The right way to set hostname in RHEL7 is:
|
|
|
18322d |
|
|
|
18322d |
$ hostnamectl set-hostname HOSTNAME
|
|
|
18322d |
|
|
|
18322d |
DataSourceAzure, however, uses:
|
|
|
18322d |
$ hostname HOSTSNAME
|
|
|
18322d |
|
|
|
18322d |
instead and this causes problems. We can't simply change
|
|
|
18322d |
'BUILTIN_DS_CONFIG' in DataSourceAzure.py as 'hostname' is being used
|
|
|
18322d |
for both getting and setting the hostname.
|
|
|
18322d |
|
|
|
18322d |
Long term, this should be fixed in a different way. Cloud-init
|
|
|
18322d |
has distro-specific hostname setting/getting (see
|
|
|
18322d |
cloudinit/distros/rhel.py) and DataSourceAzure.py needs to be switched
|
|
|
18322d |
to use these.

|
