<p>I have deployed Kubernetes using the link <a href="https://kubernetes.io/docs/tasks/tools/install-kubeadm/" rel="nofollow noreferrer">Kubernetes official page</a></p>

<p>I see that Kubernetes is deployed because in the end i got this</p>

<pre><code>Your Kubernetes master has initialized successfully!

To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  https://kubernetes.io/docs/concepts/cluster-administration/addons/

You can now join any number of machines by running the following on each node
as root:

  kubeadm join 172.16.32.101:6443 --token ma1d4q.qemewtyhkjhe1u9f --discovery-token-ca-cert-hash sha256:408b1fdf7a5ea5f282741db91ebc5aa2823802056ea9da843b8ff52b1daff240
</code></pre>

<p>when i do kubectl get pods it thorws this error </p>

<pre><code># kubectl get pods 
The connection to the server 127.0.0.1:6553 was refused - did you specify the right host or port?
</code></pre>

<p>When I do see the cluster-info it says as follows </p>

<pre><code>kubectl cluster-info 
Kubernetes master is running at https://127.0.0.1:6553
</code></pre>

<p>But when i see the config it shows as follows </p>

<pre><code>apiVersion: v1

<p>Even telnet shows that there is a process running on 6443 but not on 6553 
how can change the port and how can I fix the issue??</p>

<p>Any help would be of great use </p>

<p>Thanks in advance.</p>

<p>I figured out the issue it is because of the firewall in the machine I could join nodes to the cluster once I allowed traffic via port 6443. I didn't fix the issue with this post but for beginners use this <a href="https://www.google.com/url?q=http://www.bogotobogo.com/DevOps/DevOps-Kubernetes-III-Kubernetes-on-Linux-with-kubeadm.php&amp;sa=D&amp;source=hangouts&amp;ust=1530265751951000&amp;usg=AFQjCNHMxjNrFJ7CBGaranLBvKr84_qFrA" rel="nofollow noreferrer">K8's on AWS</a> for a better idea.</p>

<p>Thanks for the help guys...!!!</p>
