I’ve filed a bug

thx - any idea for an ETA?

Hmmm, it might have to be next week, I think we will have to add a

Crd

class, and it’s not clear to me yet what the implications of this are.

But, it is important to add.

And another question: I have two Output<string> values, and I would like to combine them to create a new Output<string>. How could I do this?

Use case is like this:

gray-city-50684

08/27/2018, 5:40 PM

const clusterName = k8sCluster.name; const resourceGroupName = k8sResourceGroup.name;

gray-city-50684

08/27/2018, 5:40 PM

and I would like to output:

gray-city-50684

08/27/2018, 5:41 PM

az aks get-credentials --resource-group ${resourceGroupName} --name ${clustername}

creamy-potato-29402

08/27/2018, 5:42 PM

SOmething like:

Copy code

pulumi
    .all([k8sCluster.name, k8sResourceGroup.name])
    .apply([cluster, group] => `az aks get-credentials --resource-group ${resourceGroupName} --name ${clustername}`)

np let me know of any other problems

Is there any easy way to take a folder of just raw k8s yaml and apply it to cluster? Or in that case would I convert to json put it in my typscript as variable and apply it maybe?

flaky-receptionist-88878

08/27/2018, 8:06 PM

Or is that approach with Pulumi against the grain?

@flaky-receptionist-88878 one of the main reasons for something like Pulumi is the resource dependency graph which can't be represented in the yaml

important-jackal-88836

08/27/2018, 9:05 PM

if you don't want to convert everything to code to take advantage of that, then personally I would just apply the yaml the old-fashioned way

Incidentally, we do have support for using raw YAML: https://github.com/pulumi/pulumi-kubernetes/blob/master/pack/nodejs/provider.ts#L742-L763

kubernetes.yaml.ConfigGroup

is your friend here.

microscopic-florist-22719

08/27/2018, 9:08 PM

@flaky-receptionist-88878 you can use the options to indicate a set of YAML files that the Pulumi Kubernetes library will parse and convert into equivalent Pulumi resources. There's a direct mapping for each YAML construct, so the resulting resources faithfully represent the objects in the YAML. @creamy-potato-29402 can correct me on any subtleties 🙂

creamy-potato-29402

08/27/2018, 9:22 PM

@flaky-receptionist-88878 yes, @microscopic-florist-22719 is correct. There’s an example here: https://github.com/pulumi/pulumi-kubernetes/blob/master/examples/yaml-guestbook/index.ts

Copy code

import * as k8s from "@pulumi/kubernetes";

// Create resources from standard Kubernetes guestbook YAML example.
const guestbook = new k8s.yaml.ConfigGroup("guestbook", { files: "yaml/*.yaml" });

// Export the (cluster-private) IP address of the Guestbook frontend.
const frontend = guestbook.getResource("v1/Service", "frontend");
export const frontendIp = frontend.spec.apply(spec => spec.clusterIP);

also cc @important-jackal-88836 🙂

I take that back... there are still lots of other reasons to use Pulumi like centralized management and outputs.

lol, this was always intended to make the upgrade path smooth. My favorite reason is that the pulumi CLI just makes it easy to know whether your deployment succeeded.

important-jackal-88836

08/27/2018, 9:27 PM

and outputs of yaml could be integrated into a dependency graph after all

Is there any documentation on self-hosting instead of relying on pulumi.com?

important-jackal-88836

08/27/2018, 10:21 PM

how might one make a kubernetes namespace if it doesn't exist or otherwise export existing?

important-jackal-88836

08/27/2018, 10:41 PM

ObjectReference throws error, getResource requires a Provider instance and I don't know how to access that...

creamy-potato-29402

08/27/2018, 10:41 PM

hmm I’m not sure I understand?
