Vendor data cache being referenced on new instance

Postby gbonk » 2018/04/19 16:48:28

I'm working on Centos 6.9, and since I have not been able to find a RPM of Cloud Init 18.2 I decided to build one my self in AWS.

I run the following....

python build


python install --init-system sysvinit

then I do some chkconfig to enable the services. Cloud init runs great.... the first time.

The second time I launch a new AMI I get the following error messages

Code: Select all

2018-04-18 21:40:15,473 -[DEBUG]: Running command ['ip', '-4', 'addr', 'show'] with allowed return codes [0] (shell=False, capture=True)
2018-04-18 21:40:15,476 -[DEBUG]: unable to do any work for renaming of [['06:20:32:31:e3:9c', 'eth0', 'vif', None]]
2018-04-18 21:40:15,572 -[WARNING]: Failed to rename devices: [nic not present] Cannot rename mac=06:20:32:31:e3:9c to eth0, not available.
2018-04-18 21:40:15,572 -[DEBUG]: not a new instance. network config is not applied.

EARLIER... in the debug log I see a few clues.

Code: Select all[DEBUG]: start: init-local/check-cache: attempting to read from cache [check][DEBUG]: Reading from /var/lib/cloud/instance/obj.pkl (quiet=False)[DEBUG]: Read 8117 bytes from /var/lib/cloud/instance/obj.pkl[DEBUG]: Reading from /run/cloud-init/.instance-id (quiet=False)[DEBUG]: Read 20 bytes from /run/cloud-init/.instance-id[DEBUG]: restored from cache with run check: DataSourceEc2[DEBUG]: finish: init-local/check-cache: SUCCESS: restored from cache with run check: DataSourceEc2

BUT this is a new instance and it shouldn't even look at the cache or .instance-id file. The instance ID file does not contain the actual AWS Instance id

Is there a way to disable the caching mechanism, or is there something else since I'm building cloud-init from source ?
