Harbor介绍与安装部署,并实现通过http和https协议【自签发SSL证书】访问,客户端如何通过Harbor镜像仓库实现镜像的上传【推送】与下载【拉取】。

 

Harbor介绍

Harbor,是一个英文单词,意思是港湾,港湾是干什么的呢,就是停放货物的,而货物呢,是装在集装箱中的,说到集装箱,就不得不提到Docker容器,因为docker容器的技术正是借鉴了集装箱的原理。所以,Harbor正是一个用于存储Docker镜像的企业级Registry服务。

Docker容器应用的开发和运行离不开可靠的镜像管理,虽然Docker官方也提供了公共的镜像仓库,但是从安全和效率等方面考虑,部署我们私有环境内的Registry也是非常必要的。Harbor是由VMware公司开源的企业级的Docker Registry管理项目,它包括权限管理(RBAC)、LDAP、日志审核、管理界面、自我注册、镜像复制和中文支持等功能。

 

机器规划

服务器名称(hostname)操作系统版本内网IP外网IP(模拟)安装软件
docker01 CentOS7.7 172.16.1.31 10.0.0.31 docker、Harbor
docker02 CentOS7.7 172.16.1.32 10.0.0.32 docker

 

SSL证书创建

如果要使用https访问Harbor。那么请按照如下生成SSL证书。

创建根证书

1 ## 创建CA私钥
2 openssl genrsa -out ca.key 2048
3 ## 制作CA公钥
4 openssl req -new -x509 -days 36500 -key ca.key -out ca.crt -subj "/C=CN/ST=BJ/L=BeiJing/O=BTC/OU=MOST/CN=zhang/emailAddress=ca@test.com"

选项参数说明:

genrsa 生成私钥

-out filename 标准输出到filename文件

req 生成证书请求

-new 生成新证书签署请求

-x509 专用于CA生成自签证书;不自签的时候不要加该选项

-days num 证书的有效期限

-key file 生成请求时用到的私钥文件

-out filename 标准输出到filename文件

subj内容详解:

1 C             = 国家
2 ST            = 省/3 L             = 城市
4 O             = Organization Name
5 OU            = Organizational Unit Name
6 CN            = Common Name
7 emailAddress  = test@email.address

 

证书签发

1 ## 创建私钥
2 openssl genrsa -out httpd.key 1024
3 ## 生成签发请求
4 openssl req -new -key httpd.key -out httpd.csr -subj "/C=CN/ST=BJ/L=BeiJing/O=BTC/OU=OPS/CN=zhang/emailAddress=zhang@test.com"
5 ## 使用CA证书进行签发
6 openssl x509 -req -sha256 -in httpd.csr -CA ca.crt -CAkey ca.key -CAcreateserial -days 36500 -out httpd.crt
7 ## 验证签发证书是否有效
8 openssl verify -CAfile ca.crt httpd.crt

 

生成结果如下图:

然后将httpd.key和httpd.crt,放到/etc/harbor/cert/目录下,后面会用到。

 

安装docker-ce

安装脚本如下

 1 [root@docker01 harbor]# pwd
 2 /root/harbor
 3 [root@docker01 harbor]# cat install_docker-ce.sh
 4 #!/bin/sh
 5 
 6 # 加载环境变量
 7 . /etc/profile
 8 . /etc/bashrc
 9 
10 ## 设置 docker yum repository
11 yum install -y yum-utils device-mapper-persistent-data lvm2
12 yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
13 
14 ## 安装docker
15 yum install -y docker-ce
16 # yum install -y docker-ce-19.03.8
17 
18 ## 启动docker服务,这样可以创建/etc/docker目录
19 systemctl start docker
20 
21 ## 配置daemon
22 ## 1、修改docker Cgroup Driver为systemd;2、日志格式设定
23 ## 如果不修改,可能会碰到如下错误
24 ## [WARNING IsDockerSystemdCheck]: detected "cgroupfs" as the Docker cgroup driver. The recommended driver is "systemd". 
25 ## Please follow the guide at https://kubernetes.io/docs/setup/cri/
26 cat > /etc/docker/daemon.json << EOF
27 {
28   "exec-opts": ["native.cgroupdriver=systemd"],
29   "log-driver": "json-file",
30   "log-opts": {
31     "max-size": "100m"
32   }
33 }
34 EOF
35 
36 ## 开机自启动
37 systemctl stop docker && systemctl daemon-reload && systemctl enable docker && systemctl start docker

 

安装docker-compose

此次,我们使用的是 1.25.5 版本。

harbor.yml配置文件修改内容【http访问】

 1 # 这里的hostname怎么配置
 2 # 1、如果所有机器都在一个局域网,那么配置内网IP
 3 # 2、如果机器跨网络,只能通过公网访问,那么配置本机外网IP或域名
 4 hostname: 172.16.1.31
 5 
 6 # http端口改为了5000,默认80端口
 7 http:
 8   # port for http, default is 80. If https enabled, this port will redirect to https port
 9   port: 5000
10 
11 # 将https注释掉,不然会报 ERROR:root:Error: The protocol is https but attribute ssl_cert is not set
12 # https related config
13 #https:
14   # https port for harbor, default is 443
15   #port: 443
16   # The path of cert and key files for nginx
17   #certificate: /your/certificate/path
18   #private_key: /your/private/key/path
19 
20 # admin用户的免密
21 harbor_admin_password: Harbor12345
22 
23 # 数据存储路径
24 data_volume: /data

 

harbor.yml配置文件修改内容【https访问】

放开了https配置,本次证书是自签发的。

 1 # 这里的hostname怎么配置
 2 # 1、如果所有机器都在一个局域网,那么配置内网IP
 3 # 2、如果机器跨网络,只能通过公网访问,那么配置本机外网IP或域名
 4 hostname: 172.16.1.31
 5 
 6 # http端口改为了5000,默认80端口
 7 http:
 8   # port for http, default is 80. If https enabled, this port will redirect to https port
 9   port: 5000
10 
11 # https related config
12 https:
13   # https port for harbor, default is 443
14   port: 443
15   # The path of cert and key files for nginx
16   certificate: /etc/harbor/cert/httpd.crt
17   private_key: /etc/harbor/cert/httpd.key
18 
19 # admin用户的免密
20 harbor_admin_password: Harbor12345
21 
22 # 数据存储路径
23 data_volume: /data

如果使用了https协议且端口是443,那么当使用http访问时,会自动跳转到https。

部署Harbor

修改完配置文件后,在的当前目录执行./install.sh,Harbor服务就会根据当前目录下的docker-compose.yml开始下载依赖的镜像,检测并按照顺序依次启动。

 1 [root@docker01 harbor]# ll
 2 total 662120
 3 drwxr-xr-x 3 root root        20 May 12 23:47 common
 4 -rw-r--r-- 1 root root      3398 Feb 10 14:18 common.sh
 5 -rw-r--r-- 1 root root 677974489 Feb 10 14:19 harbor.v1.10.1.tar.gz
 6 -rw-r--r-- 1 root root      5921 May 12 23:54 harbor.yml
 7 drwxr-xr-x 2 root root        24 May 12 23:47 input
 8 -rwxr-xr-x 1 root root      2284 Feb 10 14:18 install.sh
 9 -rw-r--r-- 1 root root     11347 Feb 10 14:18 LICENSE
10 -rwxr-xr-x 1 root root      1749 Feb 10 14:18 prepare
11 [root@docker01 harbor]# 
12 [root@docker01 harbor]# ./install.sh   # 启动harbor

 

启动结果如下图

 

停止与启动Harbor

如果修改了Harbor的配置文件harbor.yml,因为Harbor是基于docker-compose服务编排的,我们可以使用docker-compose命令重启Harbor。

未修改配置文件,重启Harbor命令:docker-compose start | stop | restart

当然个人建议:如果修改了harbor.yml文件,那么停止使用docker-compose down,启动使用 ./install.sh 。

浏览器访问

访问地址如下:

1 http 访问:http://10.0.0.31:5000/   或则  http://172.16.1.31:5000/
2 https访问:https://10.0.0.31/       或者  https://172.16.1.31/

备注:

1、由于我使用的Vmware虚拟机,因此10.0.0.0/24网段【模拟外网】和172.16.1.0/24网络【内网】都可以访问。生产环境是访问内网还是外网,视具体情况而定。

2、这里的访问地址和harbor.yml中配置的hostname值无关。

Harbor实现Docker镜像上传与下载

新建项目

根据你的项目名新建项目,这样才能将镜像推动到harbor镜像中心。

 

 

客户端http设置

Docker 默认不允许非 HTTPS 方式推送镜像。我们可以通过 Docker 的配置选项来取消这个限制。

如果直接【上传】或【拉取】镜像会失败,因为默认为https方式。

所有客户端都需要添加这个配置,然后重启 docker 服务。

 

 1 [root@docker01 ~]# vim /etc/docker/daemon.json
 2 {
 3   "exec-opts": ["native.cgroupdriver=systemd"],
 4   "log-driver": "json-file",
 5   "log-opts": {
 6     "max-size": "100m"
 7   },
 8   "insecure-registries": ["172.16.1.31:5000"]
 9 }
10 [root@docker01 ~]# systemctl restart docker   # 重启docker服务

 添加了 “insecure-registries”: [“172.16.1.31:5000”] 这行,其中172.16.1.31为内网IP地址。该文件必须符合 json 规范,否则 Docker 将不能启动。

如果在Harbor所在的机器重启了docker服务,记得要重新启动Harbor。

客户端登录Harbor

客户端登录Harbor。

# docker login 172.16.1.31:5000 -u admin -p Harbor12345

 

查看登录信息,这样客户端就可以直接拉取或者推送镜像了。

 1 [root@docker01 ~]# cat ~/.docker/config.json 
 2 {
 3     "auths": {
 4         "172.16.1.31:5000": {
 5             "auth": "YWRtaW46SGFyYm9yMTIzNDU="
 6         }
 7     },
 8     "HttpHeaders": {
 9         "User-Agent": "Docker-Client/19.03.8 (linux)"
10     }
11 }

 

Docker push镜像上传

1 [root@docker02 ~]# docker images 
2 REPOSITORY                     TAG                 IMAGE ID            CREATED             SIZE

4 [root@docker02 ~]# docker push 172.16.1.31:5000/zhang/nginx:1.17    # 上传镜像
5 The push refers to repository [172.16.1.31:5000/zhang/nginx]
