docker-3.私有仓库

仓库是集中存放镜像的地方

注册服务器是存放仓库的服务器，每个服务器上有多个仓库

搜索镜像

docker search ubuntu

从docker hub的ubuntu仓库下载ubuntu镜像

docker pull ubuntu

安装docker-distribution

yum install -y docker-distribution

启动服务并开机自启

systemctl enable docker-distribution

systemctl start docker-distribution

或

通过官方提供的registry镜像创建私有仓库

docker run -d -p 5000:5000 -v /data/registry:/var/lib/registry registry

-v把registry的容器路径/var/lib/registry映射到本机的 /data/registry

私有仓库IP为 192.168.200.102

上传镜像到私有仓库

标记镜像为192.168.200.102:5000/ubuntu:16.04.3

docker tag ubuntu:16.04.3 192.168.200.102:5000/ubuntu:16.04.3

docker images

docker client创建daemon.json文件

vim /etc/docker/daemon.json

{ "insecure-registries":["192.168.200.102:5000"] }

systemctl restart docker
