title: What are some concrete use-cases for Consul's Key-Value store?
body: <p>We're considering using Consul's key-value store to enhance our configuration management tool (Ansible, at the moment). We're hoping to use it to solve two related problems:</p>
  
  <ol>
  <li>Preventing scatter: Some items (namely: passwords, certificates etc) are scattered across our configuration files. Updating them requires manual search-and-replace which can be tiresome.</li>
  <li>Ease of update: rather then edit-and-commit configuration changes into git, we could use Consul to store those items that change often. </li>
  </ol>
  
  <p>We're looking for a set of recommendations on how to use/integrate Consul (or similar tools) for dynamic configurations. Naturally, there is no one answer, but a set of useful practices here. I'll provide a few approaches in my answer, but I'd like to hear additional ideas.</p>
