I'm writing a program that creates instances of EC2 on AWS. The names of the instances are "Manager" and "Worker", and for some unknown reason, in some of the runs, an instance with the name "-" is created (just a dash). Has anyone experienced something similar?

It's difficult to say exactly why this might be happening without more information about your program, such as the specific code you're using to create the EC2 instances and the configuration settings you're using. It's possible that you're inadvertently using a default value for the instance name that includes a dash, or that there is a bug in your code that is causing this behavior.

In general, when creating EC2 instances on AWS, you should specify a unique name for each instance to avoid conflicts and make it easier to manage your instances. If you're not sure why a dash is being used as the instance name in your program, I would recommend reviewing your code and configuration settings to see if you can identify the cause of the problem. Additionally, it might be helpful to check the AWS documentation for guidance on creating EC2 instances and specifying their names.

The - is just the AWS Web console's way of indicating that no name has been specified for this EC2 instance. Names are optional on EC2 instances, and on this particular instance you haven't specified name. Names are specified on EC2 instances by adding a tag, with the key of Name and value of whatever you want the name to be.
