这篇文章主要介绍了kubernetes中Harbor有什么用，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
镜像的存储harbor使用的是官方的docker registry(v2命名是distribution)服务去完成。harbor在docker distribution的基础上增加了一些安全、访问控制、管理的功能以满足企业对于镜像仓库的需求。harbor以docker-compose的规范形式组织各个组件，并通过docker-compose工具进行启停。
docker的registry是用本地存储或者s3都是可以的，harbor的功能是在此之上提供用户权限管理、镜像复制等功能，提高使用的registry的效率。Harbor的镜像拷贝功能是通过docker registry的API去拷贝，这种做法屏蔽了繁琐的底层文件操作、不仅可以利用现有docker registry功能不必重复造轮子，而且可以解决冲突和一致性的问题。
## 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.

#Determine whether or not to generate certificate for the registry's token.
#If the value is on, the prepare script creates new root cert and private key
#for generating token to access the registry. If the value is off the default key/cert will be used.
#This flag also controls the creation of the notary signer's cert.

#The path of cert and key files for nginx, they are applied only the protocol is set to https
ssl_cert = /mnt/harbor/cert/server.crt

#Admiral's url, comment this attribute, or set its value to NA when Harbor is standalone

#Log files are rotated log_rotate_count times before being removed. If count is 0, old versions are removed rather than rotated.
log_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.
