Podman : Podman Network2026/05/07

	This is the basic usage to configure Podman Network.
[1]	When running containers without specifying network, default [podman] network is assigned.

# display network list

root@dlp:~#

podman network ls

NETWORK ID    NAME        DRIVER
2f259bab93aa  podman      bridge

# display details of [podman]

root@dlp:~#

podman network inspect podman

# [podman] is assigned as container network by default

root@dlp:~#

podman run ubuntu /bin/bash -c "apt-get update; apt-get -y install iproute2; ip route"

.....
.....
default via 10.88.0.1 dev eth0 proto static metric 100
10.88.0.0/16 dev eth0 proto kernel scope link src 10.88.0.2

root@dlp:~#

podman commit $(podman ps -a | tail -1 | awk '{print $1}') srv.world/iproute

[2]	If you'd like to assign another network, configure like follows.

# create network [network01] with [192.168.100.0/24] subnet

root@dlp:~#

podman network create --subnet 192.168.100.0/24 network01

network01

root@dlp:~#

podman network ls

NETWORK ID    NAME        DRIVER
d77a05b37d25  network01   bridge
2f259bab93aa  podman      bridge

# run a container with specifying [network01]

root@dlp:~#

podman run --network network01 srv.world/iproute /usr/sbin/ip route

default via 192.168.100.1 dev eth0 proto static metric 100 e /usr/sbin/ip route
192.168.100.0/24 dev eth0 proto kernel scope link src 192.168.100.3

# to attach the network to existing running container, set like follows

root@dlp:~#

podman ps

# attach network to specify an IP address in the subnet

podman network connect network01 121b8cac13d1

# to disconnect the network, set like follows

root@dlp:~#

podman network disconnect network01 121b8cac13d1

[3]	To remove podman networks, set like follows.

root@dlp:~#

podman network ls

NETWORK ID    NAME        DRIVER
d77a05b37d25  network01   bridge
2f259bab93aa  podman      bridge

# remove [network01]

root@dlp:~#

podman network rm network01

Error: "network01" has associated containers with it. Use -f to forcibly delete containers and pods: network is being used

# force remove containers with [-f] option

root@dlp:~#

podman network rm -f network01

network01
