# NAME
podman-generate-kube - Generate Kubernetes YAML
# SYNOPSIS
**podman generate kube** [*-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.
Note that the generated Kubernetes YAML file can be used to re-run the deployment via podman-play-kube(1).
# OPTIONS:
**--service** **-s**
Generate a Kubernetes service object in addition to the Pods.
## 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.
