Hi, is it possible to to provision k8s EKS cluster and deploy some config in a single pulumi run? It seems it is possible in typescript according to the following example, I am wondering if it is possible to achieve it in python
this is how it can be done in TypeScript ^

Yes, of course, you can do it with Python SDK. For example, 
traefik_internal_ip = traefik_chart.get_resource(
    'v1/Service',
    'traefik',
    namespace=traefik_namespace_name,
)
and then manipulate it as you want 
rrdatas=[
        traefik_internal_ip.apply(
            lambda x: x.status['load_balancer']['ingress'][0]['ip']
        ),
    ],

I am not sure I understand. I think the problem I have is specifically related to kubernetes and EKS. Pulumi needs to know where to connect to (to which Kubernetes cluster) when you want to use resources from the pulumi_kubernetes.core.v1 package (like for example the Service class). Normally pulumi takes this from the system wide kubeconfig file but if the Kubernetes cluster itself is being provisioned during the pulumi up I need to somehow retrieve configuration details of newly provisioned kubernetes cluster and make pulumi to use them when provisioning further kubernetes objects
and I don't see how python implementation of EKS exposes this kubeconfig stuff. For example the microsoft version - the aks container service exposes it via "kube_config_raw"
and the above example I posted in the screenshot does it too in the TypeScript
but in python there seems to be no such possibility for eks

the EKS module is available in python @boundless-angle-56560 - it should have the same outputs in all languages
did you give it a try, or do you need an example?

@billowy-army-68599 I use this:
from pulumi_aws import eks
eks_cluster = eks.Cluster( 'prm-eks-cluster', role_arn=eks_iam.eks_role.arn, tags={ 'Name': 'pulumi-eks-cluster', }, vpc_config=eks.ClusterVpcConfigArgs( public_access_cidrs=['0.0.0.0/0'], security_group_ids=[eks_vpc.eks_security_group.id], subnet_ids=eks_vpc.subnet_ids, ), )
but that object doesn't have a property that would give me a provider like in the typescript example from my screenshot

from what I understood the typescript example leverages crossplane while my example uses raw aws module
as crossplane is not available in python

this appears to work for me 
"""An AWS Python Pulumi program"""

import pulumi
import pulumi_eks as eks

cluster = eks.Cluster("python")

pulumi.export("kubeconfig", cluster.kubeconfig)

wait, sorry I see now
you need to use our EKS provider: https://github.com/pulumi/pulumi-eks
you're importing the plain EKS resource from the AWS provider, we have a much more fully featured option above ^^
if you want to do this manually, you can construct your kubeconfig manually https://github.com/pulumi/examples/tree/master/aws-py-eks but I'd recommend using the EKS provider

aham that makes sense, for some reason I didn't know that it is available
probably all examples cointained the raw module :))
oh my do I love pulumi, its actually working
I did the raw version with the util thing but I suppose the high level module will work too

you have a lot of flexibility, it's best to do what you need!
