Helm delete all releases

Kubernetes Helm Problem Overview

I'm trying find a way to delete all deployed releases in Helm.

It appears that Helm does not support deleting all releases, with --all or otherwise.

Would there be another way to delete all Helm releases in one command?

Kubernetes Helm Solutions

Solution 1 - Kubernetes Helm

To delete all Helm releases in Linux(in Helm v2.X) with a single command, you can use some good old bash. Just pipe the output of helm ls --short to xargs, and run helm delete for each release returned.

helm ls --all --short | xargs -L1 helm delete

Adding --purge will delete the charts as well, as per @Yeasin Ar Rahman's comment.

helm ls --all --short | xargs -L1 helm delete --purge

On Windows, you can delete all releases with this command, again, with --purge deleting the charts as well.

helm del $(helm ls --all --short) --purge

Solution 2 - Kubernetes Helm

For helm 3 you have to provide namespaces so there is an awk step before xargs :

helm ls -a --all-namespaces | awk 'NR > 1 { print "-n "$2, $1}' | xargs -L1 helm delete

This results in commands like:

helm delete -n my-namespace my-release

Solution 3 - Kubernetes Helm

This worked for me in a powershell cmd window:

helm del $(helm ls --all --short) --purge

Solution 4 - Kubernetes Helm

helm delete $(helm ls --short)

Description:

helm ls --short gives a list of releases ids.

helm delete id1 id2 id3 deletes releases with ids: id1, id2, id3.

So combining them we get: helm delete $(helm ls --short)

Solution 5 - Kubernetes Helm

I regularly delete all releases in Helm too, so I thought it'd be useful to make a Helm plugin for it.

Install:

helm plugin install https://github.com/tedmiston/helm-delete-all-plugin --version 0.0.3

(You may be able to omit the --version x part on newer versions of Helm.)

Usage:

helm delete-all

https://github.com/tedmiston/helm-delete-all-plugin

Solution 6 - Kubernetes Helm

There is a really good plugin for delete all helm releases from all namespaces (The previous plugin in this post doesn't work for me) . Install:

helm plugin install https://github.com/BarelElbaz/helm-delete-all

usage:

helm delete-all

you can provide more flags such as --deletePersistent for delete PVCs or skipping a specific namespace by --except-namespace
