You see examples of people using etcd, zookeeper, consul and so on. I recently had a project to migrate some solr clusters to docker and I started looking at some of those tools and how they would fit that our current infrastructure.</p> <p>After some researching I found that the KISS way of doing service discovery on our environment was to use route53. The main reasons for this decision were:</p>Ansible: Data structure handling and transformationhttps://felisbino.dev/posts/ansible-data-structures/Fri, 02 Sep 2016 00:00:00 +0000Filipe Felisbinohttps://felisbino.dev/posts/ansible-data-structures/From time to time I had some dificulties with handling data structures with ansible. Things like converting a list of dicts to a list of values ( inside a dict ) or even filtering a list aren’t always trivial.

Because of that, I’ve written a small filter plugin called json_query, that allows you to do some cool transformations with ansible. The filter uses jmespath ( http://jmespath.org/ ) a query language for json data. The plugin is already merged to devel branch and will be released on 2.2 version of ansible.
