<p>I try to run an mongodb inside an kubernetes cluster which is hosted on azure aks</p>

<p>I was not able to get it running, following this tutorial: <a href="https://kubernetes.io/blog/2017/01/running-mongodb-on-kubernetes-with-statefulsets/" rel="nofollow noreferrer">https://kubernetes.io/blog/2017/01/running-mongodb-on-kubernetes-with-statefulsets/</a></p>

<p>here is the yaml I use:</p>

<pre><code>apiVersion: rbac.authorization.k8s.io/v1beta1

<p>The connection string I use is:</p>

<p>"mongodb://mongo-0.mongo,mongo-1.mongo:27017/databasename\_?"</p>

<p>from my JS application I get: </p>

<blockquote>
  <p>database names cannot contain the character '\'</p>
</blockquote>

<p>How I can connect from the JS application to the mongodb?</p>

<blockquote>
  <p>mongodb://mongo-0.mongo,mongo-1.mongo:27017</p>
</blockquote>

<p>You are indicating that you have a replicaset with 2 members and both use the port 27017. Your mongodb library will handle that url to connect to the cluster.</p>

<p>In order to connect locally you have to do a port forwarding:</p>

<blockquote>
  <p>kubectl port-forward mongo-0 27017 # or mongo-1</p>
</blockquote>

<p>Then you can connect to the chosen mongodb with <strong>Robo 3T</strong> using your localhost (127.0.0.1) and the port 27017.</p>
