With configmaps:

oc create -f minio-config.yml -n camel-k-serverless
kamel run --config configmap:minio-config MinioUploader.java

Testing the Integration

You may test your deployment using cURL:

ROUTE=$(oc get routes.serving.knative.dev minio-uploader  -o jsonpath='{.status.url}' -n camel-k-serverless)

curl --request POST $ROUTE --header 'Content-Type: text/plain' --data-raw 'This is the file content.'
