Uninstall and Cleanup

The process of uninstalling requires one to navigate to the installer directory and execute the following command

./appviewxctl uninstall --config .appviewxctl.yaml

The following messages are displayed after the uninstall command is executed successfully.

Note: In the Managed K8s environments removal of PVCs do not occur at times as it may require patching PVCs first before deletion. This may cause certain error messages to display, indicating that PVC has changed. In case of such an error occurs re-run the above command to solve the issue and uninstall the application.

Sometimes the namespaces take a longer time to be removed. Hence, post installation, check if namespaces are in the terminating state (use the command: kubectl get namespace). If any namespace is in the terminating state, manually remove the namespaces by executing the commands below:

kubectl get namespace "istio-operator" -o json | tr -d "\n" | sed "s/\"finalizers\": \[[^]]\+\]/\"finalizers\": []/" | kubectl replace --raw /api/v1/namespaces/istio-operator/finalize -f - 2>/dev/null

kubectl get namespace "istio-system" -o json | tr -d "\n" | sed "s/\"finalizers\": \[[^]]\+\]/\"finalizers\": []/" | kubectl replace --raw /api/v1/namespaces/istio-system/finalize -f - 2>/dev/null

kubectl get namespace "avx" -o json | tr -d "\n" | sed "s/\"finalizers\": \[[^]]\+\]/\"finalizers\": []/" | kubectl replace --raw /api/v1/namespaces/avx/finalize -f - 2>/dev/null

kubectl get namespace "avx-kafka" -o json | tr -d "\n" | sed "s/\"finalizers\": \[[^]]\+\]/\"finalizers\": []/" | kubectl replace --raw /api/v1/namespaces/avx-kafka/finalize -f - 2>/dev/null

kubectl delete ns istio-operator --force 2>/dev/null

kubectl delete ns istio-system --force 2>/dev/null

kubectl delete ns avx --force 2>/dev/null

kubectl delete ns avx-kafka --force 2>/dev/null
