centos7搭建docker本地regsitry
一、环境准备ip
docker仓库机 10.5.0.50
docker客户机 10.5.0.51
关闭防火墙
systemctl stop firewalld.service
systemctl 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 http://10.5.0.50:5000/v2/_catalog
{"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> 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
[*]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 http://10.5.0.50:5000/v2/_catalog
{"repositories":["centos","nginx"]}
curl -X GET http://10.5.0.50:5000/v2/centos/tags/list
{"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: latest
Trying to pull repository 10.5.0.50:5000/centos ...
latest: Pulling from 10.5.0.50:5000/centos
Digest: sha256:fd9058a6149809b2f4725bb4461294ceebb59e587435f3509c2c8dcc9ee1d5b4
Status: Downloaded newer image for 10.5.0.50:5000/centos:latest
查看
docker images
REPOSITORY TAG IMAGE> 10.5.0.50:5000/centos latest a374fd62f97f 11 weeks ago 194.5 MB
docker.io/centos 6.8 a374fd62f97f 11 weeks ago 194.5 MB
运行
docker run -itd 10.5.0.50:5000/centos
2da2c1e9e70146b71a68f829e89756664f1e2a67abf369baac524c65deb25
docker ps
CONTAINER> 2da2c1e9e 10.5.0.50:5000/centos "/bin/bash" About a minute ago Up About a minute thirsty_elion
自此，docker本地仓库搭建完成。。。
