Troubleshooting ECR Access Denied Errors with AWS CLI

If you receive an AccessDeniedException when trying to use AWS CLI commands for ECR operations (such as get-login-password), there are a few common causes and solutions to check: Check User Permissions Verify that the user is not set as "Read Only" in their user settings. Read-only users have limited permissions that may prevent ECR operations. If the user is marked as read-only, an administrator will need to remove this restriction. Verify Required Policies Ensure that the necessary ECR permissions are included in your IAM policies: ecr:GetAuthorizationToken Get* and List* permissions for ECR operations Note: Administrator users typically have broader access permissions than regular users. If an administrator can perform an ECR operation but other users cannot, it's likely a permissions issue that needs to be addressed at the policy level. Common Solutions Have an administrator verify and update the necessary IAM policies to include ECR permissions Check that all policy changes have been properly merged and applied through your infrastructure as code (e.g., Terraform) Ensure cross-account permissions are properly configured if working with ECR repositories in different accounts
