kubeslice-worker operator

The kubeslice-worker operator manages the life-cycle of KubeSlice worker cluster related custom resource definitions (CRDs). kubeslice-worker operator uses Kubebuilder, a framework for building Kubernetes APIs using CRDS.

Getting Started

It is strongly recommended to use a released version.

For information on installing KubeSlice on kind clusters, see getting started with kind clusters or try out the example script in kind-based example.

For information on installing KubeSlice on cloud clusters, see getting started with cloud clusters.

Installing kubeslice-worker in Kind Cluster

Prerequisites
Local Build and Update
Latest Docker Hub Image
docker pull aveshasystems/worker-operator:latest
Setting up Your Helm Repo

If you have not added avesha helm repo yet, add it.

helm repo add avesha https://kubeslice.github.io/charts/

Upgrade the avesha helm repo.

helm repo update
Getting Secrets from Controller Cluster (if it's not already done)

The following command will fetch the relevant secrets from controller cluster and copy them to secrets folder. It will also output them so that we can use it to populate helm chart values.

deploy/controller_secret.sh [controller_cluster_context] [project_namespace] [worker_cluster_name]

Example

deploy/controller_secret.sh gke_avesha-dev_us-east1-c_xxxx kubeslice-cisco my-awesome-cluster
Build Docker Images
  1. Clone the latest version of worker-operator from the master branch.
git clone https://github.com/kubeslice/worker-operator.git
cd worker-operator
  1. Adjust VERSION variable in the Makefile to change the docker tag to be built. Image is set as docker.io/aveshasystems/worker-operator:$(VERSION) in the Makefile. Change this if required.
make docker-build
Running the Local Image on Kind Cluster
  1. You can load the operator on your Kind cluster with the below command.
kind load docker-image <my-custom-image>:<unique-tag> --name <cluster-name>

example:

kind load docker-image aveshasystems/worker-operator:1.2.1 --name kind
  1. Check the loaded image in the cluster. Modify node name if required.
docker exec -it <node-name> crictl images

example:

docker exec -it kind-control-plane crictl images
Deploying in a Cluster

Create chart values file yourvaluesfile.yaml. Refer to values.yaml to create yourvaluesfile.yaml and update the operator image subsection to use the local image.

From the sample:

operator:
  image: docker.io/aveshasystems/worker-operator
  tag: 0.2.3

Change it to:

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

Deploy the Updated Chart

make chart-deploy VALUESFILE=yourvaluesfile.yaml
Verify if the Operator is Running
kubectl get pods -n kubeslice-system
