<p>I'm developing <a href="https://github.com/msrumon/microservice-architecture" rel="nofollow noreferrer">this dummy project</a> and trying to make it work locally via <code>Skaffold</code>.</p>
<p>There are 3 services in my project (running on ports <code>3001</code>, <code>3002</code> and <code>3003</code> respectively), wired via <code>NATS server</code>.</p>
<p>The problem is: I get different kinds of errors each time I run <code>skaffold debug</code>, and one/more service(s) don't work.</p>
<p>At times, I don't get any errors, and all services work as expected. The followings are some of the errors:</p>
<pre><code>Waited for &lt;...&gt;s due to client-side throttling, not priority and fairness,
request: GET:https://kubernetes.docker.internal:6443/api/v1/namespaces/default/pods?labelSelector=app%!D(MISSING). &lt;...&gt;%!C(MISSING)app.kubernetes.io%!F(MISSING)managed-by%!D(MISSING)skaffold%!C(MISSING)skaffold.dev%!F(MISSING)run-id%!D(MISSING)&lt;...&gt;` (from `request.go:668`)
- `0/1 nodes are available: 1 Insufficient cpu.` (from deployments)
- `UnhandledPromiseRejectionWarning: NatsError: CONNECTION_REFUSED` (from apps)
- `UnhandledPromiseRejectionWarning: Error: getaddrinfo EAI_AGAIN nats-service` (from apps)
</code></pre>
<p>I'm at a loss and can't help myself anymore. I hope someone here will be able to help me out.</p>
<p>Thanks in advance.</p>

<p>I use WSL2 (Debian) and <code>docker-desktop</code> is the context of Kubernetes.</p>

<p>The error say it all:</p>
<pre><code>- `0/1 nodes are available: 1 Insufficient cpu.` (from deployments)
</code></pre>
<p>You are requesting or deploying more apps than your node can handle.<br />
In your deployment units (<code>Deployment</code>, <code>StatefulSet</code>, <code>DeamoSet</code> etc) you define the resources which you require for your application, for example in this pod:</p>
<pre class="lang-yaml prettyprint-override"><code>apiVersion: v1
kind: Pod
metadata:
  name: frontend
spec:
  containers:
  - name: app
    image: images.my-company.example/app:v4
    resources:
      requests:
        memory: &quot;64Mi&quot;
        cpu: &quot;250m&quot;
      limits:
        memory: &quot;128Mi&quot;
        cpu: &quot;500m&quot;
  - name: log-aggregator

    resources:
      requests:

      limits:
        memory: &quot;128Mi&quot;
        cpu: &quot;500m&quot;

<p>This is the relevant section:</p>
<pre class="lang-yaml prettyprint-override"><code>resources:
      requests:
        memory: &quot;64Mi&quot;
        cpu: &quot;250m&quot;

        cpu: &quot;500m&quot;

<p>Check your node resources and increase your nodes or resources in order to be able to deploy more services.</p>
