The change made here seems to be having fallout at
https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/1906187
** Description changed:
== Short summary ==
- In lxd containers launched by juju,
+ In lxd containers launched by juju,
/var/lib/cloud/seed/nocloud-net/network-config has:
- has:
- network:
- config: disabled
+ has:
+ network:
+ config: disabled
That is invalid content. Cloud-init assumes content in 'network-config'
is already namespaced to 'network'. The correct content would be:
- config: disabled
+ config: disabled
== Easy recreate ==
$ lxc launch ubuntu-daily:bionic \
- "--config=user.network-config={'network': {'config': {'disabled'}}}"
+ "--config=user.network-config={'network': {'config': {'disabled'}}}"
== Longer Info ==
When looking at bug 1651497, I see containers that run cloud-init
- have errors in a container's cloud-init log
+ have errors in a container's cloud-init log
(http://paste.ubuntu.com/p/5mKXC8pMwH/) like:
- AttributeError: 'NoneType' object has no attribute 'iter_interfaces'
+ AttributeError: 'NoneType' object has no attribute 'iter_interfaces'
and
- Failed to rename devices: Failed to apply network config names. Found bad
network config version: None
+ Failed to rename devices: Failed to apply network config names. Found bad
network config version: None
After some looking guessing I realized that juju must be attempting to
disable cloud-init's network configuration via sending the following
into the nocloud seed (/var/lib/cloud/seed/nocloud-net/network-config)
via 'user.network-config'.
cloud-init can clearly handle this better, but juju should not be
sending invalid configuration.
