<p>I have a Oracle OCI Kubernetes Cluster. I tested a sample nginx with Loadbalancer and it works fine and can access externally. Now I have a DB &amp; Weblogic docker container image on my Local machine(not on cluster nodes). When I try to deploy them I get an error saying it is not found in registry. I haven't uploaded the image to registry. My question is, is there a way to directly reference the image on my local box running kubectl and deploy it ?</p>

<p>sample nginx works</p>

<p>No.  You all but have to be running or have access to a Docker registry server to use Kubernetes.</p>

<p>You can't directly download things from other systems' Docker daemons.  Kubernetes doesn't even store images within the cluster: when a pod spec has an <code>image:</code>, each individual node that runs it separately goes off and retrieves the image content.  The upshot of this is that you have to upload your image to <em>somewhere</em>, so that the Kubernetes nodes can download it, and that "somewhere" is a Docker registry service (Docker Hub, a privately-run registry, cloud services like Amazon ECR, ...).</p>

<p>The various Kubernetes-on-your-workstation installations (minikube, kind, ...) generally have some way to either directly use the Kubernetes node's Docker daemon or upload an image into "the cluster", but that doesn't sound like the situation you have.</p>
