Volcano source comes with its own go client so setup VSCode to build Volcano

- must install go 1.12

ubuntu@WSLBOX:~/go/src/github.com/volcano-sh$ go get golang.org/dl/go1.12
ubuntu@WSLBOX:~/go/src/github.com/volcano-sh$ go1.12

Use clientset and create jobs programmatically

the project has 2 versioned client sets alpha1 and alpha2

schedulingv1alpha1 "volcano.sh/volcano/pkg/client/clientset/versioned/typed/scheduling/v1alpha1"
schedulingv1alpha2 "volcano.sh/volcano/pkg/client/clientset/versioned/typed/scheduling/v1alpha2"

Looking at the code you can you see
