1.使用命令创建chart
helm create chart名称
[root@master linux-amd64]# cd ..
[root@master ~]# helm create mychart
Creating mychart
[root@master ~]# ls
10-flannel.conflist cronjob.yaml ingress01.yaml mary recommended.yaml service1.yaml
10-kubeadm.conf deploy.yaml ingress-controller.yaml mychart redis.properties sts.yaml
admin.conf deploy.yaml.1 job.yaml myconfig.yaml secret-var.yaml
cm.yaml ds.yaml kube-flannel.yml rbac-rolebinding.yaml secret-vol.yaml
config-var.yaml helm-v3.6.0-linux-amd64.tar.gz linux-amd64 rbac-role.yaml secret.yaml
[root@master ~]# cd mychart
[root@master mychart]# ls
charts Chart.yaml templates values.yaml
[root@master mychart]# ls charts/
[root@master mychart]# cd charts/
[root@master charts]# cd ..
[root@master mychart]# cat Chart.yaml #查看信息
apiVersion: v2
name: mychart
description: A Helm chart for Kubernetes
?
# A chart can be either an ‘application‘ or a ‘library‘ chart.
#
# Application charts are a collection of templates that can be packaged into versioned archives
# to be deployed.
#
# Library charts provide useful utilities or functions for the chart developer. They‘re included as
# a dependency of application charts to inject those utilities and functions into the rendering
# pipeline. Library charts do not define any templates and therefore cannot be deployed.
type: application
?
# This is the chart version. This version number should be incremented each time you make changes
# to the chart and its templates, including the app version.
# Versions are expected to follow Semantic Versioning (https://semver.org/)
version: 0.1.0
?
# This is the version number of the application being deployed. This version number should be
# incremented each time you make changes to the application. Versions are not expected to
# follow Semantic Versioning. They should reflect the version the application is using.
# It is recommended to use it with quotes.
appVersion: "1.16.0"
[root@master mychart]# cd templates/
[root@master templates]# ls
deployment.yaml _helpers.tpl hpa.yaml ingress.yaml NOTES.txt serviceaccount.yaml service.yaml tests
[root@master templates]# rm -rf * #删除templates里面的文件，然后等下把自己写的放到这里面
[root@master templates]# ls
[root@master templates]#
?
Chartyaml: 当前chart属性配置信心
templates: 编写yaml文件放到这个目录中
values.yaml:yaml文件可以使用全局变量
2.在templates文件夹创建两个yaml文件
deployment.yaml
service.yaml
[root@master templates]# kubectl create deployment web1 --image=nginx --dry-run -o yaml > deployment.yaml
W0611 16:53:59.635980 32639 helpers.go:553] --dry-run is deprecated and can be replaced with --dry-run=client.
[root@master templates]# ls
deployment.yaml
[root@master templates]# cat deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
creationTimestamp: null
labels:
app: web1
name: web1
spec:
replicas: 1
selector:
matchLabels:
app: web1
strategy: {}
template:
metadata:
creationTimestamp: null
labels:
app: web1
spec:
containers:
- image: nginx
name: nginx
resources: {}
status: {}
[root@master templates]# kubectl create deployment web1 --image=nginx #先创建web1 ,然后再执行下面的service.yaml
deployment.apps/web1 created
[root@master templates]# kubectl get pods
[root@master templates]# kubectl expose deployment web1 --port=80 --target-port=80 --type=NodePort --dry-run -o yaml > service.yaml
W0611 16:59:07.608904 2461 helpers.go:553] --dry-run is deprecated and can be replaced with --dry-run=client.
[root@master templates]# ls
deployment.yaml service.yaml
[root@master templates]# vi service.yaml
#然后再删除web1
[root@master templates]# kubectl delete deployment web1
deployment.apps "web1" deleted
[root@master templates]# kubectl get pods
[root@master templates]# ls
deployment.yaml service.yaml
?
3.安装mychart
[root@master ~]# helm install web1 mychart/
NAME: web1
LAST DEPLOYED: Fri Jun 11 17:05:55 2021
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
[root@master ~]# kubectl get pods
web1-6fbb48567f-ch86p 1/1 Running 0 61s
root@master ~]# kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 5d20h
ui3-weave-scope NodePort 10.103.97.141 <none> 80:31674/TCP 53m
web NodePort 10.111.111.127 <none> 80:32079/TCP 20h
web1 NodePort 10.96.150.188 <none> 80:31544/TCP 79s
?
4.应用升级
helm upgrade chart名称
[root@master ~]# helm upgrade web1 mychart/
Release "web1" has been upgraded. Happy Helming!
NAME: web1
LAST DEPLOYED: Fri Jun 11 17:12:01 2021
NAMESPACE: default
STATUS: deployed
REVISION: 2
TEST SUITE: None
?
通过传递参数，动态渲染模板，yaml内容动态传入参数生成
在chart中有values.yaml文件，定义yaml文件全局变量
[root@master mychart]# ls
charts Chart.yaml templates values.yaml
[root@master mychart]#
?
1.在values.yaml定义变量和值
2.在具体yaml文件中，获取定义变量值
yaml文件大体有几个地方不同
image
tag
label
port
replicas
一、在values.yaml定义变量和值
这个是原本文件里面的内容
# Default values for mychart.
# This is a YAML-formatted file.
# Declare variables to be passed into your templates.
?
replicaCount: 1
?
image:
repository: nginx
pullPolicy: IfNotPresent
# Overrides the image tag whose default is the chart appVersion.
tag: ""
?
imagePullSecrets: []
nameOverride: ""
fullnameOverride: ""
?
serviceAccount:
# Specifies whether a service account should be created
create: true
# Annotations to add to the service account
annotations: {}
# The name of the service account to use.
# If not set and create is true, a name is generated using the fullname template
name: ""
?
podAnnotations: {}
?
podSecurityContext: {}
# fsGroup: 2000
?
securityContext: {}
# capabilities:
# drop:
# - ALL
# readOnlyRootFilesystem: true
# runAsNonRoot: true
# runAsUser: 1000
?
service:
type: ClusterIP
port: 80
?
ingress:
enabled: false
className: ""
annotations: {}
# kubernetes.io/ingress.class: nginx
# kubernetes.io/tls-acme: "true"
hosts:
- host: chart-example.local
paths:
- path: /
?
[root@master mychart]# vim values.yaml
?
二、在templates的yaml文件中使用values.yaml定义的变量
通过表达式形式使用全局变量
{{.Values.变量名称}}
{{.Release.Name}}
[root@master mychart]# cd templates/
[root@master templates]# ls
deployment.yaml service.yaml
[root@master templates]# vim deployment.yaml
[root@master templates]# vim service.yaml
?
[root@master ~]# helm install --dry-run web2 mychart/
