can be tested with

create an account at snyk.io, obtain an API key, paste your api key in ./examples/pipelines/snyk-project/pipelinerun.yaml as the value of the parameter producer-snyk-docker-api-key
then run

make dev-teardown install # cleanup
bin/cmd/draconctl pipelines deploy ./examples/pipelines/snyk-project # setup the workflow
kubectl -n dracon create -f ./examples/pipelines/snyk-project/pipelinerun.yaml

you can monitor the workflow with
kubectl -n dracon get po -w
once the consumer stdout-json finishes you can see the findings in the logs
