* Support for the Kubernetes CRI interface for container management.
The [CRI-O](https://github.com/cri-o/cri-o) daemon specializes in that.
-* Supporting `docker-compose`. We believe that Kubernetes is the defacto
- standard for composing Pods and for orchestrating containers, making
- Kubernetes YAML a defacto standard file format. Hence, Podman allows the
- creation and execution of Pods from a Kubernetes YAML file (see
- [podman-play-kube](https://github.com/containers/podman/blob/master/docs/source/markdown/podman-play-kube.1.md)).
- Podman can also generate Kubernetes YAML based on a container or Pod (see
- [podman-generate-kube](https://github.com/containers/podman/blob/master/docs/source/markdown/podman-generate-kube.1.md)),
- which allows for an easy transition from a local development environment
- to a production Kubernetes cluster. If Kubernetes does not fit your requirements,
- there are other third-party tools that support the docker-compose format such as
- [kompose](https://github.com/kubernetes/kompose/) and
- [podman-compose](https://github.com/muayyad-alsadi/podman-compose)
- that might be appropriate for your environment. This situation may change with
- the addition of the REST API.

+## NAME
+podman\-rename - Rename an existing container
+
+## SYNOPSIS
+**podman rename** *container* *newname*
+
+**podman container rename** *container* *newname*
+
+## DESCRIPTION
+Rename changes the name of an existing container.
+The old name will be freed, and will be available for use.
+This command can be run on containers in any state.
+However, running containers may not fully receive the effects until they are restarted - for example, a running container may still use the old name in its logs.
+At present, only containers are supported; pods and volumes cannot be renamed.
+
+## OPTIONS
+
+## EXAMPLES
+
+```
+# Rename a container by name
+$ podman rename oldContainer aNewName
+```
+
+```
+# Rename a container by ID
+$ podman rename 717716c00a6b testcontainer
+```
+
+```
+# Use the container rename alias
+$ podman container rename 6e7514b47180 databaseCtr
+```
