Also not with the latest dockerfile image .

Also changed to new v2 format of host.json wo. success.

I've tried publishing this code 3 times to Functions and I haven't been able to hit the http trigger without getting a 404.

Are there any extra steps that should be taken other than what is in the README and the linked documentation?

It would be helpful to have dev branch with docker file consuming the latest version of worker and host.

There are important files that Microsoft projects should all have that are not present in this repository. A pull request has been opened to add the missing file(s). When the pr is merged this issue will be closed automatically.

Microsoft teams can learn more about this effort and share feedback within the open source guidance available internally.

I cloned and the example which targets base image: microsoft/azure-functions-python3.6:v2.0.11737-alpha

When I go to

http://localhost:8080/api/HttpTrigger?name=hi

I see an Http Error 406. In the docker logs I see that the HttpTrigger was hit.

info: Function.HttpTrigger[0]
      => System.Collections.Generic.Dictionary`2[System.String,System.Object] => System.Collections.Generic.Dictionary`2[System.String,System.Object]
      Executing 'Functions.HttpTrigger' (Reason='This function was programmatically called via the host APIs.', Id=f7d69d25-233a-41da-a569-95a2bdaa9ca1)

For this sample, add notes on how to pass in the values for the connection strings for each of the triggers, i.e.,:
docker run -e AzureWebJobsStorage="<connection string>"

When trying to get the admin key from /api/functions/admin/masterkey they got an error that looks like the host wasn't generating the API keys. With the latest function core tools installation, this error can be reproduced. Simple HTTP Trigger.

Everything seems fine when I access my python app on this link:
http://funcmandag.azurewebsites.net/

However, when I curl this in terminal:
curl http://funcmandag.azurewebsites.net/api/HttpTriggerJS1?name=erlend
it returns nothing. When I paste it in the browser it gives me http error code 500.

Has anyone else experienced this?

The exact same thing happens locally:
http://localhost:8080/api/HttpTriggerJS1?name=erlend

The latest Docker file that is updated with the alpha doesn’t work, it is unable to find workers path.

Running with bash via Ubuntu 16.04 subsystem for Windows.

Followed instructions here: https://github.com/Azure/azure-functions-docker-python-sample/wiki/Getting-started-using-Functions-Core-Tools.

Downloaded linux zip file from https://ci.appveyor.com/project/appsvc/azure-functions-cli/build/2.0.1.294/artifacts

Upon using binaries to run func init . --worker-runtime python (or any other call to func), I get the following errors:
Failed to load X{z�, error: libunwind.so.8: cannot open shared object file: No such file or directory
Failed to bind to CoreCLR at '/mnt/c/Users/Administrator/dev/soh-local/func_venv_bash/linux_functions/libcoreclr.so'

Fixed by running apt-get install libunwind8

Should the Dockerfile 1st line read
FROM mcr.microsoft.com/azure-functions/python:2.0

I get a docker build error with the stated docker image
manifest for microsoft/azure-functions-python3.6:v2.0.11737-alpha not found
