podman-generate-kube - Generate Kubernetes YAML based on a pod or container
podman generate kube [options] container | pod
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).
--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.
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.
