I need to create new variable from contents of other variables. Currently I\'m using something like this:
- command: echo \"{{ var1 }}-{{ var2 }}-{{ var3 }}\"
Good question. But I think there is no good answer which fits your criteria. The best I can think of is to use an extra vars file.
A task like this:
- include_vars: concat.yml
And in concat.yml you have your definition:
concat.yml
newvar: "{{ var1 }}-{{ var2 }}-{{ var3 }}"
