Sample Function Python

Run on OpenFunction

1. Install OpenFunction
2. Refer to the go function sample

Run it locally

Build the function locally

pack build python-sample --builder openfunction/gcp-builder:v1 --env GOOGLE_FUNCTION_TARGET=hello_world

The builder image used above may not be suitable for the MacOS m2 chip (Arm) architecture. For solutions, please refer to Dockerfile and then you can use the newly built builder image like:

pack build python-sample --builder <your dockerhub account>/openfunction-gcp-builder:v1 --env GOOGLE_FUNCTION_TARGET=hello_world

If it is just for research use, you can also use the image created by @ToviHe hetovi1997/openfunction-gcp-builder:v1

Run the function

docker run --rm --env="FUNC_CONTEXT={\"name\":\"python-sample\",\"version\":\"v1.0.0\",\"port\":\"8080\",\"runtime\":\"Knative\"}" --env="CONTEXT_MODE=self-host" --name python-sample -p 8080:8080 python-sample

Send a request

curl http://localhost:8080
# hello, world
