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?
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/astronomerio/helm-delete-all-plugin --version 0.0.2(You may be able to omit the --version x part on newer versions of Helm.)
Usage:
helm delete-allTo delete all Helm releases(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.
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
This worked for me in a powershell cmd window:
helm del $(helm ls --all --short) --purgehelm delete $(helm ls --short)
Description:
helm ls --short gives a list of releases ids.
helm delete id1 id2 id3 deletes realeses with ids: id1, id2, id3.
So combining them we get: helm delete $(helm ls --short)
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
