背景：
java程序员们想弄一个私有maven仓库，嗯 正常的是用nexus or artfactory? artfactory是两三年前听jfrog的讲座知道的，程序说他原来用的nexus。那就搞一个nexus了。
基础环境参照：https://cloud.tencent.com/developer/article/1806089--kubernetes集群1.20.5版本（当然了进行了小版本升级1.21了，系列笔记中有提）
https://cloud.tencent.com/developer/article/1806896--网关层的代理traefik
https://cloud.tencent.com/developer/article/1806549--存储块腾讯云cbs
all on kubernetes 是个人的原则。就在kubernetes的环境上搭建一个私有maven仓库了。
1. nexus3 on kubernetes
注： 不做特殊说明，工具类软件我都安装在kube-ops namespace命名空间下
1. 创建pv,pvc
嗯 存储用的都是腾讯云的cbs存储
[root@sh-master-01 ~]# kubectl get storageclass
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
cbs-csi com.tencent.cloud.csi.cbs Delete Immediate false 70dcat pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
namespace： kube-ops
name: sonatype-nexus
labels:
app: sonatype-nexus
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 50Gi
storageClassName: cbs-csi
selector:
matchLabels:
app: sonatype-nexuskubectl apply -f pvc.yaml
嗯 好吧cbs-csi 不支持selector的标签....将就的用吧...腾讯一直讲自己今年的开源项目是最多的，但是如kubernetes-csi-tencentcloud这样的项目，三年了吧 提交了issue也没有关闭呢也没有人回复。所以能用就行了...还是适应它吧......
kubectl delete -f pvc.yaml cat pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
namespace: kube-ops
name: sonatype-nexus
labels:
app: sonatype-nexus
spec:
accessModes:

resources:

kubectl apply -f pvc.yaml
kubectl describe pvc sonatype-nexus -n kube-ops
kubectl get pvc -n kube-ops
2、部署 Sonatype Nexus3

sonatype-nexus-5d98d78b86-nk75v 0/1 CrashLoopBackOff 6 9m5s查看报错如下：
嗯权限不够 咋整....嗯 由于pvc只能挂载单个pod,先执行：
kubectl delete -f nexus.yaml -n kube-ops然后修改nexus.yaml如下：
cat nexus.yaml

kubectl describe pods sonatype-nexus-79f85cc57c-scb9b -n kube-ops
嗯可以running了
然后获取一下用户名 密码：
3. ingress代理对外暴露应用
做一个ingress 代理？
cat ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: nexus-ingress
namespace: kube-ops
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
kubernetes.io/ingress.class: traefik
traefik.ingress.kubernetes.io/router.entrypoints: web
nginx.ingress.kubernetes.io/ssl-redirect: 'true'
spec:
rules:
- host: nexus.sainaihe.com
http:
paths:
- pathType: Prefix
path: /
backend:
service:
name: sonatype-nexus
port:
number: 8081
kubectl apply -f ingress.yaml4. 浏览器访问 nexus服务，并修改nexus初始密码：
嗯跨域了可咋整？ 我的两个主域名都泛域名强制跳转https了，短时间没有想好怎么解决....我就直接用了另外一个单独域名。不强跳可以直接访问了。同理我是不是可以加一个https的单独的设置....有时间了再试一下。先跑通一下nexus的代理应用......
http访问：
如下。第一次是要修改密码的关于初始密码的获取可以参照：1.2中获取初始密码的方式
嗯 对了呢 记得关闭匿名访问。anonymous
2. 添加一个aliyun maven代理跑一下
1. 添加一个aliyun maven 代理
打开 Repositories->Create repository->maven2(proxy) 并设置要代理的 Maven 仓库名称与地址
设置“仓库名称”与“仓库地址”。
- aliyun 仓库地址：http://maven.aliyun.com/nexus...
保存上面设置后回到仓库页面，可以看到已经添加了一个新的仓库 aliyun.
2. 设置aliyun maven优先级
打开 Repositories->maven public 并设置代理仓库优先级置顶
3. 本地maven私服仓库配置
设置 maven 的 Settings.xml 文件，按照下面配置进行设置私服地址和验证的用户名、密码。
3 .创建一个maven项目测试
1. 拉取测试
随手打开一个idea项目添加了一个
更新maven项目：
ok如下可以从个人配置的maven代理仓库更新了！
2. 推送设置
我是盗用了下程序的ava maven项目，pom.xml添加如下配置：
nexus
releases
http://http://nexus.xxx.com//repository/maven-releases/
.当然了仓库自己新建了两个：zhangpeng-releases对应release
zhangpeng-snapshots 对应snapshots
、
mvn deploy打包：
登陆nexus:
嗯对我来说这就算是成功了......
