## NAME
podman\-pod\-create - Create a new pod

## SYNOPSIS
**podman pod create** [*options*] [*name*]

## DESCRIPTION

Creates an empty pod, or unit of multiple containers, and prepares it to have
containers added to it. The pod can be created with a specific name. If a name
is not given a random name is generated. The pod ID is printed to STDOUT. You
can then use **podman create --pod `<pod_id|pod_name>` ...** to add containers
to the pod, and **podman pod start `<pod_id|pod_name>`** to start the pod.

The operator can identify a pod in three ways:
UUID long identifier (“f78375b1c487e03c9438c729345e54db9d20cfa2ac1fc3494b6eb60872e74778”)
UUID short identifier (“f78375b1c487”)
Name (“jonah”)

podman generates a UUID for each pod, and if a name is not assigned
to the container with **--name** then a random string name is generated
for it. This name is useful to identify a pod.

Note: resource limit related flags work by setting the limits explicitly in the pod's cgroup parent
for all containers joining the pod. A container can override the resource limits when joining a pod.
For example, if a pod was created via **podman pod create --cpus=5**, specifying **podman container create --pod=`<pod_id|pod_name>` --cpus=4** causes the container to use the smaller limit. Also, containers which specify their own cgroup, such as **--cgroupns=host**, do NOT get the assigned pod level cgroup resources.

## OPTIONS

@@option add-host

The /etc/hosts file is shared between all containers in the pod.

@@option blkio-weight

@@option blkio-weight-device

@@option cgroup-parent

@@option cpu-shares

#### **--cpus**=*amount*

Set the total number of CPUs delegated to the pod. Default is 0.000 which indicates that there is no limit on computation power.

@@option cpuset-cpus

@@option cpuset-mems

@@option device

Note: the pod implements devices by storing the initial configuration passed by the user and recreating the device on each container added to the pod.

@@option device-read-bps

@@option device-write-bps

#### **--dns**=*ipaddr*

Set custom DNS servers in the /etc/resolv.conf file that is shared between all containers in the pod. A special option, "none" is allowed which disables creation of /etc/resolv.conf for the pod.

#### **--dns-option**=*option*

Set custom DNS options in the /etc/resolv.conf file that is shared between all containers in the pod.

#### **--dns-search**=*domain*

Set custom DNS search domains in the /etc/resolv.conf file that is shared between all containers in the pod.

#### **--exit-policy**=**continue** | *stop*

Set the exit policy of the pod when the last container exits.  Supported policies are:

| Exit Policy        | Description                                                                                                                |
| ------------------ | -------------------------------------------------------------------------------------------------------------------------- |
| *continue*         | The pod continues running, by keeping its infra container alive, when the last container exits. Used by default.           |
| *stop*             | The pod (including its infra container) is stopped when the last container exits. Used in `kube play`.                     |

@@option gidmap.pod

@@option gpus

#### **--help**, **-h**

Print usage statement.

@@option hostname.pod

@@option hosts-file

#### **--infra**

Create an infra container and associate it with the pod. An infra container is a lightweight container used to coordinate the shared kernel namespace of a pod. Default: true.

@@option infra-command

@@option infra-conmon-pidfile

#### **--infra-image**=*image*

The custom image that is used for the infra container.  Unless specified, Podman builds a custom local image which does not require pulling down an image.

@@option infra-name

@@option ip

@@option ip6

@@option label

@@option label-file

@@option mac-address

@@option memory

@@option memory-swap

#### **--name**, **-n**=*name*

Assign a name to the pod.

@@option network

Invalid if using **--dns**, **--dns-option**, or **--dns-search** with **--network** set to **none** or **container:**_id_.

@@option network-alias

@@option no-hostname

@@option no-hosts

This option conflicts with **--add-host**.

@@option pid.pod

#### **--pod-id-file**=*path*

Write the pod ID to the file.

@@option publish

**Note:** You must not publish ports of containers in the pod individually,
but only by the pod itself.

**Note:** This cannot be modified once the pod is created.

@@option replace

@@option restart

Default restart policy for all the containers in a pod.

@@option security-opt

#### **--share**=*namespace*

A comma-separated list of kernel namespaces to share. If none or "" is specified, no namespaces are shared, and the infra container is not created unless explicitly specified via **--infra=true**. The namespaces to choose from are cgroup, ipc, net, pid, uts. If the option is prefixed with a "+", the namespace is appended to the default list. Otherwise, it replaces the default list. Defaults match Kubernetes default (ipc, net, uts)

#### **--share-parent**

This boolean determines whether or not all containers entering the pod use the pod as their cgroup parent. The default value of this option is true. Use the **--share** option to share the cgroup namespace rather than a cgroup parent in a pod.

Note: This option conflicts with the **--share=cgroup** option since that option sets the pod as the cgroup parent but enters the container into the same cgroupNS as the infra container.

@@option shm-size

@@option shm-size-systemd

@@option subgidname

@@option subuidname

@@option sysctl

@@option uidmap.pod

@@option userns.pod

@@option uts.pod

@@option volume

@@option volumes-from

## FOOTNOTES
<a name="Footnote1">1</a>: The Podman project is committed to inclusivity, a core value of open source. The `master` and `slave` mount propagation terminology used here is problematic and divisive, and needs to be changed. However, these terms are currently used within the Linux kernel and must be used as-is at this time. When the kernel maintainers rectify this usage, Podman will follow suit immediately.
