Is it possible to use DevStack to install OpenStack, including Neutron,
so that OpenStack can make a VM that can communicate with the world
beyond OpenStack? I am looking for a simple localrc or local.conf that
will do this.
Let us take a concrete example. Suppose I have a machine with one NIC,
at 10.84.133.238/28. It has a simple routing table: one entry for the
local subnet, one default route through a gateway at 10.84.133.225. I
have nothing else on the 10.84.133.238/28 subnet, I can use the other
addresses (aside from .224 and .239) for VMs. What do I put in my
localrc? Do I have to fix up anything after stack.sh completes?
Once I have a working OpenStack, the remaining questions are about how
to use it to create a VM with the desired ability. That would be as the
demo user, in the demo tenant, right? I would need a security group
that allows the desired communication, of course. Create the VM on the
private net, give it a floating IP on the public network. Any tricks
missed here?
Does it matter whether my machine at 10.84.133.238 is a bare metal
machine or a VM in some undercloud?
Does it matter whether my machine has multiple ethN interfaces that have
been bonded to make the interface (named bond0) in use?
For your first attempt you can probably make a simple set of changes to
local.conf and just run the stack setup:
$ cd devstack
$ vi local.conf
$ cat local.conf
[[local|localrc]]
ADMIN_PASSWORD=password
MYSQL_PASSWORD=password
RABBIT_PASSWORD=password
SERVICE_PASSWORD=password
SERVICE_TOKEN=tokentoken
ENABLED_SERVICES+=,-n-net
ENABLED_SERVICES+=,-n-obj
ENABLED_SERVICES+=,q-svc,q-agt,q-dhcp,q-l3,q-meta
ENABLED_SERVICES+=,-n-novnc,-n-xvnc
SWIFT_HASH=12go358snjw24501
LOGFILE=$DEST/logs/stack.sh.log
VERBOSE=True
SCREEN_LOGDIR=$DEST/logs/screen
$ ./stack.sh
It creates some demo networks for you and is pretty much good to go out
the box.
