搭建Harbor企业级私有Docker镜像仓库部署

编程

 

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。

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

11yuminstall -y yum-utils device-mapper-persistent-data lvm2

12yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

13

14## 安装docker

15yuminstall -y docker-ce

16 # yuminstall -y docker-ce-19.03.8

17

18 ## 启动docker服务,这样可以创建/etc/docker目录

19systemctl 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/

26cat > /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}

34EOF

35

36## 开机自启动

37 systemctl stop docker && systemctl daemon-reload && systemctl enable docker && systemctl start docker

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

4hostname: 172.16.1.31

5

6# http端口改为了5000,默认80端口

7http:

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

21harbor_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

4hostname: 172.16.1.31

5

6# http端口改为了5000,默认80端口

7http:

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

12https:

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

20harbor_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 1223:47 common

4 -rw-r--r-- 1 root root 3398 Feb 1014:18 common.sh

5 -rw-r--r-- 1 root root 677974489 Feb 1014:19 harbor.v1.10.1.tar.gz

6 -rw-r--r-- 1 root root 5921 May 1223:54 harbor.yml

7 drwxr-xr-x 2 root root 24 May 1223:47 input

8 -rwxr-xr-x 1 root root 2284 Feb 1014:18install.sh

9 -rw-r--r-- 1 root root 11347 Feb 1014:18 LICENSE

10 -rwxr-xr-x 1 root root 1749 Feb 1014:18 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。

 

 

登录后页面

 

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 login172.16.1.31:5000 -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 }
