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 using Remote Build Execution

If you are a dev in the Kubeflow Pipelines team, you can use Remote Build Execution Service to build the API Server image using Bazel with use of a shared cache for speeding up the build. To do so, execute the following command:

./build_api_server.sh -i gcr.io/cloud-ml-pipelines-test/api-server:dev

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

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`

Updating python dependencies

pip-tools is used to manage python dependencies. To update dependencies, edit requirements.in and run ./update_requirements.sh <requirements.in >requirements.txt to update and pin the transitive dependencies.
