I am also encountering the same issue. The dockerfile image I am using is: microsoft/azure-functions-python3.6:v2.0.11961-alpha

I made it work.
You first need to update the host.json to:

{
"version": "2.0",
"healthMonitor": {
"enabled": true,
"healthCheckInterval": "00:00:10",
"healthCheckWindow": "00:02:00",
"healthCheckThreshold": 6,
"counterThreshold": 0.80
},
"functionTimeout": "00:05:00",
"logging": {
"fileLoggingMode": "debugOnly"
},
"extensions": {
"http": {
"routePrefix": "api",
"maxConcurrentRequests": 5,
"maxOutstandingRequests": 30
},
"queues": {
"visibilityTimeout": "00:00:10"
},
"eventHubs": {
"batchCheckpointFrequency": 1,
"eventProcessorOptions": {
"maxBatchSize": 1000,
"prefetchCount": 1000
}
}
},
"swagger": {
"enabled": true
}
}

This is my Dockerfile:

FROM microsoft/azure-functions-python3.6:2.0.12121

ENV host:logger:consoleLoggingMode=always

COPY . /home/site/wwwroot

RUN cd /home/site/wwwroot && pip install -r requirements.txt

The I issued docker build and pushed the image to an azure registry.

Then using the portal add a Function App of type Linux Preview Docker (the az commands did not work for me however the deployment via portal). For the container image choose the one previously pushed.

Finally issue these 2 commands that configure parameters of the app:

storageConnectionString=$(az storage account show-connection-string --resource-group XXXX --name YYYYYY --query connectionString --output tsv)

az functionapp config appsettings set --name ZZZZZZ --resource-group XXXXX --settings AzureWebJobsDashboard=$storageConnectionString AzureWebJobsStorage=$storageConnectionString
