Build process

After making any modification to source files, below steps can be followed to build and use the new binary/images.

Note that you should install genie first before making changes to the source. This ensures genie conf file is generated successfully.

If changes to be made in admission controller and/or policy controller, then make sure to install the respective component with container image pull policy as 'IfNotPresent'.

Please make sure to run the below commands with root privilege.

Building and Using Genie plugin:

Build genie binary by running:

make plugin

Place "genie" binary from dest/ into /opt/cni/bin/ directory.

cp dist/genie /opt/cni/bin/genie

Building and Using network admission controller image:

Admission controller image can be built by runnig:

make admission-controller

This will create a new image with the tag 'quay.io/huawei-cni-genie/genie-admission-controller:latest'.

Load this image with the same tag in the required node and then delete the genie-admission-controller pod runnig in that node. A new pod will automatically come up with the newly loaded image.

kubectl delete pod <genie-admission-controller pod name> -nkube-system

Building and Using network policy controller image:

Network policy controller image can be built by running:

make policy-controller

This will create a new image with the tag 'quay.io/huawei-cni-genie/genie-policy-controller:latest'.

Load this image with the same tag in the required node and then delete the genie-policy-controller pod runnig in that node. A new pod will automatically come up with the newly loaded image.

kubectl delete pod <genie-policy-controller pod name> -nkube-system

Test process

Unit Testing:

To run unit test, execute below command:

make test

make test-e2e testKubeVersion=1.7 testKubeConfig=/etc/kubernetes/admin.conf

If Kubernetes cluster is 1.5.x

make test-e2e testKubeVersion=1.5
