阅读更多关于 How can I use default with variable in Ansible?

How can I take a list of server names and append a resource URI and port to each?

阅读更多关于 How can I take a list of server names and append a resource URI and port to each?

I merged two lists from an Ansible inventory: set_fact: fact1: "{{ groups['group1'] + groups[group2']|list }} The output is: fact1: - server01 - server02 - server03 With the above results, I need to append https:// to the front, and a port number to the back of each element. Then I need to convert it to a comma delimited list for a server config. In this example I want: https://server01:8000,https://server02:8000,https://server03:8000 . I tried using a join: set_fact: fact2: "{{ fact1|join(':8000,') }}" which partly worked but it left the last server without a port. How can I achieve my goal?
