Title:
19.04 minimal images on GCE intermittently fail to set up networking
Status in cloud-init:
Expired
Bug description:
Related to https://bugs.launchpad.net/cloud-init/+bug/1766287 I'd like
to open a new bug following Disco minimal images failing to set up
networking due to similar reasons as lp:1766287 with the only
difference being that no nic was found.
A workaround was found to set up cloud-init service config:
/etc/systemd/system/cloud-init-local.service.d/gcp.conf
```
[Unit]
After=systemd-udev-trigger.service
[Service]
ExecStartPre=/bin/udevadm settle
```
The goal of this workaround is to:
1) ensure that cloud-init-local.service runs after
systemd-udev-trigger.service starts (this is what triggers
udev coldplug events, like plugging in the nic)
2) Run udevadm settle before we start cloud-init local so that any
nic processing is completed before cloud-init starts looking for
a nic.
Currently this is only required on minimal images but there is a
chance it could occur in base images too should they boot quick
enough. Minimal disco does not have snap preseeding as base images do and
due to snap preseeding running before cloud-init it makes it extremely
unlikely to
happen in base images.
I understand that cloud-init might not be the place to fix the issue
for all images but I'd like to re-open this bug to start that
discussion.
I have attached cloud-init logs, netplan yaml, image manifest and
sosreports from an instance that failed to set up networking.
