Docker搭建私有仓库harbor（docker 镜像仓库搭建）

• Harbor介绍

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。

Docker Harbor是一个企业级的Docker Registry服务，旨在提供安全、可靠的镜像存储和管理解决方案。以下是Docker
Harbor的一些关键特点：

1. 私有Registry：Docker Harbor允许用户搭建私有的Docker Registry，使得企业可以在自己的内部网络中安全地存储和管理Docker镜像。
2. 安全性：Docker Harbor提供了访问控制、用户和团队管理功能，以确保镜像的安全性。它支持用户身份验证、权限控制、安全扫描等功能，帮助用户保护他们的容器镜像不受未经授权的访问。
3. 可扩展性：Docker Harbor支持集群部署，可以轻松地扩展以应对大规模的容器镜像存储需求。
4. 镜像复制和同步：Docker Harbor允许用户在不同的Registry之间复制和同步镜像，方便用户在多个部署环境之间共享和管理镜像。
5. 审计和日志记录：Docker Harbor提供审计和日志记录功能，记录用户对镜像的操作，以帮助用户跟踪镜像的变更历史。 总的来说，Docker Harbor是一个功能强大的企业级Docker
   Registry服务，为用户提供了安全、可靠的方式来管理和存储Docker镜像。

1. 为harbor签发证书

[root@harbor ~]# hostnamectl set-hostname harbor && /bin/bash
[root@harbor ~]# mkdir /data/ssl -p
[root@harbor ~]# cd /data/ssl/#生成ca证书
#生成一个3072位的key，也就是私钥
[root@harbor ssl]# openssl genrsa -out ca.key 3072
Generating RSA private key, 3072 bit long modulus
...........++
.............++
e is 65537 (0x10001)
#生成一个数字证书ca.pem，3650表示证书的有效时间是3年，按箭头提示填写即可，没有箭头标注的为空：
[root@harbor ssl]# openssl req -new -x509 -days 3650 -key ca.key -out ca.pem
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:CH
State or Province Name (full name) []:BJ
Locality Name (eg, city) [Default City]:BJ
Organization Name (eg, company) [Default Company Ltd]:BJ
Organizational Unit Name (eg, section) []:BJ
Common Name (eg, your name or your server's hostname) []:CHONG
Email Address []:[e-mail]#生成域名的证书
#生成一个3072位的key，也就是私钥
[root@harbor ssl]# openssl genrsa -out harbor.key  3072
Generating RSA private key, 3072 bit long modulus
.++
..........................................................++
e is 65537 (0x10001)
#生成一个证书请求，一会签发证书时需要的，标箭头的按提示填写，没有箭头标注的为空：
[root@harbor ssl]# openssl req -new -key harbor.key -out harbor.csr
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:CH
State or Province Name (full name) []:BJ
Locality Name (eg, city) [Default City]:BJ
Organization Name (eg, company) [Default Company Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, your name or your server's hostname) []:harbor  #主机名
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
#签发证书
[root@harbor ssl]# openssl x509 -req -in harbor.csr -CA ca.pem -CAkey ca.key -CAcreateserial -out harbor.pem -days 3650
#显示如下说明证书发布完成
Signature ok
subject=/C=CH/ST=BJ/L=BJ/O=Default Company Ltd/CN=harbor
Getting CA Private Key

注：安装harbor需要docker，记得安装docker

2. 安装harbor

#创建harbor安装目录
[root@harbor ~]# mkdir /data/install -p
[root@harbor ~]# cd /data/install/
#上传harbor离线包到该目录：harbor-offline-installer-v2.3.0-rc3.tgz
#下载harbor离线包的地址：https://github.com/goharbor/harbor/releases/tag/
[root@harbor install]# ll
total 614492
-rw-r--r-- 1 root root 629238614 Apr 11 21:40 harbor-offline-installer-v2.3.0-rc3.tgz#解压该安装包
[root@harbor install]# tar -xf harbor-offline-installer-v2.3.0-rc3.tgz
[root@harbor install]# ll
total 614492
drwxr-xr-x 2 root root       122 Apr 11 21:42 harbor
-rw-r--r-- 1 root root 629238614 Apr 11 21:40 harbor-offline-installer-v2.3.0-rc3.tgz
[root@harbor install]# cd harbor
[root@harbor harbor]# ll
total 617800
-rw-r--r-- 1 root root      3361 Jun 17  2021 common.sh
-rw-r--r-- 1 root root 632593607 Jun 17  2021 harbor.v2.3.0.tar.gz

[root@harbor harbor]# cp harbor.yml.tmpl harbor.yml#修改配置
[root@harbor harbor]# vim harbor.yml

只修改三种地方 一个是主机名 一个是key和pem得位置

3. 安装docker-compose

上传docker-compose-Linux-x86_64文件到harbor机器

-rw-r--r-- 1 root root      7840 Jun 17  2021 harbor.yml.tmpl
-rwxr-xr-x 1 root root      2500 Jun 17  2021 install.sh
-rw-r--r-- 1 root root     11347 Jun 17  2021 LICENSE
-rwxr-xr-x 1 root root      1881 Jun 17  2021 prepare
