For cloud deployments, Ignition gathers the configuration via user-data mechanisms. CoreOS runs cloudinit a few times during the boot process. Right now this happens at each boot, but that functionality may change in the future. The first pass is the OEM cloud-init, which is baked into the image to set up networking and other features required for that provider. #cloud-config coreos: units: - name: systemd-networkd.service command: stop - name: 00-eth0.network runtime: true content: | [Match] Name=eth0 [Network] DNS=1.2.3.4 Address=10.0.0.101/24 Gateway=10.0.0.1 - name: down-interfaces.service command: start content: | [Service] Type=oneshot ExecStart=/usr/bin/ip link set eth0 down ExecStart=/usr/bin/ip addr flush dev eth0 - name: systemd-networkd.service command: restart cloud-init is powerful to inject user-data in to VM instance, and its existing module provides lots of possibility.
