1、部署简介

官网介绍的Harbor部署方式共三种

  • Online installer：在线安装，由于网速等原因，本文不做介绍
  • Offline installer: 离线安装
  • OVA installer: 使用VMware自家的虚拟机技术部署，本文不做介绍

2、安装步骤

安装分以下三步
1. 下载软件包；
1. 配置harbor.cfg;
1. 运行 install.sh安装harbor

安装文件下载地址：
https://github.com/vmware/harbor/releases

下载后解压文件包

$ tar xvf harbor-offline-installer-<version>.tgz

然后配置./harbor/harbor.cfg 配置文件

配置项分为必配和选配：

必选：

  • hostname: 主机名，用来访问UI和registry服务，建议用IP地址；
  • ui_url_protocol: (http 或 https. 默认 http)http协议；
  • db_password：MySQL的密码；
  • max_job_workers: (默认3) job service中worker的最大数量；
  • customize_crt：(on or off. 默认 on)是否创建私钥；
  • ssl_cert_key：是否创建公钥；
  • secretkey_path：秘钥路径；
  • log_rotate_count：日志存储版本
  • log_rotate_size：日志存储容量

选配本文不做介绍；

官方的安装非常简单，配置完成后，执行安装命令，即可自动完成安装

$ sudo ./install.sh

安装完成后，可以使用访问部署IP的80端口进入UI界面，默认管理员：admin/Harbor12345

使用docker登陆后，即可push镜像到Harbor中

$ docker login reg.yourdomain.com
$ docker push reg.yourdomain.com/myproject/myrepo:mytag

注意：
1、在docker中，必须修改配置文件 /etc/sysconfig/docker 讲OPTION中加入选项“–selinux-enabled=false”和“–insecure-registry 172.16.7.48 ”才能登陆成功
2、在push镜像时，仓库后第一个分隔符后的内容必须在Harbor中创建项目才能push成功，否则会报“denied: requested access to the resource is denied”错误，例如“ docker push 172.16.7.48/google_containers/pause-amd64:3.0”之前，一定要创建名为google_containers的project

3、安装过程代码解析

首先分析install.sh的代码

install.sh的代码非常简单，首先会判断安装环境是否完备

h2 "[Step $item]: checking installation environment ..."; let item+=1
check_docker
check_dockercompose

然后检查用户可选的安装选项，之后调用同目录名为prepare的Python脚本进行环境准备工作，该脚本主要对数据库、依赖等做校验和自动准备工作，具体代码不做分析

h2 "[Step $item]: preparing environment ...";  let item+=1
if [ -n "$host" ]
then
    sed "s/^hostname = .*/hostname = $host/g" -i ./harbor.cfg
fi
prepare_para=
if [ $with_notary ] && [ ! $harbor_ha ]
then
    prepare_para="${prepare_para} --with-notary"
fi
if [ $with_clair ]
then
    prepare_para="${prepare_para} --with-clair"
fi
if [ $harbor_ha ]
then
    prepare_para="${prepare_para} --ha"
fi
./prepare $prepare_para
echo ""

最后使用docker-compose完成安装，并检验安装的正确性

h2 "[Step $item]: starting Harbor ..."
if [ $harbor_ha ]
then
    mv docker-compose.yml docker-compose.yml.bak 
    cp ha/docker-compose.yml docker-compose.yml
    mv docker-compose.clair.yml docker-compose.clair.yml.bak
    cp ha/docker-compose.clair.yml docker-compose.clair.yml
fi
docker-compose $docker_compose_list up -d

protocol=http
hostname=reg.mydomain.com

if [[ $(cat ./harbor.cfg) =~ ui_url_protocol[[:blank:]]*=[[:blank:]]*(https?) ]]
then
protocol=${BASH_REMATCH[1]}
fi

if [[ $(grep 'hostname[[:blank:]]*=' ./harbor.cfg) =~ hostname[[:blank:]]*=[[:blank:]]*(.*) ]]
then
hostname=${BASH_REMATCH[1]}
fi
echo ""

success $"----Harbor has been installed and started successfully.----

Now you should be able to visit the admin portal at ${protocol}://${hostname}.

接着分析docker-compose的yaml文件

首先，启动log容器，接管所有log的收集工作，因此，在使用docker log命令查看容器的日志时，会出现报错

"logs" command is supported only for "json-file" and "journald" logging drivers (got: syslog)

该报错为正常现象，要查看Harbor日志，可以直接查看部署机器的/var/log/harbor/*.log文件

启动日志容器配置如下：

log:
    image: vmware/harbor-log:v1.4.0
    container_name: harbor-log 
    restart: always
    volumes:
      - /var/log/harbor/:/var/log/docker/:z
      - ./common/config/log/:/etc/logrotate.d/:z
    ports:
      - 127.0.0.1:1514:10514
    networks:
      - harbor

启动日志文件后，依次启动其他容器，并将之前初始化的各种配置文件通过挂载的方式放进容器中，容器较多，只举例一个：

adminserver:
    image: vmware/harbor-adminserver:v1.4.0
    container_name: harbor-adminserver
    env_file:
      - ./common/config/adminserver/env
    restart: always
    volumes:
      - /data/config/:/etc/adminserver/config/:z
      - /data/secretkey:/etc/adminserver/key:z
      - /data/:/data/:z
    networks:
      - harbor
    depends_on:
      - log
    logging:
      driver: "syslog"
      options:  
        syslog-address: "tcp://127.0.0.1:1514"
        tag: "adminserver"

上述配置中可以看出，网络是用名为Harbor的docker网络，日志驱动使用syslog的方式。

值得注意的是，若网络未创建，则docker会自动创建网络

  Kubernetes users can easily deploy pods with images stored in Harbor. The settings are similar to that of another private registry. There are two major issues:
