Hi Marc,
With reference to setting custom host name to instances, I see a problem.
I set Server Hostname Format as:
{SCALR_FARM_NAME}-{SCALR_FARM_ROLE_ALIAS}-{SCALR_INSTANCE_INDEX}
When a VM instance gets created, instance name & hostname are set properly
as expected. But, DNS resolution fails inside the VM:
[root@DevOps-InternalInfrastructureServices-New-Host-1 ~]# hostname
DevOps-InternalInfrastructureServices-New-Host-1
[root@DevOps-InternalInfrastructureServices-New-Host-1 ~]# hostname -f
*hostname: Name or service not known*
[root@DevOps-InternalInfrastructureServices-New-Host-1 ~]# cat /etc/hosts
None DevOps-InternalInfrastructureServices-New-Host-1
127.0.0.1 localhost
Looking at the log, it appears like DNS entries are getting created for
default hostname (instead of custom host name):
