<p>I am unable to connect to an exposed IP for a docker container deployed on Google Could Kubernetes. I have been roughly following <a href="https://cloud.google.com/kubernetes-engine/docs/tutorials/hello-app" rel="noreferrer">this tutorial</a> but using my own application.</p>

<p>The deployment seems to work fine, everything is green and running when visiting the cloud dashboard but when trying to visit the deployed application on the exposed IP, I get a browser error:</p>

<blockquote>
  <p>This site can’t be reached
  35.231.27.158 refused to connect</p>
</blockquote>

<p>If I ping the IP I do get a response back.</p>

<p><code>kubectl get pods</code> produces the following:</p>

<pre><code>NAME                        READY     STATUS    RESTARTS   AGE

<p>and <code>kubectl get service</code> shows the following:</p>

<p>and <code>kubectl describe svc</code> show the following:</p>

<p>My <code>Dockerfile</code> contains the following:</p>

<pre><code>FROM nginx:alpine

COPY nginx.conf /etc/nginx/nginx.conf

WORKDIR /usr/share/nginx/html

COPY dist/mtg-dash .
</code></pre>

<p>I have a feeling I have missed something obvious. </p>

<p><strong>What more do I need to do to configure this to be accessible on the internet?</strong></p>

<p>Here is a screenshot of running service:</p>

wper
<p>As per the comments the target port should be 80 since that is what the application is set to listen on. Glad I could help. Picked it up from the documentation a month or so ago.</p>
