容器化逻辑应用在部署到 AKS 时无法正常工作

Question

We are trying to deploy a logic app as containerized workload in AKS. Following is our Docker file:

FROM mcr.microsoft.com/azure-functions/dotnet:3.0.14492-appservice

ENV AzureWebJobsStorage=<StorageAccount connection string>
ENV AZURE_FUNCTIONS_ENVIRONMENT Development
ENV AzureWebJobsScriptRoot=/home/site/wwwroot
ENV AzureFunctionsJobHost__Logging__Console__IsEnabled=true
ENV FUNCTIONS_V2_COMPATIBILITY_MODE=true

COPY ./bin/release/netcoreapp3.1/publish/ /home/site/wwwroot

Following is our deployment manifest file:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: pfna-pgt-sf-pdfextract
  namespace: canary
  labels:
    app: pfna-pgt-sf-pdfextract

      containers:

          image: "image_link"
          resources:
            requests:

            limits:

              memory: 256Mi
          ports:
            - containerPort: 80
          env:
            - name: AzureBlob_connectionString
              value: <connection_string>
            - name: AzureWebJobsStorage
              value: <connection_string>
      imagePullSecrets:

Following is connections.json:

{
  "serviceProviderConnections": {
    "AzureBlob": {
      "parameterValues": {
        "connectionString": "@appsetting('AzureWebJobsStorage')"
      },
      "serviceProvider": {
        "id": "/serviceProviders/AzureBlob"
      },
      "displayName": "localAzureBlob"
    }
  },
  "managedApiConnections": {}
}

Following is the host.json:

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  },
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle.Workflows",
    "version": "[1.*, 2.0.0)"
  },
  "extensions": {
    "workflow": {
       "settings": {
          "Runtime.Backend.VariableOperation.MaximumStatelessVariableSize": "5000000"
       }
    }
 }
}

The image is running successfully in docker desktop but when deployed to AKS we are getting 'Function host is not running'.

Please help resolve this.

You need to specify WEBSITE_HOSTNAME as well (doesn't matter what it is, just needs to be specified)

That being said, as of today there is another issue that is causing the function host to not start (libadvapi32.dll).
