Using OpsCenter 5.1.0 and trying to add S3 as a location for snapshot backups. What are the necessary permissions in AWS IAM for the opscenter user? So far, I have the following policy:
"Statement": [
{
"Effect": "Allow",
"Action": [
"s3:ListAllMyBuckets",
"s3:GetBucketLocation"
],
"Resource": "arn:aws:s3:::*"
},
{
"Effect": "Allow",
"Action": [
"s3:ListBucket",
"s3:GetBucketLocation"
],
"Resource": [
"arn:aws:s3:::cassandra-bkup"
]
},
{
"Effect": "Allow",
"Action": [
"s3:DeleteObject",
"s3:GetObject",
"s3:PutObject"
],
"Resource": [
"arn:aws:s3:::cassandra-bkup/*"
]
}
]
but backups are still failing. In opscenterd.log, the following error is seen:
WARN: Marking request af93899e-ae89-4ada-8b3b-ef93d0272d61 as failed: {'sstables': {'reporting_test': {u'cards': {'total_size': 9829, 'total_files': 6, 'done_files': 0, 'errors': [u'{:cause :unknown-destination-provider, :message "Specified provider unknown."}', u'{:cause :unknown-destination-provider, :message "Specified provider unknown."}', u'{:cause :unknown-destination-provider, :message "Specified provider unknown."}', u'{:cause :unknown-destination-provider, :message "Specified provider unknown."}', u'{:cause :unknown-destination-provider, :message "Specified provider unknown."}', u'{:cause :unknown-destination-provider, :message "Specified provider unknown."}']}, etc, etc.
Backup to local server succeeds, however.
After some trial and error, I found that the following policy worked
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"s3:ListAllMyBuckets",
"s3:GetBucketLocation"
],
"Resource": "arn:aws:s3:::*"
},
{
"Effect": "Allow",
"Action": [
"s3:ListBucket",
"s3:GetBucketLocation",
"s3:GetBucketAcl"
],
"Resource": [
"arn:aws:s3:::prod-bkup"
]
},
{
"Effect": "Allow",
"Action": [
"s3:DeleteObject",
"s3:GetObject",
"s3:PutObject"
],
"Resource": [
"arn:aws:s3:::prod-bkup/*"
]
}
]
}
EDIT: added s3:GetBucketAcl as a required permission
