You can test and debug your handler implementation and image by running your API container locally.

The cortex prepare-debug command will generate a debugging configuration file named <api_name>.debug.json based on your api spec, and it will print out a corresponding docker run command that can be used to run the container locally.

For example:

cortex prepare-debug cortex.yaml iris-classifier
> docker run -p 9000:8888 \
> -e "CORTEX_VERSION=0.34.0" \
> -e "CORTEX_API_SPEC=/mnt/project/iris-classifier.debug.json" \
> -v /home/ubuntu/iris-classifier:/mnt/project \

Make a request to the api container:

curl localhost:9000 -X POST -H "Content-Type: application/json" -d @sample.json
