# 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. Podman also supports the Docker API via the Podman socket activated system service.
## 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.
## Development Transfer
There are other equivalents for these tools

## Behavioural differences and pitfalls
These commands behave differently from the commands in Docker:
| Command | Description |
| :--- | :--- |
| `podman volume create` | While `docker volume create` is idempotent, `podman volume create` raises an error if the volume does already exist. See this [docker issue](https://github.com/moby/moby/issues/16068) for more information.|
| `podman run -v /tmp/noexist:/tmp ...` | While `docker run -v /tmp/noexist:/tmp` will create non existing volumes on the host, Podman will report that the volume does not exist. The Podman team sees this as a bug in Docker.|
## Missing commands in podman
Those Docker commands currently do not have equivalents in `podman`:
| Missing command | Description|
| :--- | :--- |
| `docker builder` ||
| `docker buildx` ||
| `docker config` ||
| `docker context` ||
| `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 stack` ||
| `docker swarm` | podman does not support swarm. We support Kubernetes for orchestration using [CRI-O](https://github.com/cri-o/cri-o).|
| `docker trust` |[`podman image trust`](./docs/source/markdown/podman-image-trust.1.md) |
| `docker update` ||
