sls with runtime Docker, fails to invoke

[karanrk]

Hello Team,

I tried deploying a serverless application that is completed built with personal docker image (dockerhub) and the deployment is successful but the invoke isn't. The deployment and invoke works fine on the ibmcloud without serverless, but looking at your examples on docker this is something that should have worked. I don't see any logs generated too.

@karanrk Sorry you are having issues. Can you post the serverless.yaml configuration file you are using to deploy the service?

[karanrk]

Below is my serverless.yml file

service: "MyServiceName"

provider:
  name: openwhisk

  runtime: python

functions:
  "MyfunctionName":
    handler: krkamatg/chatter-uc
    runtime: docker
    timeout: 600
    memory: 2048

plugins:
  - serverless-openwhisk

Below is my Dockerfile

FROM openwhisk/python3action

COPY requirements.txt ./

COPY download-toolkit.py ./

ENV https_proxy "MyProxy"
ENV http_proxy "MyProxy"

RUN export http_proxy="MyProxy" && export https_proxy="MyProxy" && \
pip install --no-cache-dir -r requirements.txt

RUN export http_proxy="MyProxy" && export https_proxy="MyProxy" && python3 download-toolkit.py

COPY unitConvertion.py ./

CMD [ "python3", "unitConvertion.py" ]

I have managed to get this working based on the files above. The Docker image being built is incorrect and should not include or attempt to run the unitConvertion.py file as the start command.

• Use the following Dockerfile to build a new image

FROM openwhisk/python3action

COPY requirements.txt ./

COPY download-toolkit.py ./

ENV https_proxy "MyProxy"
ENV http_proxy "MyProxy"

RUN export http_proxy="MyProxy" && export https_proxy="MyProxy" && \
pip install --no-cache-dir -r requirements.txt

RUN export http_proxy="MyProxy" && export https_proxy="MyProxy" && python3 download-toolkit.py

• Push this image to Docker Hub as <DOCKERHUB_USER>/openwhisk_python
• Use the following serverless.yaml to define a custom Python runtime for your function.

service: unit-conversion

provider:
  name: openwhisk
  runtime: python

functions:
  test:
    handler: unitConvertion.main
    image: <DOCKERHUB_USER>/openwhisk_python

plugins:
  - serverless-openwhisk

When I follow these steps the code executes with the following output...

$ sls invoke -f test
{
    "0 celsius to fahrenheit": "32.00000039999997",
    "How many meters are in a kilometer?": "1000.0",
    "How many meters are in one inch": "0.0254",
    "one hour is how many minutes ?": "60.0"
}

$ sls logs -f test

@karanrk I'm going to close this as this looks like it was a configuration error rather than a bug in the framework.

Let me know if you are still having issues....
