I wanted to create a jenkins pipeline that scans all the docker images in ecr..I have used the list-images command to list all the images and extracted ImageDigests in a ArrayList(arr). But it wouldn't read the value of imageDigest when interpolating it in the sh image-scan command.

    arr.each{x  ->
       sh  '''aws ecr start-image-scan --repository-name databricks --image-id imageDigest="${x}" --region us-east-1   '''                                    
    }

output : aws ecr start-image-scan --repository-name databricks --image-id imageDigest= --region us-east-1

An error occurred (InvalidParameterException) when calling the StartImageScan operation: Invalid parameter at 'imageDigest' failed to satisfy constraint: 'must satisfy regular expression '[a-zA-Z0-9-_+.]+:[a-fA-F0-9]+''

  • What is the value of ${x}? This command works perfectly for me. aws ecr start-image-scan --repository-name my-repo --image-id imageDigest=sha256:blahblah --profile my-profile Commented Aug 16, 2022 at 8:05
  • I had created a ArrayList of all the imageDigests I got from list-image command. x is the value of imageDigest while iterating through the ArrayList Commented Aug 16, 2022 at 11:27
  • I understood that is a array, but your command seem fine for me. Paste the command replacing the x variable for its value. You can truncate or change it but keep the format for an assessment Commented Aug 16, 2022 at 16:26
  • Actually I wanted to scan for each image in this array, as there are multiple images I want to scan..is that possible in a loop? Commented Aug 17, 2022 at 10:18
