1、Helm Chart 目录结构
mychart/
├── Chart.yaml # 存放该Chart的基本信息
├── values.yaml # 存放参数值
├── charts/ # 存放该Chart依赖的其他子Chart
├── templates/ # 存放模板文件
│ ├── deployment.yaml # 资源模板
│ ├── service.yaml # 资源模板
│ ├── ingress.yaml # 资源模板
│ ├── _helpers.tpl # 存放自定义模板
│ └── NOTES.txt # 安装完成后在终端显示的提示信息
├── crds/ # 自定义资源模板
└── .helmignore # 指定哪些文件在打包Chart (helm package)时应被忽略2、templates的基本使用
[root@master-11 mychart]# mkdir templates
[root@master-11 mychart]# touch Chart.yaml
[root@master-11 mychart]# touch values.yaml
[root@master-11 mychart]# tree .
.
├── Chart.yaml
├── templates
│ └── deployment.yaml
└── values.yaml# 再找一个nginx的deployment的创建文件
[root@master-11 mychart]# cat ./templates/deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:creationTimestamp: nulllabels:app: nginxname: nginx
spec:replicas: 1selector:matchLabels:app: nginxtemplate:metadata:labels:app: nginxspec:containers:- image: registry.cn-beijing.aliyuncs.com/xwk123/nginx:aaaname: nginx# 尝试安装
[root@master-11 mychart]# helm install nginx .
NAME: nginx
LAST DEPLOYED: Thu Oct 2 00:14:30 2025

[root@master-11 mychart]# kubectl get pods
NAME READY STATUS RESTARTS AGE

[root@master-11 mychart]# helm uninstall nginx
release "nginx" uninstalled
3、Chart.yaml 与 values.yaml
# 先随便写一个Chart.yaml
[root@master-11 mychart]# cat Chart.yaml
apiVersion: v2
name: mychart
description: nginx
type: application
version: 0.1.0
appVersion: "1.0.0"# 编写values.yaml文件，将deployment中的变量全部写到values.yaml里面
[root@master-11 mychart]# cat values.yaml
replicas: 1
image:repository: registry.cn-beijing.aliyuncs.com/xwk123/nginxtag: aaa# 编写deployment文件，将里面的变量全部替换掉
[root@master-11 mychart]# cat ./templates/deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:creationTimestamp: nulllabels:app: {{ .Chart.Name }} # .Chart.Name指的就是Chart.yaml文件里的name字段后对应的值mychartname: {{ .Chart.Name }}
spec:replicas: {{ .Values.replicas }} # .Values.replicas指的就是values.yaml文件中replicas字段后对应的值1selector:matchLabels:app: {{ .Chart.Name }}template:metadata:labels:app: {{ .Chart.Name }}spec:containers:- image: "{{ .Values.image.repository }}:{{ .Values.image.tag }}" # .Values.image.repository指的就是values.yaml文件中image字段下的tag所对应的值，和上面的差别就是多了一层image字段，使用方法还是一样的，这种组合需要添加双引号name: nginx# 查看渲染效果
[root@master-11 mychart]# helm template nginx .
