Upload to S3 not working (v6.6.0 (5c11bbdfb4))

Grafana
1

Hi, ive read through all the other issues in the forum, and beleive I have everything configured correctly.

I’m running Grafana within an AWS VPC (the subnet has access to the internet as i have datasources being read over the inernet), and i’m attempting to get Slack alerts working with Images. My set up is using instance IAM profile below rather than secret and access keys.

Running from Docker

-e GF_LOG_LEVEL=debug
-e GF_EXTERNAL_IMAGE_STORAGE_PROVIDER=s3
-e GF_EXTERNAL_IMAGE_STORAGE_S3_BUCKET=fake-bucket-name
-e GF_EXTERNAL_IMAGE_STORAGE_S3_REGION=eu-west-2

When i fire an alert, i see the alert in Slack, but no image attached. And no image within the S3 bucket.

The logs show:

t=2020-01-29T14:43:34+0000 lvl=dbug msg="Image rendered" logger=rendering renderer=phantomJS path=/var/lib/grafana/png/89dYVhxBBFOgYrdTyhx4.png

My IAM profile is:

{
“Version”: “2012-10-17”,
“Statement”: [
{
“Action”: [
“s3:ListBucket”
],
“Resource”: [
“arn:aws:s3:::fake-bucket-name”
],
“Effect”: “Allow”,
“Sid”: “AllowListGrafanaImages”
},
{
“Action”: [
“s3:PutObject”,
“s3:PutObjectAcl”,
“s3:GetObject”,
“s3:DeleteObject”
],
“Resource”: [
“arn:aws:s3:::fake-bucket-name/*”
],
“Effect”: “Allow”,
“Sid”: “AllowGrafanaAlertImages”
}
]
}

Any help appreciated.

Thanks
