Uninstalling LM Container Services using LM Container Helm Chart

Important: This applies to LM Container services using LM Container Helm Chart 1.0.0 or later.

This topic describes how to uninstall LM Container using the unified Helm Chart.

You may need to uninstall LM Container to start a fresh LM Container installation.

Considerations

Ensure you are operating in the appropriate context on the machine where you are running Helm and kubectl.
Take a backup of previous Helm chart configurations. For more information, see Migrating Existing Kubernetes Clusters Using LM Container Helm Chart.
Ensure you have administrator role privileges. For more information, see Roles.

Open the command line interface window.
In the terminal, run the following Helm command to uninstall the existing Argus and Collectorset-Controller from a Kubernetes cluster:
helm uninstall lm-container -n <respective namespace>
Delete the Custom Resource Definition (CRD) object by using the following command:
kubectl delete crd collectorsets.logicmonitor.com

Note:

The CRD object doesn’t get deleted with the uninstall Helm command. You have to manually delete the CRD.
ConfigMaps created by argus get deleted automatically through Helm uninstall. Use the following command if it doesn’t get automatically uninstalled from the cluster:
$ export ARGUS_SELECTOR="app.kubernetes.io/name=argus,app.kubernetes.io/instance={{ .Release.Name }}" kubectl delete configmaps -l $ARGUS_SELECTOR,argus.logicmonitor.com/cache==true
