% podman-generate-kube(1)
## NAME
podman-generate-kube - Generate Kubernetes YAML based on a pod or container

## SYNOPSIS
**podman generate kube** [*options*] *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.

Note that the generated Kubernetes YAML file can be used to re-run the deployment via podman-play-kube(1).

## OPTIONS

**--filename**, **-f**=**filename**

Output to the given file, instead of STDOUT. If the file already exists, `generate kube` will refuse to replace it and return an error.

**--service**, **-s**

Generate a Kubernetes service object in addition to the Pods. Used to generate a Service specification for the corresponding Pod output. 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.

## 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
