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. 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 | Existing Step | `Podman` (and friends) | 25 | :--- | :--- | 26 | `docker run` | [`podman run`](./docs/podman-run.1.md) | 27 | `docker exec` | [`podman exec`](./docs/podman-exec.1.md) | 28 | `docker info` | [`podman info`](./docs/podman-info.1.md) | 29 | `docker inspect` | [`podman inspect`](./docs/podman-inspect.1.md) | 30 | `docker logs` | [`podman logs`](./docs/podman-logs.1.md) | 31 | `docker ps` | [`podman ps`](./docs/podman-ps.1.md) | 32 | `docker stats`| [`podman stats`](./docs/podman-stats.1.md)| 33 34 ## Development Transfer 35 36 There are other equivalents for these tools 37 38 | Existing Step | `Podman` (and friends) | 39 | :--- | :--- | 40 | `docker attach` | [`podman attach`](./docs/podman-attach.1.md) | 41 | `docker cp` | [`podman cp`](./docs/podman-cp.1.md) | 42 | `docker build` | [`podman build`](./docs/podman-build.1.md) | 43 | `docker commit` | [`podman commit`](./docs/podman-commit.1.md) | 44 | `docker container`|[`podman container`](./docs/podman-container.1.md) | 45 | `docker create` | [`podman create`](./docs/podman-create.1.md) | 46 | `docker diff` | [`podman diff`](./docs/podman-diff.1.md) | 47 | `docker events` | [`podman events`](./docs/podman-events.1.md) | 48 | `docker export` | [`podman export`](./docs/podman-export.1.md) | 49 | `docker history` | [`podman history`](./docs/podman-history.1.md) | 50 | `docker image` | [`podman image`](./docs/podman-image.1.md) | 51 | `docker images` | [`podman images`](./docs/podman-images.1.md) | 52 | `docker import` | [`podman import`](./docs/podman-import.1.md) | 53 | `docker kill` | [`podman kill`](./docs/podman-kill.1.md) | 54 | `docker load` | [`podman load`](./docs/podman-load.1.md) | 55 | `docker login` | [`podman login`](./docs/podman-login.1.md) | 56 | `docker logout` | [`podman logout`](./docs/podman-logout.1.md) | 57 | `docker pause` | [`podman pause`](./docs/podman-pause.1.md) | 58 | `docker ps` | [`podman ps`](./docs/podman-ps.1.md) | 59 | `docker pull` | [`podman pull`](./docs/podman-pull.1.md) | 60 | `docker push` | [`podman push`](./docs/podman-push.1.md) | 61 | `docker port` | [`podman port`](./docs/podman-port.1.md) | 62 | `docker restart` | [`podman restart`](./docs/podman-restart.1.md) | 63 | `docker rm` | [`podman rm`](./docs/podman-rm.1.md) | 64 | `docker rmi` | [`podman rmi`](./docs/podman-rmi.1.md) | 65 | `docker run` | [`podman run`](./docs/podman-run.1.md) | 66 | `docker save` | [`podman save`](./docs/podman-save.1.md) | 67 | `docker search` | [`podman search`](./docs/podman-search.1.md) | 68 | `docker start` | [`podman start`](./docs/podman-start.1.md) | 69 | `docker stop` | [`podman stop`](./docs/podman-stop.1.md) | 70 | `docker tag` | [`podman tag`](./docs/podman-tag.1.md) | 71 | `docker top` | [`podman top`](./docs/podman-top.1.md) | 72 | `docker unpause` | [`podman unpause`](./docs/podman-unpause.1.md) | 73 | `docker version` | [`podman version`](./docs/podman-version.1.md) | 74 | `docker volume` | [`podman volume`](./docs/podman-volume.1.md) | 75 | `docker volume create` | [`podman volume create`](./docs/podman-volume-create.1.md) | 76 | `docker volume inspect`| [`podman volume inspect`](./docs/podman-volume-inspect.1.md)| 77 | `docker volume ls` | [`podman volume ls`](./docs/podman-volume-ls.1.md) | 78 | `docker volume prune` | [`podman volume prune`](./docs/podman-volume-prune.1.md) | 79 | `docker volume rm` | [`podman volume rm`](./docs/podman-volume-rm.1.md) | 80 | `docker system` | [`podman system`](./docs/podman-system.1.md) | 81 | `docker system df` | [`podman system df`](./docs/podman-system-df.1.md) | 82 | `docker system prune` | [`podman system prune`](./docs/podman-system-prune.1.md) | 83 | `docker system info` | [`podman system info`](./docs/podman-system-info.1.md) | 84 | `docker wait` | [`podman wait`](./docs/podman-wait.1.md) | 85 86 **** Use mount to take advantage of the entire linux tool chain rather then just cp. Read [`here`](./docs/podman-cp.1.md) for more information. 87 88 ## Missing commands in podman 89 90 Those Docker commands currently do not have equivalents in `podman`: 91 92 | Missing command | Description| 93 | :--- | :--- | 94 | `docker container update` | podman does not support altering running containers. We recommend recreating containers with the correct arguments.| 95 | `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.| 96 | `docker network` || 97 | `docker node` || 98 | `docker plugin` | podman does not support plugins. We recommend you use alternative OCI Runtimes or OCI Runtime Hooks to alter behavior of podman.| 99 | `docker secret` || 100 | `docker service` || 101 | `docker stack` || 102 | `docker swarm` | podman does not support swarm. We support Kubernetes for orchestration using [CRI-O](https://github.com/cri-o/cri-o).| 103 | `docker volume` | podman currently supports file volumes. Future enhancement planned to support Docker Volumes Plugins 104 105 ## Missing commands in Docker 106 107 The following podman commands do not have a Docker equivalent: 108 109 * [`podman generate`](./docs/podman-generate.1.md) 110 * [`podman generate kube`](./docs/podman-generate-kube.1.md) 111 * [`podman container checkpoint`](/docs/podman-container-checkpoint.1.md) 112 * [`podman container cleanup`](/docs/podman-container-cleanup.1.md) 113 * [`podman container exists`](/docs/podman-container-exists.1.md) 114 * [`podman container refresh`](/docs/podman-container-refresh.1.md) 115 * [`podman container runlabel`](/docs/podman-container-runlabel.1.md) 116 * [`podman container restore`](/docs/podman-container-restore.1.md) 117 * [`podman healthcheck run`](/docs/podman-healthcheck-run.1.md) 118 * [`podman image exists`](./docs/podman-image-exists.1.md) 119 * [`podman image sign`](./docs/podman-image-sign.1.md) 120 * [`podman image trust`](./docs/podman-image-trust.1.md) 121 * [`podman mount`](./docs/podman-mount.1.md) 122 * [`podman play`](./docs/podman-play.1.md) 123 * [`podman play kube`](./docs/podman-play-kube.1.md) 124 * [`podman pod`](./docs/podman-pod.1.md) 125 * [`podman pod create`](./docs/podman-pod-create.1.md) 126 * [`podman pod exists`](./docs/podman-pod-exists.1.md) 127 * [`podman pod inspect`](./docs/podman-pod-inspect.1.md) 128 * [`podman pod kill`](./docs/podman-pod-kill.1.md) 129 * [`podman pod pause`](./docs/podman-pod-pause.1.md) 130 * [`podman pod ps`](./docs/podman-pod-ps.1.md) 131 * [`podman pod restart`](./docs/podman-pod-restart.1.md) 132 * [`podman pod rm`](./docs/podman-pod-rm.1.md) 133 * [`podman pod start`](./docs/podman-pod-start.1.md) 134 * [`podman pod stop`](./docs/podman-pod-stop.1.md) 135 * [`podman pod top`](./docs/podman-pod-top.1.md) 136 * [`podman pod unpause`](./docs/podman-pod-unpause.1.md) 137 * [`podman varlink`](./docs/podman-varlink.1.md) 138 * [`podman umount`](./docs/podman-umount.1.md)
