I’m attempting to use Pulumi’s Automation API to update a Digital Ocean Kubernetes Node Pool node count. I’m running into a few issues. When I use 
resource_name="pool-testing-0",
I get Duplicate resource URN What should i be using here?
Copy code
node_pool = digitalocean.KubernetesNodePool.get("pool-testing-0", existing_node_pool_id)
    node_pool_update = digitalocean.KubernetesNodePool(
        resource_name="pool-testing-0", # Duplicate resource URN, but what should it be?
        cluster_id=digital_ocean_cluster_id,
        name=node_pool.name,
        size=node_pool.size,
        # node_count=desired_node_count,
        auto_scale=False,
        min_nodes=node_pool.min_nodes,
        max_nodes=desired_node_count,
        opts=pulumi.ResourceOptions(import_=existing_node_pool_id)
    )
If I set a unique 
resource_name
I get the dreaded “inputs to import do not match the existing resource”.

When importing, they have to match. Pulumi doesn't support importing and updating in a single operation
With the kubernetes provider being the exception, pulumi is designed for owning infrastructure, not updating existing infrastructure owned by something else

Pulumi owns/manages the K8s cluster in question. I’m attempting to adjust the node pool’s node count via the Automation API, but I’m running into constant issues, so it seems like my plan isn’t feasible.

When I adjust the resource name to match, I get a duplicate URN error. 🤷

The resource names need to be unique across the stack, so it's conflicting with the 
.get()
resource
Sorry, unique for each type across the stack
If pulumi created the kubernetes node pool, then you could scale it from the stack it's in. But it looks like you'll need to use the digital ocean api to scale it if you're wanting it to be a separate process

I don’t want HPA, I’m trying to add and remove nodes based on time of day, due to the schedule of the workload on the node pool.
