intercept-lib test instruction doesn't work.

[awang088]

Following the instruction to manually test interpose lib. it doesn't run through and fails at here:

xxx@fw0016741:/home/xxx/dev/alnair/alnair-device-plugin$ sudo go run cmd/alnair-device-plugin/main.go
cmd/alnair-device-plugin/main.go:4:2: cannot find package "alnair-device-plugin/pkg/devicepluginserver" in any of:
/usr/lib/go-1.10/src/alnair-device-plugin/pkg/devicepluginserver (from $GOROOT)
/home/steven/go/src/alnair-device-plugin/pkg/devicepluginserver (from $GOPATH)
xxx@fw0016741:/home/xxx/dev/alnair/alnair-device-plugin$

how to fix this?

Assume you have a two-node kubernetes cluster.

1. install alnair-device-plugin (this way you don't need to build and launch alnair device plugin and vgpu-server manually)
   kubectl apply -f https://raw.githubusercontent.com/CentaurusInfra/alnair/main/alnair-device-plugin/manifests/alnair-device-plugin.yaml
   verify alnair-device-plugin-daemonset-XXXXXX pod is installed under kube-system namespace on the GPU node
2. On the worker GPU node, replace /opt/alnair/libcuinterpose.so with newly built "libcuinterpose.so"
3. launch test pod with alnair/vgpu-memory:4 request (request 4GB gpu memory),
4. bash into the pod, check out the files used/generated by intercept lib in the /var/lib/alnair/workspace
