Hi @kaskol10. Thanks for your PR.
I'm waiting for a kubernetes-csi member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test
on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.
Once the patch is verified, the new status will be reflected by the ok-to-test
label.
I understand the commands that are listed here.
Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Please include CRDs into chart as well.

According to stevehipwell, is it really a good practice to install CRDs part of a helm chart ?
@SamuelBagattin Helm isn't able to manage full lifecycle of CRDs, that's true, but it is quite capable of installing CRDs if there is none. Which solves initial deployment task. It's common practice on CRDs change to bump major chart version and provide instructions how to update CRDs, check out https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack.
Great work, @kaskol10 , many thanks! Any progress here on this PR? In the past we had our own Helm chart for CRDs, before the snapshot controller manager was removed from OpenStack Cinder CSI Chart and it's not available anymore since openstack-cinder-csi-2.0.0. Would be a good idea to have a fast replacements, thx!
Hi @kaskol10 🙌 It's been a while there has been no more commit on this PR, and the helm chart would really help us 😊 Any update ?

My concern with this is continued support of helm charts by the maintainers, I am not sure if that's something the team would have the bandwidth to do for every release. I'll defer to @xing-yang as to if we want to continue maintaining helm charts for the snapshot-controller in this repo.

Thanks @kaskol10 for your contribution. As mentioned by @ggriffiths, that's exactly the concern we have.
We too would really like an easy way to actually install this.. What other way do you recommend, instead of using a Helm Chart?

The deployment files under deploy/kubernetes will work. We maintain those for every release with new flags/RBAC/etc.
If there's enough interest, maybe you can create a separate repo to house and maintain the Helm installation.

Maybe the solution is to generate the plain manifests from the helm chart (and add a pipeline to ensure. WDYT?
NB: there is also helmify to create charts from plain manifests.
Just FYI, there are helm charts already available at https://github.com/piraeusdatastore/helm-charts. It's perfectly fine, if project maintainers don't want to support helm chart, helm community can help with existing chart maintained by 3rd party.

How it's done isn't a concern, I just don't think there's enough contributor bandwidth to maintain that for every release. I would suggest setting up a community repo to maintain these charts.
I need this helm.

I would use a Helm chart if one were available.
One maybe overlooked feature of using helm charts - is that they make it MUCH easier to automate monitoring for version updates, in a standardized way. We actually just have a script that looks through all our application helm charts (from upstream) - and talks to helm repo - to see if a new version exists.. Making it work pretty much like good old Linux repos - for k8s.
Everyone who still comments here. Have you seen https://github.com/piraeusdatastore/helm-charts/tree/main/charts/snapshot-controller? It was linked here at https://github.com/kubernetes-csi/external-snapshotter/pull/622#issuecomment-1126292632. Have you tried it? Is it missing something? There is already existing fully functional helm chart available.
We are following the piraus charts - but IMHO its important that charts are "maintained alongside the code it installs" - as any other "release package". Thats the learnings from Helms "once upon a time - central package repository" - which was discontinues because things bitrot, when they don't live together. The install guide of this project SHOULD list the helm chart - and frankly I don't understand the hesitance to do so, when helm packages has such a huge advantage over "raw yaml" - for the users of the project (making k8s app maintenance much easier to do - as automation for monitoring for updates etc. . is made so much easier).
I don't buy it. History of "central package repository" doesn't have anything to do with this case. Instead Helm enables anyone to package some manifests in a way they want to and distribute them. Project maintainers aren't obliged to provide a helm chart. This project isn't a unique case of not providing charts. Instead we see a raise of 3rd party repos that package multiple different projects (like https://github.com/bitnami/charts/tree/main/bitnami or https://github.com/deliveryhero/helm-charts/tree/master/stable), which is a good thing as this offloads burden from project maintainers and actually reduces chance of bitrot.
