cloud-init service is set to start before NetworkManager service starts,
|
||
|
|
but this does not avoid a race condition between them. NetworkManager
|
||
|
|
starts before cloud-init can write `dns=none' to the file:
|
||
|
|
/etc/NetworkManager/conf.d/99-cloud-init.conf. This way NetworkManager
|
||
|
|
doesn't read the configuration and erases all resolv.conf values upon
|
||
|
|
shutdown. On the next reboot neither cloud-init or NetworkManager will
|
||
|
|
write anything to resolv.conf, leaving it blank.
|
||
|
|
|
||
|
|
This patch introduces a NM reload (try-restart) at the end of cloud-init
|
||
|
|
start up so it won't erase resolv.conf upon first shutdown.

cloud-init.service needs to wait until network is fully up before
|
||
|
|
continuing executing and configuring its service.

The configuration option ssh_deletekeys will trigger the generation

of new ssh keys for every new instance deployed.
