仓库就是集中存放镜像的地方，分为公共仓库和私有仓库，一个容易混淆的概念是注册服务器，实际上注册服务器是存放仓库的具体服务器，一个注册服务器可以有多个仓库，而每个仓库下面有多个镜像
官方仓库地址:DockerHub
使用docker login 命令来登录官方的公共仓库
[root@rsync131 ~]# docker login Login with your Docker ID to push and pull images from Docker Hub. If you don‘t have a Docker ID, head over to https://hub.docker.com to create one. Username: brianzjz Password: Login Succeeded 没有用户名密码的可以去官方注册一个
使用docker pull 命令下载镜像
[root@rsync131 ~]# docker pull nginx Using default tag: latest Trying to pull repository docker.io/library/nginx ... latest: Pulling from docker.io/library/nginx 802b00ed6f79: Pull complete e9d0e0ea682b: Pull complete d8b7092b9221: Pull complete Digest: sha256:24a0c4b4a4c0eb97a1aabb8e29f18e917d05abfe1b7a7c07857230879ce7d3d3 Status: Downloaded newer image for docker.io/nginx:latest
使用docker push 命令推送镜像
[root@rsync131 ~]# docker push brianzjz/nginx:v1.0 The push refers to a repository [docker.io/brianzjz/nginx] 579c75bb43c0: Mounted from library/nginx 67d3ae5dfa34: Mounted from library/nginx 8b15606a9e3e: Mounted from library/nginx v1.0: digest: sha256:c0b69559d28fb325a64c6c8f47d14c26b95aa047312b29c699da10380e90b4d7 size: 948
使用国内的仓库就是为了能提高下载的速度：想要达到火箭的速度 请点击：火箭加速器
这个私有仓库才是重点，在我们的企业中很多都会是自己去定制自己的镜像文件，有一些还必须不能对外开放的，也是能够为了提高在内网的下载速度，这样我们就要搭建自己的私有仓库了
安装docker后，可以通过官方提供的registry镜像来简单的搭建一套本地的私有仓库
[root@rsync131 ~]# mkdir -p /opt/data/docker/ # 创建存放镜像的目录 [root@rsync131 ~]# docker run -it -d -p 5000:5000 -v /opt/data/docker:/tmp/registry registry # 创建容器 -p指定端口 -v数据卷挂载 Unable to find image ‘registry:latest‘ locally Trying to pull repository docker.io/library/registry ... latest: Pulling from docker.io/library/registry d6a5679aa3cf: Pull complete ad0eac849f8f: Pull complete 2261ba058a15: Pull complete f296fda86f10: Pull complete bcd4a541795b: Pull complete Digest: sha256:5a156ff125e5a12ac7fdec2b90b7e2ae5120fa249cf62248337b6d04abc574c8 Status: Downloaded newer image for docker.io/registry:latest 6df20cdacf8d4a40ad3cbd3d310299650d41d0757b535130a0daa19f21ee1901 [root@rsync131 ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 6df20cdacf8d registry "/entrypoint.sh /e..." 8 seconds ago Up 7 seconds 0.0.0.0:5000->5000/tcp dazzling_golick
用另一台机器来测试上传下载私有仓库
[root@nfs133 ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
[root@nfs133 ~]# docker pull nginx
Using default tag: latest
Trying to pull repository docker.io/library/nginx ...

=================================================
[root@nfs133 ~]# docker push 192.168.73.131:5000/nginx_test
The push refers to a repository [192.168.73.131:5000/nginx_test]
Get https://192.168.73.131:5000/v1/_ping: http: server gave HTTP response to HTTPS client
这里执行的时候报错了，原因就是新版本的docker对安全性要求高了，会要求仓库支持SSL/TLS证书
解决方法：
修改daemon配置文件
[root@nfs133 ~]# vim /etc/sysconfig/docker
OPTIONS=‘--selinux-enabled --log-driver=journald --signature-verification=false # 原来的配置
修改为：
OPTIONS=‘--selinux-enabled --log-driver=journald --signature-verification=false --insecure-registry 192.168.73.131:5000‘
保存后，重启docker
[root@nfs133 ~]# systemctl restart docker
=================================================
# 重新执行push
[root@nfs133 ~]# docker push 192.168.73.131:5000/nginx_test
The push refers to a repository [192.168.73.131:5000/nginx_test]
