I'm creating a bucket and a bucket policy using Pulumi / Python. How to get the bucket arn from a bucket resource for creating the bucket policy? If I try to get the bucket arn in the same

pulumi up

run (i.e. creating the bucket and bucket policy) I get

required field is not set

.

You’re getting the error trying access

bucket.arn

with something like:

import pulumi
import pulumi_aws as aws

bucket = aws.s3.Bucket("newBucket")

Maybe try

bucket.id

instead?

@quiet-painter-30539 I provided some guidance at https://pulumi-community.slack.com/archives/CDE799L1M/p1593538890154200?thread_ts=1593508913.150500&cid=CDE799L1M.

I found a way to do it yesterday:

policy = bucket.id.apply(lambda id:
            '''
            {{
...
               "Resource": "arn:aws:s3:::{my_id}/*"
...
'''.format(my_id=id)...
