I was struggling with this, too, but I found an answer over here https://stackoverflow.com/a/17162973/1750869 that helped resolve this issue for me. Reposting answer below.
You don't have to open permissions to everyone. Use the below Bucket policies on source and destination for copying from a bucket in one account to another using an IAM user
Bucket to Copy from – SourceBucket
Bucket to Copy to – DestinationBucket
Source AWS Account ID - XXXX–XXXX-XXXX
Source IAM User - src–iam-user
The below policy means – the IAM user - XXXX–XXXX-XXXX:src–iam-user has s3:ListBucket and s3:GetObject privileges on SourceBucket/* and s3:ListBucket and s3:PutObject privileges on DestinationBucket/*
On the SourceBucket the policy should be like:
{
"Id": "Policy1357935677554",
"Statement": [
{
"Sid": "Stmt1357935647218",
"Action": [
"s3:ListBucket"
],
"Effect": "Allow",
"Resource": "arn:aws:s3:::SourceBucket",
"Principal": {"AWS": "arn:aws:iam::XXXXXXXXXXXX:user/src–iam-user"}
},
{
"Sid": "Stmt1357935676138",
"Action": ["s3:GetObject"],
"Effect": "Allow",
"Resource": "arn:aws:s3::: SourceBucket/*",
"Principal": {"AWS": "arn:aws:iam::XXXXXXXXXXXX:user/src–iam-user"}
}
]
}
On the DestinationBucket the policy should be:
{
"Id": "Policy1357935677554",
"Statement": [
{
"Sid": "Stmt1357935647218",
"Action": [
"s3:ListBucket"
],
"Effect": "Allow",
"Resource": "arn:aws:s3::: DestinationBucket",
"Principal": {"AWS": "arn:aws:iam::XXXXXXXXXXXX:user/src–iam-user"}
},
{
"Sid": "Stmt1357935676138",
"Action": ["s3:PutObject"],
"Effect": "Allow",
"Resource": "arn:aws:s3::: DestinationBucket/*",
"Principal": {"AWS": "arn:aws:iam::XXXXXXXXXXXX:user/src–iam-user"}
}
]
}
command to be run is s3cmd cp s3://SourceBucket/File1 s3://DestinationBucket/File1
It is indeed strange, but it appears that the CreateDBSnapshot
permission also has to be assigned to the destination snapshot.
This policy works:
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Stmtxxxxxxxxxxxxxx",
"Effect": "Allow",
"Action": [
"rds:CreateDBSnapshot"
],
"Resource": [
"arn:aws:rds:eu-west-1:xxxxxxxxxxxxxx:db:my-database",
"arn:aws:rds:eu-west-1:xxxxxxxxxxxxxx:snapshot:*"
]
}
]
}

You need to use the
events
servicedelete-rule
subcommand:You need to also make sure you have deleted any of the event's targets with
events remove-targets
.
