<p>all service created successfully but give this error message:</p>

<pre><code>Readiness probe failed: Get http://172.30.224.17:8081/actuator/health: dial tcp 172.30.224.17:8081: connect: connection refused
Back-off restarting failed container
</code></pre>

<p>The management port should be the same with eureka service port? what exactly I would do to implement probe service?</p>

Dolphin
<p>Eureka server is a spring boot application which starts an embedded tomcat and you specify the port in the application.yml of the eureka server. The default port is set to 8761.You can use the 8761 port for probe and that's what I would recommend. You need to have a rest endpoint at <code>actuator/health</code> which returns <code>200 Ok</code> which I believe added by spring actuator by default so you don't need to implement it yourself.</p>

<p>In short changing the port from 8081 to 8761 in your probe should work.</p>
