I have an app I am trying to move to a new k8s cluster, having a permissions issue when trying to ConfirmSubscription:
"sns confirmation failed. Reason: AuthorizationError: User: arn:aws:sts::-:assumed-role/-/- is not authorized to perform:
SNS:ConfirmSubscription on resource: arn:aws:sns:-:-:topicname
status code: 403, request id: 000d2844-3a3d-5544-922a-7d9e3db07a16"The app was able to execute a confirm subscription in the old cluster, so I assume it's an IAM issue, but the role policy it's assuming is:
{
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"sns:ConfirmSubscription",
"sns:Subscribe"
],
"Effect": "Allow",
"Resource": [
"arn:aws:sns:::*"
]
}
]
}
I haven't been able to diagnose where the IAM issue is.
I was able to get this working by fully qualifying the sns topic to which I wanted to confirm subscription:
{
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"sns:ConfirmSubscription",
"sns:Subscribe"
],
"Effect": "Allow",
"Resource": [
"arn:aws:sns:us-east-1:000000000:full-topic-name-no-wildcard"
]
}
]
}
