Replace text using saltstack - jinja2

Question

I will need your assistance on the following:
I would like to replace an IP address within a file, regex is matching, but the output is totally wrong.
test.sls
wsc_start_server:
file.managed:
- name: /tmp/modify.txt
- source: salt://modify.txt
{% set ip = grains['fqdn_ip4'] %}
wsc_jbos_replace_hostname:
file.replace:
- name: /tmp/modify.txt
- pattern: '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'
- repl: {{ ip }}
- backup: '.bak'
- show_changes: True
modify.txt
address=y.y.y.y
address.private=y.y.y.y
salt 'workstation' state.apply test.sls
output:
address=['x.x.x.x']
address.private=['x.x.x.x']
When I am running the state why I am getting the ip address in ['x.x.x.x'] format instead of address=x.x.x.x ????
Note: y.y.y.y & x.x.x.x are IP Addresses

Answer 1

The issue is that the fqdn represent a list.
to fix the issue I change the following:
{% set ip = grains['fqdn_ip4'] %}
wsc_jbos_replace_hostname:
file.replace:
- name: /tmp/modify.txt
- pattern: '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'
- repl: {{ ip }}
- backup: '.bak'
- show_changes: True
to the correct one:
{% set ip = grains['fqdn_ip4'][0] %}
wsc_jbos_replace_hostname:
file.replace:
- name: /tmp/modify.txt
- pattern: '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'
- repl: {{ ip }}
- backup: '.bak'
- show_changes: True
it worked. :) :)
