          Description

          A quick question:

          In a "vars" file in ansible, can you refer to another variable defined in the same file?

          For example, can you do the following?

          var1: hello
          var2: world
          var3: "{{ var1 }} var2"

          That is, what I would like to do is define a variable and then use it to define additional variables elsewhere in a variables file.

          For example, I would like to be able to define "ec2_name" and then re-use it to define the name of the appstore database:

          ec2_name: appstore123
          ...
          rds_db_name: "{{ ec2_name }}"

          Do you know: Is this legal in ansible?

          Asking because you might know the answer off-hand. I have not had much luck searching google for the answer.

          If you don't know it off-hand, just add that as a comment in the ticket. No need to do a lot of deep dive research.

              The above link might help, but how I suggest to do it is don't declare a variable as a combination of 2 vars instead combine the vars where the playbook runs dynamically.

              In our case, we have too many vars currently, I am planning to reduce a few as time progresses. That will make things a bit simple
