hi, you have to find common pattern in the hostnames and forge subregexp in
brakets..
for example if the changing part is the number enclose them in brackets and
backreference them in line as \cardianalnumber
in the example below
\1 will reference to (.*)
\2 will reference to the first (\d+)
\3 will reference to the second (\d+)
\4 will reference to the tailing (.*)
At the moment I can't test the playbook, anyway you try something like
- hosts: localhost
tasks:
- name: lineinfile
lineinfile:
path: ./hosts
regexp: '^(.*)\bserver-rack(\d+)-test-server-(\d+)\b(.*)$'
line: '\1 server-rack\2-test-server-\3.corp.company.com
<http://server.corp.company.com> \4'
backrefs: yes
Have a look at https://docs.python.org/2/library/re.html for further details
regards
Luca
