曾无好事来相访，赖尔高文一起予。这篇文章主要讲述docker仓库相关的知识，希望能为你提供帮助。
?本地镜像上传至官方docker仓库?????
docker仓库:??https://hub.docker.com/??
#登陆
docker login https://hub.docker.com/
cat .docker/config.json
docker images
docker tag镜像Iddocker.io/taowenwu/centos-nginx
docker push docker.io/taowenwu/centos-nginx
?docker-分布式harbor(https)安装?
安装参考：??https://blog.51cto.com/u_14814545/5052617??
harbor是一个用于存储和分发docker镜像的企业级registry(注册)服务器,由vmware开源
作为一个企业级私有registry服务器
harbor支持安装在多个registry节点的镜像资源复制。
官网地址:??https://vmware.github.io/harbor/cn/??
官方github :??https://github.com/vmware/harbor??
#功能：
1.基于角色的访问控制: 用户与docker镜像仓库通过"项目"进行组织管理,一个用户可以对多个镜像仓库在同一命名空间(project)里有不同的权限
2.镜像复制：镜像可以在多个registry实例中复制(同步)
3.图形化用户界面
4.ad/ldap：harbor可以集成企业内部已有的ad/ldap,用于鉴权认证管理
5.审计管理：所有针对镜像仓库的操作都可以被记录追溯
6.国际化
7.restful api：提供给管理员对于harbor更多的操控,使得与其他管理软件集成变得更容易部署简单
?单机docker registry?
docker registry作为docker的核心组件之一,负责镜像内容的存储与分发,
docker pull 以及push命令都是将直接与registry进行交互
docker1.6版本开始支持registry2.0
docker1.8发布,docker hub 正式启用2.1版本registry
docker1.5和之前的版本无法读取2.0的镜像
registry2.4版本之后支持回收站机制,也就是可以删除镜像
【docker仓库】基于官方registry搭建本地私有仓库
?直接启动容器?
#1.拉取镜像
docker pull registry:2
#2.启动容器
docker run -d -p 5000:5000 --restart=always --name registry1\\
-v /usr/local/registry:/var/lib/registryregistry:2
#3.测试上传
root@ubuntu:/docker# docker push 192.168.47.105:5000/hello-world
-----------------------------------------------------------------------------
Using default tag: latest
The push refers to repository [192.168.47.105:5000/hello-world]

#4.测试下载
root@ubuntu:~# docker pull 192.168.47.105:5000/hello-world
Using default tag: latest
latest: Pulling from hello-world

#5.其他机器上测试下载
vim /lib/systemd/system/docker.service
---------------------------------------------
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --insecure-registry 192.168.47.105:5000

?设置有登录名及密码?
参考:??https://blog.csdn.net/weixin_46380571/article/details/108771308??
#1.创建登录用户及密码
mkdir /docker/auth -p
cd /docker
docker run --entrypoint htpasswd registry:2.6.2 -Bbn admin password > auth/htpasswd#注意这里,高版本的有问题，会出现下面问题1的情况
问题1：
docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "htpasswd": executable file not found in $PATH: unknown.
ERRO[0000] error waiting for container: context canceled
-----------------------
#2.启动docker registry
docker run -d -p 5000:5000 --restart=always --name registry1\\
-v /docker/auth:/auth \\
-e "REGISTRY_AUTH=htpasswd" \\
-e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \\
-e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd registry:2.6.2
#3.测试登录
root@ubuntu:/docker# docker login 192.168.47.105:5000
Username: testuser
Password:
Error response from daemon: Get "https://192.168.47.105:5000/v2/": http: server gave HTTP response to HTTPS client
出现这问题的原因是：Docker自从1.3.X之后docker registry交互默认使用的是HTTPS，但是搭建私有镜像默认使用的是HTTP服务，所以与私有镜像交时出现以上错误
vim /lib/systemd/system/docker.service
---------------------------------------------
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --insecure-registry 192.168.47.105:5000
---------------------------------------------
或
vim/etc/docker/daemon.json
