Hi,
I have a host running Debian Bullseye (Podman v3.0.1). On that host, I run an OPNsense VM
via KVM. The goal is to create a (virtual) network connection between that VM and one or
more Podman containers.
So far, I have created a dedicated bridge network for the VM via this network definition:
<network connections='1'>
<name>services</name>
<uuid>884d7543-91b0-4752-93b7-7efc6633d733</uuid>
<bridge name='virbr1' stp='on' delay='0'/>
<mac address='52:54:00:78:f8:79'/>
<ip address='192.168.50.1' netmask='255.255.255.0'>
</ip>
</network>
I then created this network for Podman:
[
{
"cniVersion": "0.4.0",
"name": "services",
"plugins": [
{
"ipam": {
"gateway": "192.168.50.2",
"routes": [
{
"dst": "0.0.0.0/0"
}
],
"subnet": "192.168.50.0/24",
"type": "host-local"
},
"master": "virbr1",
"type": "macvlan"
}
]
}
]
The container is is started like so:
podman run --network=services --ip=192.168.50.10 [...]
This does work, however, it doesn't seem ideal. Is there a better way to achieve
networking between VM and containers? Is there a way to make Podman actually configure
networking by making DHCP requests (to the OPNsense VM)? That way, DNS would be configured
properly as well.
Any pointers are welcome 😄
Thanks, Sven
