Common Setup - step-by-step#

The following steps create a deployment of KubeStellar Core

  1. You may want to set -e in your shell so that any failures in the setup or usage scenarios are not lost.

  2. If you ran through these scenarios previously then you will need to do a bit of cleanup first. See how it is done in the cleanup script for our E2E tests (in test/e2e/common/cleanup.sh).

  3. Set environment variables to hold KubeStellar and OCM-transport-plugin desired versions:

    export KUBESTELLAR_VERSION=0.23.0-rc2
export OCM_TRANSPORT_PLUGIN=0.1.10

  4. Create a Kind hosting cluster with nginx ingress controller and KubeFlex controller-manager installed:

    kflex init --create-kind
    If you are installing KubeStellar on an existing Kubernetes or OpenShift cluster, just use the command kflex init.

  5. Update the post-create-hooks in KubeFlex to install kubestellar with the desired images:

    kubectl apply -f https://raw.githubusercontent.com/kubestellar/kubestellar/v${KUBESTELLAR_VERSION}/config/postcreate-hooks/kubestellar.yaml
kubectl apply -f https://raw.githubusercontent.com/kubestellar/kubestellar/v${KUBESTELLAR_VERSION}/config/postcreate-hooks/ocm.yaml

  6. Create an inventory & mailbox space of type vcluster running OCM (Open Cluster Management) in KubeFlex. Note that -p ocm runs a post-create hook on the vcluster control plane which installs OCM on it. This step includes the installation of the status add-on controller. See here for more details on the add-on.

    kflex create its1 --type vcluster -p ocm

  7. Create a Workload Description Space wds1 in KubeFlex. Similarly to before, -p kubestellar runs a post-create hook on the k8s control plane that starts an instance of a KubeStellar controller manager which connects to the wds1 front-end and the its1 OCM control plane back-end. Additionally the OCM based transport controller will be deployed.

    kflex create wds1 -p kubestellar

  8. (optional) Check relevant deployments and statefulsets running in the hosting cluster. Expect to see the kubestellar-controller-manager in the wds1-system namespace and the statefulset vcluster in the its1-system namespace, both fully ready.

    kubectl --context kind-kubeflex get deployments,statefulsets --all-namespaces
    The output should look something like the following:
