I just asked a question about which exceptions to rescue when using  
http\_request. After  
doing some more research, I’ve learned that this question doesn’t really make  
sense…

I’ve read that I can’t catch the Exception at the time the recipe runs.

I have some code that uses Net::HTTP::Get that runs in a lwrp. I am  
able to rescue exceptions  
there. Must I write my own code to do an HTTP post if I need to have  
the run not  
fail just because it can’t post? The post is ideal, but optional…

Brief answer: no, you can use ignore\_failure in any resource to continue the chef run if it fails.

Side option the retry\_count (I think) attribute to let a resource retry its job in case of failure.

The doc about it is somewhere in the common options in [docs.getchef.Com](http://docs.getchef.Com), but on the phone I can't tell right now

Can you back up and explain what you are trying to do?

I have a recipe that does a http\_request to post to a REST api. If  
that api is down I don't want  
the entire run to fail, I just want a log entry and for the run continue.

Look at `ignore_failure` here: [Common Resource Functionality](http://docs.getchef.com/resource_common.html)
