Unable to fetch remote ignition config - Flatcar

[Alexander von Gluck]

Feature Request

Users should be able to use a remote ignition configuration.

Environment

• Bare Metal, Flatcar stable
• coreos-install -d /dev/nvme1n1 -i kickoff-nas.ign
  • https://raw.githubusercontent.com/kallisti5/ignition/main/ign/kickoff-nas.ign
• Reboot
  • "Failed to fetch config: resource requires networking"
  • GET error: Get "https://raw......"

Desired Feature

• It should be possible to fetch a remote config. A networking card supported by flatcar is installed... however networking seems to be inactive while processing pre-packed ignition configs?

Other Information

[Jonathan Lebon]

Ignition indeed supports fetching remote resources. The error message you're getting should be non-fatal; it's part of the infrastructure for conditional networking (see #956 for details). That error means that offline fetching was attempted but failed and that full networking is required. If the OS is configured correctly, this should signal to the initramfs to bring up networking and try fetching again. The details here depend on the OS, so I'll let Flatcar devs chime in here. @pothos perhaps?

It'd also help if you could post the full console logs if possible.

Thanks, yes, I've answered in flatcar/Flatcar#908 (comment) and agree that it should work and we need more logs to know why network configuration failed.

Thanks for chiming in! Let's keep this tracked in the flatcar issue then. If it turns out to be an Ignition issue, we can re-open this one or a new one.
