Terraform how to to set correct IAM permissions for AWS Batch job role despite correct policy attachments
After trying multiple solutions online, I still can't figure this out. I've been researching this but I keep running into I'm reviewing some code and I'm working with an scenario where my Terraform script is not applying the correct IAM permissions for an AWS Batch job role... I've defined an IAM role with a policy that should allow the Batch job to pull images from ECR and write logs to CloudWatch. However, when I run the job, I receive an behavior saying `An behavior occurred (AccessDeniedException) when calling the RegisterJobDefinition operation: User: arn:aws:iam::123456789012:user/test is not authorized to perform: ecs:RegisterTaskDefinition on resource: arn:aws:ecs:us-east-1:123456789012:task-definition/my-task`. I've double-checked my role and policy definitions, but it seems like the permissions are not being applied correctly. Here's the relevant snippet of my Terraform code: ```hcl resource "aws_iam_role" "batch_job_role" { name = "batch_job_role" assume_role_policy = jsonencode({ Version = "2012-10-17" Statement = [ { Action = "sts:AssumeRole" Effect = "Allow" Principal = { Service = "batch.amazonaws.com" } } ] }) } resource "aws_iam_policy" "batch_policy" { name = "batch_policy" policy = jsonencode({ Version = "2012-10-17" Statement = [ { Action = [ "ecr:GetAuthorizationToken", "ecr:BatchCheckLayerAvailability", "ecr:GetDownloadUrlForLayer", "ecr:BatchGetImage", "logs:CreateLogStream", "logs:PutLogEvents" ], Effect = "Allow", Resource = "*" } ] }) } resource "aws_iam_role_policy_attachment" "batch_attach" { policy_arn = aws_iam_policy.batch_policy.arn role = aws_iam_role.batch_job_role.name } resource "aws_batch_job_definition" "my_job" { name = "my_job" type = "container" container_properties = jsonencode({ image: "123456789012.dkr.ecr.us-east-1.amazonaws.com/my-image:latest", vcpus: 1, memory: 1024, jobRoleArn: aws_iam_role.batch_job_role.arn }) } ``` I've applied the Terraform configuration multiple times, and I can see that the role and the policy are created successfully, but it seems like the permission scenario continues. I've also looked into the trust relationships for the IAM role, and everything appears to be set correctly. Am I missing something in my configuration or is there something else that could be causing this scenario? What would be the recommended way to handle this? For reference, this is a production mobile app. I appreciate any insights! I'm working in a Ubuntu 22.04 environment. What would be the recommended way to handle this? Hoping someone can shed some light on this. I'm working with Hcl in a Docker container on Linux. Any feedback is welcome!
