curl -XGET http://192.168.12.130:5000/v2/_catalog ip为本地ip

[root@192 ~]# curl -XGET http://192.168.12.130:5000/v2/_catalog
{"repositories":[]}

将新镜像修改符合私服规范的TAG

命令：

docker tag 镜像:TAG Host:Port/Repository:Tag

[root@192 ~]# docker tag kd/myubuntu:1.2 192.168.12.130:5000/kdubuntu:1.2
[root@192 ~]# docker images

修改配置文件使支持http

文件：/etc/docker/daemon.json

[root@192 ~]# cat /etc/docker/daemon.json 
{

"registry-mirrors": ["https://pylcjgsv.mirror.aliyuncs.com"],
"dns" : [
    "8.8.8.8"
  ],
"insecure-registries":["192.168.12.130:5000"]

}

修改完成后，如果不生效的话，建议重启docker。

重启后，重新运行私服仓库。

push推送到私服库,并验证

命令：

docker push 192.168.12.130:5000/kdubuntu:1.2

[root@192 ~]# docker images
