Hi,
depending on your workflow there would be a way with scripting [0],
not sure if this would be a suitable approach for you.
There also has been a blueprint [1] for the selection of subnets
during instance creation since Juno, but I can't find anything about
an implementation.

Zitat von Hang Yang <skinny...@gmail.com>:
Hi there,
I have one question about choosing a specific subnet when boot a vm. My
OpenStack cluster is in Queens and I have multiple subnets in one network.
What I want is when I issue a boot command the instance only gets ip from
one subnet by default. I know there is a way to achieve that by creating a
port with --fixed-ip subnet=xxx then pass the port id to boot command.
Wondering if there is another way that does not need manually create the
port? Is there any configuration I can do to make it default for Neutron to
only pick one subnet from a network in boot?
Thanks for any help.
Best regards,
Hang
