centos7搭建docker本地regsitry

1、環境準備
ip
docker倉庫機 10.5.0.50
docker客戶機 10.5.0.51

關閉防火牆
systemctl stop firewalld.service
systemctl disable firewalld.service

關閉本地selinux防火牆
sed -i 's/SELINUX=.*/SELINUX=disabled/' /etc/sysconfig/selinux
getenforce 0

2、搭建

1.搭建倉庫 registry
docker pull regsity

2.基於私有倉庫鏡像運行容器

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

3.訪問私有倉庫

網上都用這個curl 127.0.0.1:5000/v1/search,可是報404 page not found，後查證是v1版本的api查看方式，咱們如今的版本是v2，因此用以下方法查看：

curl -X GET http://10.5.0.50:5000/v2/_catalog
{"repositories":[]} #私有倉庫爲空，沒有提交新鏡像到倉庫中

4.爲基礎鏡像打個標籤

根據 images id 創建 tag

docker tag a374fd62f97f 10.5.0.50:5000/centos

5.改Docker配置文件指定私有倉庫url

vim /etc/sysconfig/docker
OPTIONS='--selinux-enabled --insecure-registry 10.5.0.50:5000'
systemctl restart docker

6. 提交鏡像到本地私有倉庫中

docker push 10.5.0.50:5000/centos

7.查看私有倉庫是否存在對應的鏡像

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"]}

3、在docker客戶機驗證
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.從私有倉庫中下載已有的鏡像

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 ID CREATED SIZE

運行

docker run -itd 10.5.0.50:5000/centos

自此，docker本地倉庫搭建完成。。。
