Kubernetes 使用单舵图部署多个军种

我是赫尔姆和库伯内特斯的新手。

我目前的要求是使用通用舵图设置多个服务

下面是一个场景

我对所有服务都有一个共同的docker映像

对于每个服务，都有不同的命令要运行总共有40多种服务。

范例

我掌握的舵图的当前状态是

demo-helm
|- Chart.yaml
|- templates
   |- deployment.yaml
   |- _helpers.tpl
|- values
   |- values-serviceA.yaml
   |- values-serviceB.yaml
   |- values-serviceC.yaml
    and so on ...

现在，因为我想使用相同的掌舵图并部署多个服务。我该怎么做

我使用了以下命令

helm安装demo-helm-f values/values-serviceA.yaml-f values-serviceB.yaml

，但它只对末尾提供的值文件进行部署

这是我的

deployment.yaml

文件

apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ include "helm.fullname" . }}
  labels:
    {{- include "helm.labels" . | nindent 4 }}
spec:
  replicas: {{ .Values.replicaCount }}
  selector:
    matchLabels:
      {{- include "helm.selectorLabels" . | nindent 6 }}
  template:
    metadata:
    {{- with .Values.podAnnotations }}
      annotations:
        {{- toYaml . | nindent 8 }}
    {{- end }}
      labels:
        {{- include "helm.selectorLabels" . | nindent 8 }}
    spec:
      {{- with .Values.imagePullSecrets }}
      imagePullSecrets:
        {{- toYaml . | nindent 8 }}
      {{- end }}
      containers:
        - name: {{ .Chart.Name }}
          image: "{{ .Values.image.repository }}:{{ .Values.image.tag | default .Chart.AppVersion }}"
          imagePullPolicy: {{ .Values.image.pullPolicy }}
          command: {{- toYaml .Values.command |nindent 12}} 
          resources:
            {{- toYaml .Values.resources | nindent 12 }}
          volumeMounts:
            - name: secrets
              mountPath: "/usr/src/app/config.ini"
              subPath: config.ini
      {{- with .Values.nodeSelector }}
      nodeSelector:
        {{- toYaml . | nindent 8 }}
      {{- end }}
      {{- with .Values.affinity }}
      affinity:
        {{- toYaml . | nindent 8 }}
      {{- end }}
      {{- with .Values.tolerations }}
      tolerations:
        {{- toYaml . | nindent 8 }}
      {{- end }}
      volumes:
        - name: secrets
          secret:
            secretName: sample-application
            defaultMode: 0400

更新。

由于我的需求已经更新，可以在一个文件中添加服务的所有值，所以我可以通过以下方式来完成

deployment.yaml

      containers:
        - name: {{ $service }}

          imagePullPolicy: IfNotPresent
          command: {{- toYaml .command |nindent 12}}
          resources:

当您这样做时，serviceB值将覆盖serviceA值。您需要使用不同的发布名称单独运行该命令，如下所示：

helm install demo-helm-A . -f values/values-serviceA.yaml
helm install demo-helm-B . -f values/values-serviceB.yaml

---

有没有其他方法像我在一个循环中运行自 每个my values.yaml文件的唯一区别是命令部分。 因此，我可以在同一个文件中包含命令，如下>命令：>- [“bash”、“-c”、“python serviceA.py”]>-[“bash”、“-c”、“python serviceB.py“]>-[“bash”、“-c”、“python serviceC.py”]–whoami 20 几小时前

是的，您可以编写一个相当简单的bash脚本，它将在一个循环中运行所有内容：

for i in {A..Z}; do sed "s/{{COMMAND}}/[\"bash\", \"-c\", \"python service$i.py\"]/g" values/values-service-template.yaml | helm install demo-helm-$i . -f - ; done

在

values/values服务模板.yaml

文件中，只需放置

command:{{{command}}

，而不是

command:[“bash”、“-c”、“python serviceAregion1.py”]

，因为在循环的每次迭代中，它都会被确切的命令替换

至于

{A..Z}

把你需要的东西放在那里。如果您只有从

A

到

K

命名的服务，或者如果您喜欢数字值而不是字母，则可能是

{A..K}

以下

sed

命令将用实际命令替换原始

values/values服务模板.yaml

中的

{{command}

片段，例如

[“bash”、“-c”、“python serviceA.py”]

、

[“bash”、“-c”、“python serviceB.py”]

等等

sed "s/{{COMMAND}}/[\"bash\", \"-c\", \"python service$i.py\"]/g" values/values-service-template.yaml

然后它将通过管道（

|

符号）传输到：

---

其中，

demo-helm-$i

将被扩展，例如扩展到

demo-helm-A

，但这里的关键元素是

-

字符，这意味着：从标准输入读取，而不是从文件读取，这通常在

-f

标志之后出现。

是否有其他方法像我在循环中运行所有东西一样，因为我的每个

值的唯一区别。yaml

文件是命令部分。因此，我可以在同一个文件中包含如下命令：>-[“bash”、“-c”、“python serviceA.py”]>-[“bash”、“-c”、“python serviceB.py”]>-[“bash”、“-c”、“python serviceC.py”]谢谢您的帮助。但是由于我的要求现在有了一些变化，我更新了这个问题。
