I have:

`

- debug: var=\_consul\_install\_agent
- debug: var=consul\_use\_dnsmasq
- debug: msg=“{{\_consul\_install\_agent and consul\_use\_dnsmasq}}”

`

The two variables are true and false respectively, but the expression evaluates to true?

`  
TASK: [consul | debug var=\_consul\_install\_agent] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
ok: [10.0.196.112] =\> {  
“var”: {  
“\_consul\_install\_agent”: “False”  
}  
}

TASK: [consul | debug var=consul\_use\_dnsmasq] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
ok: [10.0.196.112] =\> {  
“var”: {  
“consul\_use\_dnsmasq”: “True”  
}  
}

TASK: [consul | debug msg=“{{\_consul\_install\_agent and consul\_use\_dnsmasq}}”] \*\*\*  
ok: [10.0.196.112] =\> {  
“msg”: “True”  
}

`

But if the expression is

`

- debug: msg=“{{\_consul\_install\_agent == true and consul\_use\_dnsmasq == true}}”  
`

Then it evals to false.

Is this expected with jinja? Without the ‘and’ the ‘== true’ seems not necessary.

There’s a high likelihood that their type is actually ‘string’ instead of boolean, try

- debug: msg=“{{ (\_consul\_install\_agent | bool) and (consult\_use\_dnsmasq | bool) }}”

Indeed. The values were “== **‘True’** ” not “== True”. Thanks!
