一、Helm开发与实践

1、Helm Chart详解

1.1 Chart 目录结果

1.2 Chart.yaml 文件

# cat Chart.yaml 
apiVersion: v2
name: nginx
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"

1.3 Chart 管理依赖（dependencies）

当前chart依赖的其他chart会在dependencies字段定义为一个列表

dependencies：
  - name: apache
    version: 1.2.3
    repositort: https://example.com/charts
  - name: mysql
    version: 3.2.1
    repositort: https://another.example/charts

name: chart的名称
version：chart的版本
repository：chat 仓库的完整URL。必须使用helm repo add在本地添加仓库，也可以使用仓库的名称代替URL

2、Helm开放实践

基于Helm开放一个常规应用的步骤及YAML文件

2.1 安装Helm

参考官网安装Helm

2.2 创建Helm chart

执行以下命令创建一个新的Helm chart

# helm create app
Creating app

myapp 是chart的名称，可根据需要进行修改

2.3 编辑values.yaml 文件

进入chart目录，编辑values文件，修改配置项，如应用名称、端口号、镜像名称等

# cat values.yaml 
# Default values for app.
# This is a YAML-formatted file.
# Declare variables to be passed into your templates.

replicaCount: 1
appName: myapp

image:
  repository: nginx
  pullPolicy: IfNotPresent
  # Overrides the image tag whose default is the chart appVersion.
  tag: "1.25.2"

db:
  host: "192.168.239.128"
  port: "3306"
  user: "root"
  password: "aa123456"

containerPort: 8080
servicePort: 8080

2.4 编辑deployment.yaml 文件

编辑templates/deployment.yaml文件，定义应用的Deployment。

# cat templates/deployment.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ .Values.appName }}-deployment
spec:
  replicas: {{ .Values.replicaCount }}
  selector:
    matchLabels:
      app: {{ .Values.appName }}
  template:
    metadata:
      labels:
        app: {{ .Values.appName }}
    spec:
      containers:
        - name: {{ .Values.appName }}
          image: {{ .Values.image.repository }}:{{ .Values.image.tag }}
          ports:
            - containerPort: {{ .Values.containerPort }}
          env:
            - name: DB_HOST
              value: {{ .Values.db.host }}
            - name: DB_PORT
              value: "{{ .Values.db.port }}"
            - name: DB_USER
              value: {{ .Values.db.user }}
            - name: DB_PASSWORD
              value: {{ .Values.db.password }}

定义Deployment 使用了values.yaml

文件中定义的配置项。其中，replicas表示副本数，selector表示选择器，template表示Pod模版，containers表示容器列表，env表示环境变量

编辑service.yaml文件

# cat templates/service.yaml 
apiVersion: v1
kind: Service
metadata:
  name: {{ .Values.appName }}
spec:
  ports:
    - port: {{ .Values.servicePort }}
      targetPort: {{ .Values.containerPort }}
      protocol: TCP
      name: http
  selector:
    app: {{ .Values.appName }}
  type: LoadBalancer

定义一个Service，使用values.yaml 文件中定义的配置项。其中selector表示选择器，ports表示端口映射，type表示Service类型。

打包Helm chart

执行以下命令将Helm chart 打包

# helm package app/
Successfully packaged chart and saved it to: /root/Helm/app-0.1.0.tgz

部署Helm chart

执行以下命令部署Helm chart

# helm install myapp --dry-run app

          env:
            - name: DB_HOST
              value: 192.168.239.128
            - name: DB_PORT
              value: "3306"
            - name: DB_USER
              value: root
            - name: DB_PASSWORD
              value: aa123456

NOTES:
hank you for installing app.

Your release is named myapp.

To learn more about the release, try:

  $ helm status myapp
  $ helm get all myapp

# helm  list
NAME 	NAMESPACE	REVISION	UPDATED                               	STATUS  	CHART    	APP VERSION
myapp	default  	1       	2023-12-01 15:53:03.33850538 +0800 CST	deployed	app-0.1.0

其中，myapp是部署的名称，可以根据需要进行修改

以上就是基于Helm开发一个常规应用的步骤及所用到的YAML文件。

二、基于Helm的方式运维管理应用

1、基于helm 安装WordPress

1.1 方式一

1、添加WordPress chart 仓库

执行以下命令添加WordPress chart 仓库

# helm repo add bitnami https://charts.bitnami.com/bitnami
"bitnami" has been added to your repositories

创建一个名为wordpress的命名空间

# kubectl  create namespace wordpress
namespace/wordpress created

2、创建values.yaml 文件

在本地创建一个values.yaml文件，用于WordPress的相关参数。

# cat values.yaml 
# WordPress相关配置
wordpressUsername: admin
wordpressPassword: a123456
wordpressEmail: [email protected]
wordpressBlogName: k8syyds Blog

# Service相关配置
service:
  type: NodePort
  port: 80
  nodePorts:
    http: "32088"

# MySQL相关配置
mysql:
  image:
    repository: bitnami/mysql
    tag: 8.0.26-debian-10-r0
    pullPolicy: IfNotPresent
  user: wordpress
  database: wordpress
  port: 3306
  persistence:
    enabled: true
    size: 8Gi
    storageClass: "nfs-storageclass"

# WordPress相关配置
wordpress:
  image:
    repository: bitnami/wordpress
    tag: 5.8.1-debian-10-r0
    pullPolicy: IfNotPresent
  replicaCount: 1
  persistence:
    enabled: true
    size: 8Gi
    storageClass: "nfs-storageclass"

3、安装WordPress

执行以下命令安装WordPress

# helm install k8swordpress1 bitnami/wordpress -f values.yaml
NAME: k8swordpress1
LAST DEPLOYED: Sat Dec  2 09:56:17 2023
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
CHART NAME: wordpress
CHART VERSION: 18.1.11
APP VERSION: 6.4.1

** Please be patient while the chart is being deployed **

Your WordPress site can be accessed through the following DNS name from within your cluster:

    k8swordpress1.default.svc.cluster.local (port 80)

To access your WordPress site from outside the cluster follow the steps below:

1. Get the WordPress URL by running these commands:

   export NODE_PORT=$(kubectl get --namespace default -o jsonpath="{.spec.ports[0].nodePort}" services k8swordpress1)
   export NODE_IP=$(kubectl get nodes --namespace default -o jsonpath="{.items[0].status.addresses[0].address}")
   echo "WordPress URL: http://$NODE_IP:$NODE_PORT/"
   echo "WordPress Admin URL: http://$NODE_IP:$NODE_PORT/admin"

2. Open a browser and access WordPress using the obtained URL.

3. Login with the following credentials below to see your blog:

  echo Username: admin
  echo Password: $(kubectl get secret --namespace default k8swordpress1 -o jsonpath="{.data.wordpress-password}" | base64 -d)

其中，mywordpress01 是安装的WordPress的名称，bitnami/wordpress 是Helm官方提供的WordPress Chart，-f values.yaml 指定使用上一步创建的values.yaml 文件，-n wordpress 指定安装的命名空间位wordpress

4、查看安装状态

执行以下命令查看安装状态

# kubectl get pods,services,pvc |grep k8s
pod/k8swordpress1-75d9749c9b-rvbdr   1/1     Running   0             2m35s
pod/k8swordpress1-mariadb-0          1/1     Running   0             2m35s
service/k8swordpress1           NodePort    10.100.27.218   <none>        80:32088/TCP,443:32110/TCP   2m35s
service/k8swordpress1-mariadb   ClusterIP   10.102.94.255   <none>        3306/TCP                     2m35s
persistentvolumeclaim/data-k8swordpress1-mariadb-0                  Bound    pvc-a8967458-9ebe-493d-b7c7-1f3aa4f82024   8Gi        RWO            rook-ceph-block    2m35s
persistentvolumeclaim/k8swordpress1                                 Bound    pvc-0d39ae1c-0ab7-4ad7-bde8-4ad17d633e45   10Gi       RWO            rook-ceph-block    2m35s

5、升级WordPress

helm upgrade mywordpress01 bitnami/wordpress -f values.yaml

删除wordpress

helm uninstall mywordpress01

6、访问WordPress

[root@master-1-230 3]# echo "WordPress URL: http://$(kubectl get svc k8swordpress1 -o jsonpath='{.status.loadBalancer.ingress[0].ip}')"
WordPress URL: http://
[root@master-1-230 3]# export NODE_PORT=$(kubectl get --namespace default -o jsonpath="{.spec.ports[0].nodePort}" services k8swordpress1)
[root@master-1-230 3]#    export NODE_IP=$(kubectl get nodes --namespace default -o jsonpath="{.items[0].status.addresses[0].address}")
[root@master-1-230 3]#    echo "WordPress URL: http://$NODE_IP:$NODE_PORT/"
WordPress URL: http://192.168.1.230:32088/
[root@master-1-230 3]#    echo "WordPress Admin URL: http://$NODE_IP:$NODE_PORT/admin"
WordPress Admin URL: http://192.168.1.230:32088/admin

[root@master-1-230 3]# echo Username: admin
Username: admin
[root@master-1-230 3]#   echo Password: $(kubectl get secret --namespace default k8swordpress1 -o jsonpath="{.data.wordpress-password}" | base64 -d)
Password: a123456

1.2 方式二

以下基于Helm的WordPress chart 包的示例

下载WordPress chart

执行以下命令将WordPress chart 下载到本地

 helm fetch bitnami/wordpress

解压WordPress chart

# tar zxvf wordpress-18.1.20.tgz

修改values.yaml 文件

在wordpress目录下，修改values.yaml文件

NOTES:
CHART NAME: wordpress
CHART VERSION: 18.1.20
APP VERSION: 6.4.1

** Please be patient while the chart is being deployed **

Your WordPress site can be accessed through the following DNS name from within your cluster:

    mywordpress.default.svc.cluster.local (port 80)

To access your WordPress site from outside the cluster follow the steps below:

1. Get the WordPress URL by running these commands:

  NOTE: It may take a few minutes for the LoadBalancer IP to be available.
        Watch the status with: 'kubectl get svc --namespace default -w mywordpress'

   export SERVICE_IP=$(kubectl get svc --namespace default mywordpress --template "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}")
   echo "WordPress URL: http://$SERVICE_IP/"
   echo "WordPress Admin URL: http://$SERVICE_IP/admin"

2. Open a browser and access WordPress using the obtained URL.

3. Login with the following credentials below to see your blog:

  echo Username: user
  echo Password: $(kubectl get secret --namespace default mywordpress -o jsonpath="{.data.wordpress-password}" | base64 -d)
您在 /var/spool/mail/root 中有新邮件

这个命令会使用values.yaml文件中定义的配置参数，安装一个名为mywordpress的新Chart实例
