How to delete all resources from Helm list by one command?

Question

List installed Helm resources:

$ helm ls
NAME                REVISION    UPDATED                     STATUS      CHART               NAMESPACE
myresource1         1           Fri Jan 19 10:00:02 2018    DEPLOYED    my-chart-1.0.0      default
myresource2         1           Sat Jan 20 10:01:01 2018    DEPLOYED    my-chart-2.0.0      default
myresource3         1           Sun Jan 21 10:02:02 2018    DEPLOYED    my-chart-3.0.0      default

There is a way to delete one resource:

Is it possible to delete all resources one time?

Answer 1

I don't think there is a built-in way of doing it, but you can use some good old bash

helm list --short | xargs -L1 helm delete

Remember to add the --purge flag if you want to delete everything related to the release.

Answer 2

In short and only with helm commands you can use:

helm delete $(helm list --short)
