+# Pushing an image to your local Minikube-powered Kubernetes cluster
+
+With Podman Desktop, you can push an image to your local Minikube-powered Kubernetes cluster.
+
+#### Prerequisites
+
+- [You onboarded a container engine](/docs/containers).
+- [You onboarded a Minikube cluster](/docs/minikube).
+- [You have set your Kubernetes context to your Minikube cluster](/docs/minikube/working-with-your-local-minikube-cluster).
+- Your image is available on the **Images** page: `<my_image>:<my_tag>`.
+
+#### Procedure
+
+1. Open **Podman Desktop dashboard > <Icon icon="fa-solid fa-cloud" size="lg" /> Images**.
+1. **<Icon icon="fa-solid fa-search" size="lg" /> Search images**: `<your_image>:<your_tag>`.
+1. Click **<Icon icon="fa-solid fa-ellipsis-v" size="lg" /> > <Icon icon="fa-solid fa-ellipsis-v" size="lg" /> Push image to Minikube cluster**.
+1. If you created many Minikube clusters, select your Minikube cluster from the list.
+
+#### Verification
+
+Minikube enables you to list loaded images, using:
+
+```command
+$ minikube image list
+```
+
+You can also create a Pod that uses the loaded image:
+
+1. Create a `verify_my_image.yaml` Kubernetes YAML file on your workstation.
+   Replace the placeholders:
+
+   - Pod `name` and container `name` value must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character.
+   - Container `image` value is the image you pushed.
+
+   ```yaml
+   apiVersion: v1
+   kind: Pod
+   metadata:
+     name: <verify-my-image>
+   spec:
+     containers:
+       - name: <my-image>
+         image: <my_image>:<my_tag>
+         imagePullPolicy: Never
+   ```
+
+1. Open **<Icon icon="fa-solid fa-cubes" size="lg" /> Pods > Play Kubernetes YAML**.
+   1. **Kubernetes YAML file**: select your `verify_my_image.yaml` file.
+   1. **Select Runtime**: **Using a Kubernetes cluster**.
+   1. Click **Play**.
+   1. Click **Done**
+1. Open **<Icon icon="fa-solid fa-cubes" size="lg" /> Pods**.
+1. **<Icon icon="fa-solid fa-search" size="lg" /> Search pods**: `<verify-my-image>`.
+1. The pod **Status** is **Running**.
