+# NAME
+podman-generate-kube - Generate Kubernetes YAML
+
+# SYNOPSIS
+**podman generate kube **
+[**-h**|**--help**]
+[**-s**][**--service**]
+CONTAINER|POD
+
+# DESCRIPTION
+**podman generate kube** will generate Kubernetes Pod YAML (v1 specification) from a podman container or pod. Whether
+the input is for a container or pod, Podman will always generate the specification as a Pod. The input may be in the form
+of a pod or container name or ID.
+
+The **service** option can be used to generate a Service specification for the corresponding Pod ouput. In particular,
+if the object has portmap bindings, the service specification will include a NodePort declaration to expose the service. A
+random port is assigned by Podman in the specification.
+
+# OPTIONS:
+
+**s** **--service**
+Generate a service file for the resulting Pod YAML.
+
+## Examples ##
+
+Create Kubernetes Pod YAML for a container called `some-mariadb` .
+```
+$ sudo podman generate kube some-mariadb
+# Generation of Kubenetes YAML is still under development!
+#
+# Save the output of this file and use kubectl create -f to import
+# it into Kubernetes.
+#
+# Created with podman-0.11.2-dev
