一 ：整体工作流程
工作机制.jpg
注意：这里为了清晰将docker 的客户端和服务端（docker daemon）分开了，实际一般都在一台机器上。当然也有分开部署的。
docker 客户端通过命令（api）向docker server 发送请求，docker server 与私有仓库交互完成用户的请求，docker push / pull
二 ：安装部署
2.1 安装docker
这里为了后面的k8s 集群安装 ，安装docker 18.06版本。
1.安装yum-utils （如有可省略）
yum install -y yum-utils
2.设置 docker yum 源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
- 版本预览&安装
yum list docker-ce --showduplicates | sort -r
yum install -y docker-ce-18.06.1.ce-3.el7
4.启动&设置开机启动
systemctl start docker
systemctl enable docker
5.查看docker 版本
docker version
[root@k8s-node1 docker]# docker version
Client:
Version: 18.06.1-ce
API version: 1.38
Go version: go1.10.3
Git commit: e68fc7a

3.1 Harbor 安装
1.Harbor 镜像 依赖 docker-compose 管理
上GitHub下载最新的release版本https://github.com/vmware/harbor/releases
docker-compose 版本 ：https://github.com/docker/compose/releases/
这里下载的是
v1.7.1
下载 Harbor online installer
-rw-r--r--. 1 root root 381 2月 27 17:15 1
-rw-------. 1 root root 1423 8月 28 2018 anaconda-ks.cfg
drwxr-xr-x. 3 root root 251 2月 28 11:56 harbor
-rw-r--r--. 1 root root 163595 2月 28 14:37 harbor-online-installer-v1.7.1.tgz
- 解压得到harbor
tar -zxvf harbor-online-installer-v1.7.1.tgz
3.进行最简单配置
cd harbor
-rw-r--r--. 1 root root 238 2月 28 11:56 1
drwxr-xr-x. 4 root root 37 2月 27 17:23 common
-rw-r--r--. 1 root root 939 1月 7 13:53 docker-compose.chartmuseum.yml
-rw-r--r--. 1 root root 975 1月 7 13:53 docker-compose.clair.yml
-rw-r--r--. 1 root root 1434 1月 7 13:53 docker-compose.notary.yml
-rw-r--r--. 1 root root 5608 1月 7 13:53 docker-compose.yml
-rw-r--r--. 1 root root 8031 2月 28 11:49 harbor.cfg
-rwxr-xr-x. 1 root root 5739 1月 7 13:53 install.sh
-rw-r--r--. 1 root root 11347 1月 7 13:53 LICENSE
-rw-r--r--. 1 root root 748160 1月 7 13:53 open_source_license
-rwxr-xr-x. 1 root root 36337 1月 7 13:53 prepare
#配置 harbor.cfg
vim harbor.cfg
#设置hostname
#This attribute is for migrator to detect the version of the .cfg file, DO NOT MODIFY!
_version = 1.7.0
#The IP address or hostname to access admin UI and registry service.
#DO NOT use localhost or 127.0.0.1, because Harbor needs to be accessed by external clients.
#DO NOT comment out this line, modify the value of "hostname" directly, or the installation will fail.
hostname = xxx.com（或者设置ip 192.168.229.20）
4.安装
./install.sh
等待docker-compose 下载相关的docker image，默认安装完成后会自动运行相关镜像
docker ps #查看

这里使用了nginx，默认80端口提供服务。
5.如需重启/或者停止 Harbor

6.UI 界面登陆 admin/Harbor12345 (harbor.cfg 可查看/修改admin 密码)
http://harborserver[ip]-> 192.168.x.20

4.1 push 镜像到harbor 私有仓库
1 .设置docker 私有仓库
#如果没有 daemon.json 就是创建
vim /etc/docker/daemon.json
{
"insecure-registries": ["192.168.229.20"]
}
如果不设置该私服地址会出现 xxxx 443 类似的错误，也就是
Error response from daemon: Get https://192.168.x.20/v1/users/: dial tcp 192.168.229.20:443: getsockopt: connection refused
harbor 默认使用 https ，这里的配置就是 告诉 docker daemon 支持 http 访问方式，并在设置了代理服务器地址。简单点就是配置私服地址，这个地址也可以作为镜像仓库（理解可能不准确，请勿深究!）
- 登陆 到 harbor （类似登陆github）
docker login 192.168.229.20
命令行会提示 输入 username/password，可以是 admin/Harbor12345
[root@k8s-node1 docker]# docker login 192.168.229.20
Username: admin
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
