<p>When the Spring Cloud Dataflow Http-Source app Pod starts on kubernetes notice following two messages in console.</p>

<pre><code>Connect Timeout Exception on Url - http://localhost:8888. 
Could not locate PropertySource: I/O error on GET request for "http://localhost:8888/http-source/default": Connection refused (Connection refused); nested exception is java.net.ConnectException
</code></pre>

<p>How to get this resolved?</p>

<p>If you look carefully, the following message will be logged as a <code>WARN</code> in the logs.</p>

<pre><code>Connect Timeout Exception on Url - http://localhost:8888. 
Could not locate PropertySource: I/O error on GET request for "http://localhost:8888/http-source/default": Connection refused (Connection refused); nested exception is java.net.ConnectException
</code></pre>

<p>You'd see this <code>WARN</code> message for all the apps that we ship, SCDF, and Skipper servers that runs on K8s. This means that the apps, SCDF or Skipper don't have a <code>config-server</code> configured, so it defaults to the default <code>http://localhost:8888</code>. </p>

<p><em>Background</em>: we provide the <code>config-server</code> dependency in all the apps that we ship to help you get started with it quickly.</p>

<p>If you don't use the config-server, that's fine; it will not cause any harm - nothing to worry, however.</p>
