The CIDR of the bridge can't be changed (network with name bridge already exists)

[AkihiroSuda]

I tried to modify the network config with just nerdctl, but it looks like there is no way to edit an existing network, and I can't delete the bridge network; it is being recreated right away:

$ nerdctl network rm bridge
bridge
$ nerdctl network create bridge --gateway 10.10.10.1 --subnet 10.10.10.0/24
FATA[0000] network with name bridge already exists
$ nerdctl network inspect bridge
[
    {
        "Name": "bridge",
        "Id": "17f29b073143d8cd97b5bbe492bdeffec1c5fee55cc1fe2112c8b9335f8b6121",
        "IPAM": {
            "Config": [
                {
                    "Subnet": "10.4.0.0/24",
                    "Gateway": "10.4.0.1"
                }
            ]
        },
        "Labels": {}
    }
]

Seems regression in v0.22.1

• use free subnet to create network #1245

like #1425, If we allow people to change the CIDR of a network configuration, I think it would be better to validate if there is any container existed related with this network

Yes, it should be validated

I believe that we have to exclude e.ensureDefaultNetworkConfig() From NewCNIEnv(cniPath, cniConfPath string). I take this ticket
