Question

我的架构中有多个.NET微服务，每个我都创建了一个部署对象，现在我尝试部署到运行kubernetes的Azure容器服务。当我运行kubectl apply -f services.yml时，我总是有一些失败的pod。但如果我单独运行这些部署，那么它们都可以工作。我总结的错误是：无法启动容器，系统找不到指定的文件。 pods状态显示为：CrashLoopBackOff

我的服务文件如下所示：

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: service1-deployment
  labels:
    app: service1
spec:
  replicas: 1
  selector:
    matchLabels:
      app: service1
  template:
    metadata:
      labels:
        app: service1
    spec:
      containers:
      - name: service1
        image: iolregistry.azurecr.io/panviva/doc:v1
        command: ["service1.exe"]
      imagePullSecrets:
      - name: regsecret
---
apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: service2-deployment
  labels:
    app: service2
spec:
  replicas: 1
  selector:
    matchLabels:
      app: service2
  template:
    metadata:
      labels:
        app: service2
    spec:
      containers:
      - name: service2
        image: iolregistry.azurecr.io/panviva/doc:v1
        command: ["service2.exe"]
      imagePullSecrets:
      - name: regsecret

实际上我在文件中有更多的部署，但你得到了想法。我已经尝试将这些部署分成不同的文件并调用kubectl apply -f service1.yml -f service2.yml但我仍然收到相同的错误。我相信它与kubernetes同时启动多个pod有关。我该如何解决这个问题？

编辑：描述失败的pod会产生以下结果：

如何在Kubernetes集群中同时部署多个部署？
