Coreos ignition with remote config fails because of the network

[Jorge Sevilla Cedillo]

Hi!

I'm trying to boot my coreOS ova image in VSphere by using customize ignition data which is allocated in a remote file (in S3 amazon). Unfortunatelly I get always the same error:

GET error: Get https://s3-use-west-2.amazonaws.com/...ignition.json: dial tcp: lookup s3-us-west-2.amazonaws.com on [::1]:53: read udp [::1]47112->[::1]:53: read: connection refused

My ignition file has the following data:

{
    "networkd": {
      "units": [
       {
         "contents": "[Match]\nName=eth0\n\n[Network]\nDNS=192.168.1.1\nAddress=192.168.1.1/24\nGateway=192.168.1.1",
         "name": "eth0.network"
  }
  ]
    },
    "ignition": {
        "version": "2.1.0",
        "config": {
            "replace": {
                "source": "https://s3-us-west-2.amazonaws.com/.../ignition.json"
            }
        }
    }
}

Could anyone help me??

Many thanks!

Jorge

When Ignition requires a static network configuration to download
files, kernel command-line options are used:

https://coreos.com/ignition/docs/latest/network-configuration.html#using-static-ip-addresses-with-ignition

This should allow you to include your networkd configuration in the
remote JSON file.

Thanks.

Hi David,

First of all, thank you for your fast answer.

But I do not know how to apply kernel command-line to the coreos ova image for VSphere. Could you help me with it? I would like to do it automatically, without keyboard interaction.

Many thanks,

Jorge

I am not familiar with vsphere, so I don't know what kind of interface
it has for changing these settings. The general solution would be to
modify the image's OEM partition to add a grub.cfg flie containing the
line:

set linux_append="$linux_append ip=..."

Thanks.
