If you no longer need your Solo Enterprise for Istio environment, you can uninstall Solo Enterprise for Istio components, such as the management and data plane.

To uninstall Istio service meshes, see the ambient mesh or sidecar mesh uninstall guides.

Single cluster

  1. Uninstall the Solo Enterprise for Istio release.

      helm uninstall gloo-platform -n gloo-mesh

  2. Uninstall any Solo Enterprise for Istio CRDs, such as by deleting the CRD Helm release.

      helm uninstall gloo-platform-crds -n gloo-mesh

    If you do not have a CRD Helm release, check for and manually remove any CRDs.

      kubectl get crds | grep solo
kubectl delete crd <$CRD>

  3. Delete the gloo-mesh namespace.

      kubectl delete namespace gloo-mesh

Multicluster

Before you begin, save the names and contexts of the clusters you want to uninstall Solo Enterprise for Istio from. In these example steps, cluster1/context1 is assumed as the cluster where the management plane is installed.

  export cluster1=<cluster1_name>
export cluster2=<cluster2_name>
export context1=<cluster1_context>
export context2=<cluster2_context>

  1. Uninstall the agent that runs on each connected workload cluster.

      meshctl cluster deregister \
    --kubecontext ${context1} \
    --remote-context ${context2} \
    ${cluster2}

    1. Uninstall the agent Helm release.

        helm uninstall gloo-platform -n gloo-mesh --kube-context ${context2}

    2. Delete the corresponding KubernetesCluster resource from the management cluster.

        kubectl delete kubernetescluster ${cluster2} -n gloo-mesh --context ${context1}

    3. Delete the relay secrets from each connected cluster, as you cannot reuse the same secret if you decide to re-register the agent later.

        kubectl delete secret -n gloo-mesh relay-client-tls-secret --context ${context2}
kubectl delete secret -n gloo-mesh relay-identity-token-secret --context ${context2}
kubectl delete secret -n gloo-mesh relay-root-tls-secret --context ${context2}

    4. Uninstall any Solo Enterprise for Istio CRDs, such as by deleting the CRD Helm release.

        helm uninstall gloo-platform-crds -n gloo-mesh --kube-context ${context2}

      If you do not have a CRD Helm release, check for and manually remove any CRDs.

        kubectl get crds --context ${context2} | grep solo
kubectl delete --context ${context2} crd <$CRD>

  2. Delete the gloo-mesh namespace from each connected cluster.

      kubectl --context ${context2} delete namespace gloo-mesh

  3. Uninstall the management plane components and CRDs from the management cluster.

      helm uninstall gloo-platform -n gloo-mesh --kube-context ${context1}
helm uninstall gloo-platform-crds -n gloo-mesh --kube-context ${context1}

  4. Delete the gloo-mesh namespace from the management cluster.

      kubectl --context ${context1} delete namespace gloo-mesh
