Hello ~
I am trying to create an eb application using eb cli with Multiple Docker Container. I have an applications running on 2 ports so I need to listen on those ports. I tried your configuration on your .ebextensions/elb-listeners.config but I encounter an error of ERROR: Service:AmazonCloudFormation, Message:Template error: instance of Fn::GetAtt references undefined resource AWSEBLoadBalancer. Below is my configuration.

option_settings:
  aws:elb:listener:8745:
    ListenerProtocol: HTTP
    InstanceProtocol: HTTP
    InstancePort: 8745
  aws:elb:listener:3517:
    ListenerProtocol: HTTP
    InstanceProtocol: HTTP
    InstancePort: 3517

Resources:
  port8745SecurityGroupIngress:
    Type: AWS::EC2::SecurityGroupIngress
    Properties:
      GroupName: {Ref : AWSEBSecurityGroup}
      IpProtocol: tcp
      ToPort: 8745
      FromPort: 8745
      SourceSecurityGroupName: { "Fn::GetAtt": ["AWSEBLoadBalancer", "SourceSecurityGroup.GroupName"] }
      SourceSecurityGroupOwnerId: { "Fn::GetAtt": ["AWSEBLoadBalancer", "SourceSecurityGroup.OwnerAlias"] }
  port3517SecurityGroupIngress:
    Type: AWS::EC2::SecurityGroupIngress
    Properties:
      GroupName: {Ref : AWSEBSecurityGroup}
      IpProtocol: tcp
      ToPort: 3517
      FromPort: 3517
      SourceSecurityGroupName: { "Fn::GetAtt": ["AWSEBLoadBalancer", "SourceSecurityGroup.GroupName"] }
      SourceSecurityGroupOwnerId: { "Fn::GetAtt": ["AWSEBLoadBalancer", "SourceSecurityGroup.OwnerAlias"] }

Do you know where did I miss? I'm a newbie in AWS so sorry for my ignorance. Your help will be much appreciated.

Thanks!
