helm3 自定义char之helm仓库搭建

创建一个demon

 helm create test01

tree test01/
test01/
|-- charts
|-- Chart.yaml
|-- templates
|   |-- deployment.yaml
|   |-- _helpers.tpl
|   |-- hpa.yaml
|   |-- ingress.yaml
|   |-- NOTES.txt
|   |-- serviceaccount.yaml
|   |-- service.yaml
|   `-- tests
|       `-- test-connection.yaml
`-- values.yaml

• 删除 templates里的所有文件

[root@jenkins test01]# cd templates/
[root@jenkins templates]# ls
deployment.yaml  _helpers.tpl  hpa.yaml  ingress.yaml  NOTES.txt  serviceaccount.yaml  service.yaml  tests
[root@jenkins templates]# rm -rf *
[root@jenkins templates]# ll
total 0

• 尝试运行或者直接把编辑好的yaml文件放置 templates目录里

[root@jenkins templates]# kubectl create deployment web1 --image=nginx:alpine --dry-run -o yaml > deployment.yaml
W0527 00:12:25.437455   24829 helpers.go:553] --dry-run is deprecated and can be replaced with --dry-run=client.

需要创建才能使用以下命令
kubectl create deployment web1 --image=nginx:alpine
kubectl expose deployment web1 --port=80 --target-port=80 --type=NodePort --dry-run -o yaml > service.yaml

• 最后语法检测

[root@node101 ~]# helm  lint test01/
==> Linting test01/
[INFO] Chart.yaml: icon is recommended

1 chart(s) linted, 0 chart(s) failed

• 安装

[root@jenkins helm]# helm install web1 test01/
