[root@server4 kubeapps]# vim values.yaml 

11   imageRegistry: "reg.westos.org"
51   enabled: true
57   hostname: kubeapps.westos.org

[root@server4 kubeapps]# cd charts/
[root@server4 charts]# ls
common  postgresql
[root@server4 charts]# cd postgresql/
[root@server4 postgresql]# ls
Chart.lock  Chart.yaml  files      templates           values.yaml

三、安装部署

[root@server4 kubeapps]# ls
Chart.lock  charts  Chart.yaml  crds  README.md  templates  values.schema.json  values.yaml
[root@server4 kubeapps]# kubectl create namespace kubeapps
namespace/kubeapps created
[root@server4 kubeapps]# helm install kubeapps . -n kubeapps

[root@server4 kubeapps]# kubectl -n kubeapps get pod

[root@server4 kubeapps]# kubectl -n kubeapps get svc
[root@server4 kubeapps]# kubectl -n kubeapps get ingress
NAME       CLASS    HOSTS                 ADDRESS       PORTS   AGE

[root@server4 kubeapps]# kubectl -n kubeapps describe ingress kubeapps 

1.真机解析

[root@server4 kubeapps]# kubectl -n ingress-nginx  get svc
