Appveyor cannot upload to S3

Question

I've got a S3 access key and secret set up. I've tried the credentials locally with the aws cli program. However, when run on Appveyor it got permission denied as follows

Deploying using S3 provider Uploading artifact "NOpenType/bin/Release/NOpenType.0.1.4-ci0187.nupkg" (25,708 bytes) to S3 bucket "nrasterizer-artifacts" as "master/NOpenType/bin/Release/NOpenType.0.1.4-ci0187.nupkg" Access Denied

How do I resolve this and let appveyor upload to my bucket?

Answer 1

This could be due to any number of reasons

1. Is S3 provider properly configured? Obvious, but please recheck the key& secret and bucket names etc.
2. Does the user have appropriate permissions? You did mention that you tested the credentials locally. But it could be that there is a S3 bucket policy which restricts uploads etc. to a set to specific IP addresses.

Answer 2

As I was using set_public: true setting I needed the s3:PutObjectAcl permission in addition to s3:PutObject.
