Looks like the

Role

argument should be

Role.ARN()

aloof-tailor-93191

09/20/2018, 5:42 PM

needed to pass the arn, not the name of the role

aloof-tailor-93191

09/20/2018, 5:42 PM

yeah

incalculable-sundown-82514

09/20/2018, 5:42 PM

yeah

we get to play some tricks in JS that make it harder to make that mistake (you can pass the actual

Role

object in and we grab the ARN from it)

now getting this:``` error: Plan apply failed: creating urn😛ulumi:billing-dev::billing::aws:lambda/function:Function:😒lacker: Error creating Lambda function: InvalidParameterValueException: Uploaded file must be a non-empty zip ```

I tried

asset.NewFileArchive("./function")

and

asset.NewFileArchive("./function.zip")

hmm.

incalculable-sundown-82514

09/20/2018, 5:47 PM

so the only thing the Go SDK has to do is pass a filename to the engine

incalculable-sundown-82514

09/20/2018, 5:47 PM

maybe the Go program is running with a strange working directory?

aloof-tailor-93191

09/20/2018, 5:51 PM

I think it's finding the file ok

aloof-tailor-93191

09/20/2018, 5:52 PM

if I use an invalid path (like 'fun.zip'), it errors out:

marshaling properties: awaiting input property endpoint: rpc error: code = Unknown desc = failed to compute archive hash: open ./fun.zip: no such file or directory

incalculable-sundown-82514

09/20/2018, 5:52 PM

ah, I see

incalculable-sundown-82514

09/20/2018, 5:52 PM

that’s strange

aloof-tailor-93191

I'm able to work around it for the time being by uploading the code to S3 and using that instead of local code

awesome, I got estimated billing notification to slack working, all created with Pulumi (go)

all along the way, the error messages were very helpful

aloof-tailor-93191

09/20/2018, 6:56 PM

I got quite a few as I learned the API

aloof-tailor-93191

09/20/2018, 6:57 PM

and then supplied the wrong values and AWS rejected me with helpful messages too

one thing I ran into was adding DependsOn to the lambda

incalculable-sundown-82514

09/20/2018, 8:43 PM

awesome!

aloof-tailor-93191

09/20/2018, 8:43 PM

lambdaFunction, err := lambda.NewFunction(ctx, "slacker", &lambda.FunctionArgs{
		Runtime: "python3.6",
		S3Bucket: "code-123123123",
		S3Key:    "function.zip",
		Timeout:  300,
		Handler:  "function.lambda_handler",
		Role:     lambdaRole.Arn(),
	}, pulumi.ResourceOpt{
		DependsOn: []pulumi.Resource{policyAttachment},
	})

aloof-tailor-93191

09/20/2018, 8:43 PM

that gives a compile err:

./main.go:107:32: cannot use policyAttachment (type *iam.RolePolicyAttachment) as type pulumi.Resource in array or slice literal:
        *iam.RolePolicyAttachment does not implement pulumi.Resource (wrong type for URN method)
                have URN() *pulumi.URNOutput
                want URN() pulumi.URN

aloof-tailor-93191

09/20/2018, 8:43 PM

I'm guessing there's work to be done on matching up the types?

incalculable-sundown-82514

09/20/2018, 8:46 PM

hmm, that’s unfortunate. that looks like a bug in tfgen (github.com/pulumi/pulumi-terraform)

incalculable-sundown-82514

09/20/2018, 8:46 PM

can you open a bug on that?

aloof-tailor-93191

09/20/2018, 8:46 PM

yes

incalculable-sundown-82514

09/20/2018, 8:47 PM

iam.RolePolicyAttachment

should definitely implement

pulumi.Resource
