I have defined the variable like below:-

input\_host\_ports:

- 4000:fluent:syslog

- 4500:json:log

- 4800:plain:debuglog

I want to get the render the variables in the jinja2 for loop like below:

tcp {  
port =\> 4000  
codec =\> fluent

type =\> syslog  
}  
tcp {  
port =\> 4500  
codec =\> json {  
charset =\> “ISO-8859-1”  
}

type =\> debuglog  
}

tcp {  
port =\> 4800  
codec =\> plain

type =\> debuglog  
}

Only for the port 4500 - I want the charset and also the output should be exactly in this format and in future I may add new ports if required.

Start by defining your variable as a list of dicts, so you can easily  
iterate over them:

input\_host\_ports:  
&nbsp;&nbsp;- port: 4000  
&nbsp;&nbsp;&nbsp;&nbsp;codec: fluent  
&nbsp;&nbsp;&nbsp;&nbsp;type: syslog  
&nbsp;&nbsp;- port: 5500  
&nbsp;&nbsp;&nbsp;&nbsp;codec: json  
&nbsp;&nbsp;&nbsp;&nbsp;type: debuglog  
&nbsp;&nbsp;&nbsp;&nbsp;charset: ISO-8859-1  
&nbsp;&nbsp;- port: 4800  
&nbsp;&nbsp;&nbsp;&nbsp;codec: plain  
&nbsp;&nbsp;&nbsp;&nbsp;type: debuglog
