`Apps installed to Kubernetes can rarely be uninstalled in a single command
|
|
and often leave clusters in an inconsistent state. Kubernetes does not
|
|
track resources created by applications in the same way that something like
|
|
Windows 10 or MacOS would do, so it is often much easier for you to
|
|
create a new cluster, than to remove an application.
|
|
|
|
With a tool like kind, you just run:
|
|
|
|
kind delete cluster; kind create cluster
|
|
|
|
Most arkade apps are installed with helm, so you can simply use helm to
|
|
remove them, but beware that each project generally provides very specific
|
|
guidance on how to clear up all resources that it may have created
|
|
at installation time.
|
|
|
|
Get helm:
|
|
arkade get helm
|
|
|
|
List charts:
|
|
helm list --all-namespaces
|
|
|
|
Delete a chart:
|
|
helm delete -n openfaas openfaas
|
|
|
|
Delete any namespaces it created:
|
|
kubectl delete namespace openfaas openfaas-fn
|
|
|
|
Where an app was installed via manifest files or an upstream CLI like
|
|
with linkerd or OSM, then you can usually delete its namespace,
|
|
however this does not always remove all resources such as a
|
|
ClusterRole. See the app's code for more:
