###設定私有倉庫 registry
一、建立docker
1.設定防火牆

iptables -I INPUT 1 -p tcp --dport 5000 -j ACCEPT

 2. 新增軟體源資訊

sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

3. 更新並安裝 Docker-CE

sudo yum makecache fast
sudo yum -y install docker-ce
 

4. 開啟Docker服務

systemctl start docker && systemctl enable docker 

##docker info 檢視資訊
 docker info
5. ###新增自定義倉庫加速器

cat<<END>/etc/docker/daemon.json
{
"registry-mirrors":["https://vaflkxbk.mirror.aliyuncs.com"]
}
END

6. 重啟服務                                                                                                                                                   

systemctl daemon-reload && systemctl restart docker && docker info ##確定 自定義倉庫新增

二、建立倉庫
##7. 建立私有創庫倉庫   

 docker run -d -p 5000:5000 -v /data/registry:/var/lib/registry --name registry --restart=always registry

##8.測試

docker pull ningx
docker tag nginx 192.168.97.208:5000/nginx   
docker push 192.168.97.208:5000/nginx
 

###報錯如下

unable to ping registry endpoint https://192.168.97.208:5000/v0/
v2 ping attempt failed with error: Get https://192.168.97.208:5000/v2/: http: server gave HTTP response to HTTPS client

###在daemon.json 中新增如下

vi /etc/docker/daemon.json
{
"registry-mirrors":["https://vaflkxbk.mirror.aliyuncs.com"],
"insecure-registries": ["192.168.97.208:5000"]
} 

###再次測試

docker push 192.168.97.208:5000/nginx
The push refers to repository [192.168.97.208:5000/nginx]
3ff93588120e: Pushed
