Will support for Dynamic Providers be released for Golang?

How do I get the actual

string

value out of

pulumi.StringOutput

or

pulumi,StringPtrOutput

?

I essentially have a

Params

struct that I use to set the values for a function and I need to get the output into the struct

I am creating a Kubernetes namespace and then I want to create a service account in that namespace.

is there a way to convert an output to an input?

i’m trying to get a value out of the config, get it’s concrete string value using ApplyT, and then use that string value in a text template. i then return that template string in the ApplyT function, and I’d like to use the file contents in a resource

I used the (*pulumi.Context).Export() function to export a pulumi.StringArray of subnet IDs, and a few other metadata. At the bottom is an excerpt of my stack output as stored in my state file, which I’m already able to load using pulumi.NewStackReference(), and read a plain string like the “eip-1”, for example. My code for reading the eip-1 (which works) is:

nsr, _ := pulumi.NewStackReference(ctx, vpcStackRef, nil)
eip1 := nsr.GetStringOutput(pulumi.String("eip-1"))

Now what I can’t figure out is how to read “data-subnets” into a slice. Can anybody help?

"resources": [
                {
                    "urn": "urn:pulumi:dev::vpc::pulumi:pulumi:Stack::dev",
                    "custom": false,
                    "type": "pulumi:pulumi:Stack",
                    "outputs": {
                        "data-subnets": [
                            "subnet-abcddaed530b25d91",
                            "subnet-abcdcfacd0c04fe74",
                            "subnet-abcd693e4a8ae4ca8"
                        ],
                        "eip-1": "eipalloc-abcdcfa5cf063576d"

Hi all, can you point me towards and example on how to create a custom resource in Golang SDK? I want to generate PGP keys. I tried some things with ComponentResource, but the output generation code runs on every

pulumi up

, and the output changes. So I assume I’m using the wrong approach here.

are there any examples for alternatives to a huge main func? for creating a bunch of resources? vpc + eks type things?

This may be due to an error on my part, but I was just running into a problem running

pulumi preview

against one of my stacks (I’ll post the full error output in the thread). This is with Pulumi 3.29.1 on macOS running Go 1.18.1. The fix ended up being upgrading

<http://golang.org/x/sys|golang.org/x/sys>

(via

go get -u <http://golang.org/x/sys|golang.org/x/sys>

), and then

pulumi preview

seemed to work just fine. Posting here in case someone else runs into a similar problem.

Howdy Team, when unit testing. How do you test functions that have parameters? I getting type errors when trying to run tests against my functions. For example, my SQL server function needs information about a vnet, so I pass in a vnet object. When I get to testing, I don't have a vnet object available.

how do you convert a

*string

to a

pulumi.StringPtrInput

?

Hello, following the announcement of multi-language availability for AWS crosswalk, I’m wondering if Go support is already there: when I do a

go get <http://github.com/pulumi/pulumi-awsx/sdk|github.com/pulumi/pulumi-awsx/sdk>

it brings me a strange

v1.0.0-testplsignore.0

version, and when I try a

pulumi up

, I get the following error

Diagnostics:
  pulumi:providers:awsx (default):
    error: no resource plugin 'pulumi-resource-awsx' found in the workspace at version v1.0.0-testplsignore.0 or on your $PATH, install the plugin using `pulumi plugin install resource awsx v1.0.0-testplsignore.0`

This makes me think Go support isn’t ready yet. However, the relase notes talk about Go SDK: https://github.com/pulumi/pulumi-awsx/releases. What’s the current situation?

A constructor (resource A) needs a

*string

but all I can provide is a

pulumi.StringOutput

from resource B. How do I force the resolution of the StringOutput before A is initialized? I do not want to init A inside the

Apply

functions of B's outputs, because that gives me inaccurate previews.

Hi everyone. Trying Pulumi out for the first time using

Go

and

AWS

. Having a weird issue when trying to update a stack containing

EKS

. No matter what changes I add (a new node group or simply adding a Helm chart) an

EKS cluster replace

is always included in the changes. Is there something obvious Im missing? Thank you!

Hello, trying to create an EKS cluster with a managed node group using EKS crosswalk for AWS, I get a strange error which doesn’t speak to me. Here is the code

cluster, err := eks.NewCluster(ctx, "test",
	&eks.ClusterArgs{
		ProviderCredentialOpts: &eks.KubeconfigOptionsArgs{
			RoleArn: pulumi.String("<arn>"),
		},
		CreateOidcProvider:   pulumi.Bool(true),
		SkipDefaultNodeGroup: pulumi.Bool(true),
	},
)
if err != nil {
	return fmt.Errorf("failed to create EKS cluster: %w", err)
}

_, err = eks.NewManagedNodeGroup(ctx, "ng1",
	&eks.ManagedNodeGroupArgs{
		Cluster: cluster.Core,
	},
)
if err != nil {
	return fmt.Errorf("failed to create EKS managed node group: %w", err)
}

and here is the error

Previewing update (test):

Do you know what this error means? Should I post this message in #aws instead?

Hello, I’m trying to use the Kubernetes Provider of my EKS Cluster (field Provider on the Cluster type https://pkg.go.dev/github.com/pulumi/pulumi-eks/sdk/go/eks#Cluster) to create resources in this cluster. However, I don’t know how to use it. I cannot just pass

pulumi.Provider(cluster.Provider)

as a resource option on a

NewNamespace()

call as its type is

kubernetes.ProviderOutput

which doesn’t seem to be compatible with

pulumi.ProviderResource

. Any idea?

Hi there 🙂! I’m trying to use config.RequireObject to load configuration into my struct. When I try to run a simple integration test, it panics, as it always says I haven’t set the configuration variables (even though I see them being set in the test). Am I understanding the functionality wrong? My expectation is that when provided no namespace, it uses the default one (in my example it is

pulumi-project-name

), I then provide RequireObject the key of the object I want to load from configuration (in my example

stack

), and it should deserialise it accordingly.

import (
	"<http://github.com/pulumi/pulumi/pkg/v3/testing/integration|github.com/pulumi/pulumi/pkg/v3/testing/integration>"
	"<http://github.com/pulumi/pulumi/sdk/v3/go/pulumi|github.com/pulumi/pulumi/sdk/v3/go/pulumi>"
	"os"
	"testing"
)

type Configuration struct {
	Project string
	Region
	Ephemeral bool
}

type Region struct {
	LongName  string
	ShortName string
}

//	Pulumi.test.yaml
// 	encryptionsalt: ...........

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {

	})
}

}

Is there a way to use a stack transformation to tag all AWS (actually

aws-native

) resources in Golang? I have a real hard time to figure out how to do this (see all the

???

in below example). The main problem is that

aws-native

uses no common (shared) types for tags and sets of tags, instead it uses generated

interface

types specific to each taggable resource.

package aws

import (
	"fmt"
	"reflect"
	"strings"

	"<http://github.com/pulumi/pulumi/sdk/v3/go/pulumi|github.com/pulumi/pulumi/sdk/v3/go/pulumi>"
)

type Tagger struct {
	tags map[string]string
}

func NewTagger() *Tagger {
	return &Tagger{}
}

func (*Tagger) isTaggable(ctx *pulumi.Context, typeName string, t reflect.Type) bool {
	if strings.HasPrefix(typeName, "aws-native:") {
		if field, found := t.FieldByName("Tags"); found {
			switch field.Type.Kind() {
			case reflect.Slice:
				return true
			}
		}
	}
	return false
}

func (t *Tagger) Apply(ctx *pulumi.Context) error {
	return ctx.RegisterStackTransformation(
		func(args *pulumi.ResourceTransformationArgs) *pulumi.ResourceTransformationResult {
			if t.isTaggable(ctx, args.Type, args.Props.ElementType()) {
				ptr := reflect.ValueOf(args.Props)
				val := ptr.Elem()
				tags := val.FieldByName("Tags")
				var tagList ???
				if !tags.IsZero() {
					tagList = tags.Interface().(???)
				} else {
					tagList = ???{}
				}
				for k, v := range t.tags {
					tagList = append(tagList, ???{ Key: pulumi.String(k), Value: pulumi.String(v)})
				}
				tags.Set(reflect.ValueOf(tagList))
				return &pulumi.ResourceTransformationResult{
					Props: args.Props,
					Opts:  args.Opts,
				}
			}
			ctx.Log.Warn(fmt.Sprintf("isTaggable(%s) -> false", args.Type), nil)
			return nil
		},
	)
}

Hey all! 👋 I'm currently hitting this bug on a new stack: https://github.com/pulumi/pulumi-docker/issues/320 Does anyone have a workaround? Here's my

main.go

file if helpful:

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		// Build the container image
		image, err := docker.NewImage(ctx, "trustified-api", &docker.ImageArgs{
			Build: &docker.DockerBuildArgs{
				Context:    pulumi.String("../"),
				Dockerfile: pulumi.String("dev.Dockerfile"),
			},
			ImageName: pulumi.String("trustified-api:dev"),
			SkipPush:  pulumi.Bool(true),
		})
		if err != nil {
			fmt.Printf("Error building image: %s", err.Error())
		}
		ctx.Export("baseImageName", image.BaseImageName)
		ctx.Export("fullImageName", image.ImageName)
		return nil
	})
}

Hi, I’m looking for some docs and unable to find them. I’m hoping someone can point me in the right direction. I’m trying to launch a docker container in a network. I’ve created the network:

network, err := docker.NewNetwork(ctx, "trustified", &docker.NetworkArgs{
   Attachable: pulumi.Bool(true),
   Name:       pulumi.String("trustified-" + stack),
})

And now trying to launch a container in that network, but I’m not certain what to put in the “NetworksAdvanced” field. It seems like my network var should be the right thing but it errors because networks doesn’t implement ContainerNetworksAdvancedArrayInput. Here’s the code I’m using:

apiContainer, err := docker.NewContainer(ctx, "api", &docker.ContainerArgs{
   Envs:             pulumi.ToStringArray(apiEnvVars),
   Healthcheck:      nil,
   Image:            api.ImageName,
   Name:             pulumi.String("api"),
   NetworksAdvanced: network,
   Ports:            nil,
   Volumes:          nil,
})

How do I transform the network I created to a ContainerNetworksAdvancedArrayInput type?

Hi Does anyone know if it's possible to get the command that was run within my application? I'm adding some telemetry to track deployments etc and I'd like to know if someone ran

pulumi up

or

pulumi preview

Hi, I am looking to create an Aurora serverless V2 cluster for AWS Postgres DB using Pulumi golang API. I see https://github.com/pulumi/pulumi-aws/issues/1929 referencing a Terraform update, when will this be supported in the golang API?

Is there any chance there's a golang version of this example: https://github.com/pulumi/pulumi-eks/blob/f60263061a85d2817ecd0fd4c3dbc6505e4a8df9/examples/oidc-iam-sa/index.ts#L37-L51 I'm struggling to translate this functionality to my code.

Is there a good place I can go to learn more about good patterns and practices when working with Pulumi in golang?

Help with AWS IAM policies. Hi everyone! I’m a bit stuck with IAM policy creation using pulumi AWS. The policy document as described here should be a string, however, if you want to restrict it to a specific resource you created before you need to convert resource ARN to a string. I looked into the examples in the doc but they are not very helpful with that. What are the options here to pass the resource ARN you created to a policy document (or in other words convert

pulumi.StringOutput

to

string

)?

https://www.pulumi.com/registry/packages/gcp/api-docs/provider/ how do I use the

google-beta

provider? The syntax in the documentation seems off from what I actually need. EDIT: The documentation here helped me get the correct syntax down. https://www.pulumi.com/docs/intro/concepts/resources/providers/ Anyone know where I can report this documentation discrepancy?

regarding the aws-native library; is there a generic tags interface? It looks like with AWS classic you can feed a

pulumi.Map{}

for tags, but with native each resource has its own type

Hi, I’m a bit lost with the RouteTable function. I’m trying to create a RouteTable and I’m getting

""

as a CidrBlock. Not sure why. This is my code:

routeTable, err := ec2.NewRouteTable(ctx, n.genUniqName("route-private", i), &ec2.RouteTableArgs{
			VpcId: n.VPC.ID(),
			Routes: ec2.RouteTableRouteArray{
				&ec2.RouteTableRouteArgs{
					CidrBlock: subnet.CidrBlock

and

subnet.CidrBlock

is from

[]*ec2.Subnet

. When I’m doing

fmt.Println()

on it, I see

{0xc0003c93b0}

.
