kubernetes下搭建harbor企业级docker仓库

前言

harbor是由vmware开源的企业级docker repository，提供私有仓库，安全认证，权限管理，漏洞扫描及仓库复制等多种功能，因为之前搭建的harbor在线上环境存在各种各样的问题（之前搭建的方式目前发现已被官方宣布弃用https://github.com/vmware/harbor/blob/master/docs/kubernetes_deployment.md，如ui显示不正常，权限认证不正常），于是近期抽空用官方推荐的helm方式对harbor进行重新部署，并替换掉线上harbor

准备

Kubernetes集群1.8+

Kubernetes Ingress Controller已启用(这里我们选用的traefik-ingress)

kubectl 客户端 1.8+

可选的持久化功能需要准备PV或者SC（我们这里使用nfs创建的PV和PVC，如果有条件使用SC的会更加方便）

部署过程

首先按照官方教程安装Helm，然后初始化Helm。

注意

： 初始化需要使用下面命令使用canary镜像，否则无法正常安装，会报错helm部署文件的格式不正确，目前这是一个已知issue:https://github.com/vmware/harbor/issues/4484

helm init --canary-image

如果你和我一样，在这之前已经用官方教程安装好了helm，则可使用下面命令更新helm server:

helm init --canary-image --upgrade

下载helm部署代码并进入harbor helm目录。

git clone https://github.com/vmware/harbor 
cd harbor/contrib/helm/harbor

推荐使用这个连接下载指定的文件夹，否则在网络不佳的情况下拉取全部代码会比较耗时:

更新helm dependency

harbor的helm部署依赖了postgresql的helm，在官方的安装文档没有明确说明，因为我也是第一次使用，直接按照官方文档说明安装，就会缺失postgresql的部署，导致整个服务无法启动

helm dependency update

安装harbor

这里官方提供了两种方式，Insecure和Secure，我这里选用的是Secure安全的部署方式，让harbor自己生成CA和SSL，简单方便。执行如下命令安装harbor:

helm install . --debug --name hub --set externalDomain=harbor.my.domain

externalDomain为外部能访问到harbor的域名，到目前为止，你可以在本地/etc/hosts中添加域名解析，从本地访问进行测试，待测试完成后再加入traefik-ingress中，当然你也可以直接在traefik-ingress中添加域名解析。

添加traefik-ingress的域名解析：

apiVersion: extensions/v1beta1

kind: Ingress

metadata:

name: traefik-default-ingress

namespace: default

annotations:

kubernetes.io/ingress.class: "traefik"

spec:

rules:

<ul><li>host: harbor.my.domain

http:

paths:

<ul><li>path: /

backend:

serviceName: my-release-harbor-ui

servicePort: 80

helm harbor自定义配置

注意： 我这里把所有自定义配置放到后面的附录中，供大家参考,同时可以点击https://github.com/Anteoy/harbor-helm/commit/226b296d130b4f956f8463eecf2aa473bc1e844c,查看我上传到github的自定义配置，从github阅读更清晰。

重要：在生产环境中需要持久化数据存储，否则pod重启或重建会造成数据丢失。如果有创建好的storageClass可以直接在values.yaml配置，如果没有或暂时不能使用SC的，比如我这里只有nfs，则需要像我一样多修改一些配置。另外,nfs其实在社区也有storageClass的驱动库，不过我看了下使用起来较为繁琐，于是这里仍然修改为使用nfs。

修改templates默认的namespace，注意需要修改依赖的chart文件夹下的postgresql-0.9-1.tgz压缩文件中的部署yaml模板，否则harbor的ui,register,mysql和postgresql不在一个namespace下，不能正常安装

注意修改postgresql的持久化数据卷，可参考https://github.com/kubernetes/charts/tree/master/stable/postgresql
