Helm delete all releases

Question

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?

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

Update: As per @lucidyan comment, the --purge arg is not available in Helm v3.

there might be some times where you want to delete even the deleted charts then you can use it like this `helm ls --all --short | xargs -L1 helm delete --purge` – Yeasin Ar Rahman Jun 12 '18 at 09:19

Is "-L1" option really required? Seems to be working without it too. – demisx Jul 31 '19 at 19:12

@demisx: The `-L1` is not required. This arg is for max lines, which defaults to one anyway, so in this case it is not needed. – grizzthedj Jul 31 '19 at 23:31
`-L` option is not in busybox. – Lei Yang Nov 06 '19 at 09:37

Note than `--purge` flag is not available in Helm 3 – lucidyan Dec 20 '19 at 13:59

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

This is the correct and cross-platform answer which takes namespaces into account. – Skyblade Feb 22 '21 at 12:42

This worked for me in a powershell cmd window:

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

For Windows PS this is indeed the correct answer, the accepted answer does not work on Windows. – Ahab Apr 16 '19 at 13:21
`helm del $(helm ls --all --short |grep test) --purge` to delete and purge only deletes release starting with test name. – Vikas Apr 23 '20 at 15:58

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)

While this code may answer the question, providing additional context regarding **how** and **why** it solves the problem would improve the answer's long-term value. – Alexander Jun 14 '18 at 13:24

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

If you use xargs in the alpine container then you will get the following error;

xargs: unrecognized option: L

So, you can use the following command to delete all releases in a specific namespace for the helm v3.

helm uninstall -n <namespace> $(helm ls --short -n <namespace>)

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
