使用前请编写 release.values.yaml 文件

1. 设置拉取镜像 name 与 tag

image:
  repository: registory/namespace/name
  pullPolicy: IfNotPresent
  tag: "latest"

2. 设置拉取镜像凭证

imageCredentials:
  registry: registry.cn-hangzhou.aliyuncs.com
  username: deploy-man@skylark
  password: changeit

3. 设置 application hosts(支持域名和IP)

applicationHosts:
  - example.com
  - 192.168.0.1

4. 设置反向代理对应 path 规则

appIngressroutes:
  - name: example-name
    path: /example-path
    servicePortName: 0

5. 设置外部服务代理规则

externalIngressroute:
  - name: "external-name"
    # 外部服务是域名则用 host
    host: "external-host"
    # 外部服务是 ip 则用 ip
    ip: "192.168.0.1"
    port: "443"
    path: "/external-path"
    # 映入外部服务所需要添加的中间件
    middlewares:
      - cors-header

注： 外部服务所用中间件 cors-header 目的是给前端调用第三方服务时使用

6. 设置应用需要的 env 参数

env: {}

7. 应用需要使用 https 时设置

使用证书挑战设置 certResolver 参数

applicationTLS:
  certResolver: jet

使用自有证书设置 TLSSecret

applicationTLS:
  TLSSecret:
    certificate: certificate-file base64 encoding
    key: key-file base64 encoding

8. 设置已存在的 secret 资源作为环境变量

envFromSecrets:
  - existSecretName: "jet-env-secret"
    env:
      - envName: "LOG_LEVEL"
        secretKey: "jet_plugin_level"

secret内容如下：

apiVersion: v1
kind: Secret
metadata:
  name: example-env-secret
type: Opaque
  data:
  example-key1: TnV6YUNYQTlZUUxMOWI= # base64 encoding string
  example-key2: aYnlwd1VpcFNlb1FIMVR # base64 encoding string

Misc

应用启动初始化设置

initContainers:
  - name: init
    image: busybox:latest
    command: ["sh", "-c"]
    args: []
    envFrom:
       - configMapRef:
           name: {{ include "application-chart-template.name" $ }}-env

image command 覆盖

command:
  - /bin/sh
  - -c

应用文件挂载设置

volumeMounts:
  - mountPath: /path/file
    name: volumeName

volumes:
  - name: volumeName
    hostPath:
      path: /local/path
      type: DirectoryOrCreate

应用跨域设置

corsSettings:
  accessControlAllowHeaders:
    - '*'
  accessControlAllowMethods:
    - GET
    - OPTIONS
    - PUT
  accessControlAllowOriginList:
    - '*'
  accessControlMaxAge: "100"

调度设置

• nodeSelector

nodeSelector:
  key: value

• tolerations

tolerations:
  - key: "key1"
    operator: "Equal"
    value: "value1"
    effect: "NoSchedule"
  - key: "key1"
    operator: "Equal"
    value: "value1"
    effect: "NoExecute"

参数说明

• affinity

affinity:
  nodeAffinity:
    requiredDuringSchedulingIgnoredDuringExecution:
      nodeSelectorTerms:
      - matchExpressions:
        - key: kubernetes.io/os
          operator: In
          values:
          - linux
    preferredDuringSchedulingIgnoredDuringExecution:
    - weight: 1
      preference:
        matchExpressions:
        - key: label-1
          operator: In
          values:
          - key-1
    - weight: 50
      preference:
