Cloud provider VM name length limit
Hi All,
I can see that we have predefined limits for VM names length for some of
the cloud providers [1].
vCloud's limit is only 24 chars. My quick google check revealed that it
should be 128 chars.
Do you remember what caused the need for the lower limit on vCloud (max
24 chars) ?
Regards,
Yavor

Not aware of any of them, specifically, but I'm pretty sure that if the
JcloudsMachineNamer contains that we probably hit that problem at least
once.

I think you can just override the default using the brooklyn.properties
because you know that it will work on your vCloud installation, I think.
My two cents,
Andrea

Hi Andrea,
Thanks for the answer.
It can be 128 chars by default according to VMWare docs [1].
Are there clouds providers that lower the default limits for vCloud?
My intention is to slightly increase the limit. It may be the same
length as for GCE
I'm trying to embed a timestamp in the instance's name [2]. It requires
4 chars more.
Regards,
Yavor

Hi Yavor,
I think this is a sensible default for some vCloud installation, but you
may want to add this extra property to your brooklyn.properties
vmNameMaxLength=128
to override that default in your named location, maybe.
Hope this helps,
Andrea
