Hey guys,

I use the following template file .j2 to update config file on remote host.

Template file: pg\_hba.conf.j2

{% for slave in groups[‘slaves’] %}  
host replication {{ [postgresql\_streaming\_user.name](http://postgresql_streaming_user.name) }} {{ hostvars[slave]**[‘ansible\_all\_ipv4\_addresses’]** }}/32 {{ postgresql\_default\_ipv4\_auth\_method }}  
{% endfor %}

Configuration file: pg\_hba.conf.j2

host database user **[u’10.123.214.7’]**/32 md5

How I can adapt my template file to remove this character in my configuration file **[u’ ……** **'] ?**

Thanks in advance.

If the server just have one IP you probably should use  
ansible\_default\_ipv4.address instead if ansible\_all\_ipv4\_addresses.

If the server have multiple IP that you would like to include you would need to loop over ansible\_all\_ipv4\_addresses since it is a list of all IP on the server.

Solution looks like this : [‘ansible\_default\_ipv4’][‘address’]
