I have an AWS Elastic Beanstalk Rails app that I am configuring via the config script to pull some files from an S3 bucket. When I start up the application, I keep receiving the following error in the logs (bucket name has been changed for security):
Failed to retrieve https://s3.amazonaws.com/my.bucket/bootstrap.sh: HTTP Error 403 : <?xml version="1.0" encoding="UTF-8"?>
<Error><Code>AccessDenied</Code><Message>Access Denied</Message>
Config file:
packages:
yum:
git: []
files:
/opt/elasticbeanstalk/hooks/appdeploy/pre/01a_bootstrap.sh:
mode: "00755"
owner: root
group: root
source: https://s3.amazonaws.com/my.bucket/bootstrap.sh
The Elastic Beanstalk environment is setup with the aws-elasticbeanstalk-ec2-role
IAM role as it's instance role. This role has the following policy:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"s3:Get*",
"s3:List*"
],
"Resource": "arn:aws:s3:::my.bucket/*"
}
]
}
And the S3 bucket has the following policy:
{
"Version": "2008-10-17",
"Statement": [
{
"Sid": "Stmt1371012493903",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::<account #>:role/aws-elasticbeanstalk-ec2-role"
},
"Action": [
"s3:List*",
"s3:Get*"
],
"Resource": "arn:aws:s3:::my.bucket/*"
}
]
}
What do I need to change to give my EC2 instances access to my S3 bucket?
