I would check if whatever AWS identity you are using has permission to perform the

route53:GetChange

action in the account where you are creating the records.

yup, i enabled all Route53 permissions

Couple of things to check: • Is that enabled on all resources or have you locked it down (as you should) with a resource ARN? • If you did lock it down, make sure the ARN allows for that action to be performed on the ARN mentioned in the error message.

it says:

no identity-based policy allows the route53:GetChang

but the policy is "*" and used to be "route53:*"

I don't know but I would start by comparing the ARN in the error message and the resource ARN in your policy.

oh what the f**k

Perhaps time to read about the GetChange action and see what that ARN is about. It looks specific to Route53 records.

yeah... time to self-educate. sorry about the false alarm and derping by not reading logs

All good. It happens! Glad to see you start with a question on how to do something with Pulumi and then doing it. Good luck with the rest! :)

yup! succeeded with my least access of:

const allowedTargetArns = [
	rootZone.arn,
	"arn:aws:route53:::change/*"
]

const allowedActions = [
	"route53:ChangeResourceRecordSets",
	"route53:GetChange",
	"route53:GetHostedZone",
	"route53:ListHostedZones",
	"route53:ListResourceRecordSets",
]

The

change

ARN format is specific to

GetChange

yeah? If so, you could move that to a separate policy statement instead of clubbing it with other actions. Unless, it needs to apply to all other R53 actions too?

you are right, but will lock things down a bit later 🙂 still in the prototyping process. okay maybe I am sleep deprived or something but this seems really weird. here are my role principals for that allow policy:

"Principal": {
                "AWS": [
                    "arn:aws:iam::REDACTED:user/stagAdmin",
                    "arn:aws:iam::REDACTED:user/prodAdmin",
                ]
            },

now ... when I do "aws sts get-caller-identity", they both match. But when I'm logged into the prodAdmin user and select stack "production", I get:

pulumi:providers:aws (core-infra-cross-acc):
    error: rpc error: code = Unknown desc = 2 errors occurred:
        * unable to validate AWS credentials.
    Details: [{0xc0016ca000 0xc0037432f0}]
    Make sure you have set your AWS region, e.g. `pulumi config set aws:region us-west-2`

Which is related to this:

const sharedAccountProvider = new aws.Provider(pre('cross-acc'), {
    assumeRole: sharedRoleArn.apply(roleArn => {
		console.dir(`roleARN ${roleArn}`)
		return {
			roleArn: roleArn,
			sessionName: pre('cross-acc-session')}
    }),
});

This code works on the staging stack/acc but not prod stack/acc. Does pulumi have any special protections or treatments for stacks named "production" ?
