Waiting for host name to be resolvable

[Yaroslav Tkachenko]

Hey guys,

I'm writing very simple task - I have a web app that I start and it takes a few minutes before it goes online. I thought it can be done like this:

- name: Waiting for the new environment to be online

  uri: url=http://SOME_URL/api/heartbeat timeout=900

  async: 900

  poll: 10

But the problem is: SOME_URL is not resolvable instantly, it's a new DNS record. So task fails with the error "msg: Unable to resolve the host name given.". 

Is there any way to solve this issue? 

Thanks!

How is the DNS record created?

How about wait_for?

- wait_for: host=SOME_URL port=80 delay=20 state=started

It fits this situation perfectly because wait_for will keep trying to
resolve the DNS name over and over (and not just once when it starts).

Regarding the application itself being up, let me suggest a subsequent
check with get_url module (this one doesn't keep trying to resolve the
hostname many times, so wait_for is really required).
