Hi all, At the moment I have a cronjob that makes a snapshot every x minutes of a given pvc in a namespace. It does this by using a new image using the Pulumi cli image as a base image and adds a small Pulumi project that makes a new snapshot and deletes the previous one every-time it runs. Now this is all working fine, but there is one small issue. I need the value 
Snapshot Handle
 from the volumesnapshotcontent resource that is generated automatically when making a new snapshot. Because it's generated automatically it is not a pulumi resource, so as far as I know I can't get that value using pulumi. I wanted to use pulumi for it so I can save it as a stackreference and use it in different places in my infrastructure. I tried using query-kubernetes, because I can get the name of this volumesnapshotcontent from the volumesnapshot itself, but this package does not support crd's. Anyone an idea on how I could achieve this? (I thought of using a kubectl container to get it, but I would prefer to keep it all pulumi)

you could talk to the kubernetes api directly using your language of choice
put the code with your pulumi stack and then import the resource if neeeded

Pulumi allows you to execute any piece of code - even code that doesn't use it's API directly ``````
Example: https://www.pulumi.com/blog/deploying-mysql-schemas-using-dynamic-providers/ This example uses the 
mysql-connector-python
module, it's referred to in requirements You can use any upstream code base and/or build your own that can be called when running your stack

If you're using python check out https://github.com/kubernetes-client/python
actually looks like there's one for each language

This can work really well for my purpose. I use typescript so the javascript version should fit me well. Then it won't be completely pulumi, but I can at-least write it in the same project. And also looks easier then using the dynamic providers.
Btw using the kubernets client was the way to go. I was able to get the information I needed like so:
Copy code
const k8sApi = kc.makeApiClient(CustomObjectsApi);
const volumeSnapshotContents = await k8sApi.listClusterCustomObject("<http://snapshot.storage.k8s.io|snapshot.storage.k8s.io>","v1","volumesnapshotcontents");
