backend

README.md

This directory contains code for the components that comprise the Kubeflow Pipelines backend.

Building & Testing

To run all unittests for backend:

go test -v -cover ./backend/...

The API server itself can be built using:

go build -o /tmp/apiserver backend/src/apiserver/*.go

Building APIServer image locally

The API server image can be built from the root folder of the repo using:

export API_SERVER_IMAGE=api_server
docker build -f backend/Dockerfile . --tag $API_SERVER_IMAGE

Deploy APIServer with the image you own build

Run

kubectl edit deployment.v1.apps/ml-pipeline -n kubeflow

You'll see the field reference the api server docker image. Change it to point to your own build, after saving and closing the file, apiserver will restart with your change.

Building Go client library and swagger files

After making changes to proto files, the Go client libraries and swagger files need to be regenerated and checked-in. The backend/api/generate_api.sh script takes care of this. It should be noted that this requires Bazel, version 0.24.0`
