    Description

      Hello,

      currently it is not possible to set up a template with spot instances that does not specify a bid price.

      Not setting a price like this:

      Results in this error: "Invalid Spot price specified: null"

      Not setting the "Set bid price" for me results in Jenkins just spinning up a usual ec2 instance without a spot request:

      It is possible to create spot requests in EC2 without setting a bid price. This results in a default bid price matching the on-demand price and behaving otherwise same.
      This is described here: https://aws.amazon.com/de/blogs/compute/new-amazon-ec2-spot-pricing/

      I see here that the used library also shortly mentions the default to be the on-demand price so it is an optional setting: https://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/ec2/model/RequestSpotInstancesRequest.html#setSpotPrice-java.lang.String-

      Is there any reason why this is not yet possible in this plugin?

          This is a legacy issue, the code just wasn't updated to allow this. Only more recently has AWS allowed this behaviour

          Actually the code is correct, you can uncheck the bid price. It should create a spot instance
