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?

Answer 1

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.

Answer 2

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

Answer 3

This worked for me in a powershell cmd window:

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

Answer 4

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)
