公有仓库和私有仓库：

速度：公有仓库走的公网，速度较慢；私有仓库走的是内网，即局域网；

安全性：公有仓库存放在公共硬盘上；私有仓库存在自己服务器硬盘上。

公有仓：

最权威的，但速度比较慢：

https://hub.docker.com/

首先登陆：

$ docker login -usmallsoup 
Password: 
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

打标签，push镜像到hub仓库：

docker tag zookeeper:3.5 smallsoup/zookeeper:3.5
docker push smallsoup/zookeeper:3.5

已push成功，可以在hub上看到：

私有仓：

用docker提供的registry在本地搭建私有仓：

docker pull registry:2.5.2
docker run -d -p 5000:5000 registry:2.5.2
docker tag zookeeper:3.5 localhost:5000/zookeeper:3.5
docker push zookeeper:3.5 localhost:5000/zookeeper:3.5

因没有设置安全性，所以直接可以push上去。

由于是本地仓库，所以pull的速度很快。

[root@localhost micro-service]# docker pull localhost:5000/zookeeper:3.5
3.5: Pulling from zookeeper
Digest: sha256:3474ec46da9db9dc27a431f9645a2df9c91d5b969f591fe0ccd4c40f2bfd1579
Status: Image is up to date for localhost:5000/zookeeper:3.5

但是这个私有仓不能满足我们的需求，生产线上万一该私有仓服务器故障，其他服务器也无法接管。再者，也没有页面可以便于管理。

业内出现的harbor，主要提供 Dcoker Registry 管理UI，可基于角色访问控制, AD/LDAP 集成，日志审核等功能，完全的支持中文，非常适用于生产环境。

harbor私有仓库搭建

github地址：

https://github.com/goharbor/harbor/releases

下载地址：

https://storage.googleapis.com/harbor-releases/harbor-offline-installer-v1.5.3.tgz

这个链接速度太慢，可以在这里下载：

http://harbor.orientsoft.cn/

以下使用的harbor版本是harbor-offline-installer-v1.5.0.tgz

首先解压：

tar -zxf harbor-offline-installer-v1.5.0.tgz

然后运行./install脚本进行安装，如果需要特殊设置，可以先修改harbor.cfg和docker-compose.yml后在进行./install安装操作

ERROR: Encountered errors while bringing up the project.

安装过程中报以上错误，是因为服务器上已经有了名为redis的容器名，和harbor将要安装的redis容器名重名，需要rename服务器上已有的redis容器名为micro-service-redis：

$ docker ps -a --filter name=redis
CONTAINER ID        IMAGE                              COMMAND             CREATED             STATUS              PORTS                    NAMES

$ docker rename redis micro-service-redis 
$ docker ps -aq --filter name=redis
c3813d66ccad

$ docker ps -a --filter name=redis

然后重新执行./install

If you encounter this issue regularly because of slow network conditions, consider setting COMPOSE_HTTP_TIMEOUT to a higher value (current value: 60).

又报以上的错，可能是由于网络问题，导致失败，重新./install试试：

 ----Harbor has been installed and started successfully.----

Now you should be able to visit the admin portal at http://hub.smallsoup.com. 
For more details, please visit https://github.com/vmware/harbor .

成功了。

可以访问harbor部署服务器IP:docker-compose.yml中80映射到宿主机上的端口；

用户名是admin，密码是harbor.cfg中harbor_admin_password的值访问管理页面：

可以创建一个私有仓库micro-service：

在系统管理->用户管理中添加用户，然后点开上一步创建的项目-->>成员-->>新建成员，并设置权限。

项目管理员：有pull和push以及项目其他管理权限；

开发人员：有pull和push权限；

访客：只有pull权限。

将该项目的各个微服务image push到harbor的micro-service项目里：

打标签：

docker tag openjdk:8-jre 192.168.1.103:80/micro-service/openjdk:8-jre

查看镜像：

$ docker images |grep -v "vmware" | grep open

push镜像：

$ docker push 192.168.1.103:80/micro-service/openjdk:8-jre
The push refers to repository [192.168.1.103:80/micro-service/openjdk]
Get https://192.168.1.103:80/v2/: http: server gave HTTP response to HTTPS client

push报错。由于默认采用的是http协议，即harbor.cfg中的ui_url_protocol值。https的比较麻烦，需要生成证书等步骤，可以参考：

为Harbor设置Https

http://gapme.cn/2017/10/25/harbor-ui-https/

这里暂且用http的方式。

以上报错解决办法：

在”/etc/docker/“目录下，创建”daemon.json“文件。在文件中写入：

{
  "insecure-registries": [
        "hub.smallsoup.com:80",
        "192.168.1.103:80"
  ]
}

重启docker：

systemctl restart docker

docker重启后，./install或者docker-compose down;docker-compose up -d重启harbor即可。

将基础镜像和各个服务镜像push到库上：

题外话：

在安装过程中，将80端口映射到宿主机的8081端口，push的时候遇到很多问题（报错80端口连接拒绝，大概就是这个issue

https://github.com/goharbor/harbor/issues/192），查找了很多资料，还是放弃了，最后映射到宿主机80端口，push一切ok。

由于用域名的方式push得设置hosts以及端口转发，比较麻烦，以上采用了IP:PORT方式：

删除用域名打的标签：

docker rmi -f hub.smallsoup.com:80/micro-service/openjdk:8-jre
