helm3安裝neuxs3

1、環境介紹

2、安裝nexus

helm search repo nexus

helm? pull? stable/sonatype-nexus

tar? xvf? sonatype-nexus-1.21.2.tgz

helm? install? nexus? ./sonatype-nexus

kubectl? get? pod

kubectl describe pod nexus-sonatype-nexus-79b5865bbc-4lb49

從而得知在請求pvc，所以創建pv

vim??pv.yaml????#這里采用的hostpath
apiVersion:?v1
kind:?PersistentVolume
metadata:
??name:?nexus-pv
spec:
??capacity:
????storage:?10Gi
??volumeMode:?Filesystem
??accessModes:
??-??ReadWriteOnce
??persistentVolumeReclaimPolicy:?Retain
??hostPath:
????path:?/helm/nexus

mkdir??-p??/helm/nexus???#在worker節點創建相應的目錄
kubecel??apply??-f?pv.yaml

查看pod狀態

kubectl get pod

kubectl?logs?nexus-sonatype-nexus-79b5865bbc-4lb49

#會報錯，是因為容器的名字重復“nexus?nexus-proxy”
Error?from?server?(BadRequest):?a?container?name?must?be?specified?for?pod?nexus-sonatype-nexus-79b5865bbc-4lb49,?choose?one?of:?[nexus?nexus-proxy]

kubectl edit deploy nexus-sonatype-nexus? ?

修改nexus-proxy為nexus

再次查看pod狀態，還是有問題

kubectl?logs?nexus-sonatype-nexus-64c75f5786-gtvlg?

Java?HotSpot(TM)?64-Bit?Server?VM?warning:?Cannot?open?file?/nexus-data/log/jvm.log?due?to?No?such?file?or?directory
Warning:??Cannot?open?log?file:?/nexus-data/log/jvm.log
Warning:??Forcing?option?-XX:LogFile=/tmp/jvm.log
Unable?to?update?instance?pid:?Unable?to?create?directory?/nexus-data/instances
/nexus-data/log/karaf.log?(No?such?file?or?directory)
Unable?to?update?instance?pid:?Unable?to?create?directory?/nexus-data/instances

從而得知是目錄/nexus-data/instances沒有權限

kubectl get deploy nexus-sonatype-nexus -oyaml

是因為我們創建的pv沒有權限，在worker節點給與剛才創建pv的目錄777權限

chmod 777 /helm/nexus/

kubectl delete pod nexus-sonatype-nexus-64c75f5786-gtvlg?? #刪掉原來的pod

完美起來了。

kubectl get svc

然后會發現端口不通

telnet?192.18.10.12?30070

Trying?192.18.10.12...
telnet:?connect?to?address?192.18.10.12:?Connection?refused

vim /root/nexus/sonatype-nexus/values.yaml

可以看到8080并不是nexus的真正端口，而真正的端口是

所以又要修改service文件

kubectl edit svc nexus-sonatype-nexus

再訪問即可進入

用戶名是admin，密碼是admin123

完美結束！
