Access Denied when calling the CreateInvalidation operation on AWS CLI.

If you are getting access denied when calling the CreateInvalidation operation on AWS CLI, it must be a permission issue for that user. 

In this post, I am using the Jenkins pipeline to build and pushing the artifacts into S3. I am using CloudFront for Content Delivery Network (CDN) and hosting my web site in Route 53. 

When I am trying to do the CloudFront Distribution invalidate the cache from CLI, I am getting this below error. I thought to add some screenshot to get more visibility, so added below.

Error Log:-

A client error (AccessDenied) occurred when calling the CreateInvalidation operation: User: arn:aws:iam::xxxxxxxxxxx:user/yyyy is not authorized to perform: cloudfront:


The below command I am using from AWS CLI :

aws configure set preview.cloudfront true
aws cloudfront create-invalidation --distribution-id UJH89JKKMOVY340 --paths "/*"    



Resolution:-

Add the "CreateInvalidation" permission to that user. Below are the steps to add the permission.


  • Goto Identity and Access Management (IAM) 
  • Goto Users and find your username, here for me its "Jenkins"
  • Then add a new "Add Inline policy", below the screenshot.

  • Now add the below policy into the JSON policy editor. Below the screenshot.

Policy JSON:-


{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditoro",
            "Effect": "Allow",
            "Action": "cloudfront:CreateInvalidation",
            "Resource": "arn:aws:cloudfront::17088938460999:distribution/UJH89JKKMOVY340"
        }
    ]
}


Sample Screenshot:-




Now, it's working fine. I can see the Jenkins logs below.
