router-sidecar

• The Slice Router is a network service component that provides a virtual L3 IP routing functionality within a cluster for the Slice overlay network.
• Each slice in a cluster has one slice router with the possibility of a redundant pair option.
• The Slice Operator manages the lifecycle of a Slice Router by overseeing the deployment, configuration, continuous monitoring, and management of the Slice Router.
• The Slice Router provides a full mesh network connectivity between the application pods and slice gateway pods in a cluster.

Build Docker Images

1. Clone the latest version of router-sidecar from the master branch.

   git clone https://github.com/kubeslice/router-sidecar.git
   cd router-sidecar

2. Edit the VERSION variable in the Makefile to change the docker tag to be built. The image is set as docker.io/aveshasystems/router-sidecar:$(VERSION) in the Makefile. Modify this if required.

   make docker-build

Run Local Image on a Kind Cluster

1. You can load the router-sidecar docker image into the kind cluster.

   kind load docker-image my-custom-image:unique-tag --name clustername

   Example

   kind load docker-image aveshasystems/router-sidecar:1.2.1 --name kind

2. Check the loaded image in the cluster. Modify the node name if required.

   docker exec -it <node-name> crictl images

   Example.

   docker exec -it kind-control-plane crictl images

Deploy Router Sidecar on a Cluster

Update the chart values file, yourvaluesfile.yaml that you have previously created. Refer to the values.yaml to create yourvaluesfiel.yaml and update the routerSidecar image subsection to use the local image.

From the sample:

routerSidecar:
  image: docker.io/aveshasystems/kubeslice-router-sidecar
  tag: 0.1.0

Change it to:

routerSidecar:
  image: <my-custom-image>
  tag: <unique-tag>

Deploy the Updated Chart

make chart-deploy VALUESFILE=yourvaluesfile.yaml

Verify the Installation

Verify the installation by checking the status of router-sidecar pods belonging to the kubeslice-system namespace.

kubectl get pods -n kubeslice-system | grep vl3-slice-* 

Example output

vl3-slice-router-red-5b9df8d4dd-hkgkj      2/2     Running   0          26m
