一、环境准备

ipdocker仓库机 10.5.0.50docker客户机 10.5.0.51

关闭防火墙

systemctl stop firewalld.servicesystemctl disable firewalld.service

关闭本地selinux防火墙

sed -i 's/SELINUX=.*/SELINUX=disabled/' /etc/sysconfig/selinux getenforce 0

二、搭建

1.搭建仓库 registry

docker pull regsity

2.基于私有仓库镜像运行容器

docker run -d -p 5000:5000 --privileged=true --restart=always -v /opt/registry:/tmp/registry registry

3.访问私有仓库

网上都用这个curl 127.0.0.1:5000/v1/search,但是报404 page not found，后查证是v1版本的api查看方式，我们现在的版本是v2，所以用如下方法查看：

curl -X GET

{"repositories":[]} #私有仓库为空，没有提交新镜像到仓库中

4.为基础镜像打个标签

根据 images id 建立 tag

docker tag a374fd62f97f 10.5.0.50:5000/centos

5.改Docker配置文件指定私有仓库url

vim /etc/sysconfig/docker

OPTIONS='--selinux-enabled --insecure-registry 10.5.0.50:5000'systemctl restart docker

6. 提交镜像到本地私有仓库中

docker push 10.5.0.50:5000/centos

7.查看私有仓库是否存在对应的镜像

root@localhost ~

curl -X GET {"repositories":["centos","nginx"]}curl -X GET {"name":"centos","tags":["latest"]}

三、在docker客户机验证

1.修改Docker配置文件

vim /etc/sysconfig/docker

OPTIONS='--selinux-enabled --insecure-registry 10.5.0.50:5000'systemctl restart docker

2.从私有仓库中下载已有的镜像

docker pull 10.5.0.50:5000/centos

Using default tag: latestTrying to pull repository 10.5.0.50:5000/centos ... latest: Pulling from 10.5.0.50:5000/centosDigest: sha256:fd9058a6149809b2f4725bb4461294ceebb59e587435f3509c2c8dcc9ee1d5b4Status: Downloaded newer image for 10.5.0.50:5000/centos:latest

查看

docker images

运行

docker run -itd 10.5.0.50:5000/centos

自此，docker本地仓库搭建完成。。。
