<p>I'm new to Kubernetes and I'm struggling with few error. I want to create Kubernetes Cluster on my local system(mac).</p>

<p>My deployment.yaml --</p>

<pre><code>apiVersion: apps/v1

<p>Why I am getting this --</p>

<pre><code>Tolerations:     node.kubernetes.io/not-ready:NoExecute for 300s
                 node.kubernetes.io/unreachable:NoExecute for 300s
</code></pre>

<p>Somebody more experienced than me kindly help</p>

<blockquote>
  <p><strong>Note</strong> Kubernetes automatically adds a toleration for <code>node.kubernetes.io/not-ready</code> and <code>node.kubernetes.io/unreachable</code>. </p>
  
  <p>Kubernetes automatically adds a toleration for
  node.kubernetes.io/not-ready with tolerationSeconds=300 unless the pod
  configuration provided by the user already has a toleration for
  node.kubernetes.io/not-ready. Likewise it adds a toleration for
  node.kubernetes.io/unreachable with tolerationSeconds=300 unless the
  pod configuration provided by the user already has a toleration for
  node.kubernetes.io/unreachable. </p>
  
  <p>These automatically-added tolerations
  ensure that the default pod behavior of remaining bound for 5 minutes
  after one of these problems is detected is maintained.</p>

<p>Read <a href="https://kubernetes.io/docs/concepts/configuration/taint-and-toleration/#taint-based-evictions" rel="noreferrer">Complete details here</a></p>

<p><strong>The following taints are built in</strong>:</p>

<p><code>node.kubernetes.io/not-ready: Node is not ready</code>. This corresponds to the NodeCondition Ready being “False”.</p>

<p><code>node.kubernetes.io/unreachable</code>: Node is unreachable from the node controller. This corresponds to the NodeCondition Ready being “Unknown”.</p>

<p>More as below :</p>

<p><code>node.kubernetes.io/out-of-disk</code>: Node becomes out of disk.</p>

<p><code>node.kubernetes.io/memory-pressure</code>: Node has memory pressure.</p>

<p><code>node.kubernetes.io/disk-pressure</code>: Node has disk pressure.</p>

<p><code>node.kubernetes.io/network-unavailable</code>: Node’s network is unavailable.</p>

<p><code>node.kubernetes.io/unschedulable</code>: Node is unschedulable.</p>

<p><code>node.cloudprovider.kubernetes.io/uninitialized</code>: When the kubelet is started with “external” cloud provider, this taint is set on a node to mark it as unusable. After a controller from the cloud-controller-manager initializes this node, the kubelet removes this taint.</p>
