A Spring Cloud application operates by creating a &#8220;bootstrap&#8221; context, which is a parent context for the main application.
It is responsible for loading configuration properties from the external sources and for decrypting properties in the local external configuration files.
The two contexts share an <code class="literal">Environment</code>, which is the source of external properties for any Spring application.
By default, bootstrap properties are added with high precedence, so they cannot be overridden by local configuration.</p><p>The bootstrap context uses a different convention for locating external configuration than the main application context.
By default, bootstrap properties (not <code class="literal">bootstrap.properties</code> but properties that are loaded during the bootstrap phase) are added with high precedence, so they cannot be overridden by local configuration.</p><p>The bootstrap context uses a different convention for locating external configuration than the main application context.
Instead of <code class="literal">application.yml</code> (or <code class="literal">.properties</code>), you can use <code class="literal">bootstrap.yml</code>, keeping the external configuration for bootstrap and main context
nicely separate.
The following listing shows an example:</p><p><b>bootstrap.yml.&nbsp;</b>
