<div>Hi Sergey,</div>
<div>I agree with your feeling, this is from the Heat Wiki page.</div>
<div>"Heat also endeavours to provide compatibility with the AWS CloudFormation template format, so that many existing CloudFormation templates can be launched on OpenStack."</div>
<div><br>
</div>
<div>Note also, there was another review that attempted implement this, but stalled.</div>

<div dir="ltr">
<div>Hi Heaters,</div>
<div><br>
</div>
<div>On the last IRC meeting we had a question about Support Conditionals spec [1].</div>
<div>Previous attempt for this staff is here [2].</div>
<div>The example of first POC in Heat can be reviewed here [3]</div>
<div><br>
</div>
<div>As I understand we have not had any complete decision about this work.</div>
<div>So I'd like to clarify feelings of community about it. This clarification may be done as answers for two simple questions:</div>
<div> - Why do we want to implement it?</div>
<div> - Why do NOT we want to implement it?</div>
<div><br>
</div>
<div>My personal feeling is:<br>
</div>
<div>- Why do we want to implement it?<br>
</div>
<div> * A lot of users wants to have similar staff.</div>
<div> * It's already presented in AWS, so will be good to have this feature in Heat too.</div>
<div> - Why do NOT we want to implement it?<br>
</div>
<div> * it can be solved with Jinja [4] . However I don't think, that it's really important reason for blocking this work.</div>
<div><br>
</div>
<div>Please share your idea about two questions above.</div>
<div>It should allows us to eventually decide, want we implement it or not.</div>
