github.com/containers/podman/v5@v5.1.0-rc1/transfer.md (about) 1  2 # Podman Usage Transfer 3 4 This document outlines useful information for ops and dev transfer as it relates to infrastructure that utilizes `Podman`. 5 6 ## Operational Transfer 7 8 ## Abstract 9 10 Podman is a tool for managing Pods, Containers, and Container Images. The CLI 11 for Podman is based on the Docker CLI, although Podman does not require a 12 runtime daemon to be running in order to function. Podman also supports the Docker API via the Podman socket activated system service. 13 14 ## System Tools 15 16 Many traditional tools will still be useful, such as `pstree`, `nsenter` and `lsns`. 17 As well as some systemd helpers like `systemd-cgls` and `systemd-cgtop` are still just as applicable. 18 19 ## Equivalents 20 21 For many troubleshooting and information collection steps, there may be an existing pattern. 22 Following provides equivalent with `Podman` tools for gathering information or jumping into containers, for operational use. 23 24 ## Development Transfer 25 26 There are other equivalents for these tools 27 28 | Existing Step | `Podman` (and friends) | 29 | :--- | :--- | 30 | `docker ` | [`podman`](./docs/source/markdown/podman.1.md) | 31 | `docker attach` | [`podman

Description | 110 | :--- | :--- | 111 | `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.| 112 | `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.| 113 114 ## Missing commands in podman 115 116 Those Docker commands currently do not have equivalents in `podman`: 117 118 | Missing command | Description| 119 | :--- | :--- | 120 | `docker builder` || 121 | `docker buildx` || 122 | `docker config` || 123 | `docker context` || 124 | `docker container update` | podman does not support altering running containers. We recommend recreating containers with the correct arguments.| 125 | `docker node` || 126 | `docker plugin` | podman does not support plugins. We recommend you use alternative OCI Runtimes or OCI Runtime Hooks to alter behavior of podman.| 127 | `docker stack` || 128 | `docker swarm` | podman does not support swarm. We support Kubernetes for orchestration using [CRI-O](https://github.com/cri-o/cri-o).| 129 | `docker trust` |[`podman image trust`](./docs/source/markdown/podman-image-trust.1.md) | 130 | `docker
