        Harbor（Harbor Container Registry）是一个开源的企业级容器镜像注册中心（Container Registry），旨在提供安全、可靠、高度可扩展的容器镜像管理和分发解决方案。Harbor支持Docker镜像，并提供了多种功能，适用于容器化应用的构建、部署和管理。

 看到这里有小伙伴不明白有docker的，可以去看看这篇文章，对小白非常的友好，内容非常详细。容器化奇迹：打开创新之门，加速业务发展的秘密武器

        在构建镜像仓库之前，我们先了解一下仓库的类型

一、仓库类型

市面上还有很多很多仓库类型，今天我们就用开源的最经典的harbor仓库，为大家讲讲如何构建以及如何使用harbor仓库

二、Harbor组件说明

在使用之前呢，我们先来了解一下harbor的原理，以及各个组件之间的关系

  • redis
    • 负责存储会话信息
  • harbor-db
    • 负责存储仓库数据(项目名称、镜像名称)
  • registry
    • 镜像的上传、下载
  • Log collector
    • 记录日志
  • harbor-core
    • 提供web UI界面
    • 颁发令牌token
    • webhook
      • 负责搜集镜像变化的信息，通知给UI进行展示
  • proxy
    • 提供反向代理
  • Job service
    • 提供镜像复制功能

三、harbor单机版部署

1、添加主机名解析
[root@harbor ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.140.11	harbor.linux.com
2、安装docker
[root@harbor ~]# rpm -q docker-ce
docker-ce-20.10.7-3.el7.x86_64

修改镜像下载路径
[root@harbor ~]# cat /etc/docker/daemon.json 
{
    "registry-mirrors": ["http://f1361db2.m.daocloud.io"]
}
3、安装docker-compose
这里已经提前下好了docker-compose，直接移动到bin目录下生效
[root@harbor ~]# mv docker-compose /usr/local/bin/
[root@harbor ~]# chmod a+x /usr/local/bin/docker-compose
4、安装harbor

harbor的下载地址：https://github.com/goharbor/harbor/tags

这里也已经提前下载好了harbor压缩包
[root@harbor ~]# tar xf harbor-offline-installer-v2.2.2.tgz 
[root@harbor ~]# cp harbor/harbor.yml.tmpl harbor/harbor.yml
5、配置CA为harbor签发证书/生成V3证书
1) 创建CA证书
mkdir /opt/ssl
cd /opt/ssl
openssl genrsa -out ca.key 4096
ls
openssl req -x509 -new -nodes -sha512 -days 3650  -subj "/CN=harbor.linux.com"  -key ca.key  -out ca.crt
2) 为harbor服务器创建证书
openssl genrsa -out server.key 4096

openssl req  -new -sha512  -subj "/CN=harbor.linux.com"  -key server.key  -out server.csr
3）创建v3.ext文件
[root@localhost ssl]# cat v3.ext 
 authorityKeyIdentifier=keyid,issuer
 basicConstraints=CA:FALSE
 keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
 extendedKeyUsage = serverAuth 
 subjectAltName = @alt_names
 [alt_names]
 DNS.1=harbor.linux.com

[root@localhost ssl]# openssl x509 -req -sha512 -days 3650 -extfile v3.ext -CA ca.crt -CAkey ca.key -CAcreateserial -in server.csr -out server.crt
6、编辑harbor配置文件
[root@harbor harbor]# vim harbor.yml

hostname: harbor.linux.com

# http related config
http:
  # port for http, default is 80. If https enabled, this port will redirect to https port
  port: 80

# https related config
https:
  # https port for harbor, default is 443
  port: 443
  # The path of cert and key files for nginx
  certificate: /opt/ssl/server.crt
  private_key: /opt/ssl/server.key
7、启动harbor

四、访问harbor

https://harbor.linux.com

  • 创建项目
  • 创建用户
  • 用户授权
1、上传镜像
1) 登录仓库
Harbor仓库启用了https后，docker服务器要能正常登录访问仓库，需要将harbor的证书拷贝到docker服务器

[root@test ~]# mkdir /etc/docker/certs.d/harbor.linux.com -p

[root@harbor ~]# scp -a /opt/ssl/harbor.crt root@192.168.140.10:/etc/docker/certs.d/harbor.linux.com
[root@localhost ~]# docker login harbor.linux.com
Username: sam
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
2) 上传镜像
[root@localhost ~]# docker tag nginx:1.14 harbor.linux.com/project_yw/nginx:1.14 
[root@localhost ~]# docker push harbor.linux.com/project_yw/nginx:1.14

3)查看上传的镜像


五、部署Harbor高可用集群

1、高可用方案介绍

  • 利用Harbor自带的复制功能
    • 两个harbor节点在进行镜像复制时，如果其中一个节点故障, 此时有新镜像的话，并不会复制到故障节点，而且故障的harbor修复后也不会自动复制数据，会导致数据不一致问题
  • 基于共享存储的方式实现
    • 将数据库、redis独立出来
      • harbor 1.6版本后，数据库仅支持postgreSQL
    • 利用共享存储(nfs, ipsan, glusterfs)存储镜像

2、部署Harbor高可用集群

1) 环境描述

192.168.140.11 harbor服务器
192.168.140.13 harbor服务器
192.168.140.12 NFS、Redis、PostgreSQL

2) 在两台Harbor服务器分别安装docker、docker-compose、harbor

3) 配置NFS服务器
[root@share_storage ~]# mkdir /data/harbor -p
[root@share_storage ~]# chmod o+w /data/harbor/
[root@share_storage ~]# yum install -y nfs-utils rpcbind 
[root@share_storage ~]# vim /etc/exports
[root@share_storage ~]# cat /etc/exports
/data/harbor	192.168.140.11(rw,no_root_squash)   192.168.140.13(rw,no_root_squash)
 
[root@share_storage ~]# systemctl start nfs-server
[root@share_storage ~]# systemctl enable nfs-server.service 
Created symlink from /etc/systemd/system/multi-user.target.wants/nfs-server.service to /usr/lib/systemd/system/nfs-server.service.

[root@share_storage ~]# showmount -e localhost 
Export list for localhost:
/data/harbor 192.168.140.13,192.168.140.11
3) 配置harbor服务挂载NFS存储
[root@harbor_01 ~]# yum install -y nfs-utils 

[root@harbor_01 ~]# vim /etc/fstab 
192.168.140.12:/harbordata	/data	nfs	defaults 0 0

[root@harbor_01 ~]# df -hT | grep nfs
192.168.140.12:/harbordata nfs4       18G  3.0G   15G  18% /data
4) 部署redis服务
[root@share_storage ~]# yum install -y redis
[root@share_storage ~]# vim /etc/redis.conf 
bind 192.168.140.12
daemonize yes
[root@share_storage ~]# systemctl start redis
[root@share_storage ~]# systemctl enable redis
[root@share_storage ~]# netstat -antp | grep redis
tcp        0      0 192.168.140.12:6379     0.0.0.0:*               LISTEN      17493/redis-server
5) 部署postgreSQL
a. 安装postgreSQL
[root@storage ~]# yum install -y cmake gcc gcc-c++ perl readline readline-devel openssl openssl-devel zlib zlib-devel ncurses-devel readline readline-devel zlib zlib-devel
[root@storage ~]# wget https://ftp.postgresql.org/pub/source/v12.2/postgresql-12.2.tar.gz
[root@storage ~]# tar xf postgresql-12.2.tar.gz 
[root@storage ~]# cd postgresql-12.2/
[root@storage ~]#./configure --prefix=/usr/local/postsql
[root@storage ~]# make && make install
b. 初始化postgreSQL
[root@storage ~]# useradd postgres
[root@storage ~]# mkdir -p /work/harbor-db/{data,temp,log}
[root@storage ~]# chown -R postgres.postgres /work/harbor-db
[root@storage ~]# /usr/local/postgresql/bin/initdb --username=postgres -D /work/harbor-db/data/
c. 编辑postgreSQL配置文件
[root@storage ~]# vim /work/harbor-db/data/postgresql.conf 

data_directory = '/work/harbor-db/data'

listen_addresses = '*'          
port = 5432                           
max_connections = 100   

unix_socket_directories = '/work/harbor-db/temp'
unix_socket_group = ''
unix_socket_permissions = 0777

shared_buffers = 128MB

timezone = 'Asia/Shanghai'
 
logging_collector = on
log_directory = '/work/harbor-db/log'
log_rotation_size = 1GB
log_timezone = 'Asia/Shanghai'
log_min_duration_statement = 100
d. 指定允许远程连接数据库的客户端
[root@storage ~]# tail -n 2 /work/harbor-db/data/pg_hba.conf 
host    all		harbor          192.168.140.11/24                 trust
host    all		harbor		192.168.140.13/24                 trust
e. 启动数据库
[root@storage ~]# su - postgres
[root@storage ~]# /usr/local/postgresql/bin/pg_ctl -D /work/harbor-db/data/ -l /work/harbor-db/log/start.log start

[postgres@storage ~]$ netstat -antp | grep 5432
tcp        0      0 0.0.0.0:5432            0.0.0.0:*               LISTEN      32215/postgres
f. 创建harbor需要的数据库及远程连接用户
[root@storage ~]# /usr/local/postgresql/bin/psql -h 127.0.0.1 -p 5432 -U postgres

postgres=# \password postgres
Enter new password: 
Enter it again: 

postgres=# create user harbor with password 'redhat';
CREATE ROLE

postgres=# CREATE DATABASE harbor;
CREATE DATABASE

postgres=# create database harbor_clair;
CREATE DATABASE

postgres=# create database harbor_notary_server;
CREATE DATABASE

postgres=# create database harbor_notary_signer; 
CREATE DATABASE
harbor		
postgres=# GRANT ALL ON DATABASE harbor to harbor;           
GRANT

postgres=# GRANT ALL ON DATABASE harbor_clair to harbor;           
GRANT

postgres=# GRANT ALL ON DATABASE harbor_notary_server to harbor;            
GRANT

postgres=# GRANT ALL ON DATABASE harbor_notary_signer to harbor;                    
GRANT
g. 远程主机测试连接数据库
[root@harbor_02 ~]# psql -h 192.168.140.12 -p 5432 -U harbor -W
6、安装harbor
[root@harbor_01 ~]# tar xf harbor-offline-installer-v2.2.1.tgz
7、编辑harbor配置文件
[root@harbor_02 ~]# vim harbor/harbor.yml

hostname: harbor.linux.com

注释https相关配置，本案例中没有配置证书
#https:
	# port: 443
	# certificate: /usr/local/harbor/ssl/harbor.ssl	
	# private_key: /usr/local/harbor/ssl/harbor.key

data_volume: /data

harbor_admin_password: Harbor12345


注释或删除harbor自带的数据库配置，后续配置外部数据库连接
#database:
	# password: root123
	# max_idle_conns: 50
	# max_open_conns: 1000

配置harbor连接外部postgresql数据库
external_database:
  harbor:
    host: 192.168.140.12
    port: 5432
    db_name: harbor
    username: harbor
    password: redhat
    ssl_mode: disable
    max_idle_conns: 2
    max_open_conns: 0
  notary_signer:
    host: 192.168.140.12
    port: 5432
    db_name: harbor_notary_signer
    username: harbor
    password: redhat
    ssl_mode: disable
  notary_server:
    host: 192.168.140.12
    port: 5432
    db_name: harbor_notary_server
    username: harbor
    password: redhat
    ssl_mode: disable

配置连接外部redis存储会话信息
external_redis:
   host: 192.168.140.12:6379
   password:
   
   registry_db_index: 1
   jobservice_db_index: 2
   chartmuseum_db_index: 3
   trivy_db_index: 5
   idle_timeout_seconds: 30
8、启动harbor
[root@harbor_01 harbor]# ./prepare
[root@harbor_01 harbor]# ./install.sh 

[root@harbor_02 harbor]# docker ps -a
CONTAINER ID   IMAGE                                COMMAND                  CREATED          STATUS                             PORTS                                                                            NAMES
