AWS EKS Cluster how to to Pull Docker Images from Private ECR with IAM Roles for Service Accounts
I've been struggling with this for a few days now and could really use some help. I'm stuck on something that should probably be simple. I've been working on this all day and I'm relatively new to this, so bear with me... I've looked through the documentation and I'm still confused about I'm stuck on something that should probably be simple. I'm working with an scenario where my Amazon EKS cluster is unable to pull Docker images from a private ECR repository. I have configured IAM Roles for Service Accounts (IRSA) to grant permissions to my pod, but it still fails with the behavior message: `behavior: ImagePullBackOff`. I've verified that the ECR permissions are set correctly in the IAM policy. Here is the relevant configuration: ```yaml apiVersion: v1 kind: ServiceAccount metadata: name: my-service-account namespace: my-namespace annotations: eks.amazonaws.com/role-arn: arn:aws:iam::123456789012:role/myEKSServiceAccountRole --- apiVersion: batch/v1 kind: Job metadata: name: my-job namespace: my-namespace spec: template: spec: serviceAccountName: my-service-account containers: - name: my-container image: 123456789012.dkr.ecr.us-west-2.amazonaws.com/my-private-repo:latest restartPolicy: Never ``` I have also attached the policy to the role that the service account uses, and it looks like this: ```json { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "ecr:GetAuthorizationToken", "ecr:BatchCheckLayerAvailability", "ecr:GetDownloadUrlForLayer", "ecr:BatchGetImage" ], "Resource": "*" } ] } ``` I've confirmed that kubectl can connect to EKS and that I can manually push/pull images using the AWS CLI with the same IAM role. The cluster is running EKS version 1.21, and I believe I'm following the IRSA best practices. However, the pods still unexpected result to start due to the image pull scenario. Is there something I'm missing in the configuration, or could it be an scenario with the EKS setup itself? For context: I'm using Yaml on Linux. What's the best practice here? For context: I'm using Yaml on Windows. I'd really appreciate any guidance on this. I'd love to hear your thoughts on this. I've been using Yaml for about a year now. What am I doing wrong? The stack includes Yaml and several other technologies.
