Hey guys, we are deploying helm charts and trying to figure out a way to depend on underlying resources of the chart. In Python I see there is a get_resource method on a v3 chart but it returns a Output[CustomResource] and not a Resource so I am unable to add it as a depends_on resource. Do you know a way to do this or is it not possible right now? here is an example. I wanted to extract the deployment of the cert-manager chart but that variable is an Output[CustomResource] and not a Resource so I am unable to use it.

cert_manager_deployment = cert_manager_chart.get_resource(group_version_kind="apps/v1/Deployment",
                                                          name="cert-manager",
                                                          namespace="cert-manager")

Trying to use that ends up with this exception

Exception: 'depends_on' was passed a value that was not a Resource.

anyone that has a concrete example configuring a traefik ingress using version 2 of traefik?

Hi, I'm struggling with a k8s.yaml.ConfigFile (a certManager's ClusterIssuer) which won't get created but i don't see any errors in the provisioning. I already tried to refresh this resource but that din't helped. Any hints on how to troubleshoot this?

I think, I’ve asked this question already, and answer was to use dynamic provider, possibly after 2 months something changed, just trying to double check. For example I am deploying StatefulSet (elasticsearch operator) that manages resources in my cluster, what will be the easiest way to wait for

export const elasticService = k8s.core.v1.Service.get(
  'elastic-lb',
  pulumi.interpolate`${namespace.metadata.name}/${elastic.metadata.name}-es-http`,
  { parent: namespace, dependsOn: elastic, provider: aks.k8s.provider }
);

elasticService

- I need to wait for this resource to appear, instead of failing instantly on preview step? Thanks!

Is there a special process required to do something like

helm upgrade

via pulumi?

quaint-electrician-41503

I currently deploy a chart like

Chart("some-name,config=LocalChartOpts(path=path/to/helm-chart,ns=...,values=custom_values))

quaint-electrician-41503

10/29/2020, 5:43 PM

Can I just update my path to helm chart to the latest version and pulumi will deploy an update?

quaint-electrician-41503

10/29/2020, 5:52 PM

Seems like this would be good documentation. Maybe I will just export my values and upgrade via helm for now since I don't know if this will work otherwise

@billowy-army-68599 @gorgeous-egg-16927 Does the Pulumi Helm v3 support helm hooks “pre-install,pre-upgrade”? I am trying to render out a chart that includes jobs with those hook types but it doesn’t seem to be rendering them at all which breaks the deployment.

Is there a way to timeout a deploy to kubernetes faster if sometehing isn't correct?

Is there a way to leverage a helm chart from a git repo that isnt setup as a helm repo? For example, the istio gateways helmchart does not have an

index.yaml

so I cant simply place it in

fetchOpts:{
  repo:"<https://github.com/istio/istio/tree/master/manifests/charts/gateways/istio-ingress>",
},

Ive been using path but I would prefer to source it remotely each time rather than have the chart local to my git repo.

Hi 🙂 Is it possible with Pulumi to update an existing config map? I have a chart (Nginx ingress) that creates a config map, and soo after I want to add keys to that configmap. I know how to create a cm with Pulumi but not this. Thanks!

Hi all, how one specifies the namespace where to apply new k8s.yaml.ConfigFile?

Has anyone experienced any issues with the Helm provider failing to create resources seemingly at random? I am trying to deploy the Nginx ingress helm chart and sometimes it works fine, other times it will fail to deploy the service account, or the role, or the PSP, always throwing a "System.NullReferenceException: Object reference not set to an instance of an object." error. Whenever I attach a debugger to try and get more info, it always works. Any ideas on how I can look into this?

Hey all, is there a recommended approach for adding a label to an already existing namespace "default" (using Go), was looking quickly at the SDK and it seemed to be limited to newly created namespaces only, and testing it quickly confirmed it.

_, err = k8s.NewNamespace(ctx, "default", &k8s.NamespaceArgs{
		Metadata: &meta.ObjectMetaArgs{
			Labels: pulumi.StringMap{"foo": pulumi.String("bar")},
		},
	}, pulumi.Provider(input.K8sProvider))
	if err != nil {
		return err
	}

Is there any documentation available on what "verbs" (get, apply, patch, create etc) pulumi is using, and for what action, when applying changes to the cluster?

Hi, Is there a way to patch kubernetes system resources? My use case is to add labels and annotations to the kube-system namespace but I don’t want to take over the namespace as a full import?

I'm every now and then getting this kind of issue during a stack refresh, and it ends up deleting these resources from the stack state. I'm not sure why this is happening, but I'm wondering if it is due to our OIDC cluster authentication setup with short lived access tokens & refresh tokens. 1. Could this error occur when my token for the cluster expires? 2. Should the refresh command really delete resources from state if fails connecting to the cluster? CLI wise it’s fine, I can just select no, but in some tools we use the automation api and then the refresh is performed anyway.

configured Kubernetes cluster is unreachable: failed to parse kubeconfig data in `kubernetes:config:kubeconfig`- couldn't get version/kind; json parse error: json: cannot unmarshal string into Go value of type struct { APIVersion string "json:\"apiVersion,omitempty\""; Kind string "json:\"kind,omitempty\"" }

Is there a way to use the

type definition that

PodBuilder

uses? It doesn’t appear to be exported from

@pulumi/kubernetesx

Hi everyone, i'm a bit lost with the kubernetes-sdk in Go. I don't see how we can provide for our developers a simple way to use reusable libraries. My idea is to provide for example a library adding a volume and a volume mount to every deployment. Really a simple chain of modification like we would do with the go sdk.

deployment, err := MyCustomGen(name)
err = MyCustomDeploymentPatch(deployment)

I might be missing something bu i don't see how it's feasible with the pulumi-sdk. My question basically is how can we do two-pass modification on any object.

Hi, I’m installing the linkerd helm chart which requires one of the values to be a multiline string, but I can’t see how to do that using Pulumi. I’m using TypeScript. What is the proper way to do this?

hey all, was looking over some of the diff logic in the provider and noticed what seems like a bug to me - i think this call should be

labelSelectorForceNewProperties(".spec.selector")

instead, since `matchLabels`/`matchExpressions` are fields inside LabelSelector, not directly inside the PVC spec object

just a typo or am i reading this wrong and it’s actually correct?

gorgeous-egg-16927

You’re right, that is a bug. Would you mind filing an issue or contributing a PR?

gifted-beach-2614

11/19/2020, 10:28 PM

i can open a PR, sure - the label selector fields need to be added to the workload resources as well

as a followup, any chance we could get a new provider release cut with this commit?

gorgeous-egg-16927

Yes, I’m expecting to cut a release in the next day or two.

We also publish dev builds, so you could use that in the meantime if you’re blocked
