Uninstall Astra Data Store preview
To uninstall Astra Data Store preview, you will remove workloads, bindings, volumes, export policies, clusters, license, deployment environment, and the Astra Data Store preview namespace.
Root administrative permissions
The Astra Data Store preview uninstallation process guides you through the following high-level steps:
Remove existing workloads and bindings
Before uninstalling Astra Data Store preview, you must first remove the following
All application workloads that use Astra Data Store preview as the storage backend
Trident bindings that use Astra Data Store preview as a backend
This ensures that your Kubernetes environment is left in a clean state, which is important if you reinstall.
Uninstall the Astra Data Store preview cluster and control plane
Follow the steps below to uninstall Astra Data Store preview manually.
Delete the volumes and export policies
Before deleting the cluster, you should delete the Astra Data Store preview volumes and export policy.
|If you do not first delete volumes and export policies, the cluster deletion process pauses until the Astra Data Store preview volumes objects are deleted. It is more efficient to remove those items before starting to delete the cluster.|
Delete the volumes:
~% kubectl delete astradsvolumes --all -A ~% kubectl get astradsvolumes -A
Delete the export policies:
~% kubectl delete astradsexportpolicies --all -A ~% kubectl get astradsexportpolicies -A
Delete the Astra Data Store preview cluster
Deleting the cluster deletes only the Astra Data Store preview cluster object custom resource (CR) along with cluster-scoped resources.
|The operator, nodeinfo pods, and the cluster controller (which are Kubernetes-scoped resources) remain even after the cluster is deleted.|
Deleting the cluster also uninstalls the underlying operating system from the nodes, which will stop the
The uninstaller takes about a minute to finish. Then, the removal of the Astra Data Store preview cluster-scoped resources starts.
Delete the cluster:
~% kubectl delete astradsclusters --all -A ~% kubectl get astradsclusters -A
Delete the license
ssh to each worker node in the cluster and validate that
netwdare not running in the worker nodes.
Delete the Astra Data Store preview license:
~% kubectl delete astradslicenses --all -A ~% kubectl get astradslicenses -A
Delete the Astra Data Store preview installation
Delete the controllers, operators, namespace, and support pods in the cluster.
Delete the Astra Data Store preview installation object:
~% kubectl delete astradsversion atradsversion -n astrads-system ~% kubectl get astradsversion -n astrads-system
Delete the data store DaemonSets and all Astra Data Store preview controller resources:
~% kubectl delete ds --all -n astrads-system ~% kubectl get ds -n astrads-system ~% kubectl delete deployments --all -n astrads-system ~% kubectl get deployments -n astrads-system
Delete remaining artifacts and the operator yaml file:
~% kubectl delete -f ./manifests/astradsoperator.yaml ~% kubectl get pods -n astrads-system
Validate the removal of the astrads-system namespace
Ensure that the following command returns no result:
~% kubectl get ns | grep astrads-system
Ensure containers are not running on worker nodes
Validate that containers such as
netwd are not running on the worker nodes.
Run the following on each node.
ssh <mynode1> # runc list
Delete OpenShift Container Platform resources
If you installed Astra Data Store preview on Red Hat OpenShift Container Platform (OCP), you can uninstall OCP security context constraints (SCC) and rolebindings resources.
OpenShift uses security context constraints (SCC) that control the actions that a pod can perform.
After you complete the standard uninstall process, complete these steps.
Remove SCC resources:
oc delete -f ads_privileged_scc.yaml
Remove rolebindings resources:
oc delete -f oc_role_bindings.yaml
Ignore "resources not found errors" in these steps.
/var/lib/kubelet/config.yamlfrom all Kubernetes nodes.
