前言

dockerhub虽然很好，但是对公司的一些集体项目，不方便放上去，而且传输拉取时间慢等因素，便想到搭建本地docker仓库。正好docker官方有docker-registry支持本地仓库服务，不过可惜，只有服务后端，没有开源的ui。

使用docker-registry

仓库服务

​​docker run -itd --rm -p 5000:5000 -v /opt/data/registry:/tmp/registry registry​​ 开启docker服务,仓库服务运行在镜像里，并和宿主机通过5000联通

上传镜像

以alpine为例，
​​​docker image ls​​ 发现镜像列表里有个alpine，想要把他传到本地仓库里

​​docker tag ba58 localhost:5000/fwhezfwhez/alpine:latest​​ 将alpine tag一下，tag的格式是:仓库url/用户名/镜像名:标签

​​docker push localhost:5000/fwhezfwhez/alpine​​ 这样就推送完了

查询和拉取都得走api，也是蛮麻烦的。

web ui

选用了harbor，使用前需要确认以下条件:

  • linux
  • 40GB硬盘，双核，4GB MEM
  • 网络可达postgres数据库源(因为我在部署时，官方的postgres容器总是出问题，我定位不到呢)
  • 需要配置域名以及支持https(因为docker push走443)
  • 具备docker，docker-compose环境

下面就以上条件，列出我这里是怎么解决的。

  • 购买了一台腾讯云服务器，并成功登入控制台:
    ​​​https://console.cloud.tencent.com/cvm?backfrom=cvmdetai​​​ 购买后设计到了一些控制台上面的基本操作，这些初次入云的同学，可以选择一天,或者一个星期，半个月等短周期购买体验。
    购买后需要解决以下:
  1. 添加sudo用户，当然也可以直接使用root进行所有操作.
  2. 在控制台里，增加安全组，暴露服务器端口(22:文件传输scp，80:http，443:https, 5432:postgres, 6379:redis),短周期购买的可以直接暴露所有端口。
  • 安装docker,docker-compose，redis，并通过docker快捷安装postgres
    docker: ​​https://docs.docker.com/install/linux/docker-ce/centos/​​ docker-compose: ​​https://github.com/docker/compose/releases​​ redis:
    ​​yum install redis​​ ,
    ​​systemctl enable redis​​,
    ​​systemctl start redis​​ postgres:
    ​​docker pull postgres:latest​​,
    ​​docker run -tid --restart=on-failure:20 -p 5432:5432 postgres:latest​​​​docker exec -it <容器id> sh​​ 然后自行百度如何创建数据库,创建一个叫​​harbor​​的数据库作为数据源
  • 购买域名并添加解析，并申请免费的https证书
    域名: ​​https://console.cloud.tencent.com/domain​​ 证书和解析: ​​https://console.cloud.tencent.com/ssl​​ 得到证书以后，证书内的叫Nginx文件夹里面的2个文件(key,crt)通过scp进服务器
    ​​scp -P 22 xxx.key xxx@host:/path​​​​scp -P 22 xxx.crt xxx@host:/path​​
  • 安装harbor并部署至该服务器上,并通过域名可达
    官方参考:​​https://github.com/goharbor/harbor/blob/master/docs/installation_guide.md​​ 大致上是，下载offline版的harbor压缩文件，通过scp传到服务器上，再tar解压，修改解压后的文件夹里的harbor.yml,下面是我作了修改后的配置(数据库的host:xx.xxx.xx.xx需要写成你们自己的，hostname也是, certification和private_key分别是之前scp过去的证书路径)，供参考:
# Configuration file of Harbor

# The IP address or hostname to access admin UI and registry service.
# DO NOT use localhost or 127.0.0.1, because Harbor needs to be accessed by external clients.
hostname: ftcrone.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

  port: 443
  # The path of cert and key files for nginx

# Uncomment external_url if you want to enable external proxy
# And when it enabled the hostname will no longer used

# Harbor Storage settings by default is using /data dir on local filesystem
# Uncomment storage_service setting If you want to using external storage
# storage_service:
#   # ca_bundle is the path to the custom root ca certificate, which will be injected into the truststore
#   # of registry's and chart repository's containers.  This is usually needed when the user hosts a internal storage with self signed certificate.
#   ca_bundle:

# Log configurations

  # Log files are rotated log_rotate_count times before being removed. If count is 0, old versions are removed rather than rotated.
  rotate_count: 50
  # Log files are rotated only if they grow bigger than log_rotate_size bytes. If size is followed by k, the size is assumed to be in kilobytes. 
  # If the M is used, the size is in megabytes, and if G is used, the size is in gigabytes. So size 100, size 100k, size 100M and size 100G 
  # are all valid.
  rotate_size: 200M
  # The directory on your host that store log
  location: /var/log/harbor

#This attribute is for migrator to detect the version of the .cfg file, DO NOT MODIFY!

# Uncomment external_database if using external database.

在同级harbor.yml,执行 ​​install.sh​​​, ​​./install.sh​​,结束。

可以体验一下:
​​​https://ftcrone.com​​​ 不保证一直开放，可以去体验一下:
注册一个账号，添加一个项目，傻瓜操作，这个不示范。

  • 推送一个镜像进去
    ​​docker login ftcrone.com​​​ 用注册的账户登陆本harbor
    ​​docker tag alpine:latest ftcrone.com/zonst/alpine:latest​​​ 标签一下本地某个镜像
    ​​docker push ftcrone.com/zonst/alpine​​​ 推过去
