Document the resolv.conf handling for the default host-local IPAM #43

Open radekg opened 3 years ago

radekg commented 3 years ago

The user can specify a bridge specific resolv.conf file with custom nameservers configured: https://www.cni.dev/plugins/current/ipam/host-local/. Example:

{
  "ipam": {
        "type": "host-local",
        "subnet": "3ffe:ffff:0:01ff::/64",
        "rangeStart": "3ffe:ffff:0:01ff::0010",
        "rangeEnd": "3ffe:ffff:0:01ff::0020",
        "routes": [
            { "dst": "3ffe:ffff:0:01ff::1/64" }
        ],
        "resolvConf": "/etc/resolv.conf"
    }
}

The contents of this resolv.conf are passed to the VM so it is not necessary to handle resolv.conf in vminit. Document.
