Only execute task then certain URL is NOT reachable

[guenthe...@smarter-ecommerce.com]

Hi, 

I have a setup with Apache Mesos and Marathon. 

I also deploy a Elasticsearch with JSON to the Mesos Cluster via Ansible.

But this should only be done, when a certain endpont http://mesos...:8080/v2/apps/elasticserach

is NOT reachable. That indicates, that the module is already (or isn't) installed.

How can I do that in my main.yml?

regards

guenther

The principle is like this.

Use the uri[1] module to check the url and register[2] the output in a
variable.

Use when[3] to check the variable to determine if the task should run or
not.
