kubernetes-环境变量不适用于整数 [英] kubernetes - environment variables not works with integers

问题描述

我在 docker中运行了一个.netcore Web App。因此开始将它与kubernetes集群在一起。在appsettings.json上有四个配置，这些配置将由环境变量转换（都在 $ {}之间）：

I have one .netcore Web App running in "docker". So started to cluster it with kubernetes. Has four configs on the appsettings.json that will be converted by environment variables(all between "${}"):

   {
  "ConnectionSettings": [
    {
      "id": "${connectionSettings.connectionString.idMongoDb}",
      "databaseName": "${connectionSettings.connectionString.databaseName}",
      "connectionString": "${connectionSettings.connectionString.mongoDB}"
    }
  ],
    {
      "Key": "Token.Issuer",
      "Value": "${configuration.token.issuer}",
      "Description": "",
      "ModifiedDate": "2018-05-05 00:00:00.0000000",
      "ModifiedBy": "system",
      "AllowedProfiles": 1
    }
}

这是我的 .yaml 文件的一部分：

It's a bit of my .yaml file:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp-dev-api-dep
  labels:
    app: myapp-dev-api-dep
    tier: app
    version: v1
spec:
  selector:
    matchLabels:
      app: myapp-dev-api
      tier: app
      version: v1
  replicas: 1
  template:
    metadata:
      labels:
        app: myapp-dev-api
        tier: app
        version: v1
    spec:
      containers:
        - name: myapp-dev-api
          image: 'myappapi_tstkube:latest'
          env:
            - name: connectionSettings.connectionString.mongoDB
              value: mongodb://192.168.20.99:27017
            - name: configuration.token.issuer
              value: '86400'
          ports:
            - name: http 
              containerPort: 80
              protocol: TCP
          livenessProbe:
            initialDelaySeconds: 30
            periodSeconds: 3600
            httpGet:
              path: /swagger/index.html
              port: 80
          resources:
            requests:
              cpu: 25m
              memory: 200Mi
          terminationMessagePath: /dev/termination-log
          terminationMessagePolicy: File
          imagePullPolicy: IfNotPresent
      restartPolicy: Always
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxUnavailable: 25%
      maxSurge: 25% 

看看我的配置：

变量 connectionSettings.connectionString.mongoDB 有效。但是变量 configuration.token.issuer 不能替代应用设置。

The variable "connectionSettings.connectionString.mongoDB" works. But the variable "configuration.token.issuer" can't substituted on the appsetting.

进行了一些测试。我只是用数字变量才发现问题。

Made some tests. I found the problem only with variables of numbers.

有人有想法或您有问题吗？

Has somebody an idea or have you had the problem?

推荐答案

问题出在yamls识别码中。 yaml文件中的错误空间可能有很多问题。

The problem was in the yamls identification code. You may have many problems with the error space in the yaml file.

关于数字。两个答案都是正确的。您可以使用单引号'86400'和ACII \ x38 \ x36 \ x34 \ x30 \ x30。

About the number. Both answers are right. You can use single quotation marks '86400' and ACII "\ x38 \ x36 \ x34 \ x30 \ x30".
