# Podman Usage Transfer
This document outlines useful information for ops and dev transfer as it relates to infrastructure that utilizes `Podman`.
## Operational Transfer
## Abstract
Podman is a tool for managing Pods, Containers, and Container Images. The CLI
for Podman is based on the Docker CLI, although Podman does not require a
runtime daemon to be running in order to function.
## System Tools
Many traditional tools will still be useful, such as `pstree`, `nsenter` and `lsns`.
As well as some systemd helpers like `systemd-cgls` and `systemd-cgtop` are still just as applicable.
## Equivalents
For many troubleshooting and information collection steps, there may be an existing pattern.
Following provides equivalent with `Podman` tools for gathering information or jumping into containers, for operational use.
| Existing Step | `Podman` (and friends) |

## Missing commands in podman
Those Docker commands currently do not have equivalents in `podman`:
| Missing command | Description|
| :--- | :--- |
| `docker container rename` | podman does not support `container rename` - or the `rename` shorthand. We recommend using `podman rm` and `podman create` to create a container with a specific name.|
| `docker container update` | podman does not support altering running containers. We recommend recreating containers with the correct arguments.|
| `docker node` ||
| `docker plugin` | podman does not support plugins. We recommend you use alternative OCI Runtimes or OCI Runtime Hooks to alter behavior of podman.|
| `docker secret` ||
| `docker service` ||
| `docker stack` ||
| `docker swarm` | podman does not support swarm. We support Kubernetes for orchestration using [CRI-O](https://github.com/cri-o/cri-o).|
