podman-pod-create - Create a new pod
podman pod create [options]
Creates an empty pod, or unit of multiple containers, and prepares it to have containers added to it. 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.
Add a host to the /etc/hosts file shared between all containers in the pod.
Path to cgroups under which the cgroup for the pod will be created. If the path is not absolute, the path is considered to be relative to the cgroups path of the init process. Cgroups will be created if they do not already exist.
Set custom DNS servers in the /etc/resolv.conf file that will be shared between all containers in the pod. A special option, "none" is allowed which disables creation of /etc/resolv.conf for the pod.
Set custom DNS options in the /etc/resolv.conf file that will be shared between all containers in the pod.
Set custom DNS search domains in the /etc/resolv.conf file that will be shared between all containers in the pod.
Print usage statement.
Set a hostname to the pod
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.
Write the pid of the infra container's conmon process to a file. As conmon runs in a separate process than Podman, this is necessary when using systemd to manage Podman containers and pods.
The command that will be run to start the infra container. Default: "/pause".
The image that will be created for the infra container. Default: "k8s.gcr.io/pause:3.1".
Set a static IP for the pod's shared network.
Add metadata to a pod (e.g., --label com.example.key=value).
Read in a line delimited file of labels.
Set a static MAC address for the pod's shared network.
Assign a name to the pod.
Set network mode for the pod. Supported values are -
bridge: Create a network stack on the default bridge. This is the
default for rootful containers. - host: Do not create a network
namespace, all containers in the pod will use the host's network. Note: the
host mode gives the container full access to local system services such as
D-bus and is therefore considered insecure. - Comma-separated list of the
names of CNI networks the pod should join. -
slirp4netns[:OPTIONS,...]: use slirp4netns to create a user network
stack. This is the default for rootless containers. It is possible to
specify these additional options:
- allow_host_loopback=true|false: Allow the slirp4netns to reach the
host loopback IP (10.0.2.2). Default is false.
- cidr=CIDR: Specify ip range to use for this network. (Default is
10.0.2.0/24).
- enable_ipv6=true|false: Enable IPv6. Default is false. (Required for
outbound_addr6).
- outbound_addr=INTERFACE: Specify the outbound interface slirp should
bind to (ipv4 traffic only).
- outbound_addr=IPv4: Specify the outbound ipv4 address slirp should
bind to.
- outbound_addr6=INTERFACE: Specify the outbound interface slirp
should bind to (ipv6 traffic only).
- outbound_addr6=IPv6: Specify the outbound ipv6 address slirp should
bind to.
- port_handler=rootlesskit: Use rootlesskit for port forwarding.
Default.
- port_handler=slirp4netns: Use the slirp4netns port forwarding.
Add a DNS alias for the container. When the container is joined to a CNI network with support for the dnsname plugin, the container will be accessible through this name from other containers in the network.
Disable creation of /etc/hosts for the pod.
Write the pod ID to the file.
Publish a port or range of ports from the pod to the host.
Format: ip:hostPort:containerPort | ip::containerPort | hostPort:containerPort | containerPort Both hostPort and containerPort can be specified as a range of ports. When specifying ranges for both, the number of container ports in the range must match the number of host ports in the range. Use podman port to see the actual mapping: podman port CONTAINER $CONTAINERPORT.
NOTE: This cannot be modified once the pod is created.
If another pod with the same name already exists, replace and remove it. The default is false.
A comma delimited list of kernel namespaces to share. If none or "" is specified, no namespaces will be shared. The namespaces to choose from are ipc, net, pid, uts.
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 will be generated for it. The name is useful any place you need to identify a pod.
