docker简单私有仓库的搭建

示例：【搭建简单的Registry仓库】

下载 Registry 镜像

root@docker \~\]# docker pull registry ![](https://i-blog.csdnimg.cn/direct/194209001f33416096793cf2df1ea099.png) #可以查看开放的端口，需要把端口暴露出来 \[root@docker \~\]# docker history registry:latest ![](https://i-blog.csdnimg.cn/direct/07c5d3cdd00b44a7a68b9dbbf9dc9a2f.png) \[root@docker \~\]# docker run -d -p 5000:5000 --restart=always registry 9f389c98fbd2163fb6487a5bfd2358751eb4ecb07eb47f463ae76f12b117361c \[root@docker \~\]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 9f389c98fbd2 registry "/entrypoint.sh /etc..." 14 seconds ago Up 12 seconds 0.0.0.0:5000-\>5000/tcp, :::5000-\>5000/tcp hardcore_saha #推送push #把当前镜像 nginx:v2 推送到 5000 端口 \[root@docker \~\]# docker tag nginx:v2 172.25.254.5:5000/nginx.v3 \[root@docker \~\]# docker push 172.25.254.5:5000/nginx.v3 Using default tag: latest The push refers to repository \[172.25.254.5:5000/nginx.v3

Get "https://172.25.254.5:5000/v2/": http: server gave HTTP response to HTTPS client

默认用 https 的方式：得做认证

root@docker \~\]# #也可以不用https，而用http的方式，必须得配置非加密端口信息。/etc/docker/daemon.json \[root@docker \~\]# vim /etc/docker/daemon.json \[root@docker \~\]# cat /etc/docker/daemon.json { "insecure-registries" : \["http://172.25.254.5:5000"

}

root@docker \~\]# systemctl restart docker \[root@docker \~\]# docker push 172.25.254.5:5000/nginx.v3 Using default tag: latest The push refers to repository \[172.25.254.5:5000/nginx.v3
