I've found this: https://www.pulumi.com/docs/guides/crosswalk/kubernetes/apps/#deploy-a-helm-chart but man, I miss simplicity of 
helm install
I'm not managing to convert this to python

what are you struggling with? I've done this with typescript but can quickly throw a python example together if you need?

well mainly, why do we need 
transformations
and how to convert it to python...

you dont need that, its an example of if you wanted to put it in a different namespace thats all
in the real world you'd configure that normally by specifying the helm chart values for the namespace options, but transformations lets you do things which arent supported by the helm chart values

as @better-rainbow-14549 says, transformations are optional. They are extremely useful in situations where your helm chart doesn't have a configuration option in the 
values.yaml
. I use them often for things like charts that don't support podsecurity policies

I'm having even more basic problems...
Copy code
import pulumi_kubernetes
pulumi_kubernetes.helm.v3.Chart('nginx', config={}
has error 
AttributeError: module 'pulumi_kubernetes' has no attribute 'helm
but according to the docs it has https://www.pulumi.com/docs/reference/pkg/python/pulumi_kubernetes/helm/v3/
ok, time to get hands dirty I guess 😞
ahhh... I MUST import it first, can't use it directly 😞 
from pulumi_kubernetes.helm import v3
and even after this it's not that easy as in TS 😞 I probably miss examples how to use helm in python

I thought we had an example in our examples repo, but you're right! We don't. I've cut this issue to get that fixed https://github.com/pulumi/examples/issues/671

hmmm, I can make some draft that might help...
Copy code
nginx = Chart('nginx', config=ChartOpts(
    repo='stable',
    chart='nginx-ingress',
    version='0.30.0',
    namespace=b81_namespace.metadata['name']
), opts=ResourceOptions(provider=k8s_provider))
in case you'll need it...
just... 
helm list
does not see it anymore but I can leave without it
and it can't recognize the 
Deployment
so pulumi tries to apply it each time when i run 
pulumi up
... hmmm
I don't want to spam but, 
helm list
should not work anyway because it's managed by pulumi (althought it would be cool if to use help list) Another thing that I've learn is that I must have helm on my machine + configured 
helm repo add stable <https://kubernetes-charts.storage.googleapis.com>
