<p>I'm trying to deploy a knative service in my local Kubernetes cluster (Docker Desktop for windows).
I could create a knative service when I use images from the google cloud container registry (gcr.io/knative-samples/helloworld-go) but I'm facing an issue when I use images from the docker hub. Please note that I not using any private repository in the Docker registry.</p>
<p>The revision.serving will be in status <strong>unknown</strong> for the first 10 minutes and later changes to false with the reason <strong>ProgressDeadlineExceeded</strong>. The knative service fails with reason <strong>RevisionMissing</strong>. I have tried using the official hello-world image from docker hub and the response is the same.
The issue is only when I'm using images from the docker official registry but now when GCR is used.</p>
<p>Below is the Kubernetes manifest file I used to create a knative service.</p>
<pre><code>apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: **********
spec:
  template:
    metadata:
      # This is the name of our new &quot;Revision,&quot; it must follow the convention {service-name}-{revision-name}
      name: *******-rev1
    spec:
      containers:
        - image: docker.io/*****/****:v1
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 3007
</code></pre>

<p>Note: I'm using knative-serving version 1.0
Edit: (I have hidden image name)</p>
<p><a href="https://i.stack.imgur.com/xaqY1.png" rel="nofollow noreferrer">status of revision.serving</a></p>

<p>Finally, I resolved the issue by removing the ports session in the YAML file. If the container port is included, the application gets started in a container (I have verified the logs) but it never receives the traffic and fails with the ProgressDeadlineExceeded error.</p>
