Kubernetes operator for Bagua jobs

This repository implements a kubernetes operator for Bagua distributed training job which supports static and elastic workloads. See CRD definition.

Prerequisites

  • Kubernetes
  • kubectl

Installation

Run the operator locally

git clone https://github.com/BaguaSys/operator.git
cd operator

# install crd
kubectl apply -f config/crd/bases/bagua.kuaishou.com_baguas.yaml

Deploy the operator

Install Bagua on an existing Kubernetes cluster.
